OpenAI hands Open Responses, its multi-provider LLM API spec, to the AAIF with AWS backing

Announced Oct 22, the Responses API-based spec now sits under the Agentic AI Foundation next to MCP and A2A, so one request and streaming format can target any provider that implements it; AWS employs a core maintainer, and Vercel AI Gateway and Databricks already support it. On Bedrock you can point the OpenAI SDK at https://bedrock-runtime.{region}.amazonaws.com/openai/v1 to call Anthropic, Meta, Mistral, DeepSeek and other models (The New Stack).
