文本到图像生成的少步蒸馏：实用指南

摘要

扩散蒸馏技术已显著加速了类别条件图像生成，但其在开放式文本到图像生成中的适用性仍不明确。我们首次系统性地研究并比较了前沿蒸馏技术在强效T2I教师模型FLUX.1-lite上的适配效果。通过将现有方法纳入统一框架，我们揭示了从离散类别标签转向自由文本提示时出现的关键障碍。除深入的方法论分析外，我们还提供了关于输入缩放、网络架构和超参数的实用指南，并同步开源实现代码与预训练学生模型。本研究为在实际T2I应用中部署快速、高保真且资源高效的扩散生成器奠定了坚实基础。代码详见github.com/alibaba-damo-academy/T2I-Distill。

Diffusion distillation has dramatically accelerated class-conditional image synthesis, but its applicability to open-ended text-to-image (T2I) generation is still unclear. We present the first systematic study that adapts and compares state-of-the-art distillation techniques on a strong T2I teacher model, FLUX.1-lite. By casting existing methods into a unified framework, we identify the key obstacles that arise when moving from discrete class labels to free-form language prompts. Beyond a thorough methodological analysis, we offer practical guidelines on input scaling, network architecture, and hyperparameters, accompanied by an open-source implementation and pretrained student models. Our findings establish a solid foundation for deploying fast, high-fidelity, and resource-efficient diffusion generators in real-world T2I applications. Code is available on github.com/alibaba-damo-academy/T2I-Distill.
