emmanuelvivier · x · 2026-10-12
Mistral's official blog details Mistral Large 4 (le Chonk), now in public preview: a natively multimodal model with 1 trillion total and 52 billion active parameters. Key claims:
- Competitive with the strongest open-source models globally and well ahead of any US/European open-weight model.
- State-of-the-art among open models on enterprise workloads including cybersecurity, finance and law.
- Surpasses even frontier closed models on visual grounding.
- Preview API live on Mistral Studio; weights release by end of month after real-world red-teaming with cybersecurity leaders, vetted partners and state authorities.
A major push for Europe's open-weight camp ahead of the weights drop.
