## The Core of ComfyUI-MultiGPU v2:
[^1]: This **enhances memory management,** not parallel processing. Workflow steps still execute sequentially, but with components (in full or in part) loaded across your specified devices. *Performance gains* come from avoiding repeated model loading/unloading when VRAM is constrained. *Capability gains* come from offloading as much of the model (VAE/CLIP/UNet) off of your main **compute** device as possible—allowing you to maximize latent space for actual computation.
## The Core of ComfyUI-MultiGPU v2

1. **Universal .safetensors Support**: Native DisTorch2 distribution for all `.safetensors` models.
2. **Up to 10% Faster GGUF Inference versus DisTorch1**: The new DisTorch2 logic provides potential speedups for GGUF models versus the DisTorch V1 method.
3. **Bespoke WanVideoWrapper Integration**: Tightly integrated, stable support for WanVideoWrapper with eight bespoke MultiGPU nodes.
4. **New Model-Driven Allocation Options**: Two new inutuitive model-driven Expert Modes to facilitate exact placement on all available devices - 'bytes' and 'ratio'

Restore the removed memory-management clarification.

The [^1] footnote was removed from this section. It explains that MultiGPU improves memory management rather than providing parallel processing. Keep this clarification, or replace it with equivalent text.

- **Example**: `cuda:0,0.0207;cuda:1,0.1273;cpu,0.0808` will use 2.1% of `cuda:0`'s VRAM, 12.7% of `cuda:1`'s VRAM, and 8.1% of the `cpu`'s RAM to hold the model.

## 🎯 Key Benefits

- Free up GPU VRAM instantly without complex settings
- Run larger models by offloading layers to other system RAM
- Use all your main GPU's VRAM for actual `compute` / latent processing, or fill it up just enough to suit your needs and the remaining with quick-access model blocks.
- Seamlessly distribute .safetensors and GGUF layers across multiple GPUs if available
- Allows **you** to easily shift from ___on-device speed___ to ___open-device latent space capability___ with a simple one-number change
- Allows **you** to easily shift from ***on-device speed*** to ***open-device latent space capability*** with a simple one-number change

## 🚀 Compatibility

Works with all .safetensors and GGUF-quantized models.

On current ComfyUI builds with DynamicVRAM/comfy-aimdo enabled, MultiGPU keeps DynamicVRAM active on CUDA devices that comfy-aimdo has initialized and falls back to legacy model patching for off-grid MultiGPU CUDA devices. This preserves MultiGPU placement for devices such as `cuda:1` even when comfy-aimdo only initialized the primary device.
