Apertus Launches: Switzerland's Fully Open-Source, Multilingual LLM Breaks New Ground in Transparent AI
EPFL, ETH Zurich, and CSCS have unveiled Apertus—Switzerland's first fully open large language model with unprecedented transparency. The 8B and 70B parameter models, trained on 1,000+ languages including Swiss German and Romansh, release all training data, weights, and architecture under permissive licenses. This landmark project establishes a blueprint for sovereign, ethical AI infrastructure accessible via Hugging Face and Swisscom's platform.
