 # FastH3 VSA-DataFree LoRA + Gate for ComfyUI (experimental)
 Two files that let ComfyUI run **MiniMax H3 video generation in 4 steps** using FastVideo's Video Sparse Attention. On a 24 GB RTX 3090 Ti, this drops a 5-second, 0.8 MP clip from ~8 minutes (base, 20 steps) to under 1 minute (draft) or ~2.5 minutes (best quality). Requires the [companion custom node](https://github.com/barelymining/ComfyUI-MiniMax-H3-FastVideo) — you can't load these with a normal LoRA loader alone.
 > ⚠️ **Experimental.** Tested on one machine (RTX 3090 Ti). Requires the companion custom node — this is not a drop-in for standard LoRA loading. See the node repo before downloading.

+> **Most people should probably use one of the established H3 turbo LoRAs** (e.g. [Comfy-Org's official 4-step turbo](https://huggingface.co/Comfy-Org/MiniMax-H3), [lightx2v's 8-step turbo](https://huggingface.co/lightx2v/Minimax-h3-Turbo)) — they're simpler to set up and don't need a custom node. This project exists for people who want to experiment with FastVideo's sparse-attention approach and see if the speed/quality tradeoff works better for their use case. Compare and pick what you like.
