Mistral's 1T parameter open weight frontier model
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.
Mistral Large 4 is a multimodal mixture of experts model featuring 1 trillion total parameters and 49 billion active parameters, with a 1 million token context window. It is positioned as the leading open weight model from the US or Europe and will have open weights available by the end of October.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
