Sonar Pro questions
How much does the Sonar Pro API cost?
$3 per million input tokens and $15 per million output tokens. The estimator on this page turns that into a monthly bill for your own workload.
What is the context window of Sonar Pro?
200,000 tokens of input, and it can write up to 8,192 tokens in one reply. As a rough guide, a million tokens is around 750,000 English words.
Which providers serve Sonar Pro?
8 providers serve it, including Eden AI, Helicone and Kilo Gateway. Prices differ by host, so the Providers table on this page lists each one with its input and output price.
Does Sonar Pro support tool calling?
Not through the standard tools parameter. For an agent that calls your APIs, pick a model from the alternatives below that does.
Is Sonar Pro open source?
No. Perplexity serves it through an API only, so you cannot download the weights or host it yourself.
When was Sonar Pro released?
Jan 1, 2024, with training data up to Sep 2025.
Catalog data from models.dev (MIT licensed), refreshed daily, last on Oct 15, 2026. The summary is written from these facts.
Building on Sonar Pro?
I test your real tasks on it and the two closest alternatives, then ship the agent on whichever wins on cost and accuracy.
