Mistral launches Le Chonk, a trillion-parameter model to rival China

The launch follows a $3.4 billion raise weeks earlier, signaling Europe's bet that open weights can anchor AI sovereignty.

• Mistral released a public preview of Mistral Large 4, nicknamed 'Le Chonk,' a 1-trillion-parameter model, with full open weights expected by October 27.
• Mistral is a three-year-old French lab seen as Europe's top contender against OpenAI and Anthropic, trained from scratch on roughly 3,800-4,000 Nvidia Grace Blackwell GPUs in its own European datacenters.
• The mixture-of-experts model has 49 billion active parameters and is natively multimodal, tuned especially for coding, cybersecurity, finance, and niche verticals like chip design.
• CEO Arthur Mensch says the model beats Chinese rivals on certain benchmarks including cybersecurity, though independent testing by Artificial Analysis placed it between DeepSeek V4.1 Flash and OpenAI's GPT6 Luna.
• The release follows Mistral's €3 billion ($3.4 billion) Series D last month at a €21 billion valuation, led by Samsung, cementing it as one of Europe's best-funded AI startups.
• Before full weights drop, cybersecurity firms and government authorities are getting early access to a version with reduced moderation to red-team its offensive and defensive cyber capabilities.
• The launch frames open-weight models as a sovereignty tool, positioning Mistral as a third path between closed US systems and increasingly dominant Chinese open models.
