The Open Source Initiative (OSI) has introduced a new definition for open-source AI to clarify its principles and guide policymakers. This definition emphasizes transparency, accessibility, and user rights, including the ability to modify and share AI models. While some criticize it as overly strict, others view it as a balanced compromise between ideals and practicality. The OSI plans to enforce these guidelines and release a list of models that comply with the criteria, aiming to standardize open-source AI practices.
