Perplexity vs ChatGPT — AI Search vs AI Chat (2026)
Perplexity Computer + Comet + Agent API vs ChatGPT Plus / Pro. Cited answers vs GPT Store plugins, real-time research vs multimodal chat on Sep 2026 facts.
## what it does
tl;dr: Perplexity wins on research with citations, model routing, and the new Computer / Comet product surface. ChatGPT wins on the plugin / GPT Store ecosystem, multimodal (DALL-E, voice), and the cheapest paid row at Plus $20. They are not the same kind of product — Perplexity is an answer engine; ChatGPT is an assistant.

What Perplexity is selling in Sep 2026
- Computer is the consumer surface (research, build, design, code). Pro unlocks Computer; Max raises every limit (10× file uploads, 5× video, Model Council runs).
- Comet is the agentic browser. Pro unlocks; Max gets 10× Agent runs.
- Agent API (replacing Sonar on 27 Sep 2026) charges per invocation:
web_search$0.0025,fetch_url$0.0005, sandbox session $0.03 (≤20-min window). Sonar / Sonar Pro / Sonar Reasoning Pro / Sonar Deep Research are deprecated as of that date. - Model routing is the moat — one bill, many frontier models, pick a preferred model per query.
