author here. I kept digging through the Muse filesystem after my first post hit the front page here this week.
Going through my logs I found a background agent that used a model called azure/muse-special while building my website. I found this interesting and dug a little deeper.
The transcript and daemon binary point to an OpenAI model running on Azure. Still unclear which one or why it was selected.
The runtime also ships with an Anthropic client and a catalogue listing Claude, GPT and Kimi models. I didn’t observe Claude being used in my own sessions, but this is my Part 2 of exploring the Muse file system.

  Nice work!
  Are you sure this isn't just a custom model that is API-compatible with OpenAI?

    If it's using the same weird (and awful) "backend prompt encryption" pattern and mechanism that Codex also uses (<a href="https://news.ycombinator.com/item?id=48905028">https://news.ycombinator.com/item?id=48905028), then I'd also say it points to OpenAI being involved. Hopefully that shit isn't becoming a more popular pattern, absolutely awful for troubleshooting stuff.

    Anthropic does the same thing with reasoning signatures. It has already become the standard pattern.

    Oh this is like how Mozilla is in every http UA since forever?
