What is ChatGPT Agent and How Does It Work
ChatGPT agent is an autonomous AI mode that performs multi step tasks without requiring you to guide every step. Unlike standard chat where you ask a question and get an answer, the agent plans a sequence of actions, executes them, and delivers a finished result. It can browse the web through a virtual browser, run code in a terminal, access connected apps like Google Drive and Slack, and create documents, spreadsheets, or presentations. OpenAI launched the agent system card in July 2025, describing it as a model that combines deep research capabilities with operator style task execution. As of mid 2026, agent mode is accessible primarily through the Work experience in ChatGPT. The underlying model is in the same family as OpenAI o3, giving it strong reasoning and planning abilities.
How to Access ChatGPT Agent Mode (Step by Step)
Accessing ChatGPT agent mode takes only a few seconds. On the ChatGPT web or mobile app, look for the experience toggle at the top of the screen. Select Work from the dropdown menu. If you are on the desktop app, open ChatGPT, choose ChatGPT from the top left menu, then select Work from the toggle. You can also type /agent in the composer to activate agent mode directly. Once Work is selected, describe the task you want completed. The agent will begin executing and pause for clarification or confirmation when needed. Agent mode is available on Plus, Pro, Business, Enterprise, and Edu plans. Free plan users do not have access to agent mode. For Enterprise and Edu workspaces, workspace owners must enable agent mode through the permissions settings, and it defaults to off.
How to Use ChatGPT Agent for Research and Web Browsing
ChatGPT agent excels at research tasks that require gathering information from multiple sources. To use it for research, start a Work chat and describe the research question or topic. The agent will launch a virtual browser, visit relevant websites, take screenshots of pages, extract information, and compile a report with source links. For example, you can ask the agent to research the top competitor pricing strategies in your industry and deliver a comparison table. The agent will search for each competitor, visit their pricing pages, and present the findings in a structured format. All outputs include source links or screenshots so you can verify the information. The agent can also access connected apps like Google Drive to incorporate your existing documents into the research. This makes it useful for market analysis, academic research, competitive intelligence, and content planning.
How to Use ChatGPT Agent for Document Creation and Data Analysis
Beyond research, ChatGPT agent can create finished documents, spreadsheets, and presentations. Upload a dataset or paste a link to a Google Sheet, describe the analysis you want, and the agent will use its terminal tool to run code, perform calculations, and generate the output. You can ask the agent to create a quarterly business review deck with charts, a market analysis report with data from multiple sources, or a budget spreadsheet with formulas. The agent writes the code, runs it, and delivers the final file. On the desktop app, the agent can also access local files with your permission, allowing it to work with data stored on your computer. This capability makes ChatGPT agent a powerful tool for data analysts, marketers, and operations teams who need to produce regular reports and deliverables.
How to Use ChatGPT Agent for Task Automation and Scheduling
One of the most powerful features of ChatGPT agent is the ability to schedule recurring tasks. After the agent completes a task, click the clock icon to set it to repeat daily, weekly, or monthly. You can manage all recurring tasks at chatgpt.com/schedules. This is useful for weekly competitive analysis reports, daily market monitoring, monthly content creation, or regular data processing. The agent runs on the scheduled time and delivers updated results. You can review, edit, pause, or delete tasks from the schedules page. Note that each scheduled task invocation counts against your monthly message limit. For businesses, this feature alone can replace multiple manual workflows and save significant time each week.
How to Use ChatGPT Work for Long Running Multi Step Tasks
The Work experience in ChatGPT is the primary interface for agent style tasks. Unlike Chat which is designed for fast conversational questions, Work is optimized for tasks that take minutes or hours to complete. Work can run once, repeat on a schedule, or monitor for changes. It supports all the same tools: web browsing, code execution, file uploads, and app connectors. Work chats sync across web, mobile, and desktop. On the desktop app, Work can also access local files. Work follows the same usage structure as Codex, with message limits determined by your plan. For Plus and Business users, the limit is 40 messages per month. For Pro users, it is 400 messages per month. Work is designed to be the go to mode whenever you need a finished deliverable rather than a quick answer.
ChatGPT Agent Plans and Pricing Compared
ChatGPT agent mode is available on all paid plans. Plus and Business plans include 40 agent messages per month. Pro plans include 400 messages per month. Enterprise and Edu plans also offer 40 messages per month but can use flexible pricing for additional credits. Free plan users do not have access to agent mode. Only initial user initiated agent requests count toward the limit. Intermediate clarifications, authentication steps, and follow up questions within the same agent session do not count against the limit. Each unique agent invocation, including scheduled tasks, counts against the monthly limit. Businesses using the flexible pricing model pay 30 credits per agent message. For most users, the Pro plan offers the best value if you plan to use agent mode regularly.
How to Write Effective Prompts for ChatGPT Agent
Writing good prompts for ChatGPT agent is different from writing prompts for standard chat. Be specific about the outcome you want. Instead of saying "research the market," say "research the top 5 competitors in the project management software space and create a comparison table with pricing, features, and user ratings." Include any constraints, such as the sources you want the agent to use or the format of the final output. Add reference files or links to existing documents. Specify review criteria so the agent knows what quality looks like. Avoid vague or open ended prompts like "check my email and handle everything." The more specific your instructions, the better the agent can plan and execute the task without needing to pause for clarification. You can also interrupt the agent mid task to change direction or add new requirements.
ChatGPT Agent Safety and Best Practices
ChatGPT agent includes multiple safety layers, but it is important to use it responsibly. The agent can access sensitive data when signed into websites or enabled apps. Avoid typing passwords or private information directly in messages. Use takeover mode for sensitive inputs. Enable only the apps needed for the current task. Review the agent output before taking actions based on it. The agent has a watch mode that requires user supervision on certain sites. If something seems suspicious, stop the task immediately. Clear remote browser data after sensitive sessions. Regularly review and manage app permissions in your settings. The agent incorporates prompt injection monitoring and refusal patterns for disallowed tasks, but no system is perfect. Your oversight is the most important safety layer.
"ChatGPT agent incorporates multiple safeguards, including user confirmations for high impact actions, refusal patterns for disallowed tasks, prompt injection monitoring, and a watch mode requiring user supervision on certain sites." (OpenAI, ChatGPT Agent Help Center, 2026)
