Using LoRA for Efficient Stable Diffusion Fine-Tuning

What changed

Even though LoRA was initially proposed for large-language models and demonstrated on transformer blocks, the technique can also be applied elsewhere. In the case of Stable Diffusion fine-tuning, LoRA can be applied to the cross-attention layers that relate the image representations with the prompts that describe them. We've been testing that pull request since late December, and it officially launched with our diffusers release yesterday.

Why it matters

A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
