Researching with ChatGPT

ChatGPT search pulls the latest information from the web directly into the conversation, quickly answering questions that change moment to moment, like current issues, market trends, or competitor activity. Without needing to juggle multiple tabs, you can use up-to-date web data together with the model's summarization and reasoning abilities.

Usage is also simple. Ask a question in a new chat or select Web Search, check whether search was used via the small globe icon next to the response, and click the citation links to review the original sources. Once you get a result, you can immediately refine it with a follow-up prompt like "summarize this into 3 key points."

However, since search results depend on publicly available web material, checking citations is important, and it cannot replace specialized subscription-based research tools or internal company data. In enterprise settings, Workspace Owners may also turn the search feature on or off.

deep research is a feature designed for more complex questions. Instead of simply listing links like a basic search, it goes through multiple stages of finding material, evaluating sources, narrowing queries, and ultimately synthesizing everything into a long, evidence-backed report.

This feature is especially strong for unstructured questions, niche information, and topics that require cross-verifying different sources. Users need to provide detailed input on the topic, goal, timeframe, and required conditions, and if more information is needed, deep research will automatically ask follow-up questions. Processing time can typically take about 5 to 30 minutes.

The key differences are clear.

• Search: suited for questions with a clear scope, like specific facts, documents, or recent information.
• Deep research: suited for strategic, exploratory questions that require weaving together and interpreting multiple sources.
• Speed: Search is fast, on the order of seconds, while deep research is slower but offers depth.
• Output: Search produces short, direct answers, while deep research produces long-form reports with citations and reasoning.

Ultimately, Search is a tool for finding "the accurate information you need right now," while deep research is a tool for "organizing a complex problem into an understandable report." Using the two features depending on the situation lets you get up-to-dateness from search and interpretation and synthesis from deep research.
