This paper introduces Apertus, a large language model developed by the Swiss AI Initiative, a partnership between ETH Zurich and EPFL. The GitHub repository appears to host technical documentation or code related to Apertus, while the Hugging Face page provides a comprehensive overview of the Apertus-8B-Instruct-2509 model. This model is highlighted for being fully open, massively multilingual (supporting over 1800 languages), and compliant with data privacy regulations, even incorporating mechanisms for data protection and copyright requests. The Hugging Face page also outlines the model's technical specifications, how to use it, its evaluation, training details, and limitations.
