NVIDIA says it sped up MiniMax H3’s omni-modal video generation by 3.95× in 4.5 hours of inference-time optimization.
- MiniMax H3 is described as a 33B dense omni-modal generation model that takes text, images, video, and audio as a unified context and outputs short video clips with native stereo audio.
- The Sol Video Inference Engine got the speedup on 8× GB200, reaching 1344×768 at 24 fps and 124 frames.
- The optimization used kernel fusion, graph capture, cross-step caching, and sparse attention, with no distillation, fine-tuning, LoRA, or offline calibration.
- The blog frames this as a day-one deployment recipe for open-weight video models.
