Mistral says its AI model Le Chonk has overtaken China in the open-weight race

Mistral says its trillion-parameter model Le Chonk has become the world's best open-weight model in automated programming and cybersecurity, matching or surpassing models from Chinese labs such as DeepSeek and Z.ai. The model was trained on cybersecurity and programming problems of increasing difficulty, and the final version is now freely available. Security company Sophos cautions that open-weight models can be misused, and any advanced model could go out of control without careful oversight.
