Mistral AI has launched Mistral Large 4 (ML4), a 1-trillion-parameter model, in public preview.

The natively multimodal model activates 49 billion parameters and targets coding, agentic workflows, visual understanding, science, finance and legal tasks. Trained on 3,800 NVIDIA Grace Blackwell GPUs in Mistral’s own European data centers, its weights are set to be released by the end of October.
