Question

MiniMax-H3

Accepted Answer

MiniMax-H3 (also known as Hailuo 3) is a general-purpose, omni-modal generative AI model developed by MiniMax. Released in July 2026, it is designed to unify the understanding and generation of text, images, video, and audio within a single context.

### Key Features and Capabilities
*   **Unified Multimodal Generation:** Unlike models that use separate architectures for different tasks, H3 processes text, images, video, and audio simultaneously to generate coherent audiovisual content.
*   **High-Quality Video Output:** It supports video generation at up to **2K resolution** with durations ranging from **5 to 15 seconds**, complete with native stereo audio.
*   **Versatile Input:** The model can ingest complex multimodal prompts, including up to nine images (for subject and style), three video clips (for motion), and three audio tracks.
*   **Task Flexibility:** H3 supports a wide range of capabilities, including:
    *   **Text-to-Video:** Generating video from text prompts alone.
    *   **Image-to-Video:** Animating a single image or transitioning between a first and last frame.
    *   **Video Editing:** Performing precise edits on existing footage using natural language instructions.
    *   **V2V Motion Transfer:** Applying motion from one video to another.
*   **Open Weights:** MiniMax-H3 was released with open weights, allowing developers to explore, customize, and build upon the foundation model.

### H3 Max
A speed-optimized variant, **H3 Max**, was introduced in September 2026. Hosted and accelerated by platforms like Fal, it is capable of generating 5-second, 768-resolution clips with audio in under 3 seconds. It also features an "H3 Max Director" variant with extended contextual memory (up to two minutes), enabling applications like long-form, consistent narrative streams.
