ChatGPT Agent
Also known as: ChatGPT agent mode, unified ChatGPT agent
ChatGPT Agent is the result of merging Operator (web interaction), Deep Research (information synthesis), and ChatGPT's general intelligence into one system. Instead of choosing between research mode and action mode, you just describe a goal, and the agent decides how to accomplish it: searching the web, writing code, navigating sites, and producing polished deliverables like spreadsheets or slide decks.
It runs on its own virtual computer and can handle workflows that previously required you to context-switch between multiple tools. OpenAI cited benchmark results where ChatGPT agent performance was comparable to or better than human experts on a range of complex knowledge-work tasks.
For builders evaluating which AI system to use for autonomous task completion, ChatGPT Agent sits at the consumer end of the spectrum, meaning it's optimized for end-user tasks rather than developer-controlled pipelines. The underlying model and capabilities are accessible via API through OpenAI's Responses API and Agents SDK for more programmatic use.
