Gemini 3 Deep Think by Google Reviews

Reviewers mostly praise Gemini 3 Deep Think for practical reasoning rather than flair. The clearest feedback comes from founders, especially the makers of Gro, kuku, and Vivago, who say it handles long context, multi-step logic, structured outputs, tool calling, low-latency file actions, and prompt rewriting for video workflows. Across other comments, people also cite strong multimodal understanding, visual generation, and natural conversation. Downsides are barely discussed, so the picture is positive but narrow and mostly builder-led.
