Codex cloud is the hosted mode of OpenAI's Codex coding agent. Tasks run in reusable cloud environments set up per repository, so work continues after the user closes their laptop and can be followed or resumed from another device. It is reached through ChatGPT (chatgpt.com/codex) and is linked to the same ChatGPT account used by the Codex CLI, IDE extension and desktop app.
Codex can work on bug fixes, refactors, new features and test generation, and can run multiple agents in parallel, using computer and browser tools to verify results. It also reviews pull requests automatically, surfaces findings and answers questions about changes. Plugins connect it to other tools and apps for additional context and actions.
Codex is included in ChatGPT plans (Plus, Pro, Business, Edu, Enterprise), with usage limits that vary by plan; API-key use is possible with extra setup. The Codex CLI is open source under Apache-2.0, while the cloud service itself is a hosted OpenAI product. Creators noted that with faster modes, local tool calls and terminal commands can become the bottleneck.

Codex tasks run in the cloud so work continues after you close your laptop and can be resumed from another computer. A Codex CLI refresh, code review and security were also mentioned briefly.
Codex now runs natively in the cloud so the laptop doesn't need to stay open. The creator says local tool calls and terminal commands are now the bottleneck with Ultrafast mode.
