arXiv:2606.15048v1 Announce Type: new Abstract: Diffusion models are typically trained with objectives that focus on local denoising targets at individual time steps (or adjacent pairs), which do not enforce consistency between predictions along the denoising trajectory. This lack of cross-time consistency can degrade performance, especially for few-step samplers. We introduce a temporal difference (TD) objective that penalizes inconsistency of the model's multi-step progress along the denoising path. By reformulating the diffusion process as a Markov reward process and casting denoising as a
This research addresses a known limitation in diffusion models, which are a rapidly evolving area of AI, specifically targeting consistency issues that become more pronounced with increased adoption and demand for efficiency.
Improved diffusion model performance, especially in few-step samplers, leads to more efficient and higher-quality generative AI applications, impacting various industries leveraging these models.
The introduction of a temporal difference objective fundamentally alters how diffusion models can be trained, moving beyond local denoising towards trajectory consistency.

More robust and efficient diffusion models will accelerate the development of new AI applications.
The improved efficiency could reduce computational costs for training and inference of generative models, broadening access.
Higher quality and consistency from generative AI may lead to new benchmarks for synthetic content and potentially exacerbate challenges in distinguishing real from fake.
