arXiv:2607.06609v1 Announce Type: new Abstract: We propose D2PO (Dynamic Direct Preference Optimization), a principled framework for optimizing diffusion sampling policies with respect to timestep schedules and classifier-free guidance (CFG) weights. Our work is motivated by a fundamental limitation of existing student-teacher regression frameworks; low-NFE student samplers are trained to mimic high-NFEteachers, often sacrificing high-frequency texture fidelity while preserving coarse global structures, thereby misaligning the sampler with perceptual quality. D2PO addresses this challenge by r
The paper proposes a novel optimization framework for diffusion models, addressing a core limitation in current methods by improving perceptual quality at low inference steps, directly relevant to the accelerating demand for efficient AI model deployment.
Improving the efficiency and perceptual quality of diffusion models significantly advances generative AI capabilities, impacting sectors from creative industries to scientific simulation, and accelerating the deployment of these models in real-world applications.
Diffusion models can now be optimized for better perceptual quality even with fewer sampling steps, potentially broadening their applicability and reducing computational costs for high-quality content generation.

More efficient and higher-quality image and content generation becomes accessible to a wider range of users and applications.
The reduced computational overhead allows for the integration of sophisticated generative AI into edge devices or real-time applications.
This could accelerate the development of autonomous creative AI agents, capable of rapidly generating and iterating on complex visual or auditory content.
