Introducing deep research

February 10, 2026 update: You can now connect deep research to any MCP or app and restrict web searches to trusted sites, so you can focus on authenticated, industry-standard sources. You can also now track progress in real-time and interrupt to refine with follow-up prompts or new sources. We've updated the visual experience so it's easier to start, track, and review your research from end to end.

July 17, 2025 update: Deep research can now go even deeper and broader with access to a visual browser as part of ChatGPT agent. To access these updated capabilities, simply select “agent mode” from the dropdown in the composer and enter your query directly. The original deep research functionality remains available via the “deep research” option in the tools menu.

April 24, 2025 update: We’re significantly increasing how often you can use deep research—Plus, Team, Enterprise, and Edu users now get 25 queries per month, Pro users get 250, and Free users get 5. This is made possible through a new lightweight version of deep research powered by a version of o4-mini, designed to be more cost-efficient while preserving high quality. Once you reach your limit for the full version, your queries will automatically switch to the lightweight version.

February 25, 2025 update: All Plus users can now use deep research.

February 5, 2025 update: Deep research is now available to Pro users in the United Kingdom, Switzerland, and the European Economic Area.

Today we’re launching deep research in ChatGPT, a new agentic capability that conducts multi-step research on the internet for complex tasks. It accomplishes in tens of minutes what would take a human many hours.

The ability to synthesize knowledge is a prerequisite for creating new knowledge. For this reason, deep research marks a significant step toward our broader goal of developing AGI, which we have long envisioned as capable of producing novel scientific research.
