Mistral releases weights for Mistral Large 4 coding model

Mistral AI has released the open weights for Mistral Large 4, nicknamed Le Chonk, pitching it as a top-tier open coding model offering sovereign control.

Mistral AI has published the weights for an updated model dubbed Mistral Large 4, also known as Le Chonk, making them available on Hugging Face. SiliconANGLE reported that the open-weights release aims to provide organizations with sovereign control over the model, while Reuters reported that the French AI company is also targeting cybersecurity users with the launch.[1][2][3]

The release focuses heavily on software development capabilities. According to reporting by ZDNET's Radhika Rajkumar, Mistral claims Large 4 rivals leading open options such as GLM-5.3 on the Artificial Analysis Coding Agent Index, ranking alongside Codex GPT-6.1 Terra. The New Stack reported that Mistral has called Le Chonk "the best open agentic coding model in the world" and claims the offering is cheaper than those of competitors.[4][5][6][7]
