Why this model scores 79.8
Strong agentic coding, long-running execution, open weights, self-hosting on four GPUs, and broad API and product availability create high autonomy and diffusion, while capability remains below the closed frontier.
News tied to Mistral Medium 3.5
The model score of 79.8 rates this model's risk profile. The overall Doom Index of 66.8 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.
