Apertus is a public large language model, developed by the Swiss AI Initiative (a collaboration between EPFL, ETH Zurich, and the Swiss National Supercomputing Centre).[1] It was released on September 2, 2025,[2] under the free and open-source Apache 2.0 license.[3]
Designed initially for business and research use cases around the world,[4] Apertus was trained on over 1800 languages, and comes in 8 billion or 70 billion parameter versions and is available on Hugging Face for download.[5][6] The model was developed aiming to adhere to European copyright law, and is one of the first examples of AI as a public good in the vein of AI sovereignty.[6][7][8] It is also the first large model to comply with the European Union's Artificial Intelligence Act.[9][7] At its launch, the model creators emphasized multilinguality, transparency, and auditability as priorities in contrast to commercial frontier model.[10] While international reception was largely positive[11], the first iteration was significantly behind the capabilities of frontier models[4] and needs adaptation for many use cases with chatbots being a secondary but not a primary use case.[5]
