What is ChatGPT deep research?

ChatGPT's new feature, Deep Research, is designed to conduct comprehensive web-based investigations into any topic by integrating advanced reasoning models with web browsing capabilities. This tool, which OpenAI describes as "agentic," allows ChatGPT to autonomously search the internet and compile detailed reports, although it requires a ChatGPT Plus, Teams, Enterprise, Education, or Pro subscription to access. Deep Research is particularly adept at handling complex queries by breaking them down into smaller steps, which enhances its ability to solve intricate problems, though it may still fall short when it comes to distinguishing authoritative information from rumors. The feature can produce in-depth reports by compiling data from multiple sources, performing statistical analyses, and conducting literature reviews, but its effectiveness is contingent on the availability of reliable online information. While testing has shown that Deep Research can efficiently perform tasks like identifying correlations or summarizing well-documented topics, users are advised to compare its results with traditional web searches for validation.
