FreeLLMMistral releases Le Chonk (ML4), a trillion‑parameter open model excelling in coding and security
Mistral's new ML4 model tops open coding benchmarks, offers low‑token usage and strong cyber‑defense features.
On Oct. 6, French AI lab Mistral unveiled Mistral Large 4 (ML4), nicknamed “Le Chonk,” a trillion‑parameter open model whose weights are now publicly available.
ML4 scored 41% on the Terminal‑Bench 4.0 coding benchmark, up from 28% in its preview, and placed a point behind GLM‑5.3 on the overall Artificial Analysis Coding Agent Index with a score of 48 versus 49.
The model runs with three reasoning modes—low, medium, high—and uses 47% fewer tokens per task than comparable open models, according to Mistral.
What it means for you
Le Chonk shows that open models can deliver high coding performance and robust security with far less compute, giving developers and enterprises a cost‑effective alternative to closed services.
