A developer successfully ran the video generation model MiniMax H3 locally on a laptop equipped with an RTX 3060 (6GB VRAM) and 32GB of RAM.
- Performance: Generating a 4-second video at 320p took about 345 seconds. While slow, it proves the model can run on entry-level hardware.
- Surprise Finding: The author discovered that H3 can natively generate audio tracks alongside video.
- Workflow: The current ComfyUI workflow pack supports text-to-video, image-to-video, and reference-to-video. This marks a meaningful addition to the local open-source video generation space.
