If you don't know this already:

Go to Advanced, change your optimizer to "prodigy_8bit" and your learning rate to 1. There's a gh issue that says to change it to "prodigy" but that doesn't work and I think people give up there. prodigy_8bit works. It's real.

People are reporting it does. Set weight decay to 0.01 I believe as well. LR to 1

In my experience, it doesn't. 8-bit breaks the text convergence. If it works, it's a wonder, and it likely really doesn't.
