About
Environments and Connections are parts of OpenAI's Codex coding agent that determine where tasks run. Codex can work locally (CLI, desktop app, IDE extension) or in the cloud, where reusable cloud environments are set up for each repository. According to OpenAI, cloud tasks keep running when the laptop is closed, and users can follow progress and resume from another device.
Connections, as described by a YouTube reviewer (Matthew Berman), lets a user remotely reach Codex running on their desktop from a phone, paired via a QR code, so a session can continue away from the computer. This detail comes from a creator walkthrough rather than the official pages provided, so exact behavior should be checked in the Codex documentation.
Codex is accessed through a ChatGPT account (Plus, Pro, Business, Edu, Enterprise) or an API key. The Codex CLI is open source under Apache-2.0. Usage limits depend on the plan, and the cloud environment features are part of the hosted service rather than the open-source CLI.
