MiniMax H3 is a general-purpose multimodal AI video model created by MiniMax, the team behind the Hailuo series. It understands unified context across text, images, video, and audio to generate up to 15-second videos with native stereo sound at a default 2K resolution — with open weights planned and pricing under a third of mainstream models.

Feed H3 a mix of images, video clips, and audio, then describe the relationship between them in plain language. H3 unifies the cross-modal context and generates a video that follows all of your references.
One prompt can reference the camera movement from one video, a character from an image, and vocals from an audio clip — all in a single generation.
Turn text prompts into high-resolution video. H3 follows detailed instructions including camera moves, subject behavior, and mood, producing 2K output out of the box.
Default 2K output at a per-second price below a third of mainstream models.
Animate still images, transfer motion from one clip to another, or edit existing footage. Reference and editing relationships are expressed in natural language, making video-to-video motion transfer a standout capability.
Video-to-video motion transfer makes in-place editing and character-driven animation remarkably simple.
Voice, sound effects, and music are jointly modeled in one unified architecture — no separate audio generation or mixing steps required.
True native stereo: dialogue, sound effects, and score are produced together with the visuals.
H3-VAE paired with in-context regeneration delivers a default 2K resolution with dramatically improved architecture efficiency — a strong fit for product demos, brand content, and UI/UX showcases.
Precise text and brand rendering makes H3 ideal for advertising, product, and e-commerce content.
Open weights are planned in the coming days (subject to applicable laws), with hardware compatibility considered since the earliest design stages. At 2K, H3's per-second price is under a third of mainstream models; at 768p, under half of mainstream 720p pricing.
Open weights plus aggressive pricing make H3 a highly cost-effective choice for commercial content creation.
