Mistral Releases Weights for Mistral Large 4 to Target Cyber Defense

Mistral releases the weights for Mistral Large 4, a trillion-parameter open-weight model available on Hugging Face and through its API, letting businesses and governments run it on their own systems for cyber defense. Mistral says the model uses 47 percent fewer tokens per task than GLM-5.3 and outranks other open models on Artificial Analysis' Coding Agent Index.

• Mistral CEO Arthur Mensch says AI should "be a tool for empowerment, not dominance."
• Vice President of Science Pierre Stock says open weights give access that "can't be cut off by definition."
• Stock says organizations can run the model on-premises to "identify, coordinate, and respond in real time to major security incidents."
