I just launched the Agentic Search Index, a public benchmark of the web-search tools AI agents use. Perplexity Sonar came last of the nine tools tested.

I ran the same Claude agent on 121 web-search tasks through every tool, three times for a total of 3,537 runs.

The site has the full results: the overall ranking, task-type breakdowns, all-in cost per successful answer, latency, failures, confidence intervals, and methodology.

Agentic Resource Radar puts every provider through the same test, so the results are directly comparable. Search is the first index; memory and second-brain tools are next, followed by lead enrichment tools.
