This ChatGPT feature can build full reports for you

Deep Research is built to create detailed, well-structured reports by gathering information from multiple sources into one organized document.

It now runs on the GPT-5.2 model, which improves accuracy and makes research results more reliable.

You can read full reports directly inside ChatGPT without downloading a separate file.

Reports include a table of contents for easy navigation and a source list so you can quickly verify information.

Users can specify which websites the tool should prioritize, giving you more control over research quality.

You can monitor reports in real time, request edits midway, or add new sources without restarting the entire process.

The feature is currently available for Plus and Pro users, with broader access expected soon.
