arXiv:2510.01184v2 Announce Type: replace Abstract: We present a mechanism to steer the sampling diversity of denoising diffusion and flow matching models, allowing users to sample from a sharper or broader distribution than the training distribution. We build on the observation that these models leverage (learned) score functions of noisy data distributions for sampling and show that rescaling these allows one to effectively control a 'local' sampling temperature. Notably, this approach does not require any finetuning or alterations to training strategy, and can be applied to any off-the-shel
This paper presents a novel technical mechanism to enhance the control over sampling diversity in diffusion and flow models, building on current research trends in AI generation. It reflects ongoing efforts to refine the performance and utility of these sophisticated AI models.
A strategic reader should care because improved control over AI model outputs, particularly in terms of diversity, directly impacts the quality, reliability, and potential applications of generated content. This could make AI systems more versatile and controllable for various tasks.
The ability to control 'local' sampling temperature without retraining diffusion or flow models means greater flexibility and efficiency in deploying these AI systems. This could lead to more tailored and nuanced AI applications in image, text, and other generative domains.
