Direct answer
The original ChatGPT agent is no longer available. OpenAI’s Help Center directs readers to ChatGPT Work for longer, multi-step tasks and finished deliverables. A September 7, 2026 reply from an account identified as OpenAI Support also said the old Agent mode had been retired and Work was still rolling out; that forum reply is dated context, not a complete eligibility policy.

For browser-based tasks, OpenAI documents a cloud browser within Work. It is available on paid ChatGPT plans in supported regions, excluding Free and Go, but rollout and workspace permissions can affect access. The guidance reviewed does not list supported countries. (OpenAI Help Center: Using cloud browser in ChatGPT)
For a product or service you operate, OpenAI documents separate developer options: the Agents API, currently in beta, and the Agents SDK. These are developer tools, not documentation of ChatGPT Work itself as an API endpoint. (Agents API FAQ)
Who can access agent-style tasks in ChatGPT?
OpenAI says cloud browser is available in ChatGPT Work on paid plans in supported regions, excluding Free and Go. Availability can vary during rollout and may depend on workspace permissions. The guidance reviewed does not provide a country-by-country list, so don’t infer regional eligibility from an individual user’s report. (OpenAI Help Center: Using cloud browser in ChatGPT)
How to check and try Work
Open ChatGPT on the web or in the mobile app and try starting a task in Work. OpenAI’s guidance supports that starting point, but the material reviewed here does not specify the exact menu, button, or navigation path for finding Work. So this is a way to try Work if it is visible—not a complete account-access check.
If Work or cloud-browser access is absent, the documented eligibility factors to consider are whether the plan is paid (rather than Free or Go), whether the region is supported, whether rollout has reached the account, and—on a managed workspace—whether workspace permissions allow access. The guidance reviewed does not provide a country lookup or a definitive way to distinguish a rollout delay from an account-specific issue. (OpenAI Help Center: Using cloud browser in ChatGPT)
What happened to ChatGPT Agent and Agent mode?
OpenAI’s Help Center says ChatGPT agent is no longer available and points readers to ChatGPT Work. The September 7, 2026 community reply from an account identified as OpenAI Support likewise said the old Agent mode was retired and Work was still rolling out. The forum post does not specify a retirement date, transition details, or which accounts were eligible. OpenAI Help Center: ChatGPT agent · Dated community reply
Older posts and third-party articles about Agent mode—including plan and message-limit claims—should not be treated as current Work eligibility guidance.
Can you use ChatGPT Work through a production API?
OpenAI’s documentation describes Work as a ChatGPT experience and separately documents developer APIs for building agents. The documentation reviewed does not describe ChatGPT Work itself as a drop-in API endpoint. Treat access to Work and API access as separate routes. (OpenAI Help Center: ChatGPT Work and Codex)
For a developer-built application, the documented options include:
- Agents API (beta): OpenAI manages agent sessions and coordination; your application supplies the task, tools, and configuration. Model requests use the selected model’s API rates, and OpenAI tools and hosted sandboxes use their applicable rates. The API currently supports data residency in the United States only. Review the beta’s current terms and technical limits before making it a production dependency. (Agents API FAQ)
- Agents SDK: A code-first approach for cases where your application owns deployment, tools, storage, and approval decisions while the SDK runs the agent loop. OpenAI documents SDK paths for TypeScript and Python. (Agents SDK)
Practical distinction: Consider the managed Agents API if its beta status, managed sessions, and data-residency condition fit your needs. Consider the SDK if you need your own orchestration and runtime controls. Neither is the ChatGPT Work interface exposed unchanged through an API.
