Mistral releases public preview of Mistral Large 4, a 1T-parameter multimodal model

Why it matters for readers: If you follow AI, this is a major open-model milestone to try via API now and to expect full weights by month-end.

Mistral Large 4 is a natively multimodal model with about 1.05 trillion total parameters and 49 billion active parameters.1 2 4
Mistral is offering a public preview accessible via their API (Mistral Studio) and says it will drop the open weights by the end of the month.2 4
The model was trained from scratch on a cluster of 3,800 NVIDIA Grace Blackwell GPUs in Mistral’s own datacenters in Europe and the preview is served on that infrastructure.2 4
The Mistral API exposes two reasoning levels, “none” and “high,” and the model showed a score of 38 on the Artificial Analysis benchmark, a substantial improvement over Mistral Large 3.4
Mistral describes the model as competitive with top open-source models and highlights strengths in coding, agentic workflows and multimodal understanding.2
