Sonar Deep Research is a research-focused model from Perplexity, engineered for multi-step retrieval, synthesis, and reasoning across complex topics. It autonomously searches, reads, and evaluates sources, refining its approach as it gathers information. This enables comprehensive report generation in domains like finance, technology, health, and current events. The model’s pricing is based on prompt tokens, citation tokens, and the number of searches and reasoning tokens used during its extensive research phase.

Sonar Reasoning Pro is Perplexity’s premier reasoning model, powered by DeepSeek R1 with Chain of Thought (CoT) capabilities. Designed for advanced use cases, it supports in-depth, multi-step queries with a larger context window and can surface more citations per search, enabling more comprehensive and extensible responses. Pricing includes Perplexity search costs for integrated web research.
