OpenSandbox, Anthropic's Agent Skills, and Hugging Face's OpenEv also join AAIF, alongside existing projects like MCP, goose, and AGENTS.md, which launched in December 2025. Open Responses standardizes core LLM primitives like messages and tool calls so developers avoid translating between vendor-specific APIs. AWS Bedrock, Databricks, LM Studio, Ollama, Nvidia, OpenRouter, Red Hat, Vercel, vLLM, and OGC already support the spec. Anthropic is notably missing from the list of supporters, while Google has its own Interactions API. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Open Responses API specification and why was it created? Open Responses is a specification that standardizes core LLM API primitives like messages, tool calls, and function calling across providers. It was created because virtually all LLM providers offer the same building blocks but represent them differently in their APIs, forcing developers to write provider-specific integration code when switching between models. _Developers juggling multiple LLM provider APIs can track standards like Open Responses on daily.dev._ ### Which companies and projects currently support the Open Responses API spec? AWS Bedrock, Databricks, LM Studio, Ollama, Hugging Face, Nvidia, OpenRouter, Red Hat, Vercel, and open source projects vLLM and OGC (formerly Llama Stack) support the spec. Vercel AI Gateway and Databricks Model Serving already implement it. Notably absent are Anthropic, which uses its own Messages API, and Google, which uses its Interactions API. _Teams choosing an LLM integration approach can follow provider adoption of specs like this on daily.dev._ ### What is the Agentic AI Foundation and what projects does it host? The Agentic AI Foundation (AAIF) is a Linux Foundation project launched in December 2025 that provides a vendor-neutral home for agentic AI standards. Its founding projects were MCP, the goose AI agent, and AGENTS.md; it has since added agentgateway and Agent Router, and now OpenAI's Open Responses, OpenSandbox, Anthropic's Agent Skills, and Hugging Face's OpenEv framework. _Developers tracking the agentic AI standards landscape can follow new foundation projects on daily.dev._ ## Similar posts on daily.dev - [Agent Skills: Anthropic’s Next Bid to Define AI Standards](https://daily.dev/posts/agent-skills-anthropic-s-next-bid-to-define-ai-standards-qcfz4gydy) · The New Stack · 2 upvotes · 0 comments --- Tags: [#openai](https://daily.dev/tags/openai), [#mcp](https://daily.dev/tags/mcp), [#anthropic](https://daily.dev/tags/anthropic) [View this post on daily.dev](https://daily.dev/posts/openai-donates-open-responses-its-spec-for-a-common-llm-api-to-the-agentic-ai-foundation-g8na2zwew) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"OpenAI donates Open Responses, its spec for a common LLM API, to the Agentic AI Foundation","url":"https://daily.dev/posts/openai-donates-open-responses-its-spec-for-a-common-llm-api-to-the-agentic-ai-foundation-g8na2zwew","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openai-donates-open-responses-its-spec-for-a-common-llm-api-to-the-agentic-ai-foundation-g8na2zwew"},"datePublished":"2026-10-22T16:07:44.474Z","dateModified":"2026-10-22T18:18:07.631Z","description":"OpenAI is donating its Open Responses API specification to the Agentic AI Foundation (AAIF), a Linux Foundation project.
