Fabric now supports using the Codex OAuth flow (use your ChatGPT subscription instead of API keys)

[ksylvan]

As of version v1.4.437, Fabric now supports using the Codex OAuth flow that is officially supported by OpenAI.

This allows you to use your ChatGPT subscription with Fabric. This is provided by a new Codex provider (separate from the API-key-based OpenAI vendor). After updating to the latest version, use fabric --setup to set up Codex.
