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 just shipped its biggest model ever, and the team nicknamed it Le Chonk. It has 1 trillion parameters with 49 billion active, it understands text and images natively, and Mistral says it's the strongest open weight model built in the US or Europe. Mistral AI posted a short launch video on X here.
The cyber results are what stood out for me. Mistral Large 4 ranks in the top five on the Artificial Analysis Cyber Index, and on the test where a model has to reproduce a real vulnerability and then patch it, Mistral reports a score of 82%, the highest of any model. Several closed models score close to zero on that test because they refuse the task.
Heavy visual work is the other one I'd test first. It handles engineering drawings, dense charts, and gigapixel satellite images, which is where a lot of models still fall apart.
For builders, the weights land at the end of October so you can run it on your own servers. Mistral trained it from scratch on 3,800 NVIDIA Grace Blackwell GPUs in its own European datacenters, and the full benchmarks are in the announcement here.

@arthurmensch lfg! keep up the great work, cocorico!
We are so back! Oh wait. This is our "first" entry into this. Better late than never I suppose. EU AI FTW 🚀 Is this EU's first frontier model, that can compete with the status quo, anyone know?

Who hunted Mistral Large 4?
Mistral Large 4 was hunted by KP. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
