HyperFlow H3 Flash
A slimmed MiniMax-H3 that makes video with sound on a single 24 GB card
It brings joint video-and-audio generation from data-centre hardware down to an RTX 3090 or 5090, though the weights licence rules out the US, EU and UK.
HyperFlow H3 Flash is Video Rebirth's compressed build of the open MiniMax-H3 model, which generates video and matching stereo audio together. Pruning, low-rank factoring and quantisation bring it near 14B parameters and a handful of sampling steps. A 9 GB GGUF runs in ComfyUI on 24 GB GPUs; a 5-second clip takes about 92 seconds on an RTX 5090. The code is Apache-2.0, but the weights inherit MiniMax's licence, which excludes the US, EU, UK and South Korea without permission.
