In late summer 2025, a publicly developed large language model (LLM) will be released — co-created by researchers at EPFL, ETH Zurich, and the Swiss National Supercomputing Centre (CSCS). This LLM will be fully open: This openness is designed to support broad adoption and foster innovation across science, society, and industry. A defining feature of the model is its multilingual fluency in over 1,000 languages.
