Researchers from EPFL, ETH Zurich, and CSCS have partnered with Swiss company Proton to integrate the open‑source language model Apertus 1.5 into Proton’s AI assistant Lumo. The collaboration allows Apertus developers to receive voluntary, anonymised user feedback from millions of Lumo users, a first for an open model. The partnership also supports Switzerland’s goal of AI sovereignty by providing a competitive, privacy‑focused alternative to foreign chatbots.
