TLDR
Gemini 4 Argon is a very strong multimodal model, but it is not the best on leaderboards or for agentic coding. Its real value is providing Google's ecosystem—customers, products like Notebook LM, and future distillations—with a credible frontier model trained heavily on reinforcement learning for tasks combining visuals, code, and media. The million-token single response feature exists but is a nuanced API flag unlikely to see mainstream use soon.
Key points
Argon excels at multimodal tasks that combine visuals, code, and audio in a single pipeline.
It is not the best coding model; Claude Code and Codeex are better for agentic coding.
Google built Argon to give its customers a credible frontier model without leaving the Google stack.
The million-token single response is a config flag for long reasoning tasks, not a mainstream feature.
Pricing is $2 in and $10 out until December 1, but the model is expected to improve significantly soon.

Okay, so Gemini 4 Argon is now out and in this video, while I'm going to show you a few demos, I'm going to really talk about more about what this model means and how you should actually think
about this model. So, I'm going to say this right up front. This is a really, really, really good model. But is it the best model out there? I actually don't think it is. But more importantly, I
don't think that that really matters that much. And I'm going to talk about why in this video. Because what you're looking at here are some of the demos that I basically put together for this
showing where this model is genuinely strong. It's not always going to be the stuff that tops leaderboards. And in some ways, I think it's actually more interesting to understand why Google
built this model. And that requires looking past leaderboards anyway. So, when Google first announced Argon, I made a short video about it then. And sure enough, everyone was complaining
that there weren't many examples, the model wasn't available, all that stuff. Totally fair comments, by the way. So, full disclosure, I've been an early tester on this model and I had to sign
quite a few more NDAs than normal, but by the time you're watching this video, Gemini now is part of the paid tier of the Gemini API. It's going to be in anti-gravity. It's going to be in the
Gemini app. It's going to be in almost every Google surface where they're putting models. Now, often it's only going to be available if you're paying for this model, but for things like AI
mode and stuff like that, it's not just available to ultra subscribers, it's also going to be open to pro. But basically, the cool thing here is I can finally talk about what it's like to
actually use this model. All right, so where is this model actually strong? For me, the standout things here is anything that combines sort of visuals, code, and media in one kind of task. If you take a
look at something like this, which I chose to do not in anti-gravity, but just in the pure Gemini app, you can see here I'm basically saying, can you build me a music maker in the style of Rebirth
by Propeller Heads? Try to give it an 808, a 99, and a 303 and then put it together and make sure to include filters for FX and a Rolland style step sequencer. Okay, I deliberately made the
prompt here very short, right, to see, okay, what can this actually come up with? So, I've got a reference to something like Rebirth. I've got a reference to some Roland synthesizers,
drum machines in there. And sure enough, it went away and produced something which is really pretty amazing in here. If I come in and run this straight away, you can see that it's
built not only a very sophisticated interface here, but it's also then gone and actually made the sounds to this and built a little synthesizer, built something like an 808 drum machine, a
909, etc. And that's a singleshot prompt. Now, before you jump down my throat about the real world is not about using just singleshot prompts, I agree with you, right? I just felt that some
of these are actually really good to look at and get a sense of what the model can actually do with a limited set of resources. And let me explain what I'm actually mean by that. So, the model
is extremely good at doing things like Blender and doing things like game generation, those kinds of things. And clearly that's come from a lot of the reinforcement learning environments that
they've trained this model on and done a lot of work post-training it on. And it's not just one demo here. If you look at the demos that Google put out with the launch themselves, there's a pretty
clear pattern. In one of them, Argon basically scripts Blender animations, generates custom audio, pipes the whole thing through to an actual vintage CRTV. In another one of them, they build a
multi-tiered Japanese temple in the grounds using Blender. And if you look at that, that's pretty amazing to see what this thing can do when it's given an agentic loop and a proper harness
that can use those kinds of skills. And all of this feels like it's had a lot of RL on these kind of pipelines being things like Blender, 3JS, shaders, etc. And those are the kind of tasks where
the model writes the code, renders something out, looks at the result, then gradually fixes it. It's that loop of sort of code, render, look, fix something up that continuously seems to
be doing well here. Now, in this video, I don't want to get into benchmarks too much, but what I do want to say is that from everything I'm hearing, this is the biggest model that they've done
pre-training on. You'll notice in the name being Argon that it's not actually falling into the other tiers that they've had before, whether that was Flash, Pro, even Ultra, which sort of
got discontinued. And we do know for a fact that this is just the first Gemini 4 model. Now the big question people are going to ask is it as good as the anthropic models or the open AAI models
or even things like the new Muse Wonder here. So I got to say in my testing a lot of this now comes down to how you're actually using the model. I still don't think for example anti-gravity is
anywhere near as good as Claude Code or Codeex. And as of the time I'm recording this I haven't tried this in AI Studio Build for example. I've basically been either using it from the raw API in
anti-gravity or in the Gemini app. But clearly the thing here is that it's definitely good at a lot of these multimodal tasks. Now in the last video I did talk about some of the benchmarks
from the artificial analysis intelligence index where this model scores a 53 which ties it with GPT6 Astra and Fable 5.1 but quite a bit behind Opus 5.5 and even the new Sonnet
5.5. Added to that in the mix is now Meta has released Muse Wonder which also is quite a bit ahead of this model. But one of the things I will say here is that the benchmarks don't always tell
the full story. Right? This model seems to be very good at generalization. I will say it's not the best coding model. I think the other models are probably going to do better at different kinds of
coding tasks and for the whole sort of coding agent game. This model though really isn't aimed at taking those models out at their own game. So, I think if your main job is picking the
strongest model for agentic coding, you're probably going to look elsewhere. And I'm sure a lot of AI engineers are going to complain about things like that, and that's a fair call. But I
don't think that's why Google built this model. I don't think Google's actually trying to be in the game of being a standalone company that just sells tokens. If you look at the Google for
business event last week, they basically announced that they had over 500 companies now that had done more than a trillion tokens with the Gemini models. My bet is most of those are actually the
flash models, perhaps even the flashlight models. What Google was lacking was a frontier model that they could basically put out there to their customers and say, "We also have a very
good model." And that's clearly what Argon delivers here. It allows their customers to basically have a credible option of using this model if they're already a Google shop or they're looking
to use Google products. Now, Gemini for Argon gives those people a credible option without having to leave the Google stack. And I think in many ways that's the real customer here. And then
on the consumer product side, Google's needed a frontier model underneath everything that it ships. The Gemini app now has tasks that keep running when you're away from your computer. It can
connect to all these different apps. You've got notebook LM. You've got things like anti-gravity and all those things are going to benefit not only from this model, but probably from
distillations of this model to make other Gemini 4 models. Adding Argon allows the product people at Google to really focus on building the products that are working, things like Notebook
LM, and probably improving the ones that perhaps haven't gotten as much traction as they would like for things like anti-gravity and putting this in the Gemini app, the Google Workspace apps,
etc. So, I think in many ways, basically, Google here is focused on Argon as being a foundation. And in that sense, this is clearly a big win for them. While this year they've lost a lot
of the top talent that came up with a lot of the ideas for a lot of the early LLMs, Argon really shows that they've still got people there that know how to use the TPUs, know how to spin up a lot
of them, know how to do a lot of pre-training, know how to do the RL environments, and know how to put it together to actually make a frontier level model. So I think the best thing
is rather than me show you a lot of demos about what it can do, what it can't do, really at this point you should be taking your use cases into either AI Studio or the Gemini app or if
you want to anti-gravity and actually running those things yourself. I will say that in the first video I talked a lot about the million tokens in a single response. In practice it turns out it's
a lot more nuance than I originally had thought. The key thing there is that's not going to be in the Gemini app. I don't know if it's going to be in anti-gravity. Really, it's more for the
API. And it's actually a flag that you need to pass in to the config, not to actually get it to keep going. And really, you're only going to benefit properly from it if you've got a task
that requires multiple hundreds of thousands of tokens for reasoning. And while I think that's going to be interesting to see how people prompt it to get it to just keep reasoning and
reasoning and reasoning and go into that sort of loop in its reasoning, I don't see that that's going to get a lot of mainstream use. So I'd still call this sort of early days. If you're building
your own vertical harnesses and stuff like that, I probably wouldn't go out and redesign everything around the million tokens yet. That said, if you do have scientific use cases or things like
that where you can actually get really long reasoning out of it, this is certainly worth turning on for your long reasoning tasks and measuring it to see actually how it plays out for you.
Anyway, to wrap up, Argon is a really good model. It may not be at the top of the leaderboards and I'm sure many people are going to criticize it for that. But I think the real win for
Google here is just what they themselves are able to build on it and also their customers are able to build on it for different use cases. And the Google models have always been very good at
generalization for these kind of tasks. They haven't gone out trying to make the best coding model or to win every single benchmark that they're going after. What they've made is a very very strong
multimodal model that has a really good sense of a lot of intelligence that perhaps was more on the fringe in the previous models. Anyway, don't forget that the price currently is $2 in and
$10 out. That's going to last till December 1. And honestly, I'm going to say I don't think you're going to see this model still around by December 1. We know that this is not the final
checkpoint of this model. Still doing a lot of training, doing a lot of tests to how to improve it. Just like you saw with GPT6 Soul getting a massive bump when it went from six to 6.1. My guess
is that Argon is also going to get that same kind of bump in the next month or two. So anyway, I've put the links to the Google blog post and the artificial analysis in the description. If you
missed my first video on Argon, check that out. Let me know in the comments what you think and whether you think it really matters that this is not the number one model. And as always, if you
