LyCORIS

LyCORIS stands for Lora beYond Conventional methods, Other Rank adaptation Implementations for Stable diffusion.

It introduces a suite of techniques for applying nuanced modifications to a Stable Diffusion model checkpoint, such as modifying the style of an image, injecting a character, or adding an animal, drawing parallels to the LoRA method.

Both LyCORIS and LoRA target the nuanced refinement of Stable Diffusion models, employing a compact, lightweight file for this purpose. They each alter the U-Net by employing matrix decomposition using different techniques.

LoRA represents the original approach, whereas LyCORIS encompasses a range of newer, LoRA-inspired strategies, namely LoCon, LoHa, LoKR, and DyLoRA.
