Sonar Reasoning Pro model profile
Evidence snapshot:
Sonar Reasoning Pro is a Perplexity model profile with a 128,000-token context window. The dated catalog snapshot records text, image modalities and interfaces for reasoning controls, text generation, vision, web search pricing.
Note: Sonar Pro pricing includes Perplexity search pricing. See details here Sonar Reasoning Pro is a premier reasoning model powered by DeepSeek R1 with Chain of Thought (CoT). Designed for...
Sonar Reasoning Pro is a reference profile: Perplexity publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Sonar Reasoning Pro is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt.
Sonar Reasoning Pro accepts text and image and returns text. The snapshot records reasoning controls, text generation, vision, and web search pricing as capabilities or interfaces.
The dated reference snapshot lists $2 input and $8 output per million tokens.
No comparable third-party benchmark value is present in the 2026-09-06 snapshot. Missing values are not estimated.
No comparable popularity rank or traffic share is present in the 2026-09-06 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated.
Profile data was reviewed for the 2026-09-06 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated.

When to pick Sonar Reasoning Pro
Sonar Reasoning Pro is a reference profile: Perplexity publishes it, Kendr documents it for comparison, and it carries no Kendr alias to call.
Each condition below is derived from this model's own values in the 2026-09-06 snapshot, compared only against models publishing the same field.
- Reach for it when the input includes images. The snapshot records image input, so screenshots, scans, and diagrams can be sent directly instead of described.
- Look elsewhere when you need to call it through Kendr today. This is a research reference profile with no Kendr alias. The facts and evidence here are published for comparison; the model is not routable on Kendr.
- Look elsewhere when the prompt is long. The 128K-token context window is in the bottom quarter of the 163 models publishing a limit. Long documents need chunking or a wider-context route.
- Look elsewhere when you are building an agent. No tool-calling capability is recorded for this model in the snapshot. Agent loops need a route that can call functions.
