Mistral has announced Mistral Large 4, its largest and most capable model yet, nicknamed "Le Chonk".
- Over 1 trillion total parameters, with roughly 49 billion active at inference time
- Handles both text and images (multimodal)
- Mistral claims it is the strongest open-weight model developed outside China, targeting coding, AI agents and cybersecurity
- Preview API is available today; model weights are scheduled to be released on October 27
The author highlights the open-weight release as the key point: another serious model developers can run and customize themselves, arguing the open-weight race needs more contenders and Europe needs more companies building.
