Sonar Pro

Sonar Pro - Advanced Search Model for Deep Web Retrieval

Sonar Pro is Perplexity’s premium search model for complex research queries. The official docs position it as a search-augmented model that retrieves more sources per query and returns citation-rich answers.

Core Design

Perplexity describes Sonar Pro as sharing the same foundational search-augmented architecture as Sonar, but with deeper web retrieval across more sources. It is intended for queries that need cross-referencing and broader evidence synthesis.

Operating Pattern

The model keeps the same single-call developer flow as base Sonar, with no external search configuration required. Perplexity notes that web search runs on each inference call, and Sonar Pro simply expands how many candidate sources are gathered and synthesized.
