Deep Research

AI research reports with citations

Deep Research turns any question into a cited research report by searching and synthesizing multiple web sources in parallel. Cross-references findings, assigns confidence scores, and returns structured intelligence with field-level citations.

Standard web search returns links — you still have to read and synthesize everything yourself. Deep Research does the reading for you. It explores multiple sources, identifies where they agree and disagree, and produces a structured report you can act on. Multiple depth tiers let you trade speed against thoroughness: a quick scan takes under a minute, a full analyst-grade deep dive runs for up to 25 minutes and covers far more ground.

What you can do

  • research — run a deep research job on any topic; choose a processor tier from lite (fast summary) to ultra (analyst-grade deep dive with full cross-referencing)

Who it's for

Analysts, researchers, journalists, consultants, and anyone who needs a thorough answer backed by sources rather than a quick summary. Also useful for due diligence, market research, competitive intelligence, and fact-checking.

How to use it

  1. Use research with a specific, detailed question — more detail gives better results
  2. Choose a processor: pro is the default and handles most research tasks well; ultra for the deepest coverage
  3. Add -fast to any tier name (e.g. pro-fast) for faster results at the cost of some depth
  4. Set output_mode to "text" for a readable markdown report, or "auto" for structured JSON with citations
  5. The tool runs asynchronously — it returns a job ID; poll with get_job_result until complete
Deep Research

Run deep research on any topic. Automatically explores multiple web sources, cross-references findings, and returns structured intelligence with citations. Choose a processor tier to control depth vs speed.

Returns: Structured research findings with field-level citations, confidence scores, and source excerpts. Content is either structured JSON (auto mode) or a markdown report (text mode).

Frequently Asked Questions

How deep can the research go?

You can choose from `lite`, `base`, `core`, `pro`, or `ultra`, depending on how much depth you need.

Does it cite its sources?

Yes. The report includes citations and confidence scores so you can verify the findings.

Can I limit the sources it searches?

Yes. Use `source_domains` when you want to constrain the research to specific websites.

Is the result a report or structured data?

Either. Use `output_mode: "auto"` for structured JSON with citations or `output_mode: "text"` for a markdown report.
