At this point if a Google PM handed me $100 and said "go figure out how to issue a prompt to Gemini 4 Argon" I'm only ~30% sure I could figure out how. The Gemini app in my phone only has 3.8 Pro as the latest model; it does say "Ultra" in the bottom left, but I really don't think I'm on the Ultra plan. How I would sign up for that, on a Workspace account, is beyond our brightest minds.

Its sad watching them try to keep up when they want nothing more than to crumble under the weight of their own bureaucracy, and at this point I'm not sure there's any hope for them.

This model is not for you or me. This model is for Google AI engineers to put on their perf review at the end of the year. How you find or not find it, it doesn't matter. It goes into the "designed and developed Gemini 4 Carbon Ultra Pro" paragraph and people get a promotion, get to keep their jobs and hope to not get replaced by Gemini 4 Carbon next year.

I remember a year ago and a bit ago trying to get an api key for some Gemini ~3 model. I probably spent an hour trying to find how to get a key in AI Studio. Finally figure it out and got a key.

I needed batch mode. Oh but the key from service X doesn't support batch mode, you need to go service Y and btw there is no UI for that so you need to use an SDK or API (cant even remember anymore). Spend an hour figuring that out, then it turns out I can't use batch mode because I don't have permissions. Have boss spend an hour granting me permissions. Then service is unavailable every n requests for 5 minutes, so I have fuck with exponential back offs.

Glad to see they moved that experience to their consumer offerings lol.

Model selector at the top drops down and shows

* 3.5 Flash-Lite

* 3.8 Flash

* 3.1 Pro

* 4 Argon - New

And honestly, the versions are hurting their case. I ask myself “how is the oldest model, the Pro model?”

This kind of bungled naming and versioning is the kind of thing I expect from Microsoft.

There's no 3.8 Pro. However, there's a 3.8 Flash that's only available with Pro or Ultra subscription.

It's at least not worse than Microsoft. Go and start a chat with Copilot. Which one? I don't know, they are all the same. Or maybe they are all different? All I know that if you start a chat in one interface, there is close to a 0% chance (but not quite) that you will find the same chat in another interface.
I had Claude write me a script to probe all the GCP Vertex models. I can say with confidence that I know how to call Argon, because Claude told me how, I did it, saw it was modestly better than Flash for my use case and I decided it wasn't worth the money right now, for this use case.

I'm fairly confident I can't call Carbon, and I am okay with that.

I just spent 10m trying to use this.

It is the most awful product experience I’ve had this year. How could they fuck it up this badly?

Unironically it's easier through third parties. Cursor has had Argon available, but in our enterprise we cannot get argon from the gemini subscription because they have some weird license split going on.

I don't even read Google's release notes anymore. What's the point? The models are never available.

Now, I just go straight to the Hacker News comments. I've given up on trying to figure out how to navigate Google's labyrinth.

Their release notes have become like breakthroughs in graphene. I'll believe it when I see it.

Their go-to-market execution is just so broken.

At the beginning of this whole AI shift, when Google would announce a new model, I would try to get access, even paying for a subscription.

Then I realized it's just not possible.

Google onboarding is the new Gordian knot.

For Google, I think the announcement is the success criteria. And onboarding is somebody else's problem. And the problem is... that somebody doesn't work at Google, or are entirely disempowered.

If, someday, Hacker News comments indicate that a majority of individuals have figured out how to access these newly announced models consistently, I might take my precious personal time to navigate the labyrinth once more.

All I see is 3.1 pro and 3.6 flash, I just canceled the sub lol - those seem like half a year old and I'm too lazy to check - my workplace gives me access to all models in a harness anyways
Tried to add AI Ultra or Pro to my business workspace account and I wasn't able to do that a few months back, then tried again when Gemini 3.8 news came out, failed again, then finally upgraded my personal account to AI Pro, tried gemini 3.8 flash on my projects, it was worst model ever. The only benifit I got by having AI Pro is that you can use Youtube adsfree.
I too could not figure it out. Also a shame the Vertex API format is sorta different to OpenAI's, which everyone but Anthropic uses. The sanest way to use Google AI models is via OpenRouter tbh.
Google's UI is always bafflingly overcomplicated and opaque. I never understand why such a large bunch of very intelligent people cannot create a useful UI

At least in my app I have Argon, but that said you can pretty easily prompt it if you have gcp subscription or through openrouter.
I thought Gemini 4 Argon is still not publicly released.

Gemini on my phone has a "4 Argon' option. I have the plan through Google One.
Not disagreeing with the premise - I've fought with this in the past - but I'm using Antigravity CLI and Antigravity desktop (GUI), and both automatically started defaulting to Argon 4 as their model a while back.

I have an AI Pro account - which I decided was a no-brainer because of the 5TB of Gmail / GDrive / GPhotos space it gives - and this all just comes along with that.

One thing to check, though, is that the client is running the latest version. At one point my Antigravity GUI, which had been working fine, started listing only Claude and GPT-OSS models. It turned out to be because the GUI needed to be updated. I guess the Google API endpoint had changed behavior without any backward compatibility.

So yeah, they're hilariously bad at rollouts, but it's not that difficult if you're technically inclined or ask an LLM.

I’m with you on this. I tried to get Argon access for our org and failed. gave up. moved on. Still just 3.8 in the dropdown for us.. Thinking its just in so Ai studio app or something and not in gemini app?
Why is it so hard for a decent PM, Designer, and Eng team to build out a better version of Antigravtity with an equivalent web interface for general chat? I don't get it.
Same here. When I use the Gemini app for iOS, it says that I’m on “Ultra” in the left sidebar near the bottom. It doesn’t say that when I’m using Gemini on the web.
Your workspace admin need to get AI Expanded Access plan.
I think it's intentional for balancing a demand profile rather than spiking their massive user base onto a new model all at once
the charitable explanation is that they derive the most important revenue in this area from enterprise. And enterprises are not allergic to horrible product experiences and upsells.

The more likely explanation (even if the above is technically true) is that Google is not good at cohesive product experiences.

I tend to wait until it shows up in Google AI Studio. That is there web interface at least, no idea for mobile.

Guys, please don't interrupt them in this endeavour.
It literally says Argon right where you select all models (3.5 Flash Lite, 3.8 Flash, 3.1 Pro, 4 Argon).

This isn't rocket science. You're just bitching because your account doesn't have the latest model rolled out yet

If you'd like to see how it compares against other SOTA models-

https://youtu.be/NO2I3ueVQrk?is=OWezDVBL3l2EHMbR

Tldr; it's about as good as sol. Opus 5.5 is still generally the best though carbon can be very good.

The Android app (and OS while we're at it) is such a horrible mess compared to Claude, just pure horror coming from Google, i'd be ashamed...
> Its sad watching them try to keep up

"try to keep up" ?

Benchmarks are just benchmarks and they could have been carefully selected but it's not "trying to keep up": they're ahead of Fable 5.1 and GTP 6 Astra in 15 of the 17 benchmarks. And in many cases by a huge margin.

Instead of talking about that, let's talk about how difficult it is to pick the model or how crazy Google's product naming methodology is.

Not saying they're not concerns: but let's not downplay what the model is achieving by saying they're "trying to pick up" because switching model ain't as easy as with the competition.

I mean: I don't use a model based on how easy it is to switch to another model. That's not what I'm looking for.
