arXiv:2603.08155v3 Announce Type: replace Abstract: Classifier-Free Guidance (CFG) is a cornerstone of modern conditional diffusion models, yet its reliance on the fixed or heuristic dynamic guidance weight is predominantly empirical and overlooks the inherent dynamics of the diffusion process. In this paper, we provide a rigorous theoretical analysis of the Classifier-Free Guidance. Specifically, we establish strict upper bounds on the score discrepancy between conditional and unconditional distributions at different timesteps based on the diffusion process. This finding explains the limitati
This paper offers a rigorous theoretical analysis of Classifier-Free Guidance (CFG), a core component in modern conditional diffusion models, addressing its empirical nature.
A strategic reader should care because improvements in underlying AI guidance mechanisms directly impact the efficiency, controllability, and practical application of generative AI, particularly in areas like image and content creation.
This research provides a more principled foundation for guiding conditional diffusion models, potentially leading to more stable, predictable, and performant AI systems than empirically tuned methods.
