After several months of testing Anthropic's Claude until they started fucking it up with Opus 5 and Fable 5.1, I went back to GLM 5.3 in Z code. Today, I thought it was the right time to test Gemini 4 Argon in Antigravity because I'm finalizing a big project that I was working on for 12 months.
It turns out the model is really capable. I didn't expect that. It really loves detailed work. It has essentially the intellectual breadth of the Anthropic and OpenAI models, so it's superior to GLM 5.3, clearly.
This is a huge difference: it did not lose the ability to actually follow a tight workflow harness. For someone like me who has developed a workflow harness that helped him develop larger projects over up to 16 months, with massively growing codebases, the only thing that kept my sanity and kept the projects afloat was essentially a tight workflow framework and specific standards, procedure, and protocol.
Beginning with Opus 5 and also Fable 5.1, Anthropic and OpenAI models totally lost the ability or the willingness to actually follow workflow instructions, so they got very sloppy. They became great vibe coders and one-shotters, but they became horrible senior engineers who work reliably in a bigger, established codebase that needs targeted changes or changes based on absolute quality control. No implementation without sufficient QA.
Now it turns out that Gemini 4 Argon seems to be the best of both worlds. It's definitely more capable than GLM 5.3. It has a huge depth. It has the intelligence, and what made me really happy is that it actually really follows workflow instructions and process. Right now, to me, this is the ideal model for what I'm doing, and I really couldn't believe it when I saw this.
Antigravity, are you actually really serious in lobotomizing your best model in your own IDE to a 230,000-token context window?
I mean, are you fucking kidding me?
Do you live in 2024? Is this intentional? Is this due to limited compute, or did you just forget to upgrade this in your IDE?
You run huge promotions that your model has a maximum output of 1 million tokens. What the fuck? Who the fuck needs 1 million-token output?
You are advertising a 1 million context window, and then you are fucking lobotomizing your model at a quarter of the context window. Are you fucking serious?
Fortunately, I could immediately hack it and patch it, and now I have the full million context window when I work with Gemini 4 Argon. Why the fuck would you do that? Are you stupid?
Yeah, I almost forgot you had another clamp on it. When it comes to loading agents.md files into the system prompt, this was also capped to 24 KB.
I mean, are you fucking kidding me?
Anyone who works with Antigravity and wants the patch, just comment. I will publish it here.
Won't work with Opus 5.5, though, because this goes over Vertex. The patch only works with the Google models.
Opus 5.5 is even more limited than Gemini 4 Argon .
