OpenAI Codex

Already paying for a Codex subscription? Connect it via OAuth — no API key, no extra cost. Axon routes to it and takes nothing; you're billed by OpenAI exactly as you already are.

:keys set openai connect

This opens a browser window for authentication. Once approved, Codex models appear in the model palette. The connection auto-refreshes — you won't need to reconnect unless you explicitly disconnect.

Keys are stored locally in ~/.axon/ and never sent to Axon servers. Check what's configured any time:

:keys show

Connected? Your First Agent is next.
