What is Mistral Large 4?

Mistral Large 4 (aka Le Chonk) is Mistral's largest model yet: a natively multimodal mixture of experts model with 1T total and 49B active parameters and a 1M token context window. Mistral says it is the strongest open weight model from the US or Europe, and it ranks top 5 on the Artificial Analysis Cyber Index. It was trained in Mistral's own European datacenters. The preview API is live today on Mistral Studio, with open weights due by the end of October.
