Codex Cloud Reusable Environments Keep Coding Tasks Moving
OpenAI's Codex Cloud uses reusable, published environments that package a repository, tools, dependencies, and access settings. Create the setup on desktop or web, then run isolated coding tasks from desktop, web, or mobile. Tasks can continue while your computer sleeps, subject to plan eligibility and workspace access.
OpenAI introduced reusable Codex Cloud environments at DevDay so developers can prepare a project setup once and reuse it for new coding tasks. An environment combines the repository, tools, dependencies, and access settings Codex needs; each task starts in its own isolated workspace and can continue while your computer is asleep.

Key Takeaways
- Prepare once, reuse the setup. A published environment packages the repository, tools, dependencies, and access settings for future tasks. (OpenAI Help Center)
- Create environments on desktop or web. Once published, you can start and continue eligible cloud tasks from desktop, web, or mobile. (OpenAI Help Center)
- Tasks are isolated from one another. Each cloud task gets its own workspace and separate working files and changes. (OpenAI Help Center)
- Your computer does not need to stay awake. OpenAI says cloud tasks can continue while your computer is asleep. (OpenAI Help Center)
- Check plan and workspace access first. Codex Cloud is not included with Free or Go, and managed workspaces control cloud access. (OpenAI Help Center)
What a Reusable Environment Changes
A reusable environment gives Codex a prepared starting point for a project. Instead of supplying the same repository setup, tools, dependencies, and access settings for each new task, you publish the environment and select it when you delegate work. OpenAI says changes to a published setup apply to new tasks, while existing tasks keep their own state. (OpenAI Help Center)
OpenAI describes Codex Cloud as running on OpenAI-managed computers. Each task starts from the published environment in a separate, isolated workspace, so parallel or follow-up tasks do not share one set of working files. The setup supports practical jobs such as investigating a bug, making a code change, or running project tests. (OpenAI Help Center)
Set Up and Use a Cloud Environment
Create and publish a cloud environment on desktop or web, then choose it for a new task and describe the work. OpenAI's setup guidance covers connecting a repository, preparing and testing the environment, adding credentials, configuring network access, and connecting private services. (OpenAI Help Center)
| Step | What to do | Why it matters |
|---|---|---|
| Connect the project | Add the repository Codex should work in. | The environment needs the project code and required access. (OpenAI Help Center) |
| Prepare the setup | Add the tools and dependencies the project needs, then test the environment. | New tasks start from this published setup. (OpenAI Help Center) |
| Review access | Configure credentials, network access, and private-service connections deliberately. | Access settings are part of the environment, so review them before delegating work. (OpenAI Help Center) |
| Publish and delegate | Publish the environment, select it for a task, and describe the coding job. | Each task gets a separate workspace based on the prepared setup. (OpenAI Help Center) |
The details in the table follow OpenAI's Codex Cloud setup and environment documentation. (OpenAI Help Center)
Where Tasks Run and How to Resume Them
You can start and continue cloud tasks from desktop, web, or mobile after the environment is prepared. The coding work runs on OpenAI-managed computers, so a cloud task can continue while your own computer is asleep. That is different from remotely controlling a task running on your local computer, which still depends on that machine and its access settings. (OpenAI Help Center)
Keep important changes in source control. OpenAI notes that starting a new task creates a separate workspace and does not recover another task's uncommitted changes; commit work you want to preserve, then review the changes and test results before using them. (OpenAI Help Center)
Codex Cloud Plan and Workspace Access
Codex Cloud is available to eligible Plus, Pro, Business, Enterprise, Healthcare, and Education accounts, subject to rollout and workspace settings. It is not included with Free or Go. Guest, K–12, and Enterprise view-only seats are not eligible to create cloud environments. (OpenAI Help Center)
| Plan or account | Codex Cloud access | Source |
|---|---|---|
| Free or Go | Not included | OpenAI Help Center |
| Plus | Eligible accounts, subject to rollout and workspace settings | OpenAI Help Center |
| Pro | All Pro tiers, subject to rollout and workspace settings | OpenAI Help Center |
| Business, Enterprise, Healthcare, or Education | Available subject to rollout and workspace settings | OpenAI Help Center |
| Guest, K–12, or Enterprise view-only seat | Not eligible to create cloud environments | OpenAI Help Center |
In a managed workspace, the administrator controls whether members can use cloud tasks. Enterprise cloud access is off by default for workspaces that have not enabled it. Creating or editing a workspace-shared environment also requires the separate Manage workspace environments permission, which is off by default. (OpenAI Help Center)
When to Use Codex Cloud
Use a reusable cloud environment when you want Codex to start from a known project setup, handle a task while your own computer is asleep, or continue work across desktop, web, and mobile. Keep the environment's credentials and network access scoped to what the task needs, and check that the workspace has enabled Cloud access. (OpenAI Help Center; OpenAI Help Center)
Before merging or relying on generated changes, return to the task, review the diff and test results, and commit important work to source control. A new task gets a separate workspace rather than inheriting uncommitted changes from an earlier task. (OpenAI Help Center)

Codex Permission Profiles: Least-Privilege Controls for Local Agent Work
OpenAI shipped Codex permission profiles in beta -- reusable, inheritable policies that replace the coarse sandbox_mode/sandbox_workspace_write combo. A profile binds OS-enforced filesystem read/write/deny rules (down to **/*.env) to per-domain network and Unix-socket rules. Enterprise admins get fail-closed allowlists via requirements.toml. Profiles govern local sandboxed command execution only, not MCP servers, app connectors, browser, or cloud.

OpenAI Launches dots: Always-On Agents in ChatGPT With Their Own Cloud Computer
OpenAI's dots are always-on agents in ChatGPT, powered by GPT-6 Astra, that keep working between conversations using their own cloud computer and the apps you connect. They are rolling out gradually to eligible Pro users outside the EEA, Switzerland, and the UK and to Business Premium, and usage won't count toward eligible plan allowances for the next month.
Frequently Asked Questions
What is a reusable Codex Cloud environment?
It is a published setup for a project that brings together the repository, tools, dependencies, and access settings Codex needs. You can select that environment for new cloud coding tasks instead of preparing the same project setup each time.
Can Codex Cloud keep working when my computer is asleep?
Yes. OpenAI says cloud tasks run on OpenAI-managed computers and can continue while your computer is asleep. Remote access to a task running on your own computer is different and still depends on that computer and its access settings.
Which ChatGPT plans include Codex Cloud?
OpenAI lists eligible Plus, all Pro tiers, Business, Enterprise, Healthcare, and Education accounts, subject to rollout and workspace settings. Codex Cloud is not included with Free or Go, and some guest, K–12, and Enterprise view-only seats cannot create cloud environments.
Where do I create and publish an environment?
Create and publish the environment on desktop or web. After it is ready, you can start or continue cloud tasks from desktop, web, or mobile, depending on account eligibility and workspace settings.
