At this point I'd consider a cluster of top specced Mac Studio's to be worth while in production. I just need to host them properly in a rack and in a co-lo data center.

Honestly, I genuinely can see the value if you want to host something internally for sensitive and important information. I really hope the M5 ultra with matmul accelerators will knock this out of the park. With the way RAM is trending, a Mac Studio cluster will become more enticing.
