VentureBeat reported that Mistral announced a one-trillion-parameter open-weight model called ML4, nicknamed Le Chonk, with a planned public release on October 27. However, Mistral has confirmed none of this information, and the model’s specifications align with an internet meme called Le Chaton Fat. Mistral’s confirmed releases include Small 4, which has 119 billion total parameters with approximately 6.5 billion active, a 256k context window, and Apache 2.0 licensing, as well as Leanstral 1.5, focused on formal verification. In September 2026, Mistral raised 3 billion euros in a Series D funding round, valuing the company at over 21 billion euros, with Samsung leading and participation from a16z and Nvidia.
