- Mistral announced Mistral Large 4, nicknamed Le Chonk: 1T total parameters, natively multimodal, 49B active.
- Claimed best open-weights model from US or Europe on aggregated benchmarks, SOTA on cyber defense, manufacturing and finance, and beats closed frontier models on visual grounding.
- Built end-to-end in Europe, deployable via Mistral's own EU cloud; API available today, open weights coming end of October.
- Name backstory: X users joked about a fictional giant Mistral model "Le Chaton Fat" earlier this year; CEO Arthur Mensch deliberately chose "Le Chonk" as a nod to the memes—a big chunky cat.
