Model Registry

One table per family: filename → source URL → target subdir under <COMFYUI>/models/. Use with download_model({ action: "download", url, target_subfolder, filename }). This registry grows with every release. If a model you need is missing, use action:"search" (HuggingFace) or action:"download_civitai" and consider contributing the row.

Quant column (kitchen). Filenames in this registry are mostly bf16 / fp8. NVFP4 and MXFP8 siblings, when a vendor publishes them, are the same stem with nvfp4 / mxfp8 in the name and belong in diffusion_models/ too. kitchen action:"assess" only offers an NVFP4 swap when that sibling is already listed locally — it does not guess a URL from the filename. Blackwell (SM ≥ 10.0) is the GPU that can run NVFP4 / MXFP8 compute.

Conventions

• HF "resolve" URLs download directly: https://huggingface.co/<repo>/resolve/main/<path>
• 🔒 = gated repo, needs HUGGINGFACE_TOKEN (accept the license on the HF page first)
• CivitAI model-page URLs need download_model action:"download_civitai" (resolves version → file); raw civitai.com/api/download/... URLs work with action:"download" + CIVITAI_API_TOKEN
• Always verify the exact filename a workflow's loader expects. The model-compatibility skill covers which VAE/CLIP pairs with which architecture
