Project to train image generator (LORA?) on networked Pi

I'm interested in playing with this, but I'm not interested in paying $3000
for a high-end nVidia NPU. It seems to be in principle possible to split the
task into smaller subtasks that could be distributed to a Beowulf-style Pi
cluster. Several enclosures exist that let you connect multiple Compute
Modules over a high-speed bus, I hear.

I have minimal experience with Raspberry Pi (not zero, but minimal). I have
none with setting up Beowulf clusters, and none with decomposing machine
learning tasks and distributing them among processors. Thus, I wonder if
there might be an existing project I could learn from and maybe even
eventually contribute to, even if only as a tester.

Thanks.
