Mistral AI has released the open weights for its trillion-parameter model, Mistral Large 4, nicknamed "Le Chonk." The model is available for download on Hugging Face and features a 1-million-token context window, multimodal capabilities, and multilingual support. A significant change is the new Mistral Ecosystem Open-Weight License, which replaces the previous Apache 2.0 license and includes restrictions on hosted-service use. While Mistral reports strong performance, particularly in cybersecurity, running the model locally is highly demanding, requiring substantial hardware. AI
IMPACT Sets a new precedent for open-weight model licensing and highlights the increasing hardware demands for cutting-edge AI.
