GitHub - kallewoof/tftf: Transforming Transformers -- ultra light-weight pipeline for enormous transformer model manipulation with minimal overhead

Working with large models that don't fit in your VRAM+RAM is extremely annoying when you want to do things like LoRA merging or converting between formats, so I started the tftf (transforming transformers) project.

The idea is simple: do all operations on a per tensor level. Never load "everything" into (V)RAM. This tool is mostly aimed at people who finetune models, especially big models.

Vibe-coded for the most part, but figured I'd post it, since it is probably useful to finetuners.
