Mistral Medium 3.5
READER SUMMARYA 128-billion-parameter open-weight model optimized for long-horizon coding, multi-tool work, structured output, and persistent remote agents.
Why this model scores 79.5
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 79.5 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.
