Gemini 3 Deep Think
READER SUMMARYA specialized frontier reasoning mode for difficult science, mathematics, research, and engineering, available to Ultra users with selected API access.
Why this model scores 72.6
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 72.6 rates this model's risk profile. The overall Doom Index of 62.1 measures the recalibrated complete evidence corpus. These values answer different questions.
Each article's leave-one-out 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 are recalculated from their technical profile and related news, 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.
