# Codex CLI

> Use models provided through ApiGo in Codex CLI for AI coding.

## Install Codex CLI

Install Codex CLI globally with `npm`:

```bash theme={null}
# Version 0.57.0 is recommended
npm i -g @openai/codex@0.57.0
```

## Configure ApiGo API

> **Important: clear OpenAI environment variables before use**
>
> Before configuring, clear the following OpenAI-related environment variables so they do not override your ApiGo settings:
>
> * `OPENAI_BASE_URL`
> * `OPENAI_API_KEY`
