What is the difference between Linkup and Perplexity Sonar?
- Perplexity Sonar is a consumer chatbot wrapped in an API. Linkup is a search API built for production AI.
- On Verified SimpleQA, Linkup’s Search endpoint ranks first among sub-second web search APIs with a 92% F-score, ahead of Perplexity Sonar Pro, Exa, and Tavily. On SealQA-0, our Research endpoint ranks first across the board with 61% accuracy. The evaluation harness is open source.
- Linkup serves AI agents and pipelines, not end users. The API returns raw context, sourced answers, or structured JSON, depending on what your code needs.
- Linkup partners with premium data providers to keep snippet quality and freshness above what general crawlers return.
