To everyone saying not available yet: it looks from the page like Pro and Ultra subscribers have it today and given the play links, it'll probably show up in the API in a few hours.

In agy 1.3.4
> Gemini 4 Argon (Medium)
Yeah this is confusing, the announcement pages claim it's both, but the app itself claims it's ultra only... Maybe a slow rollout?
Both for gemini app / website, antigravity only for Ultra (because let's be honest, that's the way to put a lot more load on it)
OpenRouter seems to have it: https://openrouter.ai/google/gemini-4-argon
It's available for me (pro sub) in Antigravity after I ran an update.
edit: It failed on the second prompt and they disabled it now.
Antigravity tells me specifically "Gemini 4 Argon is currently available to Ultra plan subscribers"
Interesting, Google's own article says it's rolling out today to Ultra subscribers. No mention of Pro.

Weirdly, the post OP linked says:
> Gemini 4 Argon is available today for Google AI Pro and Ultra subscribers

Huh ? Am also on Pro sub but Antigravity IDE say's that it's only available for Ultra users.
EDIT:
Apparently Ultra subscribers gets Argon everywhere including in Google Antigravity
Pro subscribers only get them in Gemini app and Search
[dead]
Lies!
It looks like Pro can use argon in the Gemini app, but not in antigravity:

Why the hell would I care about it on my phone? Jebus, Google is bad at products.
Im on pro, installed gemini app, tried argon 4, keeps failing with 404, resource now found. Switched to gemini-3.8-flash in same session... worked.
It seems to be rolling out gradually.. not available at once to everyone.
Same. It just told me "agent execution terminated due to an error". There was a little chevron underneath it that let me expand the error to view more. I was hoping to see what the error was, so I clicked it, and it said... "agent execution terminated due to an error".
It's crazy to me how care there is in most of these vibe-coded vibe-coding harnesses. I don't like oai's models much but I have to say their UI has by far the best attention to detail of any major player.
Available in agy for me as of now, I'm running my new model benmark of having it do comprehensive code audit on one of my more complex projects, it spun up 1 subagent per audit section and it took ~10 minutes per subagent on an 800k LOC, 60k complexity, ~4k file project. Will take me much longer to go through and determine the quality of the audit work.
What do you mean 60k complexity?

Pro subscriber in the EU (via Indian discount code) and don't have it.
OK, now I have it too (2-4 hours later).
It's showing up in Antigravity on mobile UI as "unavailable" for Pro user (you can use Remote Control to access its web UI).
It doesn't show in the desktop UI.
I'm a Pro user and I do not have it. Seems scuffed.
> Seems scuffed.
I like this phrasing and am curious what new word or phrase we might use to describe big companies over pushing Ai internally at the expense of their product quality. This pattern is so ubiquitous across google cloud products I have taken to calling them the 21st century IBM, having been a IBM baby and witnessing first hand their fall from exceptionalism.
The internet and gaming has ruined my brain because scuffed was a way to describe a bad dungeon run in mythic plus dungeons in WoW, or a bad tower dive in LoL a few years ago. I see scuffed and think "here's a WoW/League knower".

HP is the other company to consider as analogous. And maybe more explicitly so, as they had a similar "engineering first" internal culture that degraded markedly over time to be a shadow of their former self.
And took similar companies that were quality engineering focused -- like DEC or Palm -- down with them through acquisition.

I'm getting popup that I need to be Ultra :D
I'm Ultra and seeing it now (US)
Not really this is how they always release stuff in batches so can roll back if something is wrong so people get access over time
I'm on Pro and it's trying to get me to upgrade to Ultra in the AI Studio UI when using Argon. In Antigravity CLI and the Gemini website it's not showing up at all despite being logged in
Not available to me on gemini.google.com (Pro, USA).
Nope only Ultra. I went into Antigravity to check
As far as I can tell, I can successfully call Gemini 4 via API now.
Checked, and already in Antigravity (as the page said).
Pro user here, don't see it in the Gemini app
I couldn't see it either, then I clicked the 'Antigravity' button in the top right, switched back to the main screen, and it appeared in the model selector.
This is in the Gemini app on macOS.
Pro user - I can't see it.
As a plus user, web page suggests me to upgrade to PRO to use Argon .Thank god, I didn't updagrade
