Mistral releases Le Chonk, a trillion-parameter coding model trained in Europe

Mistral has released the weights for Large 4, nicknamed "Le Chonk," a trillion-parameter model trained entirely in Europe. Mistral says the model beats its open rivals at coding, and independent testing found it fast and fairly cheap. However, it still trails China's top models, scoring 26 points compared with 32 for DeepSeek V4.1 Flash and GLM-5.3.

Why it matters: It is a concrete model release with open weights, coding performance claims, and independent comparisons that help readers gauge Europe's competitive position.
