A developer has tested the extreme rendering speed of the MiniMax H3 Turbo model within ComfyUI. Running on an RTX 5090 (32G VRAM/96G RAM) and optimized with Sage Attention, the results are astonishing:
- 5s 480P video: Rendered in just 28 seconds
- 15s 480P video: Rendered in 160 seconds
- 15s 1K video: Rendered in 6 minutes
The author notes that while this max-acceleration mode sacrifices output quality, the generation speed is incredibly fast. The original workflow JSON file has been shared with the community.
