OpenAI's Deep Research has more fact-finding stamina than you, but it's still wrong half the time

The latest in generative artificial intelligence includes AI agents that can access the web to find answers to questions. While promising, agentic technology is very much a work in progress. In a paper published last week, OpenAI researchers relate how the company's Deep Research technology, which was built to use the Web, does far better than OpenAI's other models when answering web questions. It also does far better than humans on tasks requiring hours of searching. Also: What are AI agents?
