Gemini 3 Flash is very good at the search task (it benchmarks quite close to 3 Pro in coding tasks but is much faster). I believe Amp switch to Gemini Flash for their search agent because it is better.
Gemini the model is good, Gemini the framework around the model is a steaming pile of crap.
I very much doubt this. I've been using gemini whenever I get hit by codex limits over the past week. 3 pro is very good - a bit behind codex but still very useful. I've tried 3 flash several times and each time what I got back was complete garbage. After the third or fourth attempt I stopped trying.
