AI ArXiv
A new distillation study for Qwen-Image-2.0 identifies data composition and teacher guidance as critical, non-obvious factors for achieving high-performance few-step image generation.
What: The authors analyzed factors influencing the 'Qwen-Image-Flash' training pipeline, demonstrating that distillation requires a principled organization of the entire training setup rather than just optimizing the loss function.

  • Few-step distillation: A process where a large, compute-heavy 'teacher' model is used to train a smaller, faster 'student' model to perform a task in very few inference steps.
Original article
Few-step distillation has become an effective strategy for accelerating advanced visual generative models, yet prior work has largely focused on distillation objectives. In this work, we revisit few-step distillation from a complementary perspective, focusing on the training recipe that critically shapes student performance. Using Qwen-Image-2.0 as a representative case, we systematically investigate three factors in unified text-to-image generation and instruction-guided image editing distillation: data composition, teacher guidance, and task mixture. Our empirical analysis reveals several non-obvious behaviors, which motivate the development of Qwen-Image-Flash. Overall, our results suggest that effective few-step distillation requires not only carefully designed objectives, but also principled organization of the broader training pipeline.
