Deep research

Also: research agent, research mode

In plain words

A feature where the AI searches the web many times and writes a long report with links. Every link still needs checking.

The fuller definition

Deep research is a product feature in which an agent runs many web searches, reads the pages, and compiles a long cited report over several minutes.

Compare the sentence with its source
SOURCE A01

Delivery may be possible in the first week of April, subject to inspection.

UNSUPPORTED SUMMARY

Delivery was promised on 1 April.

The output changes certainty, invents a specific day, and loses a condition. A link to the real source makes checking possible; it does not make that summary accurate.

A concrete example

Asked about a regulatory topic, the feature produces a report with dozens of citations to web pages.

The distinction that matters

The citations point to whatever the agent found online. They are not verified legal authorities, and each one must be checked in the primary source.
