Perplexity: Sonar Reasoning Pro
Perplexity Sonar Reasoning Pro is a paid text-and-image model from Perplexity with a 128,000-token context window. It supports reasoning, which means it applies a chain-of-thought process before producing a response. It does not support tool use or structured output, so workflows requiring function calling or guaranteed JSON formatting will need a different option. On price, the model sits at $2.00 per million input tokens and $8.00 per million output tokens, placing it in the mid-to-upper tier for cost. Its blended benchmark score of 28.5 comes from only one independent benchmark, so that figure should be treated with caution rather than taken as a settled measure of capability. Buyers who specifically need reasoning support alongside image input may find it worth evaluating, but those prioritizing tool use, structured output, or well-validated benchmark performance have stronger alternatives to consider first.
