MiniMax H3

MiniMax H3 is an AI video generation workspace built around the MiniMax H3 model, released as Hailuo 3.0 on July 31, 2026. MiniMax H3 is a 33-billion-parameter dense omni-modal transformer that reads text, images, video and audio as a single context and returns video with the sound already generated inside it, rather than bolting a separate audio pipeline onto the picture.

Key Features
- Native audio: voice, effects and music are produced in the same pass as the picture at 32 kHz stereo, removing an entire production stage.
- 2K output: the base model renders at 768 pixels on the short edge and regenerates in-context to reach 2K, so detail holds instead of being interpolated by an upscaler.
- Clip control: durations run from 4 to 15 seconds at a fixed 24 FPS, across six documented aspect ratios including 16:9, 9:16 and 21:9.
- Multimodal references: reference briefs accept images, video clips and audio within a twelve-file ceiling, so identity and behavior can be carried by evidence text cannot express.
- Reproducible prompts: 24 prompt recipes pair each finished video example with the complete prompt behind it, ready to copy or send straight to the workspace.
- Documented comparisons: MiniMax H3 is measured against Veo 3.1, Sora 2 and Kling 3.0 on resolution, clip length, native audio and published per-second cost.

Use Cases
Marketing teams generate 2K social variants with sound in one pass instead of two. Short-drama and vertical creators get dialogue and ambience without a separate audio run. Studios use the comparison tables to decide between MiniMax H3, Veo 3.1 and Sora 2 before committing budget. Developers check the 42.5 GB minimum working set and VRAM notes before attempting a local deployment, and legal teams verify the community license terms, including the four excluded territories.

Pricing is freemium, with plans from $9.9 per month, and hosted generation at $0.13 per 2K second.
