Codex in your IDE

LESSONLesson 6 · ~15 min

🎯Goal. Run Codex inside your editor with full file context and the option to offload long jobs to the cloud.

  1. 1Install the Codex extension from the VS Code Marketplace (also Cursor, Windsurf, VS Code Insiders, and JetBrains IDEs like IntelliJ, PyCharm, WebStorm). After installing, Codex appears in your editor sidebar.
  2. 2Give it sharper context with open files, selections, and @file references. Switch models and adjust reasoning right in the panel.
  3. 3Offload longer jobs to a cloud environment and monitor progress without leaving your IDE — local for quick edits, cloud for the long haul.

✓You'll see. Codex working in your editor sidebar against the files you have open, with a long task handed off to the cloud.

💳Cost. The IDE extension uses the same plan and usage as the CLI — no separate charge for running it in your editor.

💡Takeaway. The IDE extension gives Codex your editor's context and a one-click path to push long tasks to the cloud.
