Public PreviewMistral Large 4 (Le Chonk)
Public-preview natively multimodal mixture-of-experts model. Mistral's 6 Oct 2026 blog calls it a 1-trillion-parameter model with 52 billion active parameters and says the preview API is on Mistral Studio, with open weights due by the end of October. The docs page lists API identifier mistral-large-4+1, 52B active parameters, 1.05T total parameters, a 1.6B vision encoder, and a 1M context window. The Hugging Face card, still an upcoming release on 16 Oct 2026, says 49 billion active parameters per token and 52 billion including embeddings and output layers, with a current ETA of 31 Oct 2026. Artificial Analysis describes the same preview as 1T total and 49B active, with a 512k context window, and scores it 38 on the Intelligence Index and 50 on the Cyber Index. Weights were not downloadable on 16 Oct 2026, so there is no open-weight release date or public license yet.
