Mistral Large 4 model card (Hugging Face)
Summary
Mistral's Hugging Face model card for Mistral Large 4, which became publicly viewable
by 2026-11-01, keeping the promise of open weights "at the end of October". The card
describes a natively multimodal mixture-of-experts model with about 1T total parameters,
about 49B active per token (52B counting embeddings and output layers), and a 1M-token
context. The weights come under the Mistral Ecosystem Open-Weight License, a modified MIT
licence. The card gives no release date; date_published is an estimate (the repo was
private and returned 401 on 2026-10-29).
Key points
- Repos:
mistralai/Mistral-Large-4-1T-A52B(repo created 2026-09-30) and an NVFP4 quantised checkpoint,Mistral-Large-4-1T-A52B-NVFP4(created 2026-10-15). The page is public with no gating notice and showed about 2,900 downloads in the last month on 2026-11-01. - Licence: commercial and non-commercial use are allowed, but offering the model as a service needs a separate commercial licence from Mistral. This is stricter than Large 3's Apache 2.0.
- Size: about 1T total / 49B active (52B with embeddings and output layers); 1M context.
- API: also served as
mistral-large-4on Mistral's API.
Why it matters
Mistral kept its promise to release the weights of its largest model, but moved from Apache 2.0 to a licence that, like GLM-5.3's, restricts model-as-a-service providers. That supports the trend toward "open, except for competing API hosts" licences.
