Do not send the upstream slug

The upstream fal slug is minimax/h3-max. When calling OneInfer, use Minimax/minimax-h3-max instead so catalog lookup, pricing and analytics resolve to the canonical model.

H3 Max generates clips from 5 to 15 seconds at 24 fps.

Does MiniMax H3 Max generate audio?

Yes. It predicts synchronized audio alongside the video in the same generation.
