Sonar Deep Research is Perplexity's most comprehensive research model, built for expert-level analysis that requires exhaustive information synthesis. It runs many iterative web searches across hundreds of sources, applies reasoning tokens for complex analytical thinking, and synthesizes findings into detailed, citation-backed reports. The model autonomously plans its research strategy, evaluates results, and refines its approach before generating structured long-form output. It is purpose-built for academic research, market analysis, competitive intelligence, due diligence, and literature reviews where source accountability and comprehensive coverage matter most. It produces extensive citations and longer, more structured responses than lighter search variants. Because it performs live web searches at inference time, it can access and cite information published after its February 2025 training cutoff.
