Model Librarian

One-click downloads from CivitAI and HuggingFace into ComfyUI via Model Librarian, and pictures saved for Model Librarian Gallery.

The browser side of Model Librarian, a free, open-source model manager for ComfyUI. It needs Model Librarian (1.15 or newer) installed in the ComfyUI you download into. ComfyUI doesn't have to be open when you click: downloads wait in the extension and start when it is. One click per file A download panel on every CivitAI model page, every version and file: full, pruned, fp16, a bundled VAE. Also on HuggingFace file pages and CivArchive pages. Model Librarian does the download inside ComfyUI: the right folder for the model's type, a subfolder for its base model, a SHA256 check, resume, metadata and a preview. The best file for your PC Every file is rated against your GPU, its VRAM and the formats your ComfyUI runs at full speed (FP8, NVFP4, INT8/INT4, GGUF), with the reason the others are slower. A diffusion model's text encoder and VAE are marked when you have them, and fetched with the model if you like. Knows what you have Have and Update badges on CivitAI's model cards, and In your library in the panel. Nothing is downloaded twice. On a CivitAI image or post, the checkpoint and every LoRA it used, in one click, saved as a recipe. Saves pictures for Model Librarian Gallery Right-click any picture, or use the Save button on supported art sites, and it's saved full size to your Downloads folder with a note of its page, artist, title and tags, ready for the Gallery to file. Your keys stay home CivitAI and HuggingFace keys live in Model Librarian, never in the extension. No account, no analytics, and nothing is sent to the developer.
