Paris-based Mistral releases "Le Chonk," a strong coding model that still trails China overall

Mistral released the weights of Mistral Large 4, nicknamed "Le Chonk," a roughly one-trillion-parameter multimodal model (52 billion active per step) that it says leads open models on coding, scoring 41 percent on Terminal-Bench 4.0 and 19.7 percent on FrontierCode 2.0 while trailing Claude Opus 5.5. Independent testing by Artificial Analysis put the final version at 26 points on its Intelligence Index, behind Chinese open models DeepSeek V4.1 Flash and GLM-5.3 at 32 and MiMo-V2.6-Pro at 30, though it is fast at 161 tokens per second and cheaper per task than the preview. The model is under a modified MIT license requiring a separate license for commercial cloud hosting, and API pricing is $0.70 per million input tokens and $2.10 per million output tokens.
