正文 · 原文
Perplexity has the fastest and most capable Search API, powered by our own Rust-based retrieval and ranking engine, Photon, achieving sub-250ms p95 latency while still ranking highly on relevance and accuracy benchmarks. Photon was built by a small team and hundreds of auto-research loops powered by a more capable internal version of Perplexity Computer. The auto-research loops will help us continually hill-climb on the Pareto frontier to build the fastest and most accurate search infrastructure in the world.
Introducing Fast Search in the Perplexity Search API. Fast Search runs on Photon, our new Rust-based retrieval and ranking service that we built with a small team of engineers and hundreds of agents. It returns 95% of search results in 230 ms or less.在 X 查看被引用的帖子
