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

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
