🇨🇭 Sovereign Open-Source AI in Action: Switzerland’s Apertus 1.5 is now integrated into Proton’s Lumo. Starting today, Apertus 1.5 (the open language model built by EPFL, ETH Zurich, and CSCS) is available as an optional model inside Proton’s privacy first assistant, Lumo. ◾️Truly Open Science: Trained on the Alps supercomputer under the Swiss AI Initiative, Apertus is released under Apache 2.0 (8B and 70B sizes). Version 1.5 brings vision capabilities, a 262k context window, a thinking mode, and upgraded tool use. ◾️Sovereignty in Practice: By keeping infrastructure, data, and compute within national borders, Switzerland ensures technological independence from global big tech monopolies. ◾️Privacy by Design: Lumo users can opt into Apertus while maintaining Proton’s zero access encryption. Switzerland is quietly building a blueprint for sovereign, open source AI. Apertus isn't trying to replace every closed system overnight, it's establishing a real, privacy respecting pipeline from supercomputer to consumer application. #SovereignAI #OpenSourceAI #Privacy #SwissAI #ArtificialIntelligence #TechInnovation @cervisiarius @EPFL @TrustValleyCH @LuizaJarovsky @ImanolSchlag @xavierstuder @haeggee @cscsch @AbtSwitzerland @EPFL_AI_Center @DominiqueCAPaul @BrianRoemmele @clara__meister @effi288 @JulienFrrr @AnneLaureBEAUD2 @valentina__py @MLoebekken @alan_frei @ProtonPrivacy @SwissDevJobs @emmanuel_belo @USchuepbach @tagesanzeiger @GH_Wiegand @apertusllm @a_yukh @ETH_AI_Center @ETH @EPFL_AI_Center
