Why this model scores 85.8
Higher inference compute and broad tools raise reliable expert-task capability and autonomy above o3. Paid hosted access limits diffusion, but consequential capability remains broadly reachable.
News tied to OpenAI o3-pro
The model score of 85.8 rates this model's risk profile. The overall Doom Index of 67.9 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.
