Mistral Large 3
675B open-weight MoE, Apache 2.0 — the largest open model from a major lab
Verdict
675B total / 41B active MoE, 262K context, fully Apache 2.0 — download it, fine-tune it, run it on your own hardware, no license negotiation. At $0.50/$1.50 per million tokens via Mistral's own API it is also cheap if you would rather not self-host. The strongest fully-open option in this catalog right now for teams that need both frontier-adjacent quality and real data-residency control.
