Meta's Muse appears to use an OpenAI model labeled muse-special

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.

I don't really see evidence that it's an "OpenAI" model, the title is IMO very misleading.

It'd be hilarious that meta chose to pay openai. If there was such a deal, would it come to light in any public/official filings?

Muse 1.3 spark occasionally spits out Chinese character responses to me like internal instructions. “Go fast” or “Get help”…

I'm not sure I understand why they would route it to other models. It can't be that they don't have enough compute. Maybe worried that the answer from their own models would be bad? Doesn't really make sense, but I could be missing something.

I thought it was 1.3 spark. No?

zuck wouldn't do this, he is too proud imho
