Mistral 发布 Large 4 权重，API 标价约减半

Mistral released the weights of its 1-trillion-parameter Mistral Large 4 and roughly halved its API price. Unlike Large 3’s Apache 2.0 release, the weights carry a modified MIT license that makes Model-as-a-Service providers obtain a separate commercial license. says 3 more weeks of RL since the preview lifted the model’s Terminal-Bench 4.0 score from 28% to 41%, 1 point above China’s GLM-5.3. On Artificial Analysis’s Coding Agent Index, Large 4 does not lead: its 48% effectively ties GLM-5.3, and its edge is 47% fewer tokens per task. API pricing is now $0.70 input, $0.07 cached input and $2.10 output per million tokens, about half the list prices of $1.36, $0.14 and $4.18 that applied by 22 October with no sale running. The Mistral Ecosystem Open-Weight license lets anyone use, modify and commercialize the model but requires Model-as-a-Service businesses to get a separate commercial license, a tighter deal than the Apache 2.0 license on Mistral Large 3’s open weights.
