FreeLLMMistral releases open‑weight 1‑trillion‑parameter model Le Chonk with coding and security gains
Mistral Large 4 (Le Chonk) is now publicly available with three reasoning modes and top open‑weight coding performance.
Mistral announced that the weights for its 1‑trillion‑parameter multimodal model, Mistral Large 4 (Le Chonk), are now publicly released.
The model shows leading results on open‑weight coding benchmarks, scoring 19.7% on FrontierCode 2.0 and 41% on Terminal‑Bench 4.0, while using fewer tokens than competitors.
Three reasoning modes are offered: Low for simple tasks, Medium for everyday use, and High (default) for demanding reasoning, letting users balance performance and cost.
In cybersecurity tests, Le Chonk achieved a 51% score on the Artificial Analysis Cyber Index, indicating strong vulnerability discovery and patching abilities without excessive refusals.
The release follows a public preview that already placed the model at the top of open‑weight coding rankings, and it joins a landscape where the top free chat models are Kimi K3, GLM‑5.3, and MiMo‑V2.6‑Pro.
