Agent Skills is open-sourced under Apache 2.0 and CC BY 4.0, already supported by more than 70 agent platforms, with over 1 million skills published and nearly 280 million installs; Open Responses defines shared schemas and streaming events based on the OpenAI Responses API, with implementations already provided by Databricks Model Serving and Vercel AI Gateway.

   OpenAI Donates the Open Responses API Specification to the Agentic AI Foundation

   OpenAI announced that it is donating the Open Responses API specification to the open-source organization Agentic AI Foundation (AAIF), which is part of the Linux Foundation. Open Responses aims to unify foundational LLM primitives such as messages, tool calls, and function calls, reducing the adaptation work developers face when switching between APIs from different vendors. Vercel AI Gateway and Databricks Model Serving have already implemented the specification. AWS Bedrock, Ollama, Hugging Face, NVIDIA, OpenRouter, Red Hat, vLLM and others have also expressed support, while Anthropic and Google continue to use their respective Messages API and Interactions API. Also joining AAIF this time are OpenSandbox, Anthropic's Agent Skills, and Hugging Face's OpenEv framework.
