The year of 2024 was a busy one for the Open Source Initiative (OSI) as we marched toward the release of version 1.0 of the Open Source AI Definition (OSAID) to ensure that AI systems are innovative and aligned with the foundational principles of Open Source. Our work has revolved around 3 grand areas: licensing and legal, policy and standards, and research and outreach. As the steward of the Open Source Definition, license and legal have been part of our core program since the very beginning of our foundation. We serve as an anchor for open community consensus on what constitutes Open Source. We protect the Open Source principles, enforcing the marks “Certified Open Source” and “Open Source Approved License”. Under policy and standards, we have monitored policy and standards setting organizations, supporting legislators and policy makers educating them about the Open Source ecosystem, its role in innovation and its value for an open future. Lastly, under research and outreach, we are leading global conversations with non-profits, developers and lawyers to improve the understanding of Open Source principles and practice. OSI investigates the impacts of ongoing debates around Open Source, from artificial intelligence to cybersecurity.
