READER SUMMARYDeep-reasoning GPT-5.2 tier for professional work, coding, long context, tools, and complex multi-step projects.

News tied to GPT-5.2 Thinking
The model score of 80.8 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.
