HyperFlow Open-Sources Data-Free Self-Distillation on MiniMax H3 Video Model
kimmonismus · x · 2026-10-20
- HyperFlow is a data-free flow self-distillation technique built on MiniMax H3, now open source.
- How it works: the model generates its own candidate videos, filters them for quality, and self-distills from the passing outputs — no external data or human labels. It's the self-distillation component of their RSI (Recursive Self-Improvement) training paradigm.
- Claims near-full quality at a fraction of inference cost; fast action stays smooth with lighting, smoke and metal detail preserved in busy scenes.
- Supports NVIDIA's Sol-Attn sparse-attention kernel, up to 13% faster H200 generation vs dense attention.
- License: code is Apache-2.0; weights under the MiniMax H3 Community License, which excludes the US, EU, UK and South Korea — check before downloading.
