# Model Registry

> Curated download URLs and target directories for every model the comfyui-mcp skills reference — checkpoints, VAEs, text encoders, LoRAs — organized by family (Flux, WAN, LTX, Qwen, Z-Image, SD15/SDXL). Use when downloading models with download_model / download_civitai_model, when a workflow fails with a missing-model error, or when setting up a new machine.

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# Model Registry

One table per family: filename → source URL → target subdir under
`/models/`. Use with `download_model(url, target_subfolder, filename)`.
This registry grows with every release — if a model you need is missing, use
`search_models` (HuggingFace) or `download_civitai_model` and consider
contributing the row.

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

## Shared VAEs & text encoders (download these once)

## WAN 2.x video (see `wan-t2v-video` / `wan-flf-video` skills)

Comfy-Org repackages everything: `huggingface.co/Comfy-Org/Wan_2.2_ComfyUI_Repackaged` under `split_files/`.

| File | Path in repo | Target |
|---|---|---|
| `wan2.2_i2v_high_noise_14B_fp8_scaled.safetensors` | `split_files/diffusion_models/` | `diffusion_models/` |

| Camera-control LoRAs (`dolly-left`, distilled-384) | `huggingface.co/Lightricks/LTX-2` LoRA dir | `loras/` |

## Qwen-Image (see `qwen-txt2img` / `qwen-image-edit` skills)

| File | Source | Target |
|---|---|---|
| `qwen_image_fp8_e4m3fn.safetensors` | `huggingface.co/Comfy-Org/Qwen-Image_ComfyUI/resolve/main/split_files/diffusion_models/qwen_image_fp8_e4m3fn.safetensors` | `diffusion_models/` |

| File | Source | Target |
|---|---|---|
| `z_image_turbo_bf16.safetensors` | `huggingface.co/Comfy-Org/z_image_turbo` — check repo for split_files path | `diffusion_models/` |

| `qwen_3_4b.safetensors` (Z-Image text encoder) | Comfy-Org repackage, `split_files/text_encoders/` | `text_encoders/` |

## SDXL / SD1.5 community checkpoints (CivitAI)

Use `download_civitai_model(model_id)` — it resolves the latest version and
handles auth:

| Model | CivitAI |
|---|---|
| RedCraft RedZ ImageDX | `civitai.com/models/958009` |
| (2027494 entry in model-settings.json) | `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** — file landed in the wrong `models/`
  subdir; check the Target column and `model-compatibility`.
- Downloads resume automatically on retry (HTTP Range) — re-run the same
  `download_model` call after a network drop.
