Strong general reasoning, tool use, and broad ChatGPT and API access drive high capability and deployment, while hosted access and safety controls moderate residual control difficulty.
News tied to GPT-5.2 Thinking
The model score of 81.1 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.
