Are there alternatives to unsloth? I would love to use it but the open/free version only handles one GPU, and it's unclear how much the paid version would cost. I have some limited access to multiple older NVidia cards and would love to make better use of them while I'm still learning. My budget for learning/projects is rather modest. Hopefully they succeed. At work I could make a strong case for going with them as they allow keeping data local only, instead of relying on an API.
