Perplexity 发布基于 Rust 引擎 Photon 的 Fast Search API
Perplexity CEO Aravind Srinivas 介绍其 Search API 新增的 Fast Search 功能，底层为自研 Rust 检索与排序服务 Photon，宣称 p95 延迟低于 250ms、95% 搜索结果在 230ms 内返回，同时在相关性与准确性基准上保持较高排名。Photon 由小团队配合数百个由内部版 Perplexity Computer 驱动的 auto-research loop 构建，用于持续在帕累托前沿上优化速度与准确率。
AI推荐理由 Perplexity CEO 披露自研 Rust 检索排序引擎 Photon 及 Fast Search API，给出 p95 延迟低于 250ms、95% 结果在 230ms 内返回等具体指标，并称由小团队加数百个 auto-research loop 构建。属于官方人员一手信息，含可验证的性能数字，对搜索基础设施与 Agent 检索层有参考价值；但延迟与相关性基准的具体测试条件、对比对象未给出，'最快最强'属自我宣称，需保留不确定性。

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.
