The weights of Mistral Large 4 are available on Hugging Face under the Mistral Ecosystem Open-Weight License, a derivative of MIT with restrictions for model-as-a-service. This means you can host the flagship model yourself within the EU or on your own servers, so personal data does not go to an external provider. If you offer the model as a service to third parties, check the licence terms first. source
