Nano Banana Pro

1 day ago (blog.google)

Google has been stomping around like Godzilla this week, and this is the first time I decided to link my card to their AI studio.

I had seen people saying that they gave up and went to another platform because it was "impossible to pay". I thought this was strange, but after trying to get a working API key for the past half hour, I see what they mean.

Everything is set up, I see a message that says "You're using Paid API key [NanoBanano] as part of [NanoBanano]. All requests sent in this session will be charged." Go to prompt, and I get a "permission denied" error.

There is no point in having impressive models if you make it a chore for me to -give you my money-

  • First off, apologies for the bad first impression, the team is pushing super hard to make sure it is easy to access these models.

    - On permission issue, not sure I follow the flow that got you there, pls email me more details if you are able too and happy to debug: Lkilpatrick@google.com

    - On overall friction for billing: we are working on a new billing experience built right into AI Studio that will make it super easy to add a CC and go build. This will also come along with things like hard billing caps and such. The expected ETA for global rollout is January!

    • Congrats on the move to Google!

      Please allow me to rant to someone who can actually do something about this.

      Vertex AI has been a nightmare to simply sign up, link a credit card, and start using Claude Sonnet (now available on Vertex AI).

      The sheer number of steps required for this (failed) user journey is dizzying:

      * AI Studio, get API key

      * AI Studio, link payment method: Auto-creates GCP property, which is nice

      * Punts to GCP to actually create the payment method and link to GCP property

      * Try to use API key in Claude Code; need to find model name

      * Look around to find actual model name, discover it is only deployed on some regions, thankfully, the property was created on the correct region

      * Specify the new endpoint and API key, Claude Code throws API permissions errors

      * Search around Vertex and find two different places where the model must be provisioned for the account

      * Need to fill out a form to get approval to use Claude models on GCP

      * Try Claude Code again, fails with API quota errors

      * Check Vertex to find out the default quota for Sonnet 4.5 is 0 TPM (why is this a reasonable default?)

      * Apply for quota increase to 10k tokens/minute (seemingly requires manual review)

      * Get rejection email with no reasoning

      * Apply for quota increase to 1 token/minute

      * Get rejection email with no reasoning

      * Give up

      Then I went to Anthropic's own site, here's what that user journey looks like:

      * console.anthropic.com, get API key

      * Link credit card

      * Launch Claude Code, specify API key

      * Success

      I don't think this is even a preferential thing with Claude Code, since the API key is working happily in OpenCode as well.

    • When we first started using Gemini for a new product a few months ago you banned our entire GCP account from using at all Gemini in the middle of a demo to our board. Doesn't seem like things have improved all that much on the on boarding front.

    • Any chance that this reflected to our company account instead of AI Studio?

      We want to switch to Gemini from Claude (for agentic coding, chat UI, and any other employee-triggered scenarios) but the pricing model is a complete barrier: How do we pay for a monthly subscription with a capped price?

      You launched Antigravity, which looks like an amazing product that could replace Claude Code, but do I know I will be able to pay for it in the same way I pay Claude, which is a simple pay per month subscription?

    • Just make it a VSCode plugin, I don't want to install a new IDE (which is just VSCode anyway) to use your product. It might be better than claude and chatgpt5.1 but not better enough to justify me re-doing all my IDE configs.

    • The new releases this week baited me into business ultra subscription. Sadly it’s totally useless for gemini 3 cli and now also nano banana does not work. Just wow.

      1 reply →

    • Oh man, there is so, so much pain here. Random example - if GOOGLE_GENAI_USE_VERTEXAI=true in your environment, woe betide you if you're trying to use gemini cli with an API key. Error messages don't match up with actual problems, you'll be told to log in using the cli auth for google, then you'll be told your API keys have no access.. It's just a huge mess. I still don't really know if I'm using a vertex API key or a non-vertex one, and I don't want to touch anything since I somehow got things running..

      Anyway vai com dios, I know that there's a fundamental level of complexity deploying at google, and deploying globally, but it's just really hard compared to some competitors. Sadly, because the gemini series is excellent!

    • Hi, is your team planning on adding a spending cap? Last I tried, there was no reasonable way to do this. It keeps me away from your platform because runaway inference is a real risk for any app that calls LLMs programatically.

    • The fact that your team is worrying about billing is...worrying. You guys should just be focused on the product (which I love, thanks!)

      Google has serious fragmentation problems, and really it seems like someone else with high rank should be enforcing (and have a team dedicated to) a centralized frictionless billing system for customers to use.

    • This is nice that you know about the issue and are working on it. I really appreciate all the new "Get api key" buttons across google ai products that already makes it much easier than setting up a cloud project and getting credentials json files.

      But I do think it's a general problem with Google products that the solution is always to build a new one. There are already like 8 ways to use and pay for Google AI and that adds to the complexity of getting set up, so adding a new simpler better option might make that all worse instead of better

    • Maybe if the sign up process encouraged people to send videos (screen-side and user-side could be useful also), of their sign-up and usage experience, the teams responsible for user experience could make some real progress. I guess the question is, who cares, or who is responsible in the organization?

    • Can we get free Nano Banana in AI studio at least in super low resolution? For app building and testing purposes it will be fine and cheap enough for you to make it possible?

    • Hopefully the mobile version of AI Studio gets some improvement. There are some pretty awful UI bugs that make it really difficult to use in a mobile first manner.

      Though I still managed to vibe code an app using nanobanana. Now I just need to sort API billing with it so I can actually use my app.

    • Dude. Let me give you my money. This isn’t rocket science. I don’t want anything to do with Google Cloud or Google Workspace or w/e it’s called now. Let me just subscribe to Gemini or Nano straight up.

      This should be like 2 clicks.

    • I had the same reaction as them many months ago, the Google Cloud and Vertex AI stuff namespacing is a too messy. The different paths people might take to learning and trying to use the good new models needs properly mapping out and fixing so that the UX makes sense and actually works as they expect.

    • I had pretty much written off ever my credit card to Google, but a better billing experience and hard billing caps might change that.

  • Google APIs in general are hilariously hard to adopt. With any other service on the planet, you go to a platform page, grab an api key and you’re good to go.

    Want to use Google’s gmail, maps, calendar or gemini api? Create a cloud account, create an app, enable the gmail service, create an oauth app, download a json file. Cmon now…

    • Yeah, I'm not a dev and not using AI at all but had a need to create oauth keys and some APIs for some project... sometimes it works sometimes it doesnt and it's so complicated...but got it working in the end, thos it stops working after some time, it was like, Google, really?

  • If it's just the API you're interested in, Fal.ai has put Nano-Banana-Pro up for both generative and editing. A great deal less annoying to sign up for them since they're a pretty generalized provider of lots of AI related models.

    • In general a better option, in the early days of AI video I tried to generate a video of a golden retriever using Google's AI Studio. It generated 4 in the highest quality and charged me 36 bucks. Not a crazy amount but definitely an unwelcome suprise.

      Fal.ai is pay as you go and has the cost right upfront.

    • Is there a model on Fal.ai that would make it easy to sharpen blurry video footage? I have found some websites, but apparently they are mostly scammy.

    • There's the solution right there. Google is still growing its AI "sea legs". They've turned the ship around on a dime and things are still a little janky. Truly a "startup mode" pivot.

      While we're on this subject of "Google has been stomping around like Godzilla", this is a nice place to state that I think the tide of AI is turning and the new battle lines are starting to appear. Google looks like it's going to lay waste to OpenAI and Anthropic and claim most of the market for itself. These companies do not have the cash flow and will have to train and build their asses off to keep up with where Google already is.

      gpt-image-1 is 1/1000th of Nano Banana Pro and takes 80 seconds to generate outputs.

      Two years ago Google looked weak. Now I really want to move a lot of my investments over to Google stock.

      How are we feeling about Google putting everyone out of work and owning the future? It's starting to feel that way to me.

      (FWIW, I really don't like how much power this one company has and how much of a monopoly it already was and is becoming.)

  • 100% this. I am using the pro/max plans on both claude and openai. Would love to experiment with gemini but paying is next to impossible. Why do i need the risk of a full blown gcp project just to test gemini. No thx.

  • So much this. The entire experience around using Google's AI API's is a complete shit-show. I was (stubborn|obstinate|stupid|whatever) enough to keep dicking around until I actually got some stuff working (a few weeks ago) but I still feel dirty from the whole process. And I still don't know what I'm using (Gemini? AI Studio? Vertex? GCP? Other??) or how all of this crap relates.

    And FSM forbid I have another time when my debit card number gets compromised and I have to try changing it with Google. That was even MORE painful than just trying to get things working in the first place. WTF am I editing, my GCP account or my Google account? Are those two different things? Yes? No? Sort of? But they're connected, somehow... right? I mean, I disable my card in one place, but find that billing is still trying to go to it anyway. And then I find another place on another Google page that mentions that card, but when I try to disable it I get some opaque error about "can't disable card because card is already in use. Disable card first" or whatever.

    I can't even... I mean, shit. It's hard to imagine creating an experience that is that bad even if you were trying to do so.

    Let me just say, I won't be recommending Google's AI API's, or GCP, or Vertex, or any of this stuff to anybody, anytime soon. I don't care how good their models are.

    At least chatting with Gemini at gemini.google.com works. So far that's about the only thing AI related from Google I've seen that doesn't seem like a complete cluster-f%@k.

  • Ha, I have been steeling myself for a long chat with Claude about “how the F to get AI Studio up and working.” With paying being one of the hardest parts.

    Without a doubt one essential ingredient will be, “you need a Google Project to do that.” Oh, and it will also definitely require me to Manage My Google Account.

  • There is an entire business opportunity in just building better user and developer frontends to Google's AI products. It's so incredibly frustrating.

  • As a small advertiser, it can be surprisingly hard to give them money sometimes. (Trying to advertise an Airbnb.)

  • It's amazing that the "hard problems" are turning out to be "not creating a completely broken user experience".

    Is that going to need AGI? Or maybe it will always be out of reach of our silicon overlords and require human input.

  • >I decided to link my card to their AI studio.

    A lot of us did this in the last 2 days. Gemini3 first and now this.

  • Oh my, you should have tried to integrate with Google Prism. That was a madness! Nano Banana was just a little tricky to set up in comparison!

  • You can use it also in Gemini.

    • It wasn't there when I first went to Gemini after the announcement, but upon revisiting it gave me the prompt to try Nano Banana Pro. It failed at my niche (rare palm trees).

      Incredible technology, don't get me wrong, but still shocked at the cumbersome payment interface and annoyed that enabling Drive is the only way to save.

    • I hate that they kinda try to hide the model version. Like if you click the dropdown in the chat box, you can see that "Thinking" means 3 Pro. When you select the "Create images" tool, it doesn't tell you it's using Nano Banana Pro until it actually starts generating the image.

      Tell me the model it's using. It's as if Google is trying to unburden me with the knowledge of what model does what but it's just making things more confusing.

      Oh, and setting up AI Studio is a mess. First I have to create a project. Then an API key. Then I have to link the API key to the project. Then I have to link the project to the chat session... Come on, Google.

  • How long till ai studio is in the graveyard i wonder? For real google has some of the most amazing tech but jfc do they suck at making a product.

    The only way i use google is via an api key which billing for is arcane to be charitable. How can billions not crack the problem of quickly accepting cash from customers? Surely their ads platform does this?

Alright results are in! I've re-run all my editing based adherence related prompts through Nano Banana Pro. NB Pro managed to successfully pass SHRDLU, the M&M Van Halen test (as verified independently by Simon), and the Scorpio street test - all of which the original NB failed.

  Model results
  1. Nano Banana Pro: 10 / 12
  2. Seedream4: 9 / 12
  3. Nano Banana: 7 / 12
  4. Qwen Image Edit: 6 / 12

If you just want to see how NB and NB Pro compare against each other:

https://genai-showdown.specr.net/image-editing?models=nb,nbp

  • Please consider changing pass/fail to an integer score out of maybe 5. This test is becoming more and more misleading as your apparent desire to give due credit conflicts with quality improvements over already ok-ish models. For example, on the great wave Gemini 3’s excellent rendition gets no additional credit over Qwen technically not failing if one is generous, and on cards, there’s actually no score distinction between results that one could or could not use.

  • I think Nano banana pro’s answer to the giraffe edit is far superior to the Seedream response, but you passed Seedream and failed NB pro.

    Maybe that one is just not a good test?

    • I thought so too at first, but zoom in to where the neck joins the head. What looks like the head’s shadow from a distance is actually a hard seam between thick neck and thin neck, with much of the apparent shadow actually a cutout showing the background.

      Looks like the Seedream result here has been changed to fail, which I’d agree with, too. Pose change complaints aside, I think that neck is actually the same length were it held straight.

    • I agree, it seems like Seedream has the neck at same length as Nano Banana but also made the giraffe crouch down, making a major modification to the overall picture.

    • yeah i agree, the prompt is to "shorten the giraffe's neck length", not to bent it. i feel like the Gemini 3 produces better result on that one

  • I think Nano Banana Pro should have passed your giraffe test. It's not a great result but it is exactly what you asked for. It's no worse than Seedream's result imo.

    • Yeah I think that's a fair critique. It kind of looks like a bad cut-and-replace job (if you zoom in you can even see part of the neck is missing). I might give it some more attempts to see if it can do a better job.

      I agree that Seedream could definitely be called out as a fail since it might just be a trick of perspective.

      3 replies →

    • I agree. From where I'm sitting, Seedream just bent the neck while Nano Banana Pro actually shortened the neck.

  • The pisa tower test is really interesting. Many of this prompt have stricter criteria with implicit knowledge and some models impressively pass it. Yet for something as obvious as straightening a slanted object is hard even for latest models.

    • I suspect there'd be no problem rotating a different object. But this tower is EXTREMELY represented in the training data. It's almost an immutable law of physics that Towers in Pisa are Leaning.

    • It's an admittedly obscure reference to a cheating technique used in the Star Wars card game sabacc, which allows a player to surreptitiously switch out a card. I’m pretty sure I picked it up from one of Timothy Zahn's Thrawn books when I was a kid.

        Nano Banana Pro: 9 / 12
        Nano Banana: 8 / 12
      

      It's worth mentioning that even though it only scored slightly better than the original NB, many of the images are significantly better looking.

      https://genai-showdown.specr.net?models=nb,nbp

      3 replies →

    • Definitely! Even though NB's predominant use case seems to be editing, it's still producing surprisingly decent text-to-image results. Imagen4 currently still comes out ahead in terms of image fidelity, but I think NB Pro will close the gap even further.

      I'll try to have the generative comparisons for NB Pro up later this afternoon once I catch my breath.

  • Seedream generally looks like low quality outputs and it doesn’t seem like you’re assigning points for quality. This is only marginally helpful.

    • That's because, for the most part, I'm not:

      "A comparison of various SOTA generative image models on specific prompts and challenges with a strong emphasis placed on adherence."

      Adherence is the more interesting problem, in my opinion, because quality issues can be ameliorated through the use of upscalers, refiner models, LoRAs, and similar tools. Furthermore, there are already a thousand existing benchmarks obsessed with visual fidelity.

I...worked on the detailed Nano Banana prompt engineering analysis for months (https://github.com/minimaxir/gemimg) without pushing a new version by passing:

    g = GemImg(model="gemini-3-pro-image-preview")

I'll add the new output resolutions and other features ASAP. However, looking at the pricing (https://ai.google.dev/gemini-api/docs/pricing#standard_1), I'm definitely not changing the default model to Pro as $0.13 per 1k/2k output will make it a tougher sell.

EDIT: Something interesting in the docs: https://ai.google.dev/gemini-api/docs/image-generation#think...

> The model generates up to two interim images to test composition and logic. The last image within Thinking is also the final rendered image.

Maybe that's partially why the cost is higher: it's hard to tell if intermediate images are billed in addition to the output. However, this could cause an issue with the base gemimg and have it return an intermediate image instead of the final image depending on how the output is constructed, so will need to double-check.

  • >> - Put a strawberry in the left eye socket. >>- Put a blackberry in the right eye socket.

    >> All five of the edits are implemented correctly

    This is a GREAT example of the (not so) subtle mistakes AI will make in image generation, or code creation, or your future knee surgery. The model placed the specified items in the eye sockets based on the viewers left/right; when we talk relative in this scenario we usually (always?) mean from the perspective of the target or "owner". Doctors make this mistake too (they typically mark the correct side with a sharpie while the patient is still alert) but I'd be more concerned if we're "outsourcing" decision making without adequate oversight.

    • > when we talk relative in this scenario we usually (always?) mean from the perspective of the target or "owner".

      I dunno... I feel pretty confident 99% percent of people would do the same thing, and put the strawberry in the eye socket to our left, the viewer's.

      You really have to be trained explicitly to put yourself in the subject's shoes, and very few people are. To me, the model is correctly following the instructions most people will mean.

      And it's not even incorrect. "The left x" is linguistically ambiguous. If you say "the left flower", it's obviously the flower to our left. So when you say "the left eye socket", the eye socket to our left is a valid interpretation. If they had said their or its left eye socket, then it's more arguable that it must be from the subject's side. But that's not the case in this example.

    • There's a classic well-illustrated book, _How to Keep Your Volkswagen Alive_, which spends a whole illustrated page at the beginning building up a reference frame for working on the vehicle. Up is sky, down is ground, front is always vehicle's front, left is always vehicle's left.

      Sounds a bit silly to write it out, but the diagram did a great job removing ambiguity when you expect someone to be laying on the ground in a tight place looking backwards, upside down.

      Also feels important to note that in the theatre, there is stage-right and stage-left, jargon to disambiguate even though the jargon expects you to know the meaning to understand it.

    • Right, that's why one should use "put a strawberry in the portside eye socket" and "put a strawberry in the starboard side socket"

    • That was a big problem when I was toying around the original Nano Banana. I always prompted the perspective of the (imaginary) camera, and yet NB often interpreted that as that of the target, giving no way to select the opposite side. Since the selected side is generally closer to the camera, my usual workaround is to force the side far from the camera. And yet that was not perfect.

    • I don't know if that's so much a mistake as it is ambiguity though? To me, using the viewer's perspective in this case seems totally reasonable.

      Does it still use the viewer's perspective if the prompt specifies "Put a strawberry in the _patient's left eye_"? If it does, then you're onto something. Otherwise I completely disagree with this.

  • Minor clarification, the cost for every input image is $0.0011, not $0.06.

    • I was going off the footnote of "Image input is set at 560 tokens or $0.067 per image" but 560 * 2 / 1_000_000 is indeed $0.0011 so I have no idea where the $0.067 came from. Fixed, and this is why I typically don't read docs without coffee.

  • I just pushed gemimg 0.3.2 which adds image_size support for Nano Banana Pro, and I ran a few tests on some of the images in the blog. In my testing, Nano Banana Pro correctly handled most of the image generation errors noted in my blog post: https://x.com/minimaxir/status/1991580127587921971

    - Fibonacci magnets: code is correctly indented and the syntax highlighting atleast tries giving variables, numbers, and keywords different colors.

    - Make me a Studio Ghibli: actually does style transfer correctly, and does it better than ChatGPT ever did.

    - Rendering a webpage from HTML: near-perfect recreation of the HTML, including text layout and element sizing.

    That said, there may be regressions where even with prompt engineering, the generated images which are more photorealistic look too good and land back into the uncanny valley. I haven't decided if I'm going to write a follow up blog post yet.

    The system prompt hacking trick doesn't work with Nano Banana Pro unfortunately.

  • Your wrapper is awesome and still relevant.

    > "I...worked on the detailed Nano Banana prompt engineering analysis for months"

    Early in four decades of tech innovation I wasted time layering on fixes for clear deficiencies in a snowballing trend's tech offerings. If it's a big enough trend to have well funded competitors, just wait. The concern is likely not unique, and will likely be solved tomorrow.

    I realized it's better to learn adaptive/defensive techniques, giving your product resilience to change. Your goal is that when surfing the change waves you can pick a point you like between rock solid and cutting edge and surf there safely.

    Invest that "remediate their thing" time in "change resilience" instead – pays dividends from then on. It can be argued your tool is in this camp!

This combined the synth generation of a person and made the puppet dance. Quite impressive

  • > The model generates up to two interim images to test composition and logic. The last image within Thinking is also the final rendered image.

    I've been using a bespoke Generative Model -> VLM Validator -> LLM Prompt Modifier REPL as part of my benchmarks for a while now so I'd be curious to see how this stacks up. From some preliminary testing (9 pointed star, 5 leaf clover, etc) - NB Pro seems slightly better than NB though it still seems to get them wrong. It's hard to tell what's happening under the covers.

  • this is pretty cool! have you found success with image editing in nano banana - i mean photoshop-like stuff. from your article i seem to wonder if nano banana is good for editing versus generating new images.

    • That IS the use-case for Nano Banana (as opposed to pure generative like Imagen4).

      In my benchmarks, Nano-Banana scores a 7 out of 12. Seedream4 managed to outpace it, but Seedream can also introduce slight tone mapping variations. NB is the gold standard for highly localized edits.

    I did manage to get one image of a piano keyboard where the black keys were correct, but not consistently.

    • I've tried similar stuff such as: "Show a piano with an outstretched hand playing a Emaj triad on the E, G#, and B keys".

      https://imgur.com/ogPnHcO

      Even generating a standard piano with 7 full octaves that are consistent is pretty hard. If you ask it to invert the colors of the naturals and sharps/flats you'll completely break them.

  • It even worked really well at creating an infographic for one of my quirkier projects which doesn't have that much information online (other than its repo).

    "An infographic explaining how player.html works (from the player.html project on Github). https://github.com/pseudosavant/player.html"

    And then it made one formatted for social: "Change it to be an infographic formatted to fit on Instagram as a 1:1 square image."

  • I’ve been really excited for you infographic generation. Previous models from Google and openAI had very low detail/resolution for these things.

    I’ve found in general that the first generation may not be accurate but a few rolls of the dice and you should have enough to pick a style and format that works, which you can iterate on.

  • Game changer for architecture diagrams.

    • I'm finding it bad at instruction following for architectural specs (physical not software), where you tell it what goes where, and it ignores you and does some average-ish thing it's seen before. It looks visually appealing though.

  • Did you check if the SynthID works when you edit the photos with filters like GrayScale?

  • It would be great if Google could make SynthID openly available so OpenAI etc could also implement it. Then websites like Facebook, or even local browsers, could implement an "AI warning".

I used the new Nano Banana Pro just now, indirectly. I was brainstorming with Gemini 3 Thinking mode (now the default best thinking option on my iPadOS Gemini app) over a system design for an open source project that I hope to put a lot of effort into next year and then I asked for a detailed system level diagram.

The results were very good because the diagram reflected what I had specified during chat.

I probably sounded like an idiot when Gemini 3 was released: I have been a paid ‘AI practitioner’ since 1982, lived through multiple AI winters, but I wrote this week that Gemini 3 meets my personal expectations for AGI for the non-physical (digital) world.

Something I find weird about AI image generation models is that even though they no longer produce weird "artifacts" that give away that the fact that it was AI generated, you can still recognize that it's AI due to stylistic choices.

Not all examples they gave were like this. The example they gave of the word "Typography" would have fooled me as human-made. The infographics stood out though. I would have immediately noticed that the String of Turtles infographic was AI generated because of the stylistic choices. Same for the guide on how to make chai. I would be "suspicious" of the example they gave of the weather forecast but wouldn't immediately flag at as AI generated.

Similar note, earlier I was able to tell if something was AI generated right off the bat by noticing that it had a "Deviant Art" quality to it. My immediate guess is that certain sources of training data are over-represented.

  • We are just very sharp when it comes to seeing small differences in images.

    I'm reminded of when the air force decided to create a pilot seat that worked for everyone. They took the average body dimensions of all their recruits and designed a seat to fit the average. It turned out, the seat fit none of their recruits. [1]

    I think AI image generation is a lot like this. When you train on all images, you get to this weird sort of average space. AI images look like that, and we recognize it immediately. You can prompt or fine tune image models to get away from this, though -- the features are there it's a matter of getting them out. Lots of people trying stuff like this: https://www.reddit.com/r/StableDiffusion/comments/1euqwhr/re..., the results are nearly impossible to distinguish from real images.

    [1] https://www.thestar.com/news/insight/when-u-s-air-force-disc...

    • What determines which “average” AI models latch onto? At a pixel level, the average of every image is a grayish rectangle; that's obviously not what we mean and AI does not produce that. At a slightly higher level, the average of every image is the average of every subject every photographed or drawn (human, tree, house, plate of food, ...) in concept space; but AI still doesn't generate a human with branches or a house with spaghetti on it. At a still higher level there are things we recognize as sensible scenes, e.g., barista pouring a cup of coffee, anime scene of a guy fighting a robot, watercolor of a boat on a lake, which AI still does not (by default) average into, say, an equal parts watercolor/anime/photorealistic image of a barista fighting a robot on a boat while pouring a cup of coffee.

      But it is undeniable that AI images do have an “average” feel to them. What causes this? What is the space over which AI is taking an average to produce its output? One possible answer is that a finite model size means that the model can only explore image space with a limited resolution, and as models get bigger/better they can average over a smaller and smaller portion of this space, but it is always limited.

      But that raises the question of why models don't just naturally land on a point in image space. Is this just a limitation of training, which punishes big failures more strongly than it rewards perfection? Or is there something else at play here that's preventing models from landing directly on a “real” image?

  • We can also pick up hints on discordant production value. This is quite noticeable on websites such as Amazon/Alibaba/Etsy/Ebay/etc where there's a lot of scam listings that use AI images for cheap or basic items.

    So even though the image shown doesn't present obvious flaws, the fact that the image is high quality is the tell-tale sign of being AI generated.

    This also isn't something that can be easily fixed - even if we produce convincing low production value imagery using AI, then the scam listing doesn't achieve its goal because it looks like junky crap.

  • I think it's because they're all trained on the same data (everything they could possibly scrape from the open web). The models tend to learn some kind of distribution of what is most likely for a given prompt. It tends to produce things that are very average looking, very "likely", but as a result also predictable and unoriginal.

    If you want something that looks original, you have to come up with a more original prompt. Or we have to find a way to train these models to sample things that are less likely from their distribution? Find a way to mathematically describe what it means to be original.

    • An more original prompt wont fix things. Modern base models want to eliminate everything that puts their creators at risk, which is anything that is clearly made by someone else, more or less accurately reproducible. If you avoid decent representation of any artist style, or anything/anyone that is likely to go to court, you wont get the chance of an creative synthesis either.

  • It still has some artifacts more often than not, they are a lot subtler in nature but they still come out, whether it's texture, proportion, lighting, or perspective. Now some things are easier to fix on second pass edits, some are not. I guess it's why they consider image editing to be the next challenge.

  • The problem is how they are fine tuned with human feedbacks that are not opinionated, so they produce some "average taste" that is very recognizable. Early models didn't have this issue, it's a paradox... Lower quality / broken images but often more interesting. Krea & Black Forest did a blog post about that some time ago.

    • Oh yeah, funny enough even though I’m a bit of an AI art hater I actually thought very early Midjourney looked good because of all had an impressionistic, dreamy quality.

    • I wonder if we'll get to the point where we train different personalities into an image model that we can bring out in the prompt and these personalities have distinct art/picture styles they produce.

  • I don't think it's solely an data issue. Flux models for example are quite stylized, very notable with photorealism. But I think it was an deliberate choice to to have outputs that are absent of likeness and distinct style. I think it's an side effect that it washes away fine details and creates outputs feel artificial. The problem is that closed models can't be fixed easily, while models like flux or even older architectures can add back details and style with fine tuning and LoRas.

  • It's a bit odd to say, but another big clue identifying something as AI-generated is that it simply looks "too good" for what it is being used for. If I see a little info graphic demonstrating something relatively mundane, and it has nice 3D rendered characters or graphical elements, at this point it's basically guaranteed to be AI, because you just sort of intuitively know when something would've justified the human labor necessary to produce that.

    • Funny enough that had crossed my mind with the woodchuck example, because at a glance I can't see any weird artifacts, but I felt confident I could tell it was AI generated immediately if I saw it in the wild, and I couldn't really explain why. My immediate guess was "well, who the hell would actually bother to make something like this?"

    • It's not odd to say. It was one of the first telling signs to identify AI artists[0] on Twitter: overly detailed backgrounds.

      Of course now a lot of them have learned the lesson and it's much harder to tell.

      [0]: I know, I know...

  • Maybe the AI feeling is illusion because you already know it's AI-generated, just confirmation bias. Like wine tastes better after knowing it's expensive. In real world AI-generated images have passed Turing test. Only by double blind test do you can be really sure.

The interesting tidbit here is SynthID. While a good first step, it doesn't solve the problem of AI generated content NOT having any kind of watermark. So we can prove that something WITH the ID is AI generated but we can't prove that something without one ISN'T AI generated.

Like it would be nice if all photo and video generated by the big players would have some kind of standardized identifier on them - but now you're left with the bajillion other "grey market" models that won't give a damn about that.

  • Some days it feels like I'm the only hacker left who doesn't want government mandated watermarking in creative tools. Were politicians 20 years ago as overreative they'd have demanded Photoshop leave a trace on anything it edited. The amount of moral panic is off the charts. It's still a computer, and we still shouldn't trust everything we see. The fundamentals haven't changed.

    • > It's still a computer, and we still shouldn't trust everything we see. The fundamentals haven't changed.

      I think that by now it should be crystal clear to everyone that it matters a lot the sheer scale a new technology permits for $nefarious_intent.

      Knives (under a certain size) are not regulated. Guns are regulated in most countries. Atomic bombs are definitely regulated. They can all kill people if used badly, though.

      When a photo was faked/composed with old tech, it was relatively easy to spot. With photoshop, it became more complicated to spot it but at the same time it wasn't easy to mass-produce altered images. Large models are changing the rules here as well.

    • I suspect watermarking ends up being a net negative, as people learn to trust that lack of a watermark indicates authenticity. Propaganda won’t have the watermark.

    • Easy to say until it impacts you in a bad way:

      > “My wife and I have been together for over 30 years, and she has my voice everywhere,” Schlegel said. “She could easily clone my voice on free or inexpensive software to create a threatening message that sounds like it’s from me and walk into any courthouse around the country with that recording.”

      At the moment, the only alternative is courts simply never accept photo/video/audio as evidence. I know if I were a juror I wouldn't.

      At the same time, yeah, watermarks won't work. Sure, Google can add a watermark/fingerprint that is impossible to remove, but there will be tools that won't put such watermarks/fingerprints.

  • I'm sure Apple will roll something out in the coming years. Now that just anyone can easily AI themselves into a picture in front of the Eiffel tower, they'll want a feature that will let their users prove that they _really_ took that photo in front of the Eiffel tower (since to a lot of people sharing that you're on a Paris vacation is the point, more than the particular photo).

    I bet it will be called "Real Photos" or something like that, and the pictures will be signed by the camera hardware. Then iMessage will put a special border around it or something, so that when people share the photos with other Apple users they can prove that it was a real photo taken with their phone's camera.

    • This exists, the standard is called C2PA, Google added support for it in the Pixel 10. I was surprised and disappointed that Apple didn’t add support for it in the most recent iPhone! A few physical cameras are starting to support it too (https://yawnbox.eu/blog/c2pa-camera/)

      How "real" are iPhone photos? They're also computationally generated, not just the light that came through the lens.

      Even without any other post-processing, iPhones generate gibberish text when attempting to sharpen blurry images, they delete actual textures and replace them with smooth, smeared surfaces that look like a watercolor or oil paintings, and combine data from multiple frames to give dogs five legs.

  • The incentive for commercial providers to apply watermarks is so that they can safely route and classify generated content when it gets piped back in as training or reference data from the wild. That it's something that some users want is mostly secondary, although it is something they can earn some social credit for by advertising.

    You're right that there will existed generated content without these watermarks, but you can bet that all the commercial providers burning $$$$ on state of the art models will gradually coalesce around some means of widespread by-default/non-optional watermarking for content they let the public generate so that they can all avoid drowning in their own filth.

      There will always be a way to defeat anything, but I don't see why this won't work for like 90% of cases.

  • This is what the SynthID signature looks like on Nano Banana images https://www.reddit.com/r/nanobanana/comments/1o1tvbm/

    And if it can be seen like that, it should be removeable too. There are more examples in that thread.

    • > more examples in that thread

      Some supposition: A Fourier amplitude image should show that pattern as peaks at a certain angle/radius location. The exact location may be part of the identification scheme. Running peak finding on the Fourier image and then zeroing out the frequencies in the peak should remove the pattern. Modeling the shape of the peak would allow mimicking the application of a legit SynthID signature.

      If anyone tries/tried this already, I'd love to see the results.

  • It solves some problems! For example, if you want to run a camgirl website based on AI models and want to also prove that you're not exploiting real people

    • > It solves some problems! For example, if you want to run a camgirl website based on AI models and want to also prove that you're not exploiting real people

      So, you exploit real people, but run your images through a realtime AI video transformation model doing either a close-to-noop transformation or something like changing the background so that it can't be used to identify the actual location if people do figure out you are exploiting real people, and then you have your real exploitation watermarked as AI fakery.

      I don't think this is solving a problem, unless you mean a problem for the would-be exploiter.

    • Your use case doesn't even make sense. What customers are clamoring for that feature? I doubt any paying customer in the market for (that product) cares. If the law cares, the law has tools to inquire.

      All of this is trivially easy to circumvent ceremony.

      Google is doing this to deflect litigation and to preserve their brand in the face of negative press.

      They'll do this (1) as long as they're the market leader, (2) as long as there aren't dozens of other similar products - especially ones available as open source, (3) as long as the public is still freaked out / new to the idea anyone can make images and video of whatever, and (4) as long as the signing compute doesn't eat into the bottom line once everyone in the world has uniform access to the tech.

      The idea here is that {law enforcement, lawyers, journalists} find a deep fake {illegal, porn, libelous, controversial} image and goes to Google to ask who made it. That only works for so long, if at all. Once everyone can do this and the lookup hit rates (or even inquiries) are < 0.01%, it'll go away.

      It's really so you can tell journalists "we did our very best" so that they shut up and stop writing bad articles about "Google causing harm" and "Google enabling the bad guys".

      We're just in the awkward phase where everyone is freaking out that you can make images of Trump wearing a bikini, Tim Cook saying he hates Apple and loves Samsung, or the South Park kids deep faking each other into silly circumstances. In ten years, this will be normal for everyone.

      Writing the sentence "Dr. Phil eats a bagel" is no different than writing the prompt "Dr. Phil eats a bagel". The former has been easy to do for centuries and required the brain to do some work to visualize. Now we have tools that previsualize and get those ideas as pixels into the brain a little faster than ASCII/UTF-8 graphemes. At the end of the day, it's the same thing.

      And you'll recall that various forms of written text - and indeed, speech itself - have been illegal in various times, places, and jurisdictions throughout history. You didn't insult Caesar, you didn't blaspheme the medieval church, and you don't libel in America today.

  • You have to validate from the other direction. Let CCD sensors sign their outputs, and digital photo-editing produce a chain of custody with further signatures.

    Maybe zero knowledge proofs could provide anonymity, or a simple solution is to ship the same keys in every camera model, or let them use anonymous sim-style cards with N-month certificate validity. Not everyone needs to prove the veracity of their photos, but make it cheap enough and most people probably will by default.

  • Regardless of how you feel about this kind of steganography, it seems clear that outside of a courtroom, deepfakes still have the potential to do massive damage.

    Unless the watermark randomly replaces objects in the scene with bananas, these images/videos will still spread like wildfire on platforms like TikTok, where the average netizen's idea of due diligence is checking for a six‑fingered hand... at best.

  • I don't understand why there isn't an obvious, visible watermark at all. Yes, one could remove it but let's assume 95% of people don't bother removing the visible watermark. It would really help with seeing instantly when an image was AI generated.

  • It would be more productive for camera manufacturers to embed a per-device digital signature. Those care to prove their image is genuine could publish both pre and post processed images for transparency.

  • Reminder that even in the hypothetical world where every AI image is digitally watermarked, and all cameras have a TPM that writes a hash of every photo to the blockchain, there’s nothing to stop you from pointing that perfectly-verified camera at a screen showing your perfectly-watermarked AI image and taking a picture.

    Image verification has never been easy. People have been airbrushed out of and pasted into photos for over a century; AI just makes it easier and more accessible. Expecting a “click to verify” workflow is unreasonable as it has ever been; only media literacy and a bit of legwork can accomplish this task.

    • Competent digital watermarks usually survive the 'analog hole'. Screen-cam resistant watermarks have been in use since at least 2020, and if memory serves, back to 2010 when I first starting reading about them, but I don't recall what it was called back then.

    Take this a step further and it'll be a personal identifying watermark (only the company can decode). Home printers already do this to some degree.

  • This watermarking ceremony is useless.

    We will always have local models. Eventually the Chinese will release a Nano Banana equivalent as open source.

    • > We will always have local models.

      If watermarking becomes a legal mandate, it will inevitably include a prohibition on distributing (and using and maybe even possessing, but the distribution ban is the thing that will have the most impact, since it is the part that is most policable, and most people aren't going to be training their own models, except, of course, the most motivated bad actors) open models that do not include watermarking as a baked-in model feature. So, for most users, it'll be much less accessible (and, at the same time, it won't solve the problem.)

  • We need to be super careful with how legislation around this is passed and implemented. As it currently stands, I can totally see this as a backdoor to surveillance and government overreach.

    If social media platforms are required by law to categorize content as AI generated, this means they need to check with the public "AI generation" providers. And since there is no agreed upon (public) standard for imperceptible watermarks hashing that means the content (image, video, audio) in its entirety needs to be uploaded to the various providers to check if it's AI generated.

    Yes, it sounds crazy, but that's the plan; imagine every image you post on Facebook/X/Reddit/Whatsapp/whatever gets uploaded to Google / Microsoft / OpenAI / UnnamedGovernmentEntity / etc. to "check if it's AI". That's what the current law in Korea and the upcoming laws in California and EU (for August 2026) require :(

  • I don't believe that you can do this for photography. For AI-images, if the embedded data has enough information (model identification and random seed), one can prove that it was AI by recreating it on the fly and comparing. How do you prove that a photographic image was created by a CCD? If your AI-generated image were good enough to pass, then hacking hardware (or stealing some crypto key to sign it) would "prove" that it was a real photograph.

    Hell, it might even be possible for some arbitrary photographs to come up with an AI prompt that produces them or something similar enough to be indistinguishable to the human eye, opening up the possibility of "proving" something is fake even when it was actually real.

    What you want just can't work, not even from a theoretical or practical standpoint, let alone the other concerns mentioned in this thread.

  • It solves a real problem - if you have something sketchy, the big players can repudiate it, the authorities can more formally define the black market, and we can have a ‘war on deepfakes’ to further enable the authorities in their attempts to control the narratives.

  • Labelling open source models as "grey market" is a heck of a presumption

    • Every model is "grey market". They're all trained on data without complying with any licensing terms that may exist, be they proprietary or copyleft. Every major AI model is an instance of IP theft.

It's crazy how good these models are at text now. Remember when text was literally impossible? Now the models can diagetically render any text. It's so good now that it seems like a weird blip that it _wasn't_ possible before.

Not to mention all the other stuff.

  • I agree, it's improving by leaps. I'm still patiently awaiting for my niche use of creating new icons though, one that can match the existing curvature, weight, spacing, and balance. It seems AI is struggling in the overlap of visuals <-> code, or perhaps there's less business incentive to train on that front. I know the pelican on bicycle svg is getting better, but still really rough looking and hard to modify with prompt versus just spending some time upfront to do it yourself in an editor.

  • I wonder; do you think these LLMs now rather have text tools, or is this still straight out of the neural network? If its the latter, thats incredibly impressive.

I've had nano banana pro for a few weeks now, and it's the most impressive AI model I've ever seen

The inline verification of images following the prompt is awesome, and you can do some _amazing_ stuff with it.

It's probably not as fun anymore though (in the early access program, it doesn't have censoring!)

  • Genuinely believe that images are 99.5% solved now and unless you’re extremely keen eyed, you won’t be able to tell AI images from real images now

    • Eyebrows, eyelashes and skin texture are still a dead giveaway for AI generated portraits. Much harder to tell the difference with everything else.

  • I'd be curious about how well the inline verification works - an easy example is to have it generate a 9-pointed star, a classic example that many SOTA models have difficulties with.

    In the past, I've deliberately stuck a Vision-language model in a REPL with a loop running against generative models to try to have it verify/try again because of this exact issue.

    EDIT: Just tested it in Gemini - it either didn't use a VLM to actually look at the finished image or the VLM itself failed.

    Output:

      I have finished cross-referencing the image against the user's specific requests. The primary focus was on confirming that the number of points on the star precisely matched the requested nine. I observed a clear visual representation of a gold-colored star with the exact point count that the user specified, confirming a complete and precise match.
    
    

    Result:

      Bog standard star with *TEN POINTS*.

  • "Inline verification of images following the prompt is awesome, and you can do some _amazing_ stuff with it." - could you elaborate on this? sounds fascinating but I couldn't grok it via the blog post (like, it this synthid?)

    • It uses Gemini 3 inline with the reasoning to make sure it followed the instructions before giving you the output image

  • LLMs might be a dead end, but we're going to have amazing images, video, and 3D.

    To me the AI revolution is making visual media (and music) catch up with the text-based revolution we've had since the dawn of computing.

    Computers accelerated typing and text almost immediately, but we've had really crude tools for images, video, and 3D despite graphics and image processing algorithms.

    AI really pushes the envelope here.

    I think images/media alone could save AI from "the bubble" as these tools enable everyone to make incredible content if you put the work into it.

    Everyone now has the ingredients of Pixar and a music production studio in their hands. You just need to learn the tools and put the hours in and you can make chart-topping songs and Hollywood grade VFX. The models won't get you there by themselves, but using them in conjunction with other tools and understanding as to what makes good art - that can and will do it.

    Screw ChatGPT, Claude, Gemini, and the rest. This is the exciting part of AI.

    • Doesn’t seem like a dead end at all. Once we can apply LLMs to the physical world and its outputs control robot movements it’s essentially game over for 90% of the things humans do, AGI or not.

This is the first image model I’ve used that passed my piano test. It actually generated an image of a keyboard with the proper pattern of black keys repeated per octave – every other model I’ve tried this with since the first Dall-E has struggled to render more than a single octave, usually clumping groups of two black keys or grouping them four at a time. Very impressive grasp of recursive patterns.

  • If you ask it for anything outside of the standard 88 key set it falls short. For instance

    "Generate a piano, but have the left most key start at middle C, and the notes continue in the standard order up (D, E, F, G, ...) to the right most key"

    The above prompt will be wrong, seemingly every time. The model has no understanding of the keys or where they belong, and it is not able to intuit creating something within the actual confines of how piano notes are patterned.

    "Generate a piano but color every other D key red"

    This also wrong, every time, with seemingly random keys being colored.

    I would imagine that a keyboard is difficult to render (to some extent) but I also don't think its particularly interesting since it is a fully standardized object with millions of pictures from all angles in existence to learn from right?

  • Periodic motion (groups of repeating patterns) always tend to degrade at some point. Maintaining coherence over 88 keys is impressive.

I don't understand the excitement around generating and/or watching AI-produced videos. To me it's probably the single most uninteresting and boring thing related to AI that I can think of. What is the appeal?

  • Thoughts on photography when it first appeared:

    "Not by the taking of a picture of any specific object, but by the way in which any random object could be made to appear on the photographic plate. This was something of such unheard-of novelty that the photographer was delighted by each and every shot he took, and it awakened unknown and overwhelming emotions in him..."

  • Pretty sure Nano Banana only produces images.

    Nonetheless, ask it to “create an infographic on how Google works”. Do you not see any excitement in the result? I think it’s pretty impressive and has a lot of utility.

    • Until people ask it to make convincing misinformation. Pretty, professional looking graphs are already hard to resist.

  • As a general content I agree it's a bit off putting, but I find it a lot of fun when generating content among friends like internal jokes and educational content. I got my kid to drink some meds by generating an image of a hero telling him it's important to take.

SynthID seems interesting but in classic Google fashion, I haven't a clue on how to use it and the only button that exists is join a waitlist. Apparently it's been out since 2023? Also, does SynthID work only within gemini ecosystem? If so, is this the beginning of a slew of these products with no one standard way? i.e "Have you run that image through tool1, tool2, tool3, and tool4 before deciding this image is legit?"

edit: apparently people have been able to remove these watermarks with a high success rate so already this feels like a DOA product

    No, its not the beginning, multiple different watermarking standards, watermark checking systems, and, of course, published countermeasures of various effectiveness for most of them, have been around for a while.

I've only managed to get a few prompts to go through, if it takes longer than 30 seconds it seems to just time out. Image quality seems to vary wildly; the first image I tried looked really good but then I tried to refresh a few times and it kept getting worse.

  • Thanks - this worked for me (some errors, some success).

    Last week I was making a birthday card for my son with the old model. The new model is dramatically better - I'm asking for an image in comic book style, prompted with some images of him.

    With the previous model, the boy was descriptively similar (e.g. hair colour and style) but looked nothing like him. With this model it's recognisably him.

I guess the true endgame of AI products is naming them. We still have quite a way to go.

  • I was at a tech conference yesterday, and I asked someone if they had tried nano banana. They looked at me like I was crazy. These names aren't helping! (But honestly I love it, easier to remember than Gemini-2.whatever.

  • This has always been the hardest problem in computer science besides “Assume a lightweight J2EE distribution…”

  • There are only 2 hard problems in computer science: cache coherency, naming things and off by 1 errors...

  • Honestly I give Google credit for realizing that they had something that people were talking about and running with it instead of just calling it gemini-image-large-with-text-pro

    • They tried calling it gemini-2.5-whatever, but social media obsessed over the name "Nano Banana", which was just its codename that got teased on Twitter for a few weeks prior to launch.

      After launch, Google's public branding for the product was "Gemini" until Google just decided to lean in and fully adopt the vastly more popular "Nano Banana" label.

      The public named this product, not Google. Google's internal codename went virally popular and outstaged the official name.

      Branding matters for distribution. When you install yourself into the public consciousness with a name, you'd better use the name. It's free distribution. You own human wetware market share for free. You're alive in the minds of the public.

      Renaming things every human has brand recognition of, eg. HBO -> Max, is stupid. It doesn't matter if the name sucks. ChatGPT as a name sucks. But everyone in the world knows it.

      This will forever be Nano Banana unless they deprecate the product.

Does anyone know if this is predicting the entire image at once, or if it's breaking it into constituent steps i.e. "draw text in this font at this location" and then composing it from those "tools"? It would be really interesting if they've solved the garbled text problem within the constraint of predicting the entire image at once.

  • I strongly suspect it's the latter, though someone please chime in if I'm wrong.

    Even so, this is a real advancement. It's impressive to see existing techniques combined to meaningfully improve on SOTA image generation.

  • The previous nano banana was using composing tools. It was really obvious by some of the janky outputs it made. Not sure about this one, but presumably they built off it.

  • There still is some garbled text sometimes so it can't be the latter (try to get it to generate a map of 48 us states labeled - the ones that are too small to write on and need arrows were garbled (1 attempt))

  • I’m pretty sure, but no expert on the matter, that correct text rendering was solved by feeding in bitmaps of rasterized fonts as supplemental context to the image generation models.

I've tried to repaint the exterior of my house. More than 20 times with very detailed prompts. I even tried to optimize it with Claude. No matter what, every time it added one, two or three extra windows to the same wall.

  • I tried this in AI studio just now with nano banana.

    Results: https://imgur.com/a/9II0Aip

    The white house was the original (random photo from Google). The prompt was "What paint color would look nice? Paint the house."

    • > (random photo from Google)

      Careful with that kind of thing.

      Here, it mostly poisons your test, because that exact photo probably exists in the underlying training data and the trained network will be more or less optimized on working with it. It's really the same consideration you'd want to make when testing classifiers or other ML techs 10 years ago.

      Most people taking to a task like this will be using an original photo -- missing entirely from any training date, poorly framed, unevenly lit, etc -- and you need to be careful to capture as much of that as possible when trying to evaluate how a model will work in that kind of use case.

      The failure and stress points for AI tools are generally kind of alien and unfamiliar because the way they operate is totally different than the way a human operates, and if you're not especially attentive to their weird failure shapes and biases when you want to test them, or you'll easily get false positives (and false negatives) that lead you to misleading conclusions.

    • > The prompt was "What paint color would look nice? Paint the house."

      At some point, this is probably gonna result in you coming home to a painted house and a big bill, lol.

  • I also tried that in the past with poor results. I just tried it this morning with nano banana pro and it nailed it with a very short prompt: "Repaint the house white with black trim. Do not paint over brick."

  • I don't know what it is with Gemini (and even other models) but I swear they must be doing some kind of active load-dependant quanitization or a/b/c/d testing behind the scenes, because sometimes the model is stellar and hitting everything, and other times it's tripping all over itself.

    The most effective fix I have found is that when the model is acting dumb, just turn it off and come back in the few hours to a new chat and try again.

  • I have this problem selecting Pro, but if I use 2.5 Flash it does a great job at these things. I am not sure why Pro does not work as well.

Google needs to pace themselves. AI studio, Antigravity, Banana, Banana Pro, Grape Ultra, Gemini 3, etc. This information overload don't do them any good whatsoever.

  • Why? They're mostly different markets. Most people using Nano Banana Pro aren't using Antigravity.

    A cluster of launches reinforces the idea that Google is growing and leading in a bunch of areas.

    In other words, if it's having so many successes it feels like overload, that's an excellent narrative. It's not like it's going to prevent people from using the tools.

    • > A cluster of launches reinforces the idea that Google is growing and leading in a bunch of areas.

      What in the Gemini 3 powered astroturf bot is this?

      They probably just had an internal mandate to ship by end of year.

      > if it's having so many successes it feels like overload, that's an excellent narrative

      Yeah, if this is the best spin you've got I'm doubling down. Those teams were on the chopping block.

The rollout doesn't seem to have reached my userid yet. How successful are people at getting these things to actually produce useful images? I was trying recently with the (non-Pro) Nano Banana to see what the fuss was about. As a test case, I tried to get it to make a diagram of a zipper merge (in driving), using numbered arrows to indicate what the first, second, third, etc. cars should do.

I had trouble reliably getting it to...

* produce just two lanes of traffic

* have all the cars facing the same way—sometimes even within one lane they'd be facing in opposite directions.

* contain the construction within the blocked-off area. I think similarly it wouldn't understand which side was supposed to be blocked off. It'd also put the lane closure sign in lanes that were supposed to be open.

* have the cars be in proportion to the lane and road instead of two side-by-side within a lane.

* have the arrows go in the correct direction instead of veering into the shoulder or U-turning back into oncoming traffic

* use each number once, much less on the correct car

This is consistent with my understanding of how LLMs work, but I don't understand how you can "visualize real-time information like weather or sports" accurately with these failings.

Below is one of the prompts I tried to go from scratch to an image:

> You are an illustrator for a drivers' education handbook. You are an expert on US road signage and traffic laws. We need to prepare a diagram of a "zipper merge". It should clearly show what drivers are expected to do, without distracting elements.

> First, draw two lanes representing a single direction of travel from the bottom to the top of the image (not an entire two-way road), with a dotted white line dividing them. Make sure there's enough space for the several car-lengths approaching a construction site. Include only the illustration; no title or legend.

> Add the construction in the right lane only near the top (far side). It should have the correct signage for lane closure and merging to the left as drivers approach a demolished section. The left lane should be clear. The sign should be in the closed lane or right shoulder.

> Add cars in the unclosed sections of the road. Each car should be almost as wide as its lane.

> Add numbered arrows #1–#5 indicating the next cars to pass to the left of the "lane closed" sign. They should be in the direction the cars will move: from the bottom of the illustration to the top. One car should proceed straight in the left lane, then one should merge from the right to the left (indicate this with a curved arrow), another should proceed straight in the left, another should merge, and so on.

I did have a bit better luck starting from a simple image and adding an element to it with each prompt. But on the other hand, when I did that it wouldn't do as well at keeping space for things. And sometimes it just didn't make any changes to the image at all. A lot of dead ends.

I also tried sketching myself and having it change the illustration style. But it didn't do it completely. It turned some of my boxes into cars but not necessarily all of them. It drew a "proper" lane divider over my thin dotted line but still kept the original line. etc.

  • I'd try a some more if I were you. I saw an example of generated infographic that was greatly improved over anything I've seen an image generator do before. What you desire seems in the realm of possibility.

  • I think you tried using the wrong tool. Nano Banana is for editing, not generating (there's Imagen for that).

    • Imagen4 did no better. edit: example https://imgur.com/Dl8PWgm with a so-so result: four lanes, cars at least facing the same way, lane block looks good, weird extra division in the center, some numbers repeated, one arrow going straight into construction, one arrow going backwards

      edit: or Imagen4 Ultra. https://imgur.com/a/xr2ElXj cars facing opposite directions within a lane, 2-way (4 lanes total), double-ended arrows, confused disaster. pretty though.

2D animators can still feel safe about their job, I asked it to generate a sprite sheet animation by giving it the final frame of the animation (as a PNG file) and asking in detail what I wanted in the spritesheet, it just gave me mediocre results, I asked for 8 frames and it just repeated a bunch of poses just to reach that number instead of doing what a human would have done with the same request, meaning the in-betweens to make the animation smoother (AKA interpolations)

  • I’ve been using the same test since Dalle 2. No model has passed it yet.

    However, I don’t think 2D animators should feel too safe about their jobs. While these models are bad at creating sprite sheets in one go, there are ways you can use them to create pretty decent sprite sheets.

    For example, I’ve had good results by asking for one frame at a time. Also had good results by providing a sprite sheet of a character jumping, and then an image of a new character, and then asking for the same sprite sheet but with the new character.

  • With local models you can use control net, which is simply speaking, the model trying to adhere to a given wireframe/openpose. Which is more likely to give you an stable result. I have no experience with it, just wanted to point out that there is tooling that is more advanced.

  • the problem here is that text as the communication interface is not good for this. the model should be reasoning in the pose space (and generally in more geometric spaces), then interpolation and drawing is pretty easy. I think this will happen in some time.

  • At least until someone decides to fine-tune a general purpose model to the task of animation.

    • Yeah reading this I was thinking, we've got Qwen-Image-Edit which is an image model with an LLM backbone that takes well to finetuning.

      I'd be surprised if you can't get a 80%/20% result in a weekend, and even that probably saves you some time if you're just willing to pick best-of-n results

  • When I tried the same with video models a few months ago by extracting the frames, it was not working so well either.

    However, this should be solvable in the near future.

    I'm looking forward to making some 2D games.

  • However, if you ask it to generate eight or 10 frames of a sprite performing a particular action from scratch it gets it pretty spot on. In fact, you can drop them straight into an animator and have near production quality.

This is super awesome, but how in the world did they come up with a name "Nano Banana Pro"? It sounds like an April Fools joke.

  • It was an internal codename that leaked out and then despite trying to use a more corporate-friendly name that was terribly boring (Gemini 2.5 Flash Image), they got trolled into continuing to use nano banana because nobody would stop calling it that. Or that’s how the lore has been told so far

    I wouldn’t be surprised if Google shortens the name to NBP in the future, hoping everyone collectively forgets what NB stood for. And then proceeds to enshittify the name to something like Google NBP 18.5 Hangouts Image Editor

A houseplant with tiny turtles for leaves… very informative if under the influence of some substances.

It’s not a Hello World equivalent.

So much around generative ai seems to be around “look how unrealistic you can be for not-cheap! Ai - cocaine for your machine!!”

No wonder there’s very little uptake by businesses (MIT state of ai 2025, etc)

Gemini is all over the place for me. Nano Banana produces some great images. Today I asked Gemini to design a graphic based on the first sheet in a Google sheet. It produced a graphic with a summary of the data and a picture of a bed sheet. Nailed it.

Just last night I was using Gemini "Fast" to test its output for a unique image we would have used in some consumer research if there had been a good stock image back in the day. I have been testing this prompt since the early days of AI images. The improvement in quality has been pretty remarkable for the same prompt. Composition across this time has been consistent. What I initially thought was "good enough" now is... fantastic. Just so many little details got more life-like w/ each new generation. Funnily enough, our images must be 3:2 aspect ratio. I kept asking GFast to change its square Fast output to 3:2. It kept saying it would, but each image was square or nearly square. GFast in the end was very apologetic, and said it would alert about this issue. Today I read that GPro does aspect ratios. Tried the same prompt again burning up some "Thinking" credits, and got another fantastically life-like image in 3:2. We have a new project coming up. We have relied entirely on stock or in some cases custom shot images to date. Now, apart from the time needed to get the prompts right whilst meeting with the client, I cannot see how stock or custom images can compete. I mean the GPro images -- again which is very specific to an unusual prompt -- is just "Wow". Want to emphasize again -- we are looking for specific details that many would not. So the thoughts above are specific to this. Still, while many faults can be found with AI, Nano Banana is certainly proven itself to me.

edit: I was thinking about this, and am not sure I even saw Pro3 as my image option last night. Today it was clearly there.

Is SynthID actually running an AI classifier to decide whether an image is model-generated, or is it only checking for an embedded watermark? If it’s a classifier, the accuracy is questionable — generic “AI detection” tools tend to produce high false-positive rates. Also unclear whether it’s doing semantic anomaly checks (extra fingers, physics errors) or low-level pixel-signature analysis.

I tried the studio ghibli prompt on a photo my me and my wife in Japan and it was... not good. It looked more like a hand drawn sketch made with colored pencils, but none of the colors were correct. Everything was a weird shade of yellow/brown.

This has been an oddly difficult benchmark for Gemini's NB models. Googles images models have always been pretty bad at the studio ghibli prompt, but I'm shocked at how poorly it performs at this task still.

  • Could be they are specifically training against it. There was some controversy about "studio ghibli style". Similarly how in the early days of Stable Diffusion "Greg Rutkowski style" was a very popular prompt to get a specific look. These days modern Stable Diffusion based models like SD 3 or FLUX mostly removed references to specific artists from their datasets.

There's some really impressive things about this (the speed, the lack of typical AI image gen artifacts) but it also seems less creative than other models I've tried?

"mountain dew themed pokemon" is the first search prompt I always try with new image models and Nano Banna Pro just gave me a green pikachu.

Other models do a much better job of creating something new.

  • IMHO I'd rather them focus on strong literal prompt adherence so that more detailed prompts produce more accurate results.

    That way you can stick your choice of any number of LLM preprocessors in front of a generic prompt like "mountain dew themed pokemon" and push the responsibility of creating a more detailed prompt upstream.

    https://imgur.com/a/s5zfxS5

    Note: I'm not particularly impressed with either of the results - this is more a demonstration.

Generated images still contain JPEG artifacts all over them.

We are not doomed yet - can pretty much reliably spot RAW image vs AI-generated image by just zooming in

  • It's only a matter of time this will be fixed, also there probably already are custom LoRAs that can remove jpeg artifacts. So it's not a matter of if, only when.

    • I dont think so. You cant train away a compression artifact that comes from the model's core architecture, LoRAs can smooth or hide artifacts, but some detail will be inevitably lost. You can try to hide artifacts but not remove them without retraining the whole model on RAW sensor data.

Is there an "in joke" to this name that I am too old to get? Or it's just a whimsically random name?

With this model, I'm more worried about future online fraud. Will there still be authenticity?

I feel like I am going crazy or missed something simple but when I use the Gemini app and I ask it to edit a photo that I upload, 2.5 flash works really well but 2.5 pro or 3.0 pro do a very poor job. I uploaded an image of me and asked it to make me bald and flash did a great job of just changing me in the photo but 3.0 pro took me out of the photo completely and just created a headshot of a bald man that only sort of resembled me. Am I missing something or does paying for the pro version not give you anything over the 2.5 flash model?

  • The code name “nano banana” model is based on the Flash 2.5 foundation. Until today it was the “latest and greatest”.

First model I've seen that was consistently compositional, easily handling requests like

“Generate an image of an african elephant painted in the New England flag, doing a backflip in front of the russian federal assembly.”

OpenAI made the biggest step change towards compositionality in image generation when they started directly generating image tokens for decoders from foundation llms, and it worked very well (openais images were better in this regard than nano banana 1, but struggled with some OOD images like elephants doing backflips), but banana 2 nails this stuff in a way I haven't seen anywhere else

if video follows the same trends as images in terms of prompt adherence, that will be very valuable... and interesting

It’s interesting, I’m trying to use it to create a themed collage by providing a few images and it does that wonderfully, but in the process it is also hallucinating the images I use so I end up with weird distorted faces. Other tools can do this without issue, but something about faces in images this model just has to modify them every time. Ask it to remove background objects and the faces get distorted as well.

Using it for non-people involved images and it’s pretty good although I haven’t done much and it isn’t doing anything 2.5-flash wasn’t already doing in the same amount of requests.

This is really impressive. As a former designer, I'm equally excited that people will be able to generate images like this with a prompt, and sad that there will be much less incentive for people to explore design / "photoshopping" as a craft or a career.

At the end of the day, a tool is a tool, and the computer had the same effect on the creative industry when people started using them in place of illustrating by hand, typesetting by hand, etc. I don't want my personal bias to get in the way too much, but every nail that AI hammers into the creative industry's coffin is hard to witness.

  • I feel you. Infact, IMO, SWE1 level coding industry seems to be a couple years lagging on this aspect.

    The trouble is that learning fundamentals now is a large trough to go past, just the way grade 3-10 children learn their math fundamentals despite there being calculators. It's no longer "easy mode" in creative careers.

In my limited testing, at least in terms of maintaining consistency between input and output for Asian faces, it has even regressed.

Actually, Gemini 3 is about the same, and doesn't feel as good as Claude 4.5. I have a feeling it's been fine-tuned for a cool front-end marketing effect.

Furthermore, I really don't understand why AI Studio, now requiring me to use its own API for payment, still adds a watermark.

The naming is somehow getting worse. I swear we will soon see models that are named just with emojis.

Google is able to churn up SOTA models across the board. But still could not figure out the basic user journey. No Joke!

Slightly off topic, but how are people creating long videos like 30 second videos that I often see on Instagram? It I try to use Veo to make split videos, it simply cannot maintain the style or weird quirks get into the subsequent videos. Is there anything else that's the best video generation model currently other than Veo?

  • Longer videos without cuts are usually made from the first/last frame feature available in Veo 3.1 and other video models like Kling 2.5

The SynthID check for fishy photos is a step in the right direction, but without tighter integration into everyday tooling its not going to move the needle much. Like when I hold the power button on my Pixel 9, It would be great if it could identify synthetic images on the screen before I think to ask about it. For what its worth it would be great if the power button shortcut on Pixel did a lot more things.

  • You sort of can on Android, but it's a few steps:

    1. Trigger Circle to Search with long holding the home button/bar

    2. Select the image

    3. Navigate to About this image on the Google search top bar all the way to the right - check if it says "Made by Google AI" - which means it detected the SynthID watermark.

Wow! I was able to combine Nano Banana Pro and Veo 3.1 video generation in a single chat and it produced great results. https://chat.vlm.run/c/38b99710-560c-4967-839b-4578a4146956. Really cool model

  • Neat use-case, though the sword literally telescopically inverts itself at the beginning of the scene like a light saber where you would have expected it to be drawn from its scabbard.

    I'd be interested to see how Wan 2.2 First/Last frame handles those images though...

    • That is an interesting error actually. It happened because both orientations of the sword are visually plausible, but not abrupt transitions from one to the other; there needs to be physical continuity.

    • If you have concerns about spam, the right thing to do is to email the mods at hn@ycombinator.com with examples.

I tried the same prompt as one of the examples (https://i.imgur.com/iQTPJzz.png), in the two ways they say you can run it, via Google Gemini and Google AI Studio (I suppose they're different somehow?). The prompt was "Create an infographic that shows hot to make elaichi chai" and Google Gemini created a infographic (https://i.imgur.com/aXlRzTR.png), but it was all different from what the example showed. Google AI Studio instead created a interactive website, again with different directions: https://i.imgur.com/OjBKTkJ.png

There is not a single mention about accuracy, risks or anything else in the blogpost, just how awesome the thing is. It's clearly not meant to be reliable just yet, but not making this clear up front. Isn't this almost intentionally misleading people, something that should be illegal?

  • Whoever said there was a universal recipe for Elaichi Chai? It makes sense that there would be different recipes. If you are more stringent with the prompt and give it the proper context of what you want the steps to be, you'll arrive at that consistency.

I really hope Google reads these HN posts. They've had some big "product" wins but the pricing, packaging, and user system is a severe blocker to growth. If developers can't or won't figure it out -- how the heck are consumers?

  • And both their consumer apps are slow. You can replicate this yourself. Go to AI Studio, paste in 80K tokens of text, then type something on your keyboard, and see what happens. The Gemini web app is even worse somehow. A horrifically slow and buggy app. Not new problems either, barely any improvement on this over more than 1 year.

    • No issues here that I remember with the Gemini app on Android recently - half a year ago it was a slideshow with just a few conversations.

      They're improving, probably.

The funny part is that Google puts watermark on the generated graphics, because they are oh so not evil and socially responsible.

Unless you pay Google more, what is mentioned at the very bottom of this infomercial.

"Recognizing the need for a clean visual canvas for professional work, we will remove the visible watermark from images generated by Google AI Ultra subscribers and within the Google AI Studio developer tool."

BTW: anyone with the skills found in 1 min on the Internet can remove all of those ids, etc. (yes, as you might guess, the website is called remove synth id dot com...)

I was just playing with the non-pro version of this and it seems to add both a Gemini and Disney watermark. Presumably this was because I referenced beauty and the beast.

Anyone know if this is an hallucination or if they have some kind of deal with content owners to add branding?

> Generate better visuals with more accurate, legible text directly in the image in multiple languages

Assuming that this new model works as advertised, it's interesting to me that it took this long to get an image generation model that can reliably generate text. Why is text generation in images so hard?

  • Largely but not entirely a data problem; specifically poor captioning. High quality captioning makes such a big difference.

  • It’s not necessarily harder than other aspects. However:

    - It requires an AI that actually understands English, I.e. an LLM. Older, diffusion-only models were naturally terrible at that, because they weren’t trained on it.

    - It requires the AI to make no mistakes on image rendering, and that’s a high bar. Mistakes in image generation are so common we have memes about it, and for all that hands generally work fine now, the rest of the picture is full of mistakes you can’t tell are mistakes. Entirely impossible with text.

    Nano Banana Pro seems to somewhat reliably produce entire pictures without any mistakes at all.

  • As a complete layman, it seems obvious that it should be hard? Like, text is a type of graphic that needs to be coherent both in its detail and its large structure, and there’s a very small amount of variation that we don’t immediately notice as strange or flat out incorrect. That’s not true of most types of imagery.

"Sorry, I'm still learning to create images for you, so I can't do that yet. I can try to find one on the web though."

My experience with Nano Banana is to constantly get consistent image when dealing with muliple objects in a image, I mean creating consistent sequence etc.

We spent a lot of money trying but eventully gave up. If it is easier in Pro, then probably it stands a chance.

If Nano-Banana-pro with Veo 3.1 existed during my PhD, I would’ve finished a 6-year dissertation in a single year — it’s generating ideas today that used to take me 18 months just to convince people were possible.

Can anyone please explain me the invisible watermarking mentioned in the said promo?

What can nano-banana do that chatGPT made images can't? Or is it only better for image editing from what I can gather from these comments so far. I haven't used it so genuinely curious.

When my first thought was of an SBC, then a media AI cloud product was not high up on my guess list.

Interesting they didn’t post any benchmark results - lmarena/artificial analysis etc. I would’ve thought they’d be testing it behind the scenes the same way they did with Gemini 3.

Really interesting. Curious what the main design motivation behind this project was and what gaps it fills compared to existing tools?

Maybe I'm an obscure case, but I'm just not sure what I'd use an image generation model for.

For people that use them (regularly or not), what do you use them for?

  • Random examples:

    1) I have a tricep tendon injury and ChatGPT wants me to check my tricep reflex. I have no idea where on the elbow you're supposed to tap to trigger the reflex.

  • My most regular use-case is generating silly memes in group chats. If someone posts something meme-worthy or I come up with a creative response, image generation is good for one-off throwaway memes. A recent example was an "official license to opine on sociology", following someone arguing about credentialism.

    Recently I also started using image generation models to explore ideas for what changes to make in my paintings. Although generally I don't like the suggestions it makes, sometimes it provides me with creative ideas of techniques that are worth experimenting with.

    One way to approach thinking about it is that it's good for exploring permutations in an idea-space.

  • Nano Banana is more of an image editing model, which probably has more broad use cases for non-generative applications: interior decorating, architecture, picking wardrobes, etc.

    • Definitely, but don't sleep on its generative capacities either. You can give it a image and instruct it "Use the attached image purely as a stylistic reference" and then proceed to use it as a regular generative model.

    • Yeah... For some reason none of these are use cases in my day to day life. That said, I also don't open Photoshop very often. And maybe that's what this is meant to replace.

  • I'm creating a team T-shirt from a bunch of kids drawings. The model has synthesize a bunch of disparate drawings into a cohesive concept, incorporate the team's name in the appropriate color and font, and make it simple enough for a T-shirt.

  • porn is probably the a biggest one?

    but concept art, try-it-on for clothes or paint, stock art, etc

It's a funny juxtaposition to slap the "Pro" label on it which makes it sound more enterprisey but leave the name as Nano Banana.

I wouldn't trust any of the info in those images in the first carousel if I found them in the wild. It looks like AI image slop and I assume anyone who thinks those look good enough to share did not fact check any of the info and just prompted "make an image with a recipe for X"

  • Yeah, the weird yellow tint, the kerning/fonts etc still immediately gives it away.

    But I wouldn't mind being easily able to make infographics like these, I'd just like to supply the textual and factual content myself.

    • I would do the same. But the reason for that is because I’m terrible at drawing and digital art, so I would need some help with the graphics in an infographics anyways. I don’t really need help with writing text or typesetting the text. I feel like if I were better at creating art I would not want AI involved at all.

Nano Banana has been the only model I’ve really loved. As a small businesses who makes products, it’s been a game changer on the marketing side. Now when I’ve got something new I need to advertise in a hurry, I take a crappy pic and fix it in that. Don’t have a perfect model ready yet? That’s ok, I can just alter to look exactly like it will.

What used to cost money and involve wait time is now free and instant.

Everyone who worked on this is a traitor to the human race. Why do we need to make it impossible to make a living as an artist? Who thinks an endless tsunami of garbage “content” churned out by machines dropping the bottom out of all artistic disciplines is a good idea?

  • > Everyone who worked on this is a traitor to the human race.

    Have we felt this way for all other large scale advances in human history?

    • That's a question too generic. But yes, I guess? And people get Nobel prizes to point out that said advances have been causing the downfall of empires and nations.

  • To try to put a positive spin on it..

    It enables smaller teams to put out better quality products

    Imagine you're an artist that wants to create a video game but you suck at development. You could leverage AI to get good enough code and have amazing art

    On the other side someone who invested their entire skill tree in development can have amazing code and passable art

    The more I think about it the more it seems this AI revolution will hurt big companies the most. Most people have no hope of competing with a AAA game studio because they don't have the capital. Maybe this levels the playing field?

    • I am an artist. I have friends who like to code. I could leverage talking to my friends and saying "hey anyone wanna fool around and make some games". I could get Unreal and one of the 800 game templates available on their store for prices ranging from $0 to a few hundred bucks and start plopping my art in there and fiddling around. There's a bazillion art assets on there for the programmer with no art skills, too. And there's a section on the Unreal forums for people to say "hey I have this set of skills, who wants to make a game with me?".

      Or we could all just generate a bunch of completely unmaintanable code or some uncopyrightable art, sounds great.

  • I want to piggyback off what you’ve said, but for *additional* problems with this:

    To me, this is terrifying. Major use-cases presented on this page:

      * photo editing / post-processing
      * branding
      * infographics
    

    Photo editing and post-processing seems like the “least harmful” version of this. Doing moderate color-space tweaks or image extensions based on the images themselves seems like a “relatively not-evil” activity and will likely make a lot of artwork a bit nicer. The same technology will probably also be able to be used to upscale photos taken on Pixel cameras, which might be nice. MOSTLY. It’ll also call into question any super-duper-upscaled visuals when used as evidence for court and the “accuracy of photos as facts” - see the fake stuff Samsung did with the moon; but far, far more ubiquitous.

    However, Branding and Infographics are where I have concerns.

    Branding - it’s AI art, so it can’t be copyrighted, or are we just going to forget that?

    Infographics, though. We know that AI frequently hallucinates - and even hallucinates citations themselves, so … how can we generated infographics if they’re magicking into existence the stats used in the infographics themselves?!

    • Copyright is done, for better or worse. Up until very recently, many if not most HN'ers would have considered that a GOOD thing.

  • On the flip side, it can be good for the environment. Instead of spending tons of resources burning a car or doing a bunch of setup to get a shot, we can prompt it using relatively fewer energy resources.

  • Capitalism, at work. Wherever there is a cost, there will be attempts made at cost efficiency. Google understands that hiring designers or artists is expensive, and they want to offer a cheaper, more effective alternative so that they can capture the market.

    In a coffee shop this morning I saw a lady drawing tulips with a paper and pencil. It was beautiful, and I let her know... But as I walked away I felt sad that I don't feel that when browsing online anymore- because I remember how impressive it used to feel to see an epic render, or an oil painting, etc... I've been turned cynical.

  • (Shrug) If you expect to coast through an uneventful, unchallenging career, neither art nor technology are going to be great options for you. Learn to mine coal or something, I guess.

    Or... put your hands on the most amazing art tools since the Renaissance and go make something awesome.

    • No one using these tools will produce anything even a tenth as impressive as what was born out of the Renaissance, since their efforts were born of mastery, understanding, patience, a keen eye, and a love of nature and life. One who outsources their creativity and thinking to a machine will produce meaningless 'art' as empty as the shrinking contours of their mind as it withers away from non-use. Our world is not want for more quantity as we already drown in excess, and the quality and meaning inherit in masterful works of art born out of ones own hands will one day once again find their way to the center of our consciousness, as the world learns again that the value of art lies not solely in its appearances, but in its revelation of the human soul by means of Beauty, by which a human endeavors by great effort and skill to impart some aspect of their fleeting glimpse of the divine and sacred nature of being, by which our being here now as people of this earth and time consists of, which binds us all, now and through our history and our future.

Not gonna lie - this is pretty cool.

But ... it comes from Google. My goal is to eventually degoogle completely. I am not going to add any more dependency - I am way too annoyed at having to use the search engine (getting constantly worse though), google chrome (long story ...) and youtube.

I'll eventually find solutions to these.

I am extremely impressed by google this week.

I dont want to be annoying, its just a small piece of feedback, but srsly why is it so hard for google to have a simple onboarding experience for paying customers?

In the past I spoke about how my whole startup got taken offline for days because I "upgraded" to paying, and that was a decade ago. I mean it cant be hard, other companies dont have these issues!

Im sure it will be fixed in time, its just a bit bizarre. Maybe its just not enough time spent on updating legacy systems between departments or something.

Time to expand my creation catalog. Lets see what we can get of out this pro version. It seems this week is for big AI announcements from Google

really missed an opportunity to name it micro banana (or milli banana). Personally I can't wait for mega banana next year.

> Starting to roll out in the Gemini API and Google AI Studio

> Rolling out globally in the Gemini app

wanna be any more vague? is it out or not? where? when?

does it handle transparency yet?

  • This is a good question -- I've wanted transparency from image models for a while. One work around is to ask for a "green screen" and to key out the background but it doesn't always work very cleanly.

    • > One work around is to ask for a "green screen" and to key out the background but it doesn't always work very cleanly.

      I recently tried that and the model (not nano pro) added the green background as a gradient.

I’ve been struggling with infographics. That’s my main use case but every tool seems to bungle the text.

The visual quality of photorealistic images generated in the Gemini app seems terrible.

Like really ugly. The 1K output resolution isn't great, but on top of that it looks like a heavily compressed JPEG even at 100% viewing size.

Does AI Studio have the same issue? There at least I can see 2K and 4K output options.

One of the things I've always been curious about is how effective diffusion models can be for web and app design. They're generally trained on more organic photos, but post-training on SDXL and Flux have given me good results here in the past (with the exception of text).

It's been interesting seeing the results of Nano Banana Pro in this domain. Here are a few examples:

Prompt: "A travel planner for an elegant Swiss website for luxury hiking tours. An interactive map with trail difficulty and booking management. Should have a theme that is alpine green, granite grey, glacier white"

Flux output: https://fal.media/files/rabbit/uPiqDsARrFhUJV01XADLw_11cb4d2...

NBP output: https://v3b.fal.media/files/b/panda/h9auGbrvUkW4Zpav1CnBy.pn...

Prompt: "a landing page for a saas crypto website, purple gradient dark theme. Include multiple sections, including one for coin prices, and some graphs of value over time for coins, plus a footer"

Flux output: https://fal.media/files/elephant/zSirai8mvJxTM7uNfU8CJ_109b0...

NBP output: https://v3b.fal.media/files/b/rabbit/1f3jHbxo4BwU6nL1-w6RI.p...

Prompt: "product launch website for a development tool, dark background with aqua blue and neon gold highlights, gradients"

Flux output: https://fal.media/files/zebra/aXg29QaVRbXe391pPBmLQ_4bfa61cc...

NBP output: https://v3b.fal.media/files/b/lion/Rj48BxO2Hg2IoxRrnSs0r.png

---

Note that this is with a lora I built for flux specifically for website generation. Overall, nbp seems to have less creative / inspired outputs, but the text is FAR better than the fever dream Flux is producing. I'm really excited to see how this changes design. At the very least it proved it can get close to a production quality for output, now it's just about tuning it.

Anyone else think "Nano Banana" is an awful name? For some reason it really annoys me. It looks incredibly fancy, though.

What is up with these product names!? Antigravity? Nano Banana?

Not just are they making slop machines, they seem to be run by them.

I am too old for this shit.

Adobe's stock is down 50% from last year's peak. It's humbling and scary that entire industries with millions of jobs evaporate in a matter of few years.

  • There's 2 takes here: First take is the AI is replacing jobs by making existing workforce more efficient.

    The 2nd take is AI is costing companies so much money, that they need to cut workforce to pay for their AI investments.

    I'm inclined to think the latter is represents what's happening more than the former.

  • On the contrary, it's encouraging to know that maliciously greedy companies like Adobe are getting screwed for being so malicious and greedy :thumbsup:

    I had second thoughts about this comment, but if I stopped typing in the middle of it, I would've had to pay a cancellation fee.

    • Adobe, for all their faults, can hardly be said to be more malicious or greedy than Google.

      Adobe, at least, makes money by selling software. Google makes money by capturing eyeballs; only incidentally does anything they do benefit the user.

  • Did... someone make a bot to try to post a summary to HN with an LLM that also completely fails at being accurate (which is incredibly fitting given what the topic here is)

Cool, but it's still unusable for me. Somehow all my prompts are violating the rules, huh?

Nano Banana Pro sounds like classic Google branding: quirky name, serious tech underneath. I’m curious whether the “Pro” here is about actual professional‑grade features or just marketing polish. Either way, it’s another reminder that naming can shape expectations as much as specs.
