Open-source 8-step LoRA for MiniMax H3. Data-free flow self-distillation cuts sampling from 49 forwards to 8, improves camera control, consistency and detail, and keeps H3's joint video+audio output. Weights on Hugging Face; run it with the diffusers loader.
Hey everyone! I'm Yuesong, the researcher behind HyperFlow at Video Rebirth.
Here's why we built this: MiniMax H3 is an incredible video model, but 49 inference steps means long wait times and high GPU costs. We asked ourselves: can we get the same quality in far fewer steps, without any external training data?
The answer is data-free flow self-distillation. The base model teaches itself to compress 49 steps into 8. No extra datasets, no human annotations.
What we got:
2.9× faster on 4×H200 (~60s vs ~175s) 3.0× faster on 1×H200 (~130s vs ~395s) Combined with Sol-Attn, FlashAttention, and VAE parallelism, real-time generation is possible on 8×B200.
Beyond speed, we also improved camera control, temporal consistency, material rendering, and overall balance compared to the base model.

Who hunted HyperFlow?
HyperFlow was hunted by Yuesong Tian. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
