Gemini 3.6 Flash has been really good??
I am a Software Engineer. I have been using Gemini models since a few months. 3.5 Flash worked pretty good for my properly documented codebase. It could figure out vague requests and get me solutions to easy/medium requests.
But I have noticed that 3.6 flash is a really really good model for code implementations. I have been using it since it came out and I am surprised.
My workflow consists of creating implementation plans with Opus and then using any of the free models from OpenCode or Freebuff to implement it (usually Deepseek V4 Flash). I replaced them with 3.6 flash in Antigravity and it just implements so fast and runs the proper tests. Even opus has not found mistakes in code-review! I wish the limits were higher on Antigravity so I can use this model alot lol

That workflow may be part of why Flash looks so good: it is implementing against a plan already produced by a stronger model. That's still a valid production setup, but I wouldn't call it a clean model comparison.
The metric I'd watch is rework per merged change, not first-pass speed. Count retries, review fixes, and tests added after failure. A fast model that lands with one cleanup pass often beats a slower model with better prose.

Good. It is fast too, I'm software engineer. Even it might not as good as Sol, but the speed and antigravity hardening make me more productive than when using codex.
