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

SDXL / SD1.5 community checkpoints (CivitAI)

Use download_model({ action: "download_civitai", model_id }). It resolves the latest version and handles auth:

Model	CivitAI
RedCraft RedZ ImageDX	civitai.com/models/958009
Qwen Ultimate Realism v1.1	civitai.com/models/2027494
Copax Timeless	civitai.com/models/copaxTimeless (search by name)

Failure modes

• 404 on an HF resolve URL. The repo restructured. Open the repo page, find the file under "Files", and rebuild the resolve URL.
• 401/403. Gated repo. Set HUGGINGFACE_TOKEN after accepting the license, or CIVITAI_API_TOKEN for early-access CivitAI files.
• Wrong dropdown after download. The file landed in the wrong models/ subdir; check the Target column and model-compatibility.
• Downloads resume on retry (HTTP Range), so re-run the same download_model call after a network drop.

Sources

• Official: Hugging Face resolve-URL convention https://huggingface.co//resolve/main/; kitchen NVFP4/MXFP8 hardware gates in ComfyUI comfy/model_management.py and quant metadata in comfy/quant_ops.py.
• Empirical: the curated list and Civitai notes are ours, not a vendor catalog.
