One thing I would love to have fixed - I type in a prompt, the model produces 90% or even 100% of the answer, and then shows an error that the system is at capacity and can't produce an answer. And then the response that has already been provided is removed! Please just make it where I can still have access to the response that has been provided, even if it is incomplete.

The biggest complaint I (and several others) have is that we continuously hit the limit via the UI after even just a few intensive queries. Of course, we can use the console API, but then we lose ability to have things like Projects, etc.

Do you foresee these limitations increasing anytime soon?

Quick Edit: Just wanted to also say thank you for all your hard work, Claude has been phenomenal.

Claude is my go to llm for everything, sounds corny but it's literally expanding the circle of what I can reasonably learn, manyfold. Right now I'm attempting to read old philosophical texts (without any background in similar disciplines), and without claude's help to explain the dense language in simpler terms & discuss its ideas, give me historical contexts, explaining why it was written this or that way, compare it against newer ideas - I would've given up many times.

At work I used it many times daily in development. It's concise mode is a breath of fresh air compared to any other llm I've tried. It has helped me find bugs in foreign code bases, explain me the techstack, written bash scripts, saving me dozens of hours of work & many nerves. It generally makes me reach places I wouldn't without due to time constraints & nerves.

The only nitpick is that the service reliability is a bit worse than others, forcing me sometimes to switch to others. This is probably a hard to answer question, but are there plans to improve that?

I'm in the middle of a particularly nasty refactor of some legacy React component code (hasn't been touched in 6 years, old class based pattern, tons of methods, why, oh, why did we do XYZ) at work and have been using Aider for the last few days and have been hitting a wall. I've been digging through Aider's source code on Github to pull out prompts and try to write my own little helper script.

So, perfect timing on this release for me! I decided to install Claude Code and it is making short work of this. I love the interface. I love the personality ("Ruminating", "Schlepping", etc).

Just an all around fantastic job!

(This makes me especially bummed that I really messed up my OA awhile back for you guys. I'll try again in a few months!)

Keep on doing great work. Thank you!

Just started playing with the command-line tool. First reaction (after using it for 5 minutes): I've been using `aider` as a daily driver, with Claude 3.5, for a while now. One of the things I appreciate about aider is that it tells you how much each query cost, and what your total cost is this session. This makes it low-key easy to keep tabs on the cost of what I'm doing. Any chance you could add that to claude-code?

I'd also love to have it in a language that can be compiled, like golang or rust, but I recognize a rewrite might be more effort than it's worth. (Although maybe less with claude code to help you?)

EDIT: OK, 10 minutes in, and it seems to have major issues doing basic patches to my Golang code; the most recent thing it did was add a line with incorrect indentation, then try three times to update it with the correct indentation, getting "String to replace not found in file" each time. Aider with claude 3.5 does this really well -- not sure what the counfounding issue is here, but might be worth taking a look at their prompt & patch format to see how they do it.

One of the silver bullets of Claude, in the context of coding, is that it does NOT use RAG when you use it via the web interface. Sure, you burn your tokens but the model sees everything and this let it reply in a much better way. Is Claude Code doing the same and just doing document-level RAG, so that if a document is relevant and if it fits, all the document will be put inside the context window? I really hope so! Also, this means that splitting large code bases into manageable file sizes will make more and more sense. Another Q: is the context size of Sonnet 3.7 the same of 3.5? Btw Thanks you so much for Claude Sonnet, in the latest months it changed the way I work and I'm able to do a lot more, now.

Been a long time casual — i.e. happy to fix my code by asking questions and copy/pasting individual snippets via the chat interface. Decided to give the `claude` terminal tool a run and have to admit it looks like a fantastic tool.

Haven't tried to build a modern JS web app in years — it took the claude tool just a few minutes of prompting to convert and refactor an old clunky tool into a proper project structure, and using svelte and vite and tailwind (which I haven't built with before). Trying to learn how to even scaffold a modern app has felt daunting and this eliminates 99% of that friction.

One funny quirk: I asked it to build a test suite (I know zilch about JS testing frameworks, so it picked vitest for me) for the newly refactored app. I noticed that 3 of the 20 tests failed and so I asked it to run vitest for itself and fix the failing things. 2 minutes later, and now 7 tests were failing...

Which is very funny to me, but also not a big deal. Again, it's such a chore to research test libs and then set things up to their conventions. That the claude tool built a very usable scaffold that I can then edit and iterate on is such a huge benefit by itself, I don't need (nor desire) the AI to be complete turnkey solution.

Anthropic is back and cementing its place as the creator of the best coding models—bravo!

With Claude Code, the goal is clearly to take a slice of Cursor and its competitors' market share. I expected this to happen eventually.

The app layer has barely any moat, so any successful app with the potential to generate significant revenue will eventually be absorbed by foundation model companies in their quest for growth and profits.

Why not just open source Claude Code? people have tried to reverse eng the minified version https://gist.githubusercontent.com/1rgs/e4e13ac9aba301bcec28...

Hi Boris, love working with Claude! I do have a question—is there a plan to have Claude 3.5 Sonnet (or even 3.7!) made available on ca-central-1 for Amazon Bedrock anytime soon? My company is based in Canada and we deal with customer information that is required to stay within Canada, and the most recent model from Anthropic we have available to us is Claude 3.

A minor ChatGPT feature I miss with Claude is temporary chats. I use ChatGPT for a lot of random one-off questions and don’t want them filling up my chat history with so many conversations.

Hi and congrats on the launch!

Will check out Claude Code soon, but in the meantime one unrelated other feature request: Moving existing chats into a project. I have a number of old-ish but super-useful and valuable chats (that are superficially unrelated) that I would like to bring together in a project.

I really want to try your AI models, but "You must have a valid phone number to use Anthropic's services." is a show-stopper for me.

It's the only mainstream AI service that requests this information. After a string of security lapses by many of your competitors, I have zero faith in the ability of a "fast moving" AI-focused company to keep my PII data secure.

Does the fact its so ungodly expensive and highly rate limited kind of prove the modern point that AI actually uses tons of water and electricity per prompt? People are used to streaming YouTube while they sleep and it's hard to think of other web technology this intensive. OpenAI is hostile to this subject. Does Claude have plans to tackle this?

Is there / are you planning a way to set $ limits per API key? Far as I can tell the "Spend limits" are currently per-org only which seems problematic.

Hi! I’ve been using Claude for macOS and iOS coding for a while, and it’s mostly great, but it’s always using deprecated APIs, even if I instruct it not to. It will correct the mistake if I ask it to, but then in later iterations, it will sometimes switch back to using a deprecated API. It also produces a lot of code that just doesn’t compile, so a lot of time is spent fixing the made up or deprecated APIs.

Awesome to see a new Claude model - since 3.5 its been my go-to for all code related tasks.

I'd really like to use Claude Code in some of my projects vs just sharing snippets via the UI but I'm curious how might doing this from our source directory affect our IP including NDA's, trade secret protections, prior disclosure rules on (future) patents, open source licensing restrictions re: redistribution etc?

Also hi Erik! - Rob

Hi Boris et al, can you comment on increased conversation lengths or limits through the UI? I didn't see that mentioned in the blog post, but it is a continued major concern of $20/month Claude.ai users. Is this an issue that should be fixed now or still waiting on a larger deployment via Amazon or something? If not now, when can users expect the conversation length limitations will be increased?

It would be great if we could upgrade API rate limits. I've tried "contacting sales" a few times and never received a response.

edit: note that my team mostly hits rate limits using things like aider and goose. 80k input token is not enough when in a flow, and I would love to experiment with a multi-agent workflow using claude

Now that the world's gotten used to the existence of AI, any hope on removing the guardrails on Claude? I don't need it to answer "How do I make meth", but I would like to not have to social engineer my prompts. I'd like it to just write the code I asked for and not judge me on how ethical the code might be.

Eg Claude will refuse to write code to wget a website and parse the html if you ask it to scrape your ex girlfriend's Instagram profile, for ethical and tos reasons, but if you phrase the request differently, it'll happily go off and generate code that does that exact thing.

Asking it to scrape my ex girlfriend's Instagram profile is just a stand in for other times I've hit a problem where I've had to social engineer my way past those guard rails, but does having those guard rails really provide value on a professional level?

How is your largest customer, Cursor, taking the news that you'll be competing directly with them?

Great, thanks! Could you compare this new tool to Aider?

Do you think Claude Code is "better", in terms of capabilities and token efficiency, than other tools such as Cline, Cursor, or Aider?

Thanks for the product! Glad to hear the (so called) "safety" is being walked back on, previously Claude has been feeling a little like it is treating me as a child, excited to try it out now.

In the console, TPM limit for 3.7 is not shown (I'm tier 4). Does it mean there is no limit, or is it just pending and is "variable" until you set it to some value?

Your footnote 3 seems to imply that the low number for o1 and Grok3 is without parallelism, but I don't think it's publicly known whether they use internal parallelism? So perhaps the low number already uses parallelism, while the high number uses even more parallelism?

Also, curious if you have any intuition as to why the no-parallelism number for AIME with Claude (61.3%) is quite low (e.g., relative to R1 87.3% -- assuming it is an apples to apples comparison)?

Awesome work, Claude is amazingly good at writing code that is pretty much plug and play.

Could you speak at all about potential IDE integrations? An integration into Jetbrains IDEs would be super useful - I imagine being able to highlight a bit of code and having a plugin check the code graph to see dependencies, tests etc that might be affected by a change.

Copying and pasting code constantly is starting to seem a bit primitive.

Why gatekeep Claude Code, instead of releasing the code for it? It seems like a direct increase in revenue/API sales for your company.

What do I need to do to get unbanned? I have filled in the provided Google Docs form 3-4 times to no avail. I got banned almost immediately after joining. My best guess is that I got banned because I used a VPN. https://news.ycombinator.com/item?id=40808815

Is there a way to always accept certain commands across sessions? Specifically for things like reading or updating files I don't want to have to approve that each time I open a new repl.

Also, is there a way to switch models between 3.5-sonnet and 3.5-sonnet-thinking? Got the initial impression that the thinking model is using an excessive amount of tokens on first use.

For the pokemon benchmark, what happened after the Lt Surge gym? Did the model stall or run out of context or something similar?

A bit off topic but I wanted to let you know that anthropic is currently in violation of EU Directive 98/6/EC:

> The selling price and the unit price must be indicated in an unambiguous, easily identifiable and clearly legible manner for all products offered by traders to consumers (i.e. the final price should include value added tax and all other taxes).

I wanted to see what the annual plan would cost as it was just displaying €170+VAT, and when I clicked the upgrade button to find out (I checked everywhere on the page) then I was automatically subscribed without any confirmation and without ever seeing the final price before the transaction was completed.

Hi Boris! Thank you for your work on Claude! My one pet peeve with Claude specifically, if I may: I might be working on a Svelte codebase and Claude will happily ignore that context and provide React code. I understand why, but I’d love to see much less of a deep reliance on React for front-end code generation.

When I first started using Cursor the default behavior was for Claude to make a suggestion in the chat, and if the user agreed with it, they could click apply or cut and paste the part of it they wanted to use in their larger project. Now it seems the default behavior is for Claude to start writing files to the current working directory without regard for app structure or context (e.g., config files that are defined elsewhere claude likes to create another copy of). Why change the default to this? I could be wrong but I would guess most devs would want to review changes to their repo first.

> We’ve also improved the coding experience on Claude.ai. Our GitHub integration is now available on all Claude plans—enabling developers to connect their code repositories directly to Claude

Would love to learn a bit more about how the GitHub integration works. From https://support.anthropic.com/en/articles/10167454-using-the... it seems it’s read only.

Does Claude Code let me take a generated/edited artifact and commit it back as a PR?

hey guys! i was wondering why you chose to build Claude code via CLI when many popular choices like cursor and windsurf fork VScode. do you envision the future of Claude code to abstract away the codebase entirely?

It would be great to have a C# / .NET SDK available for Claude so it can be integrated into Semantic Kernel [0][1]. Are there any plans for this?

I'm curious why there are no results for the "Claude 3.7 Extended Thinking" on SWE-Bench and Agentic tool use.

Are you finding that extended thinking helps a lot when the whole problem can be posed in the prompt, but that it isn't a major benefit for agentic tasks?

It would be a bit surprising, but it would also mirror my experiences, and the benchmarks which show Claude 3.5 being better at agentic tasks and SWE tasks than all other models, despite not being a reasoning model.

Are you guys paying Claude for its assistance with your products

It would be amazing to be able to use an API key to submit prompts that use our Project Knowledge. That doesn't seem to be currently possible, right?

From the release you say: "[..] in developing our reasoning models, we’ve optimized somewhat less for math and computer science competition problems, and instead shifted focus towards real-world tasks that better reflect how businesses actually use LLMs."

Can you tell us more about the trade-offs here?

Also, are you using synthetic data for improving the responses here, or are you purely leveraging data from usage/partner's usage?

Thank you for the update!

I recently attempted to use the Google Drive integration but didn't follow through with connecting because Claude wanted access to my entire Google Drive. I understand this simplifies the user experience and reduced time to ship, but is there anyway the team can add "reduce the access scope of Google Drive integration" to your backlog. Thank you!

Also, I just caught the new Github integration. Awesome.

Small UX suggestion, but could you make submission of prompt via URL parameter work? It used to be possible via https://claude.ai/new?q={query}, but that stopped working. It works for ChatGPT, Grok, and DeepSeek. With Claude you have to go and manually click the submit button.

Who the heck is on your UX team?

WHY is a huge % of my UX filled with nothing? I would apprececiate metrics, token graphs etc

Why so much wasted space? ... >>??

Did you guys ever fix the issue where if UK users wanted to use the API they have to provide a VAT number?

Love the UI so far. The experience feels very inspired by Aider, which is my current choice. Thanks!

Serious question: What advice would you give to a Computer Science student in light of these tools?

The thing I would like automated is highlighting a function in my code then ask the AI to move it to a new module-file and import that new module.

I would like this to happen easily like hitting a menu or button without having to write an elaborate "prompt" every time.

Is this possible?

Hi there. There are lots of phrases/patterns that Claude always uses when writing and it was very frustrating with 3.5. I can see with 3.7 those persist. Is there any way for me to contact you and show those so you can hopefully address them?

Any change there will be a way to copy and paste the responses into other text boxes (i.e., a new email) and not have to re-jig the formatting?

Lists, numbers, tabs, etc. are all a little time consuming... minor annoyance but thought I'd share.

Can you give some insight into how you chose the reply limit length? It seems to cut off many useful programs that are 80%-90% done and if the limit were just a little higher it would be a source of extraordinary benefit.

Congrats on the launch! You said its an important tool for you (Claude Code) how does this fit in with Co-Pilot, Cursor, etc. Do you/your teammates only rely on Claude Code? What do you reach for for different tasks?

Is there plans to add websearch function over some core websites (SO, API docs)? Competitors have it, and in my experience this provide very good grounding for coding tasks (way less API functions hallucinated).

What kind of sorcery did you use to create Claude? Honest question :)

Does this actually have an 8k (or more) output context via the API?

3.5 did with a beta header but while 3.6 claimed to, it always cut its responses after 4k.

IIRC someone reported it on GH but had no reply.

Any way to parallelize tool use? When I go into a repo and ask "what's in here", I'm aiming for a summary that returns in 20 seconds.

My key got killed months ago when I tested it on a PDF, and support never got back to me so I am waiting for OpenRouter support!

Hi, what are the privacy terms for Claude Code? Is it memorizing the codebase it’s helping with? From an enterprise standpoint

Thank you to the team. Looks like a great release. Already switching existing prompts to Claude 3.7 to see the eval results :)

Thanks for this - exciting launch. Do you have examples of cool applications or demos that the HN crowd should check out?

Hi Boris,

Would it be possible to bring back sonnet 2024 June?

That model was the most attentive.

Because we lost that model this release a value loss for me personally.

I tried signing up to use Claude about 6 months ago and ran into an error on the signup page. For some reason this completely locked me out from signing up since a phone number was tied to the login. I have submitted requests to get removed from this blacklist and heard nothing. The times I have tried to reach out on Twitter were never responded to. Has the customer support improved in the last 6 months?

Not a question but thank you for helping make awesome software that helps us make awesome software, too :)

Can you let the API team know that the /v1/models endpoint has been broken for hours? Thanks.

with Claude coder, how does history work? I used it with my account, ran out of credit then switched to a work account but there was no chat history or other saved context of the work that had been done. I logged back in with my account to try copy it but it was gone.

Did you run the Aider benchmarks to get a comparison of Claude Code vs. Aider?

Any updates on web search?

When are you providing an alternative to email magic login links?

What are your thoughts on having a UI/design benchmark?

Which starter pokemon does Claude typically choose?

Will Claude be available on Azure?

when there are two commands in a prompt example

do A and then do B.

the model completely ignores the second task B.

will you guys allow remote work ever for engineers?

CLAUDE NUMBA ONE!!!

Congrats on the new release!

Hi @eschluntz, @catherinewu, @wolffiex, @bdr. Glad that you are so plucky and upbeat!

How do you feel about raking in millions while attempting to make us all unemployed?

How do you feel about stealing open source code and stripping the copyright?

Have you seen https://mycoder.ai? Seems quite similar. It was my own invention and it seems that you guys are thinking along similar lines - incredibly similar lines.

Folks, let me tell you, AI is a big league player, it's a real winner, believe me. Nobody knows more about AI than I do, and I can tell you, it's going to be huge, just huge. The advancements we're seeing in AI are tremendous, the best, the greatest, the most fantastic. People are saying it's going to change the world, and I'm telling you, they're right, it's going to be yuge. AI is a game-changer, a real champion, and we're going to make America great again with the help of this incredible technology, mark my words.
