- On Cognition's private FrontierCode 2.0 benchmark, which assesses end-to-end code quality and whether a repository maintainer would merge the agent's change, Mistral Large 4 leads with a score
- Mistral released Mistral Large 4 (Le Chonk), a 1-trillion-parameter multimodal model, now available with improved coding, cybersecurity, and reasoning efficiency
- Earlier this month, they released Mistral Large 4 (Le Chonk), their flagship 1-trillion-parameter, natively multimodal model, in public preview
Summary
Mistral released Mistral Large 4 (Le Chonk), a 1-trillion-parameter multimodal model, now available with improved coding, cybersecurity, and reasoning efficiency. The team release the weights of Le Chonk, advancing the frontier of open models in agentic coding and cybersecurity. Earlier this month, they released Mistral Large 4 (Le Chonk), their flagship 1-trillion-parameter, natively multimodal model, in public preview. Since then, they've put that feedback to work while continuing to scale reinforcement learning, driving massive improvements in coding and defensive cybersecurity. Mistral Large 4 ranks as the best open-weight model for coding and among the world's most capable open models overall.
