MiniMax-H3 Ultra Fast

MiniMax-H3 Ultra Fast generates video and synchronized sound locally on one Blackwell ZeroGPU worker. The default Balanced preset is the best place to start. Choose Turbo 8-step for a larger speedup with moderate quality trade-offs, or Turbo 4-step when speed matters most. Add a start frame, an end frame, both, or neither.

The generated video includes synchronized sound. There is no prompt-to-video result cache: every click creates a new generation from your prompt, images, and seed.
