ChatGPT's Deep Research tool can create reports from hundreds of online sources

Following the release of o3-mini, OpenAI announced on Sunday Deep Research, a new agentic tool for ChatGPT.

“Our ultimate aspiration is a model that can uncover and discover new knowledge for itself,” said Mark Chen, chief research officer at OpenAI, during the company’s reveal livestream. As far as limitations go, OpenAI says ChatGPT can sometimes hallucinate facts or make incorrect inferences when conducting Deep Research, though “at a notably lower” rate than other current models. In turn, that will allow the company to offer “significantly higher rate limits.” In the meantime, OpenAI hopes to get the tool in the hands of Plus users “in about a month,” following a round of safety testing.
