ChatGPT Deep Research
OpenAI's multi-step research agent for comprehensive reports
Part of this entry was LLM-drafted and is being polished.
Deep Research is OpenAI's research agent — give it a topic, it autonomously browses dozens of sites, takes 5-30 minutes to compile a structured report with citations. Available on ChatGPT Plus / Pro tiers (limited / unlimited respectively).
Editor's verdict
Most thorough research agent today — depth and citation density beat Gemini Deep Research and Perplexity Pro on typical use. Pro tier ($200) for unlimited; Plus tier got limited Deep Research access. Worth it only if you do real research weekly. Even then, sanity check claims — confidently-presented synthesis can mask weak sources.
