## What it is

ChatGPT Agent is not a separate product but a mode within ChatGPT that activates when tasks require autonomous, multi-step execution. It can browse the web, write and execute code in a sandbox, manage files across sessions, and call third-party tools through integrations — completing work that would previously require multiple guided back-and-forth turns. The same capabilities are exposed programmatically via the OpenAI Responses API with built-in `web_search` and `code_interpreter` tools.

Available on ChatGPT Plus ($20/month), Pro ($200/month), Team, and Enterprise plans. For developers, the Responses API exposes agent capabilities directly, allowing you to build products on top of the same infrastructure ChatGPT itself uses.

<Tip>
  **Use this when** you want a no-setup agentic assistant for knowledge work — research, data analysis, document generation — without building your own agent stack or managing tool integrations.
