Sonar Deep Research endpoint guide
1 of 1 Sonar Deep Research endpoint currently have the published data required for this ranking. Perplexity leads at 83.32 s via perplexity. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.
The fastest ranking estimates a 500-token answer by adding the recent median first-token wait to 500 divided by median output throughput. It represents an example complete response, not a guarantee for every prompt or request size.
Only 1 route currently qualifies, so the rank alone provides limited choice. Review every visible endpoint for price, speed, uptime, context length, and route-specific configuration.
Sonar Deep Research has 1 published provider option, and performance data is matched to each exact OpenRouter routing tag. Different quantization, context, regional deployment, or provider configuration can change price and behavior even when the underlying model name is identical.
