SCAIL-2 is an open-weight video model from zai-org, 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: Unifying Controlled Character Animation with End-to-end In-Context Conditioning SCAIL-2 is an open-source model for end-to-end controlled character animation. It animates a reference character with a driving video, and also supports character replacement and multi-character scenarios without relying on intermediate pose representations. 🔎 Overview Prior approaches to character animation depend heavily on intermediate representations such as skeleton maps or inpainting masks. These intermediates are ambiguous under complex motion, restrict driving sources to human movements, and limit the reach of replacement and multi-character animation. SCAIL-2 removes this dependence and achieve End-to-end Driving. Using several off-the-shelf models (SCAIL-Preview, Wan-Animate, MoCha), 60K motion pairs were synthesized and trained through a Unified Motion Transfer Interface with dedicated masking channels and RoPE design. The reverse driving training recipe with the unification lets the model learn capabilities beyond its teacher models, yielding emergent abilities such as: - Cross-identity character replacement - Animal-driving scenarios - Zero-shot support for advanced control intermediates like SAM3D-Body mesh rendering 📦 Model File layout after download: 🚀 Usage Inference code, environment setup, and detailed instructions are provided in the project repository.

Using it via the API
Once AxForge deploys zai-org-scail-2 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (zai-org-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":"zai-org-scail-2","prompt":"a drone shot over a forest"}'
Licence
Open weights under mit — commercial use is permitted. Deploy it on AxForge EU hardware on request. Read the licence ↗
