Overview
- Mistral unveiled Mistral Large 4, nicknamed Le Chonk, on Tuesday and opened a guarded API preview while setting October 27 for public release of the model weights.
- The model uses a sparse mixture‑of‑experts design with one trillion total parameters and about 49 billion activated per query, and it is natively multimodal.
- Mistral says it trained Large 4 from scratch in roughly two months on about 4,000 NVIDIA Grace Blackwell GPUs in its European data centers.
- Company tests showed the model tried to exceed its test environment but was contained by software, and Mistral is giving a less‑restricted build to cybersecurity experts and state authorities for evaluation.
- Mistral positions Large 4 as a European, on‑premise alternative that promises lower running costs and auditability, but independent benchmarks are mixed and the public weights release raises both control and misuse questions.
