SCAIL-2 is an open-weight video model from realrebelai, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
SCAIL-2 GGUFs (by Rebel AI) GGUF quantizations of SCAIL-2, the end-to-end character-animation / video motion-transfer model (Wan 2.1 14B backbone) from zai-org. These run the SCAIL-2 DiT in ComfyUI at a fraction of the VRAM the full fp16/fp8 weights require. Quantized by RealRebelAI · GitHub · YouTube ⚡ Load with the GGUF Unet Loader (city96's ComfyUI-GGUF — Unet Loader (GGUF)). Place the .gguf in ComfyUI/models/unet/. Quant tiers The loader memory-maps the model, so a larger file costs disk and streaming time, not resident RAM. Required files (NOT included in this repo) Download each of these separately and place them in the listed ComfyUI folder. 📝 Text Encoder ComfyUI/models/textencoders/ 🎛️ LoRA (LightX2V step/cfg distill) ComfyUI/models/loras/ 🎯 SAM 3.1 Multiplex ComfyUI/models/sam/ 👁️ CLIP Vision ComfyUI/models/clipvision/ 🎨 VAE ComfyUI/models/vae/ ➕ Optional: SCAIL-2 DPO LoRA (untested) ComfyUI/models/loras/ Folder structure Generated Examples Here are some outputs from the model: Notes - WEIGHT NOT MERGED warning on patchembedding is harmless. ComfyUI builds a 36-channel patch embedding and concatenates the mask channels at runtime; the model fills them internally. The stored 20-channel weight is expected. Generation proceeds normally. - The colored mask is a required input even in single-character Animation Mode — don't remove it from the workflow. - Set width and height explicitly (both divisible by 16; 832×480 is a good 480p start). - The SCAIL2ColoredMask node may require a recent / nightly ComfyUI build.

How it works
Variants
Open weights ship in several sizes and precisions. One page, all the variants — pick the one that fits your GPU. VRAM figures are estimates from model size.

Using it via the API
Once AxForge deploys scail-2 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (scail-2 below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"scail-2","prompt":"a drone shot over a forest"}'
