# Perplexity

## Description
**Perplexity** is an AI search engine — usable directly via web UI or via API — optimized for low-token research workflows.

## Role in This Source
The speaker strongly recommends using Perplexity for **web research** instead of relying on the native, token-heavy web search tools built into models like Claude or ChatGPT. It is the canonical *Gather Mode* tool in [[concept-gather-vs-focus]] and a core lever in [[framework-clean-conversation]].

## Why It's Cheaper
- Retrieval / scraping happens upstream of the frontier model
- Only the digested answer flows into your main model's context — saving 10K–50K tokens per search
- Perplexity API is reportedly 3–10x cheaper than running native search through Claude/ChatGPT

See [[claim-perplexity-cheaper-faster]] for full numbers and validation.

## Caveats (from enrichment overlay)
OpenAI's SearchGPT/o3 (2026) reportedly closes much of this latency/cost gap on simple queries; the advantage narrows for trivial searches but remains material for complex research.
