OpenAI donates Open Responses API spec to the Agentic AI Foundation

What's Happening

• OpenAI donated its Open Responses API specification to the open source Agentic AI Foundation, according to The New Stack.
• The foundation accepted OpenSandbox, Anthropic's Agent Skills, and HuggingFace's OpenEv framework.
• The Open Responses specification standardizes core API calls like messages and tool calls across different large language model providers.
• AWS, Databricks, Nvidia, and Vercel support the specification, while Anthropic remains absent from the list.

Why It Matters

Developers waste time rewriting code to accommodate different API structures when switching between AI models. A shared standard eliminates this friction and accelerates agent development. Moving the project to a neutral foundation prevents any single vendor from controlling the ecosystem.
