When to use Sonar Pro
Where this model earns its cost — and where it doesn't.
Sonar Pro integrates live search directly into its generation pipeline. It performs multi-step queries to retrieve current information and returns detailed answers with explicit citations. The model accepts text and image inputs and outputs text only.
On Kyma, it runs with a 200,000-token context window and an 8,000-token maximum output. It does not support function calling, structured outputs, or reasoning traces, and it operates at a medium speed tier. It is classified as a premium tier model, and each request incurs a per-request search fee on top of standard token costs.
Kyma handles routing with automatic failover and includes exact request costs in the usage.cost field. Prompt caching is supported, and cached input prefixes are billed at 10% of the standard input rate. The X-Kyma-Model header confirms the active model for every response.
Deep web research
Query complex topics and retrieve synthesized answers grounded in live sources.
Current events analysis
Track recent developments and generate summaries based on up-to-date reporting.
Long-form cited reports
Draft detailed documents with inline citations and multi-step information gathering.
Image-assisted research
Analyze uploaded images alongside live web queries to contextualize visual data.
Not ideal for: Do not use this model for low-latency conversational chat, function calling, or tasks requiring strict JSON formatting.
