ComfyUI Day-0 Support for MiniMax H3 Cuts VRAM by 66%, Runs on RTX 3060
ComfyUI has officially announced Day 0 native support for the newly open-sourced MiniMax video model. Deep optimizations have drastically lowered the deployment barrier on consumer hardware, enabling smooth execution on standard personal computers.
Confirmed
- Drastic Hardware Requirements Drop: The ComfyUI core team spent months optimizing the model, slashing VRAM usage by 66%. It now runs on a single GPU with 24GB of VRAM, and can even operate smoothly on an RTX 3060 paired with 32GB of system RAM.
- Excellent Consumer-Grade Performance: Community tests show that using 8-bit weights on an RTX 3060, generating a 124-frame video at 832x480 resolution takes less than 10 minutes. The core team also successfully generated a 25-second 1080p video on a consumer-grade GPU.
- Multimodal Generation Capabilities: The model supports text-to-video, image-to-video, and video editing. It can generate clips up to 2K resolution and 15 seconds long with stereo audio. The RunningHub version is now on Hugging Face, supporting image/audio/video-to-video+audio generation (e.g., T2VA, Ref2VA).
- Comprehensive Ecosystem Support: A corresponding ComfyUI node library is now available for developers.
Why it matters
- Breaking Hardware Barriers: The MiniMax video model is inherently massive. ComfyUI's native support and deep optimizations empower ordinary developers to experience and debug multimodal video generation locally without expensive, professional-grade GPUs. This significantly drives the adoption of open-source video models among individual creators.
