The Swiss AI Initiative is the world's largest open science/open source effort for AI foundation models, started in December 2023. Seeded with over 10M GPU hours on the Alps supercomputer and a 20M CHF grant from the ETH Domain, it is the first initiative of the Swiss National AI Institute—a partnership between the ETH AI Center and the EPFL AI Center—leveraging 800+ researchers (70 AI-focused professors) from 10+ Swiss academic institutions.
