ChatGPT Agent Mode — Definition

One-line definition

ChatGPT Agent Mode is the mode of ChatGPT in which the assistant operates as an autonomous agent — planning multi-step work, calling tools, and executing without needing a human turn between each step.

Longer definition

Agent Mode is OpenAI's execution framework that turns ChatGPT from a chat assistant into an autonomous agent. In Agent Mode, the assistant plans a sequence of steps, calls external tools, reads connected data, observes the results, and continues until the task is done or a human needs to intervene. On ChatGPT Business and Enterprise plans, Agent Mode is productized as Workspace Agents — the team-scoped version with admin controls, persistent memory, and scheduled triggers.

In practice

When you see 'ChatGPT Agent Mode' on OpenAI's site or in product UI, it refers to the underlying capability. When you see 'Workspace Agents,' it refers to the productized, team-scoped implementation for business customers. The terms are related but not interchangeable.

Common mistakes

  • Confusing Agent Mode with Custom GPTs — different execution models, different use cases
  • Expecting Agent Mode to work perfectly without prompt tuning — the mode enables autonomy, the prompt determines quality
  • Using Agent Mode for tasks that should be simple chat queries — autonomous execution adds latency and complexity
