Mistral Large 4 is a mixture-of-experts model with about 1T total parameters, of which 52B are active for each token. Mistral AI lists a context window of 1M tokens. The model accepts text and image input.
The weights are released under the Mistral Ecosystem Open-Weight License, a modified version of the MIT license. Commercial use is allowed with conditions. A company that operates a Model-as-a-Service business, meaning it gives third parties access to the model for inference or post-training, needs a separate commercial license from Mistral AI. Internal use is exempt.
The official download is about 1060.5 GB in FP8. All parameters must be loaded, so the model needs a multi-GPU server; the memory calculator shows which setups fit.
