Sonar Reasoning Pro

Sonar Reasoning Pro is Perplexity's specialized reasoning model within the Sonar family, designed for complex analytical tasks that require web search integration. As a reasoning-tier model from Perplexity, it combines multi-step reasoning capabilities with real-time web access to provide comprehensive answers to complex questions. The model supports both text and image inputs with a 128K token context window, allowing it to process substantial amounts of information in a single request. Unlike traditional language models, Sonar Reasoning Pro integrates web search functionality directly into its reasoning process, enabling it to access current information and cite sources. However, it does not support tool calling functionality, focusing instead on its core reasoning and search capabilities. Sonar Reasoning Pro is positioned as Perplexity's solution for tasks requiring both analytical thinking and access to up-to-date information. It competes with other reasoning models but differentiates itself through integrated web search, making it particularly suitable for research, analysis, and question-answering scenarios where current information is essential.
