## Mistral releases open weights
Mistral AI SAS announced open weights for its frontier model Mistral Large 4, nicknamed Le Chonk.
## Model specs
ML4 has 1 trillion parameters and 52 billion active parameters, natively multimodal, and received three weeks of reinforcement training.
## Performance claims
ML4 is one of the best open agentic coding models globally, using 47% fewer tokens per task than top models.
## Training details
Mistral trained ML4 on 3,800 Nvidia Grace Blackwell GPUs in European data centers for high-fidelity tool use and coding.
## Sovereign control
Companies can deploy ML4 on their own hardware within firewalls without exposing sensitive data to the cloud.
## Competitive context
Mistral’s model competes with Chinese coding models like GLM-5.3 from Zhipu and Kimi from Moonshot AI.
## Reasoning modes
ML4 offers low, medium, and high reasoning modes to match task complexity without adjusting prompts.
## Key takeaway

Mistral AI released open weights for Mistral Large 4, its most capable model, to let companies deploy it on their own hardware without cloud exposure.
