Mistral releases the weights of its trillion-parameter model Mistral Large 4 (ML4), targeting cybersecurity

Mistral releases the weights of its trillion-parameter model Mistral Large 4, which governments and enterprises can deploy themselves for cyber defense. It can locally detect, analyze and respond to threats to code and IT infrastructure. Mistral says performance is comparable to GLM-5.3, using 47% fewer tokens per task, and that it leads all open-source models on the agentic coding tasks of the Coding Agent Index.
