Sonar Reasoning Pro API Pricing
Retired September 27, 2026: Perplexity ended Sonar Chat Completions support on that date. Synchronous sonar-reasoning-pro requests are being reformulated as Agent API requests, rolling out by model, and asynchronous ones are no longer accepted; Perplexity's suggested starting point is the Agent API low preset. The rates below are the last the Sonar API listed, kept for invoice checks. Sonar Reasoning Pro was the reasoning Sonar tier for web-grounded problem solving. The Sonar API listed it at $2/M input and $8/M output, with request and search fees billed separately. Checked against Perplexity's migration guide.

This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.
