Mistral says Large 4, a 1-trillion-parameter multimodal model, is open-weight under a modified MIT licence; a business selling it as a service must take a separate licence.
- Mistral says it is releasing the weights of Mistral Large 4, a 1-trillion-parameter, natively multimodal mixture-of-experts model with 49B active parameters per token.
- Use, modification, fine-tuning and commercialisation are allowed, but a business that operates a Model-as-a-Service offering must get a separate commercial licence from Mistral.
- Mistral lists API prices of $0.70 per million input tokens, $0.07 per million for cached input and $2.10 per million output tokens.
If you plan to host Large 4 for customers, read the Mistral Ecosystem Open-Weight License before you commit. Mistral says a business that operates a Model-as-a-Service offering needs a separate commercial licence, while use, modification and fine-tuning are allowed. So the licence terms depend on how you use the weights as well as on the download. The benchmark results, including the 48% Mistral reports on the Artificial Analysis Coding Agent Index, are Mistral's own account and worth testing. Before you switch, run Large 4 on your own tasks and compare its listed prices of $0.70 and $2.10 per million tokens with what you pay now. Read on →
