Mistral 3 model family
Mistral's frontier model generation, headlined by Mistral Large 3 - a 675B-parameter sparse mixture-of-experts model (41B active) released open-weight under Apache 2.0 in December 2025 - alongside Mistral Medium 3.5 (the 'first flagship merged model,' default in Vibe since May 2026) and the efficient Mistral Small 4. A next-generation 'fat but sparse' MoE frontier model entered partner early access in July 2026.
