Why this model scores 76.9
Frontier-adjacent multimodal capability and permissive weights drive deployment and control difficulty; its documented autonomy evidence trails leading closed agents.
News tied to Mistral Large 3
The model score of 76.9 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.
Mistral Large 3 brings frontier-scale multimodal AI to open weights
Mistral AI released the 675-billion-parameter Mistral Large 3 base and instruction checkpoints under Apache 2.0 with API and multi-platform access.
