Perplexity Deep Research

Perplexity Deep Research, launched in early 2025 alongside similar modes from OpenAI and Google, is a consumer-facing autonomous research agent. A single prompt spawns several minutes of browsing — issuing dozens of queries, reading and reasoning across papers, filings, blogs, and news — and returns a multi-thousand-word, cited report with a structured outline. It packages the research-agent pattern into a mainstream UX.

Frequently asked questions

How does Perplexity Deep Research compare to OpenAI's equivalent?

Both spend minutes per query, browse many sources, and produce cited reports. Perplexity emphasizes consumer accessibility and breadth of sources; OpenAI's Deep Research is a ChatGPT Pro feature tuned toward dense analytical depth. Google's Deep Research is integrated into Gemini.

Is Deep Research a separate model?

It's an agentic workflow on top of Perplexity's model (primarily Sonar plus optional frontier models) — the intelligence is in the orchestration, browsing, and synthesis rather than a wholly distinct model.

Can I use it via API?

Perplexity exposes Sonar Pro and Sonar Deep Research via its API, so developers can embed similar research workflows in their own products.
