Meta's Muse appears to use an OpenAI model labeled muse-special
I found a model labeled azure/muse-special while Muse was building my website. So I dug deeper.
This is Part 2 of digging through the Muse filesystem after my article hit the front page of Hacker News this week.
In this article I focus on a model I found in my logs called muse-special, and confront the question: does Muse actually use OpenAI and Claude models behind the scenes?
Nearly every session log in my VM was routed to Meta’s internal model, called Avocado.
But one subagent used a model named azure/muse-special.
This made me curious, so I searched across the repo inside Cursor and found this:
“GPT Responses model client via MAGI native Azure OpenAI lane.”
The model catalogue seems to list azure/muse-special then azure/gpt-5.6-sol.
This was different from all the other lines that the Avocado sessions printed (call_ followed by 32 hex characters).
These little details tell me that the muse-special model is possibly an OpenAI model or OpenAI’s Responses API.
