Mistral releases open weights for Large 4

Mistral released open weights for Mistral Large 4 on Oct. 29, 2026, after a public preview earlier in the month, and priced the API at $0.70 per million input tokens, $0.07 cached, and $2.10 output. The company calls it a 1-trillion-parameter multimodal model and says it leads open-weight models on FrontierCode 2.0 at 19.7% and on Terminal-Bench 4.0 at 41%. The license is a modified MIT license that requires a separate commercial license for model-as-a-service use, and the post names Microsoft Foundry and Nvidia NIM as hosted options.
