France’s Mistral unveils new open-weight AI model ML4

French AI company Mistral has unveiled its new open-weight AI model, Mistral Large 4 (ML4). The 1trn-parameter model, known as 'Le Chonk', significantly outperforms open-weight models developed in the US or Europe. ML4, which was trained on 3,800 Nvidia Grace Blackwell GPUs in Europe, is the company's largest and most capable model to date.

Trained on multilingual data from over 160 languages, including all EU languages, Mistral claims ML4 excels in critical enterprise workloads like finance, law, and cybersecurity. The model ranks among the top five globally and leads open-weight models outside China on the Artificial Analysis Cyber Index, scoring highest in tests to reproduce and patch real vulnerabilities in open-source software.

Mistral emphasizes the model's ability to perform agentic coding and achieve higher scores in industry benchmarks compared to some Chinese competitors. The weights for ML4 will be released at the end of the month, following feedback collection during a public preview launched yesterday. Mistral's move underscores the push for European AI sovereignty amid a competitive global race for dominance in AI, where open-weight models are gaining prominence.
