3.8 Flash is just quite good, and so is the Antigravity harness.
I use a mix of Fable 5.1, Opus 5.5, and Gemini 3.8 Flash and Gemini holds it's own. Especially in writing, frontend, and sysadmin work. agy for configuring a NixOS system has been truly incredible.
I found 3.8 Flash in Agy to be generally better than GPT 6, and only behind from Opus 5.5.
I couldn’t find a way to decline model training and reduce data retention for antigravity or Gemini. Apparently it’s only available on a business/enterprise plan, not personal. Did you manage to solve it? That’s the only reason I don’t use Gemini or antigravity.
I use Antigravity but for some reason, `agy` in the command line feels very bad/incapable of doing things. I can't quite explain it but the most common issue I run into it is just hanging on being unable to finish a tool call
Your comment made me try agy again, but after having to approve and persist every single read tool, I got fatigued really fast. Oh-my-pi shows that these checks aren't really necessary for harness safety, it's best to invest in harness predictability.
Same! 3.8 Flash does really well for writing code as long as you give it a good design and plan to follow. I use Opus for architecture/design/implementation plans and let Gemini 3.8 work using those. Even on the $20 Pro plan I've only come down to 10% before the weekly reset.
I tried antigravity a little while ago and it was utterly useless for Objective-C code, tasks that both Claude and Codex handled just fine.
Not only could it not complete the small task, the code was obviously wrong from looking at it and did not even compile.
When I pointed that out it got pissy and insisted the code was perfect and I didn't know how to use a compiler, or the compiler was buggy. Pasting the compiler errors did not help.
Surreal.

Is that a reference to https://xkcd.com/353/
Even if agy was the best (it's not, and is missing basic features) you wouldn't rather have a choice?
I cancelled Ultra because they forced me into their harness like I should adapt to them, rather than the other way around.
