MiniMax H3 Is Live: Native 2K Video, One Pass, and a Lower Cost Per Second

MiniMax H3 is presented as a multimodal video-generation model on Atlas Cloud that produces native 2K, 24 fps video with synchronized stereo audio in a single generation pass, combining text, images, video references, and optional audio instructions rather than requiring separate visual and sound tools. It offers text-to-video, image-to-video, and reference-to-video modes under one API key, with the reference workflow supporting up to nine mixed image and video assets plus one audio track to preserve characters, products, or styles across scenes. As of July 2026, its listed pricing is $0.14 per second for 2560-by-1440 output and $0.10 per second for 768p, positioning its 2K rate below the cited $0.24-per-second cost of Seedance 2.0 at 720p. The examples emphasize applications including trailers, branded content, animated title sequences, music videos, motion posters, game interfaces, and product landing-page demonstrations, showing that prompts can specify visual style, camera movement, timing, text, transitions, and sound. Users can test the model through a browser Playground or access it through Atlas Cloud’s shared API workflow, where authentication, polling, and result retrieval remain consistent across supported models.
