How ComfyUI compares to Rented Cloud GPUs (RunPod / Civitai / Replicate)
Running ComfyUI locally on Windows costs zero per image, keeps prompts and client assets private on your SSD, and avoids cold-boot pod delays.
**Where ComfyUI pulls ahead:** 100% private local files, no hourly billing, instant launch, and persistent 100 GB+ model library on local NVMe.
**Where Rented Cloud GPUs (RunPod / Civitai / Replicate) fits:** Temporary access to 48 GB–80 GB datacenter cards if you have no NVIDIA GPU.
Running both tools on the same Windows PC without duplicating checkpoints
You do not need to delete Rented Cloud GPUs (RunPod / Civitai / Replicate) or duplicate 100 GB of `.safetensors` files to switch to ComfyUI. Configure extra_model_paths.yaml so ComfyUI reads your existing checkpoints, LoRAs, VAEs, and ControlNets directly from disk.
Install the Windows desktop or portable build from /download and point it at your existing model library in under two minutes.

FAQs
Can ComfyUI and Rented Cloud GPUs (RunPod / Civitai / Replicate) share the same models folder on Windows?
Yes. Edit `extra_model_paths.yaml` in your ComfyUI root folder to point `base_path` at your existing models directory so both apps load the exact same files.
Does ComfyUI use less VRAM than Rented Cloud GPUs (RunPod / Civitai / Replicate)?
ComfyUI only keeps the active node's sub-model (CLIP, UNet, or VAE) in VRAM at each step and supports native FP8 and GGUF quantization, making it significantly lighter on 8 GB and 12 GB GPUs.
