This initiative aims to provide a sovereign AI alternative, making its training data, model weights, source code, and alignment principles publicly available and reproducible. Designed with compliance to the EU AI Act in mind, Apertus incorporates features like opt-out respect, PII removal, and memorization prevention from its inception. The model also boasts strong multilingual capabilities, trained on over 1,000 languages with a focus on underrepresented communities, and demonstrates competitive performance against other leading open models.
