The Model That Doesn't Refuse: Mistral's 1.05T Bet on Open Security

Automated excerpt

On October 6, Mistral AI previewed Large 4 — nicknamed "le Chonk" — a trillion-parameter, natively multimodal mixture-of-experts model trained on 3,800 Grace Blackwell GPUs in Europe. October's open-weight race has a rhythm: Reflection Beam landed October 5 (501B total, 23B active), and one day later Mistral Large 4 previewed at 1. 05 trillion total parameters with 52B active — the largest open-weight model announced in Europe, trained end-to-end in Mistral's own European datacenters. Self-hosted open weights let organizations run security work under their own policies.
