Overview

The Open Source Initiative (OSI) is the nonprofit, formed in 1998, that has stewarded the Open Source Definition for software and, in October 2024, released the Open Source AI Definition (OSAID) 1.0. The OSAID was produced through a multi-year co-design process and defines an OpenSourceAI system by four freedoms plus required access to data information, code, and parameters. OSI validated a short list of compliant models (Pythia, OLMo, Amber, CrystalCoder, T5) and judged Meta's Llama non-compliant. The definition was endorsed by at least 20 organizations including Mozilla, but drew criticism over its treatment of TrainingData — including from OSI co-founder Bruce Perens — and was approved by OSI's 10-person board rather than its full membership.
