alibaba/happy-horse/text-to-video
Input requirements belong to this model ID. Check a different mode’s schema separately when switching modes.

From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
