ChatGPT Agent

ChatGPT Agent (originally previewed as Operator) is OpenAI's browser and computer-use agent integrated directly into ChatGPT for Plus, Pro, Team, and Enterprise subscribers. It combines a sandboxed visual browser, a text browser, and a terminal environment within a cloud virtual machine to interact with web pages, fill forms, and perform research. Users can guide execution, take over sensitive credential entry, and schedule recurring tasks.
