What is deep research?

Deep research is an AI assistant mode that plans its own research, runs many web searches, reads the pages it finds and writes a report with citations. It takes minutes instead of seconds and suits questions that need several sources, such as a market map, competitor list or salary check.

In one line

An assistant mode that runs many web searches on its own and writes a cited report, useful for market maps, company research and salary checks. Read the sources it cites before you rely on it.

A normal chat answers from what the model already knows, sometimes with one quick search. Deep research works more like a junior researcher. It breaks your question into parts, searches for each, follows links, compares what it finds and then writes a structured report with sources listed at the end.

The output looks polished, and that is the risk. The model can misread a page, cite a stale article or blend two companies with similar names. The citations are there so you can check the claims that matter, and you should.

For recruiting, deep research is strongest on questions with public answers: which companies in a region are hiring a certain skill, who the competitors of a target client are, or how a market has shifted over the past year.

Why it matters to recruiters

Agency recruiters and sourcers spend hours on background work before a search starts. Deep research cuts that time and gives you a starting map of companies, titles and talking points. It is a first draft for your judgment, not a finished answer to send to a client.

An example from a recruiting desk

Before pitching a medical device client, an agency owner asks deep research to list device makers within 50 miles that have posted quality engineering roles in the last quarter. The report names 18 companies with links. She spot checks six, finds two that have since closed their sites, removes them and uses the rest to build a target list.

Tips that help

  • Write a clear brief with location, time frame and what a good answer includes.
  • Open and read the sources behind any fact you plan to repeat to a client or candidate.
  • Ask for a table of companies with source links so checking is quick.
  • Use it for public information only and never paste confidential client or candidate data into it.

Mistakes to avoid

  • Forwarding the report to a client without checking the cited pages.
  • Treating salary figures from the report as current without confirming the date and source.

Frequently asked questions

How is deep research different from a normal AI chat?

A normal chat answers quickly from training data or one search. Deep research runs many searches over several minutes, reads the results and writes a longer report with citations. It is slower but better for questions that need several sources.

Can deep research find candidates for me?

It can point you to companies, teams and public profiles worth a look, but it is not a sourcing database. Use it to build a target company list, then use your sourcing tools to find and contact people.

Are deep research reports accurate?

Often, but not always. The model can misread pages or cite outdated ones. Treat the report as a draft and confirm any fact you will act on by opening the source it cites.
