MiniMax has officially released H3, a general-purpose omni-modal generation model that understands and generates text, images, video, and sound, with native dual-channel audio and video output up to 15 seconds at 2K resolution. H3 excels in instruction following, text and brand presentation, and video-to-video motion transfer, making it suitable for advertising, e-commerce, gaming, and more.

Technical highlights:

Contextual Omni Representation: Enhances multi-modal context understanding, unifying task descriptions via language.
H3-VAE: High compression yields 4x sequence length efficiency, reducing training and inference costs.
H3-OmniTransformer: Heterogeneous architecture for understanding and generation, boosting end-to-end training throughput by 30%.
In-context Regeneration: Uses the base model to regenerate low-res outputs, surpassing traditional super-resolution.

Pricing: Under 1/3 the per-second cost of mainstream models at 2K, and under 1/2 at 768P.

Open-source plan: Weights to be released in the coming days, with compatibility for domestic chips.

Design philosophy: Breaking task boundaries, moving from specialized to general, unifying image, video, and audio generation tasks.
