Sonar Deep Research API Pricing
Retired September 27, 2026: Perplexity ended Sonar Chat Completions support on that date. Synchronous sonar-deep-research 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 high preset. The rates below are the last the Sonar API listed, kept for invoice checks. Sonar Deep Research was the deep-research tier, with extra citation, reasoning and search-query billing. 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.

Sonar Deep Research API pricing FAQ.
Practical Sonar Deep Research pricing questions, with public list prices separated from assumptions and add-on fees.
Q · 01 What happened to Sonar Deep Research? +
sonar-deep-research the suggested starting point is the Agent API high preset. Perplexity does not say which rates a reformulated request bills at. Its own model on the Agent API, Sonar (Agent API), lists at $0.25/M input and $2.50/M output, with tools billed per call.Q · 02 What is Sonar Deep Research priced at? +
$2/M input and $8/M output on Perplexity's official pricing page, verified 2026-06-14.Q · 03 Is prompt caching priced separately? +
$2/M, instead of inventing a discount.Q · 04 How is the effective price calculated? +
$2.48/M.Q · 05 Does this include every possible fee? +
$2/M, reasoning tokens at $3/M, and search queries at $5/1K. The token calculator is therefore a base estimate, not a full invoice simulator.Q · 06 Are there free trials or production keys? +
Q · 07 Which API model ID should I use? +
sonar-deep-research belonged to the Sonar Chat Completions API, which Perplexity stopped supporting on September 27, 2026. Its suggested starting point is the Agent API high preset; Perplexity's own per-token model there is perplexity/sonar, priced on the Sonar (Agent API) page.
