Summary

  • OpenAI has released a new Responses API to help developers build AI agents.
  • The Agents SDK also launched to help developers “orchestrate” the workflow of AI agents, making it simpler to manage these agents and ensure they work harmoniously towards a singular goal.
  • The new APIs build on the Chat Completions API, which lets developers create AI tools that respond to customers’ queries, and will replace the Assistants API in mid-2026.
  • The Responses API includes a web search tool replicating ChatGPT’s web search functionality, a tool to search large volumes of documents and a feature to use the Operator model to perform tasks on a user’s behalf.
  • Olivier Godement, head of product for OpenAI, expects developers to use the foundations to create industry-specific agents.
