Perplexity: Sonar Pro Search

Perplexity built Sonar Pro Search as an advanced agentic search system designed to move beyond single-query synthesis. Where traditional models process one prompt and deliver a response, this system plans and executes entire research workflows autonomously using tool use. It represents the most capable iteration in the Sonar family, built to handle complex reasoning and analysis tasks that require structured, multi-step approaches. The system accepts both text and image inputs, making it suitable for visually-informed research and document-heavy analysis. This architectural design positions it as a research engine rather than a simple chatbot.

This model powers Perplexity's own Pro Search mode, meaning the capabilities visible on the platform directly reflect this API offering. The system excels at in-depth information synthesis, autonomous workflow execution, and structured research planning. Practical applications include comprehensive research projects, data analysis, detailed report generation, and complex information workflows. Its autonomous multi-step capabilities make it especially valuable for users who need thorough, structured outputs rather than quick single-turn answers.
