MiniMax's pi-H3 video model achieves 2-4 step generation, bypassing VAE decoder

By PulseAugur Editorial · [1 sources] ·

MiniMax has announced pi-H3, a new video generation model that can produce videos in just 2 to 4 sampling steps. This model directly predicts pixels in its final step, eliminating the need for a VAE decoder and significantly increasing speed. On a single NVIDIA B200 GPU, pi-H3 can generate a 5-second HD video in under 4 seconds, making it more than twice as fast as previous models like Sol-H3. The model weights and code are set to be released on November 16th, with additional ComfyUI support planned. AI

IMPACT Accelerates video generation speeds and potentially lowers hardware requirements for AI video creation.
