Why this model scores 82.9
Strong reasoning and exceptionally long tool chains produce high autonomy, while open weights and active APIs create broad deployment, misuse opportunity, and limited central control.
News tied to Kimi K2 Thinking
The model score of 82.9 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.
