MiniMax H3 generates 15-second 2K video

MiniMax launched H3, an omni-modal model that generates up to 15 seconds of 2K video with native stereo audio from combinations of text, images, video, and audio. The company’s H3 announcement says 2K output costs less than one-third as much per second as unspecified mainstream models and promises open weights in the coming days, while the live API documentation confirms 4-to-15-second generation and 2K output. For creative teams comparing it with FLUX 3’s gated 20-second audiovisual model, H3 is worth testing now, but its self-reported price advantage and future-tense weight release still need independent verification.
