How much VRAM does ComfyUI_LocalLLMNodes require?
ComfyUI_LocalLLMNodes requires a minimum of 256MB (0.3GB) of VRAM for base operation. For optimal performance, a GPU with at least 4GB of VRAM is recommended. This node supports low VRAM mode for resource-constrained setups.
Can I run ComfyUI_LocalLLMNodes on an RTX 3060, RTX 4070, or RTX 4090?
✅ RTX 3060 (12GB): Yes, fully compatible with 10.6GB headroom. ✅ RTX 4070 (12GB): Yes, fully compatible with 10.6GB headroom. ✅ RTX 4070 Ti (16GB): Yes, fully compatible with 14.2GB headroom. ✅ RTX 4090 (24GB): Yes, fully compatible with 21.4GB headroom
How much VRAM does ComfyUI_LocalLLMNodes take on an RTX 3060 vs RTX 4090?
On an RTX 3060 (12GB VRAM), ComfyUI_LocalLLMNodes runs smoothly on an RTX 3060 (12GB) with 10.6GB of headroom. This is sufficient to run the node alongside standard SD 1.5 and SDXL workflows in full precision. On an RTX 4090 (24GB VRAM), the node runs with extreme headroom on an RTX 4090 (24GB) with 21.4GB of dedicated headroom. This allows you to combine the node with massive models (like FLUX.1 Dev, Schnell, or Hunyuan Video) in full precision (FP16) without any offload flags.
What PyTorch version does ComfyUI_LocalLLMNodes need?
ComfyUI_LocalLLMNodes requires the following PyTorch-related packages: torch>=2.0.0 # Or a specific version you know works. Ensure your ComfyUI environment has these installed. Ensure your PyTorch installation matches your CUDA version (use torch.version.cuda to check).
What Python packages are required for ComfyUI_LocalLLMNodes?
To run ComfyUI_LocalLLMNodes, you need to install: huggingface_hub, llama-cpp-python>=0.1.0 # Or a specific version, torch>=2.0.0 # Or a specific version you know works, transformers>=4.38.0 # Or a specific version you know works. You can install these using pip or add them to your requirements.txt file.
How can I reduce VRAM usage when running ComfyUI_LocalLLMNodes?
ComfyUI_LocalLLMNodes supports low VRAM mode. To reduce memory usage: (1) Enable --lowvram or --medvram flags in ComfyUI, (2) Reduce batch size to 1, (3) Use fp16 or fp8 precision if supported, (4) Close other GPU applications.
