Official description

Learn about Sonar Deep Research for exhaustive research workflows, including pricing and API usage.

Read the official model reference ↗.

Where this model fits

sonar-deep-research is part of the Perplexity API catalog. Its documented modalities are text. Choose it against the request format, output requirements and operational limits of your application.

The source metadata identifies support for search. Confirm endpoint-specific parameters in the official reference before integrating that capability.

The source metadata identifies support for search-augmented. Confirm endpoint-specific parameters in the official reference before integrating that capability.

For a repeatable evaluation, use representative requests, inspect structured output or tool calls, and log latency and usage in your own account. Catalog metadata establishes compatibility; it does not measure answer quality on your workload. Start from the provider guide for authentication and endpoint setup.

Use the exact identifier in Python

This identifier fragment belongs in the authenticated request described in the provider Python tutorial. The tutorial covers the correct SDK, endpoint, environment variable and response shape.

model = "sonar-deep-research"
# Pass model to the provider-specific request in the tutorial.

Frequently asked questions

What is the exact API model identifier?
Use sonar-deep-research exactly as shown in the provider model reference. Display names are not interchangeable with API identifiers.
How much does this model cost?
The current verified prices and billing units are listed in the pricing table above. Cache, batch, tier and region conditions remain separate rows when the provider documents them.
How much input can the model accept?
The model card shows the documented context window and maximum output when available. Your request must leave room for both input and generated output, including any provider-specific reasoning allocation.
Can I use a free tier?
Check the linked provider free-tier page for eligibility and account conditions. An account credit or temporary trial does not establish a permanent free rate.
Where do these model facts come from?
Official provider references are linked beside the data and in Sources. Changes are recorded with observation times; unresolved or undocumented fields are left unavailable.
