Mistral Large 4

Mistral Large 4 (public preview, also called ML4 or "le Chonk") is Mistral AI's flagship general-purpose multimodal mixture-of-experts model. Mistral's docs describe it as 1.05T total parameters with 52B active parameters and a 1.6B vision encoder, while the Hugging Face upcoming-release page describes a 1T model with 49B active parameters per token. It supports a 1M-token context window with text and image input and text output, plus structured outputs, function calling, document QnA, batching, agents and conversations, and built-in tools. Launch API pricing is 50% off for two weeks: $0.68/$0.07/$2.09 per million input/cached/output tokens versus $1.36/$0.14/$4.18 list. Weights are planned for the end of October 2026, so the model is stored as proprietary until a public weights license is published. Catalog scores are self-reported from the Mistral launch announcement.
