Gemini 3.5 Flash is TRASH in Google AI Studio Build

I’ve been trying out Gemini 3.5 Flash in AI Studio’s Build section, and I have to say the results are horrible.

I give it a simple prompt (e.g., “Make me a fun amazing high-quality pixel platformer. Have a title screen too.”), and it takes 800s to make it and there’s so many unnecessary things I didn’t even ask for, like a sound syntheziser or other things, it is extremely gptified.

I tried 3.5 Flash in Antigravity 2.0 and compared to AI Studio, it’s an incredible model. Actually does what I tell it to do and really good results.

I understand that 3.5 Flash was mainly designed and optimized for Antigravity, but it shouldn’t be this trash of a model in AI Studio Build. Gemini 3 Flash Preview is lightyears better in AI Studio build.

I’m not sure if anyone else is experiencing this issue or if it’s just me. Feedback and anything is welcome.

the 3.0 flash is lightyears better also in antigravity because it costs 15x less than the 3.5 flash and is just as good, more or less, except for slightly worse instructions following but for the price difference i’d be more than ok with it

Agreed, I swear the first few times I used it I got great results, but now I can’t get it to do anything even close to what I’m asking for.
