Mistral unveils le Chonk, says "significantly outperforms” any open-weight models developed in US or Europe

Mistral announced its newest AI model, Mistral Large 4, or le Chonk, boasting one trillion parameters. The French company positioned this model as the most capable yet, aiming to challenge the leading open-source AI models worldwide. Mistral claimed le Chonk excels in coding, agentic tasks, and handling multiple input types, showcasing "exceptional performance" across these areas.

For critical enterprise tasks like cybersecurity, finance, and law, Mistral declared le Chonk to be the state-of-the-art open model, with some domains like visual grounding surpassing even advanced closed models. The model is currently available for preview to developers and will be fully released later in the month, accessible via Mistral's API.

Mistral, a European competitor to US AI labs Anthropic and OpenAI and cheaper Chinese models, previously raised $3.4 billion in a September Series D round at a $24 billion valuation. The company now also makes third-party models accessible to its clients.
