Jeff Geerling just did a video with a cluster of 4 Framework Desktop main boards. He put a decent amount of work into Exo and concluded it’s a VC Rugpull… abandoned as soon as it won some attention.

He also explored several other open source AI scale out libraries, and reported that they’re generally way less mature than tooling for traditional scientific cluster computing.
