Wan2.2-S2V is an open-weight video model from FastVideo, 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
Wan2.2-S2V-14B (Diffusers layout) This is Wan-AI/Wan2.2-S2V-14B — a model that animates a picture of a person in sync with a voice recording — repacked into the folder layout that FastVideo loads. No weights were changed. The video model tensors are byte-identical copies of the official release. The text encoder, VAE, tokenizer and scheduler come from Wan-AI's own Diffusers release of Wan2.1 (the same weights S2V uses), and the wav2vec2 speech encoder is the one bundled inside the official S2V repo. Made with scripts/checkpointconversion/wans2vtodiffusers.py from FastVideo PR #1683. Verification status - Checked: all 1260 video-model tensors load into FastVideo's model with the correct names and shapes (the conversion script verifies this automatically and refuses to produce output otherwise). - Not yet checked: end-to-end video generation on a GPU. If you run it and find problems, please comment on the PR above. Usage (with FastVideo, once PR #1683 is merged)

Using it via the API
Once AxForge deploys fastvideo-wan2-2-s2v for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (fastvideo-wan2-2-s2v 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":"fastvideo-wan2-2-s2v","prompt":"a drone shot over a forest"}'
