About this API

Sonar Deep Research is a research-focused model designed for multi-step retrieval, synthesis, and reasoning across complex topics. It autonomously searches, reads, and evaluates sources, refining its approach as it gathers...

Provider-supplied description, not an independently validated performance claim.

These are the catalogue’s token tariffs. Image, audio, video, search and other charges may use different billing units. Zero token rates alone do not mean those services are free. See the complete pricing fields below and the source model page.

Pros and useful characteristics
  • The published 128,000-token context window can accommodate larger inputs, subject to gateway limits.
  • No separate per-request fee is listed in this catalogue observation. Other modality charges may apply.
Cons and practical limits
  • Published input token pricing is above the median of catalogue entries with the same output modalities and known tariffs.
  • Published output token pricing is above the same-modality catalogue median.
  • Trident Protocol currently limits requests to text content, 24 KB of conversation and at most 4,096 output tokens. Free variants remain subject to upstream rate limits and availability.
  • No independent latency, uptime, reasoning-quality or coding benchmark has been measured by this application.

Assessment uses published fields and unweighted price medians across 426 entries with the same output modalities and known tariffs. It is a cost-and-capability comparison, not a quality ranking or recommendation.

Complete published pricing

Source fields are retained exactly, including extra charges and tier overrides. Negative values indicate variable pricing, not rebates. An absent field is not evidence that a service is free.
