In short. ChatGPT may search automatically or use a manually selected Search tool, while answers without search draw on learned knowledge.
Definition: ChatGPT does not always search the web before answering: ChatGPT search retrieves web information, while answers without search draw on knowledge learned during training. As of 17 October 2026, OpenAI documents automatic search when current information would help and a manually selected Search tool.
Key facts
- OpenAI's search help page says ChatGPT may search automatically when a question would benefit from current information.
- OpenAI's accuracy guidance says responses without search enabled draw on what the model learns during training.
- OpenAI's Enterprise and Edu documentation says disabling search for a workspace or role prevents affected users from searching, even when they request it.
When does search run?
OpenAI's Enterprise and Edu documentation describes a conditional process: ChatGPT decides whether current web information would improve a response. When search is available, it can turn the request into queries, retrieve results and produce an answer with source links.
A knowledge cutoff is the point beyond which a model's training data stops covering events. OpenAI's accuracy guidance explains that tools are needed to incorporate information about events beyond that point. Without search enabled, an answer draws on learned information. The same guidance describes Search as a tool for current or niche web information and warns that a model can sound confident while giving an incorrect answer.
How is search selected and indicated?
OpenAI's search help page gives a manual path: open a conversation, select View all tools, choose Search, then submit the question. Entering the following character in the message composer also opens a menu from which Search can be selected:
/
For an existing answer, the refresh control may offer Try again or Search the web.
The same search help page says answers using search may include citations that open their sources. On desktop web, hovering over a citation can preview it. The Sources button can show cited sources and other relevant links. OpenAI's Enterprise and Edu guide also identifies Search in the conversation bar as confirmation of manual selection.
What can prevent search?
The Web search setting lets workspace owners and administrators enable or disable search, according to OpenAI's Enterprise and Edu guide. Available role permissions can also restrict access. Search queries remain subject to plan usage limits.
Some restricted workspace configurations use cached web results or disable search. Cached results are previously stored web content; in those configurations, a search answer can draw on stored results instead of a live search.
OpenAI's accuracy guidance also identifies website access barriers: technical problems, paywalls and site rules in robots.txt can prevent access to relevant information. A request to search a particular page can therefore encounter access limits.

FAQ
How can I ask for a web search?
Select Search before submitting your question, following OpenAI's manual search instructions. You can also use the refresh menu to retry an answer with search when that option appears.
Does a source link make an answer reliable?
OpenAI's accuracy guidance recommends checking references and visiting sources directly when accuracy matters. You can compare the linked page with the claim it is used to support.
