Mistral releases open weights for Mistral Large 4 (Le Chonk)
Mistral has released the weights of Mistral Large 4, codenamed Le Chonk, a 1-trillion-parameter natively multimodal model first shown in public preview earlier this month. Mistral says additional reinforcement learning improved agentic coding and defensive cybersecurity, and that the model leads open-weight coding benchmarks while using fewer tokens. It adds three reasoning modes and is trained on European infrastructure.
