Data-Free Flow Self-Distillation for Few-Step Video Generation — open-sourced a validated implementation on MiniMax-H3 [P]

Excerpt

Hi there, I'm Yuesong, a researcher at Video Rebirth. We open-sourced HyperFlow, an 8-step LoRA for MiniMax-H3. The core idea: data-free flow self-distillation. Diffusers' default sampler does 49 model forwards; we trained a LoRA so the model reproduces that trajectory in 8 steps. The base model is the only teacher — no external dataset, no human labels. Comparisons against base H3 (unedited, same prompts, same seeds) — https://videorebirth.com/lp/hyperflow What we measured: Camera control Tempo
