VS Code extension

The VS Code extension means the official OpenAI Codex extension in VS Code. It reads the same Codex configuration as Codex CLI and Codex App, so you do not need to configure the SU8 API key, model, or endpoint again in this chapter.

Download the extension

Search for Codex in the VS Code extension marketplace, then install the official OpenAI extension.

Search for and install the official OpenAI Codex extension in the VS Code extension marketplace — Search for Codex in the VS Code extension marketplace, choose the official OpenAI extension, and install it.

After installation, fully restart VS Code. This lets the extension reread your local Codex configuration when it starts.

Configuration

Codex CLI, the VS Code extension, and Codex App use the same configuration method. They read these files from the system user’s home directory:

~/.codex/config.toml
~/.codex/auth.json

To connect the VS Code extension to SU8 Codes, read Codex CLI setup. That page explains how to write the SU8 endpoint, model, and API key.

After writing the configuration, fully quit and reopen VS Code. If the extension still reports errors, first run codex in the terminal to test whether the CLI can connect. If the CLI works, the issue is probably in VS Code extension loading or cache.
