GPT-5.2 Pro
READER SUMMARYHighest-compute GPT-5.2 tier for difficult professional, programming, and abstract reasoning tasks.
Why this model scores 79.9
The series' strongest reasoning tier has high capability and tool-mediated autonomy, but price, latency, Responses API access, and hosted controls materially constrain deployment.
News tied to GPT-5.2 Pro
The model score of 79.9 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.
