via “sdxl multi-stage refinement with base and refiner models”
Hugging Face's diffusion model library — Stable Diffusion, Flux, ControlNet, LoRA, schedulers.
Unique: Uses denoising_end parameter to split the denoising loop between base and refiner models, enabling staged refinement without separate latent encoding. The architecture supports skipping the refiner stage entirely for faster inference, whereas competitors require full two-stage pipelines or separate inference code paths.
vs others: Two-stage refinement produces higher-quality details than single-stage models; refiner stage focuses on fine details while base model handles composition. More efficient than training a single large model; enables quality/speed tradeoffs by adjusting denoising_end parameter.
