Sonar Reasoning Pro
Sonar Reasoning Pro is Perplexity AI's search-augmented reasoning model, combining real-time web retrieval with deliberate chain-of-thought reasoning steps. Unlike standard Sonar models that focus on fast retrieval-augmented answers, this variant applies extended thinking to integrate and critically evaluate retrieved information before generating a response.
It is designed for queries that require both current factual grounding and multi-step logical analysis — for example, comparing recent research findings, evaluating claims against live sources, or planning tasks that depend on up-to-date information. The combination of search grounding and visible reasoning makes it well suited to research workflows where accuracy and auditability matter.
