Perplexity: Sonar Reasoning Pro

Perplexity Sonar Reasoning Pro is a paid model from Perplexity that accepts text and image inputs across a 128,000-token context window. It supports reasoning, which means it works through multi-step problems before producing a response, but it does not support tool use and structured output support is unconfirmed. These gaps matter if your workflow depends on function calling or reliable JSON output. On price, the model sits at $2.00 per million input tokens and $8.00 per million output tokens, which is a mid-range rate. Its blended benchmark score of 28.5 comes from a single benchmark, so the performance picture is thin and hard to generalize. Buyers who specifically want Perplexity's search-augmented reasoning layer may find it relevant, but anyone prioritizing tool use, structured output, or broad third-party validation should compare alternatives before committing.
