Mistral releases open weights for Mistral Large 4, a 1T-parameter model
On Oct 29 Mistral published weights for an improved Mistral Large 4, after a public preview earlier in October. The 1T-parameter multimodal model got about three more weeks of RL on coding and defensive security.
Why it matters
Mistral reports 41% on Terminal-Bench 4.0, up 13 points from the preview, and 84.5% on BrowseComp. It is a large open-weight option from Europe, but companies selling it as a hosted service need a separate commercial license.
How to try
Download mistralai/Mistral-Large-4-1T-A52B from Hugging Face and serve it with vLLM or SGLang, or call it through the Mistral API or OpenRouter.
