The Agentic AI Foundation (AAIF), a Linux Foundation initiative, aims to advance open-source agentic AI through vendor-neutral governance, attracting members such as AWS, Anthropic, Cloudflare, Google, Microsoft, and OpenAI. AAIF, co-founded by Anthropic, Block, and OpenAI, oversees projects like the Model Context Protocol, Goose, and AGENTS.md, ensuring they remain open and community-driven. The Linux Foundation's involvement highlights its expertise in maintaining neutrality and fostering collaboration, as seen in its successful management of other open-source projects. Joining as a Silver Member, the Pydantic team, developers of a popular Python data validation library, aligns with AAIF's mission of transparent and collaborative AI evolution. This membership provides access to working groups and community events and enhances collaboration on infrastructure projects like model serving and developer tooling, underscoring the importance of open standards and transparent development in creating robust AI infrastructure.
