Pricing
Pricing is based on the number of tokens used. For tool-specific models, like search and computer use, there's a fee per tool call. See details in the pricing page.

Token pricing excludes the per-request search fee of $6/$10/$14 per 1,000 requests for low/medium/high search context size. Perplexity publishes these rates for Sonar Chat Completions, which it supports until September 27, 2026, after which the model moves to the Agent API.
