Codex CLI Setup

Codex CLI  is OpenAI’s command-line AI coding tool. Since OfoxAI is fully compatible with the OpenAI protocol, you can integrate seamlessly.

Setup Steps

1. Install Codex CLI

npm install -g @openai/codex

2. Set Environment Variables

Codex CLI uses the OpenAI protocol — just configure the environment variables:

export OPENAI_API_KEY=<your OFOXAI_API_KEY>
export OPENAI_BASE_URL=https://api.ofox.ai/v1

Then reload:

source ~/.zshrc

3. Verify Configuration

codex "Create a Hello World Python script"

Tips

Specify a Model

Use environment variables or command-line arguments to specify the model:

# Use Codex default model
codex --model openai/gpt-5.2-codex "Refactor this function"
 
# Use Codex Max (complex tasks)
codex --model openai/gpt-5.1-codex-max "Fix this bug"
