ChatGPT Agent executes full tasks by combining planning, browsing, coding, and document interaction in a single run.
OpenAI’s Agent feature, fully rolled out in July 2025, is one of the most advanced steps in generative AI. Rather than simply responding to prompts with text, ChatGPT Agent actually performs multi-step tasks, accessing tools like a web browser, file reader, code runner, and cloud connectors to carry out operations end-to-end. This mode is available in the same ChatGPT interface under the “Agent” toggle, next to the model selector.
What distinguishes Agent from normal chat is its ability to:
Formulate a step-by-step execution plan before acting.
Perform actions across multiple tools, from web browsing to file editing.
Reason autonomously using a visible "Work Log" with full auditability.
Access and modify files stored in your Google Drive, OneDrive, or Dropbox.
Generate emails, documents, charts, or web content, then send or publish them on your behalf—with human approval at each step.
Agents work within a secure, temporary virtual machine, and run for a maximum of 10 minutes or ~7,000 tool tokens, whichever limit is hit first.
ChatGPT Agent can complete real-world digital workflows with full transparency.
In Agent mode, the chatbot no longer returns a single-text reply. Instead, it thinks aloud, breaks a task into micro-steps, then uses tools one by one to complete it. Each interaction—browser navigation, code execution, file read/write—is logged and visible to the user in a chronological sidebar.
Some current real-world uses include:
The Work Log shows each phase: page loaded, data scraped, code executed, file updated, or email draft created. Users can stop or revise at any step.
The Agent toolbox includes browser control, Python code execution, cloud file access, and secure API calling.
ChatGPT Agent integrates a series of tools designed to cover a wide range of knowledge work. Each tool has strict limits, isolation, and visibility. Here's a breakdown:
Each tool is modular and can be disabled by account admins. For example, some companies disable EmailSend or FileOps for compliance reasons.
Daily limits and pricing tiers control Agent usage.
ChatGPT Agent is available only on paid plans. The number of allowed runs per day depends on the tier:
Every time the Agent is invoked, it consumes a run, regardless of whether the task completes successfully. Admins can view quota usage and reset cycles via the ChatGPT Enterprise dashboard.
Security features ensure safe use of tools and data.
ChatGPT Agent was designed with transparency, containment, and human oversight at its core. Several layers of protection are implemented:
OAuth login prompts mean the Agent never sees your passwords.
No memory is used during Agent runs—everything is ephemeral.
Work Logs show every step, including URL visited, API response, or code output.
Run history can be downloaded as JSON or audited per session.
Sensitive actions (file write, email send, payment, API post) always ask for final confirmation.
Enterprise logs are exportable to security and compliance tools (SIEM, DLP).
Image redaction and screenshot blurring occur after 30 days by default (admin-configurable).
Additionally, Agent will not act on any prompt that attempts prompt injection, phishing, or bypassing its tool policies. Attempts are logged and blocked.
Roadmap features include local PC integration and scheduled automation.
As of September 2025, several advanced capabilities are in development or preview:
This makes Agents not only useful for ad hoc tasks but increasingly powerful for process automation.
Recommendations for productive and safe use of Agent.
OpenAI recommends using Agent as a co-executive assistant rather than as a blind executor. Here are some best practices:
Simulate first: add “simulate” or “dry-run” to prompts the first time to preview behavior.
Review the Work Log before accepting output or sending emails.
Use file-specific instructions, such as “read column C in Sheet ‘Q3Revenue’” to guide behavior.
Build and reuse Agent Recipes for team-wide tasks (e.g., daily report prep).
Set admin policies in Team/Enterprise to limit tool access or external domains.
Avoid running sensitive tasks without testing in isolated docs or sandboxes.
ChatGPT Agent enables task completion, not just information retrieval.
Where the classic ChatGPT interface focuses on text, explanation, and conversation, the Agent introduces execution. This includes collecting data, generating visual content, writing documents, interacting with cloud apps, and performing email or file actions in your stead—without leaving the chat window.
For researchers, analysts, project managers, and content creators, this unlocks a new mode of working: ask, plan, execute—within one workflow. Whether used occasionally for a long task or daily as a part of a business workflow, ChatGPT Agent transforms the assistant into a true autonomous digital coworker, while still leaving human supervision in control.
