Mistral Large 4 is Europe's trillion-parameter answer to US models that refuse security work

Mistral has unveiled Mistral Large 4, its largest model to date. It has one trillion parameters and was trained in the company's own European data centers. In an independent index, the model makes a big leap forward but still falls well short of the leading closed models. Mistral's main pitch is that it handles security tasks that Claude and GPT-6 refuse to touch.

Mistral has released a public preview of Mistral Large 4 (ML4), nicknamed "le Chonk." The API is available now through Mistral Studio. Model weights are expected to follow at the end of October. According to Mistral, ML4 is a natively multimodal model with one trillion parameters, 49 billion of which are active. On X, the company says ML4 is the best open-weight model from the US or Europe across aggregated benchmarks.

It claims state-of-the-art performance in cyber defense, manufacturing, and finance, and says it beats even closed frontier models in visual grounding. An independent look comes from the Intelligence Index by Artificial Analysis, which aggregates ten benchmarks across different domains. ML4 scores 38 points there. That's a…
