For coding it is horrible. I used it exclusively for a day and switching back to Opus felt like heaven. Ok, it is not horrible, it is just significantly worse than competitors.
Although it sounds counter-intuitive, you may be better off with Gemini 3 Fast (esp. in Thinking mode) rather than Gemini 3 Pro. Fast beats Pro in some benchmarks. This is also the summary conclusion that Gemini itself offers.
Honestly if you use Traycer for plan + review (I just have it open in different IDE that they support), you can use any editor that has good models and does not throttle the context window.
I am trying to test bunch of these IDEs this month, but I just cant suffer their planning and have to outsource it.
I also get weirdly agitated by this. In my mind Geminy 3 is case of clear benchmaxing and over all massive flop.
I am currently testing different IDEs including Antigravity, and I avoid that model at all cost. I will rather pay to use different model, than use Geminy 3.
It sucks at coding compared to OpenAI and Anthropic models and it is not clearly better as chat-bot (I like the context window). The images are best part of it as it is very steerable and fast.
But WTF? This was supposed to be the OpenAI killer model? Please.
