Sonar Reasoning Pro pairs enhanced chain-of-thought reasoning with Perplexity's search-augmented capabilities for demanding analytical workflows. The model works through complex problems with step-by-step inference, emitting a thinking section before its final structured response. It draws on more sources and applies deeper reasoning than non-reasoning variants, returning longer, more logically organized answers suited to research synthesis and informed decision-making. It excels at complex multi-step analysis and strategic decisions where logical structure matters as much as factual grounding. The 128K context window supports extended sessions where prior context informs later reasoning and searches. It is best reserved for problems demanding precision and rigor rather than raw speed. As a thinking model, it does not support image input combined with structured outputs.
