GPT-4o Search Preview is built for moments when you need a reliable answer right now. Unlike a standard language model that only knows what it learned during training, it actively looks things up across the web before responding, so you get fresh information about news, prices, scores, releases, and other topics that change quickly.
It's well suited to research-style tasks: comparing products, summarizing recent articles, checking claims, and pulling together facts from multiple sources. Each answer is paired with citations so you can trace the information back to the original page and judge the source yourself.
What makes it distinctive is the combination of natural, conversational writing with grounded, source-backed responses. You don't have to choose between a fluent reply and a verifiable one — you get both in a single turn.
- Researching current events and breaking news
- Comparing products, prices, and recent reviews
- Fact-checking claims with sourced citations
- Summarizing today's top headlines in any topic
- Looking up live data like sports scores or stock prices
Pulls fresh information from the web so answers reflect what's happening now, not just training data.
Includes links to the sources behind each claim so you can verify and dig deeper.
Writes in clear, natural language instead of returning dry search-result snippets.
- Ask for a specific time range, like 'this week' or 'in 2025', to get the freshest results.
- Ask it to compare sources when a topic is controversial so you see multiple perspectives.
- Request citations explicitly with phrases like 'include links' or 'show your sources'.
- Use follow-up questions to refine the search — it remembers the conversation and can dig deeper.
- May occasionally cite sources that don't fully support the claim.
- Cannot access paywalled pages or content behind logins.
- Web results can be uneven in quality and may reflect biases of the sources it finds.

Does GPT-4o Search Preview always search the web?

Can I trust the sources it cites?
Sources are generally reliable, but you should still click through and judge them yourself, especially for controversial or fast-moving topics.
Is GPT-4o Search Preview different from a regular search engine?
Yes — it reads multiple pages, synthesizes them, and writes a tailored answer instead of just listing links.
