•required

Text description of the motion to be generated.

default 5

Length of the motion in seconds, ranging from 0.5 to 12.0.

Advanced output_format · guidance_scale · seed
output_format default fbx

Output format selection: 'fbx' produces animation files, while 'dict' produces raw JSON.

default 5

Scale for classifier-free guidance; larger values increase fidelity to the prompt.

Random seed that makes generation reproducible.

About Hunyuan Motion [1B]

Generates 3D human motion from a text `prompt`. `duration` runs from 0.5 to 12 seconds, defaulting to 5, and `guidance_scale` runs from 1 to 10. `output_format` selects an FBX animation file or raw motion data as a dict. This is the larger 1B version.
