Mistral Releases le Chonk Weights, Requires License for Model-As-A-Service

Mistral released the open weights for Mistral Large 4 (Le Chonk), a 1-trillion-parameter multimodal model it says leads open-weight coding and cybersecurity benchmarks. The model ships under a modified MIT license that requires a separate commercial license for model-as-a-service providers. Mistral prices it at $0.70 per million input tokens and $2.10 per million output tokens.

• Mistral says Mistral Large 4 scores 19.7% on Cognition's private FrontierCode 2.0 benchmark, leading open-weight models.
• Booz Allen's Brad Medairy says testing matched vulnerability detection recall rates of other frontier cyber models at a compelling cost.
• Mistral says High is the default reasoning mode, recommended for the hardest use cases requiring high precision.
