Deep Research is a ChatGPT feature that works like a tireless research assistant — give it a question or topic, and it independently browses hundreds of web pages over 5 to 30 minutes, then delivers a structured, cited report summarizing what it found. It launched in February 2025 and is available to all ChatGPT users.
Details
Deep Research is powered by specialized versions of OpenAI's o3 and o4-mini reasoning models, trained specifically for multi-step web research tasks. It plans its own sub-queries, browses and interprets web content, and synthesizes findings into a formatted report with inline citations. On "Humanity's Last Exam" — a rigorous academic benchmark — it scored 26.6%. Pro subscribers receive unlimited use; free users receive five queries per month. As of February 2026, users can restrict Deep Research to specific websites or connect it to internal tools via MCP apps. The feature is also accessible via the API.
