arXiv:2602.11146v2 Announce Type: replace-cross Abstract: Preference optimization for diffusion and flow-matching models relies on reward functions that are both discriminatively robust and computationally efficient. Vision-Language Models (VLMs) have emerged as the primary reward provider, leveraging their rich multimodal priors to guide alignment. However, their computation and memory cost can be substantial, and optimizing a latent diffusion generator through a pixel-space reward introduces a domain mismatch that complicates alignment. In this paper, we propose DiNa-LRM, a diffusion-native
The rapid advancement and adoption of diffusion models for generative AI are pushing the limits of current optimization methods, necessitating more efficient and domain-native reward functions.
This development addresses a critical bottleneck in the efficiency and quality of AI model training, potentially accelerating the development of more sophisticated and performant generative AI systems.
The proposed 'diffusion-native' reward modeling technique reduces computational overhead and improves alignment for generative AI, potentially leading to faster training and better outcomes than VLM-based approaches.
