Yeah, in most threads you will see anyone recommending Gemini be downvoted. Ironically, Gemini (with Workspace subscription) is the only model that explicitly states it doesn't use your inputs to train their models right under the chat box. AFAIK no other provider does that explicitly - usually there is a hidden toggle in settings you will need to turn off.
TIL. That's cool. I mostly use Gemini 3 Flash for some background jobs because of the price/perf, but rooting for their models to improve. Competition is good.
