plus $6/$10/$14 per 1,000 requests by low/medium/high search-context size — the same request-fee schedule as Sonar Pro

stated on the model's own page; not restated since the model page became the migration guide on 2026-09-27

Watch out

Sonar Chat Completions support ended on 2026-09-27. The Agent API has no Sonar Reasoning Pro model — Perplexity's migration guide maps it to the `low` preset — and asynchronous requests are no longer supported. Synchronous and streaming calls keep working while they are reformulated as Agent API requests, rolling out by model, and Perplexity does not say at which rate. The price shown is the Chat Completions rate the pricing page still lists

What we would use it for

A reasoning-capable grounded tier between Sonar and Sonar Pro

What this has cost, week by week

Output price at each refresh since 2026-08-20. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.
