Connect ChatGPT to a sandbox

Connect the ChatGPT desktop app to a sandbox over SSH so Codex works inside the isolated environment instead of on your host.

Note

This page covers running Codex in the ChatGPT desktop app connected to a sandbox over SSH. To run the Codex CLI inside a sandbox directly, see Codex.

Prerequisites

• SSH access set up. See Editor and app integrations.
• The ChatGPT desktop app installed.

ChatGPT's remote server requires the codex command in the sandbox. The Codex sandbox template used in the following section includes this command.

Connect

Create a named Codex sandbox for the current directory if you don't already have one:

$ sbx create --name demo codex .

Confirm that you can connect to the sandbox from a terminal:

$ ssh demo.sbx

In the ChatGPT desktop app, open Settings > Connections and add an SSH connection manually. Enter the sandbox hostname, such as demo.sbx, as the host, then use the remote folder picker to select the mounted workspace as the remote project.

For more connection options, see the OpenAI instructions to connect to an SSH host.
