Researchers have identified a critical issue with Classifier-Free Guidance (CFG) in diffusion models, where high guidance levels lead to oversaturation and instability. They propose a novel repair mechanism that replaces the standard CFG formula with a modified version, effectively stabilizing the process without increasing computational cost. This new method demonstrated significant improvements, achieving 9/9 point-FID wins over traditional CFG on tested grids and showing promise in stabilizing high-guidance scenarios for models like Stable Diffusion 1.5.
