Use Codex CLI with Airoutly

Add Airoutly as a model provider in Codex's config.toml. Codex talks to the Responses API, so pick a model that lists Resp on the models page.

Base URL

https://api.airoutly.com/v1

Key variable

AIROUTLY_API_KEY

Models

Models marked Resp on the models page

1. Install Codex CLI

npm install -g @openai/codex

brew install --cask codex

curl -fsSL https://chatgpt.com/codex/install.sh | sh

powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"

2. Add Airoutly to config.toml

Put your key in the AIROUTLY_API_KEY environment variable, then add the provider to ~/.codex/config.toml (or the folder set in CODEX_HOME):

model = "gpt-5"
model_provider = "airoutly"

[model_providers.airoutly]
name = "Airoutly"
base_url = "https://api.airoutly.com/v1"
env_key = "AIROUTLY_API_KEY"
wire_api = "responses"

3. Choose a model

model in config.toml sets the default. For one run, use codex --model gpt-5-mini. The model must list Resp on the models page.

4. Check that it works

Run codex exec "say hi". The reply should arrive within a few seconds, and the request appears in the console under Usage logs.
