Sonar Deep Research Model to synthesize reports with sources and citations
Perplexity Chat and reasoning models Upgrade to use perplexity/sonar-deep-research
This page describes the Sonar Deep Research model (perplexity/sonar-deep-research) and when teams pick it. Use it when you need an exhaustive, citation-backed report that reads like a literature review or market analysis.
What it can do
- Searches the live web and cites sources
- Thinks step by step on hard questions
What people use it for
Market analysis with source list
Ask Sonar Deep Research to scan news, analyst notes and company filings and produce a structured market report with an annotated source list and citations. The output is a single report you can share with stakeholders and a numbered reference section.
Literature review for a white paper
Give Sonar Deep Research a research question and it will gather dozens of academic and public web sources, summarize findings by theme, and include citations for each claim so you can trace facts back to the original papers. This is suited for white papers, grant background sections, and academic overviews.
Technical brief with evidence
Use the model to produce a technical brief that synthesizes benchmarks, standards and vendor docs, with clear citations and a bibliography. Teams use this when they need an evidence-backed recommendation rather than an informal summary.
Why it is worth it
- Combines Perplexity web index with a reasoning model to cite source links.
- Produces long-form, structured reports rather than short answers.
- Includes numbered references and bibliographic details for traceability.
- Handles both news and academic sources for mixed research needs.
Questions people ask
What does Sonar Deep Research do differently from a standard chat model?
It runs an extended research process across many web and academic sources and synthesizes them into a single, citation-backed report rather than giving a short, single-source answer. The model is built for depth and breadth of evidence.
Can it include links and bibliographic references in the report?
Yes. Sonar Deep Research returns citations and reference numbers tied to source links and bibliographic details so readers can verify claims and follow sources.
