OpenAI has released an API for developers to build agents, to include web search, file search, and computer use.

To address these challenges, we’re launching a new set of APIs and tools specifically designed to simplify the development of agentic applications:

The new Responses API⁠(opens in a new window), combining the simplicity of the Chat Completions API with the tool use capabilities of the Assistants API for building agents

Built-in tools including web search⁠(opens in a new window), file search⁠(opens in a new window), and computer use⁠(opens in a new window)

The new Agents SDK⁠(opens in a new window) to orchestrate single-agent and multi-agent workflows

Integrated observability tools⁠(opens in a new window) to trace and inspect agent workflow execution
