Why this model scores 72.3
Exceptional broad reasoning and demonstrated scientific work support high capability, while specialized access and limited general action surfaces constrain autonomy and deployment.
News tied to Gemini 3 Deep Think
The model score of 72.3 rates this model's risk profile. The overall Doom Index of 66.8 measures the complete temporally weighted evidence record. These values answer different questions.
Each article's current Doom Index contribution is divided equally among the exact models named on that article. This prevents multi-model evidence from being claimed in full on several model pages. Model risk scores use a bounded temporal offset around their technical profile, but never feed back into the overall index.
Gemini 3 Deep Think advances frontier reasoning for science and engineering
Google DeepMind released an upgraded specialized reasoning mode with 84.6% on ARC-AGI-2, broad frontier evaluations, Ultra access, and selected API access. Early testers reported finding a peer-review flaw and producing a semiconductor fabrication recipe.
