Mistral Unveils New 'Le Chonk' AI Model It Says Rivals Best Open Systems From China

Mistral has unveiled Mistral Large 4, or "le Chonk," a 1-trillion-parameter model that it says is the strongest open-weight AI model developed outside China by a wide margin. The model is entering preview for developers, cybersecurity teams and governments before a broader release later this month. CNBC reports: ML4 was trained on 4,000 Nvidia Grace Blackwell GPUs over two months that were deployed in Mistral's own data centers in Europe. When its core parameters are released, ML4 will rank among the top open-weight models globally on aggregate benchmark performance, Mistral said in a statement. The company added that ML4 was the strongest open-weight model developed outside China by a "substantial margin." The new model still lags behind the frontier in areas such as coding.

"The model capabilities will further improve as we scale up our training capacity, following our Series D fundraise," said Guillaume Lample, co-founder and chief scientist of Mistral. "Further, the cyber defense capabilities will enable enterprises and governments to defend themselves against threat actors that are jailbreaking closed models to perform cyber attacks," he added.
