Concept Sliders is a technique for precisely controlling concepts in diffusion models, implemented through low-rank adapters (LoRA) on top of pre-trained models. It allows artists and users to train directional control over specific attributes using simple text descriptions or image pairs. The main advantage of this technology is its ability to make subtle adjustments to generated images without altering their overall structure, such as modifying eye size or lighting, thus achieving finer control. It provides artists with a new means of creative expression while addressing issues of generating blurry or distorted images.
