Perplexity 发布 Fast Search：基于 Rust 引擎 Photon 的搜索 API

该服务 95% 的搜索结果在 230 毫秒内返回，p95 延迟低于 250 毫秒。Photon 由一个小团队开发，并借助内部版 Perplexity Computer 驱动的数百个 auto-research 循环持续优化，在相关性与准确性基准上保持靠前排名。

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. Perplexity @perplexity_ai 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. 🔗 View Quoted Tweet📊 21 ⚡
