Official model overview
What Is MiniMax H3?
MiniMax H3 is the company's officially released general-purpose multimodal generation model, announced on July 31, 2026. It understands unified context across text, images, video, and audio, and every clip is generated with native sound rather than a separate audio pass.
On SoraVideo it is exposed as three routes that match how you start: a text prompt, keyframes, or reference media. Frame inputs and reference inputs are mutually exclusive upstream, so the generator switches routes with the mode you pick instead of silently dropping fields.
Output is 2K MP4 from 4 to 15 seconds. Billing runs per second of output, and failed tasks are refunded in full, so an unusable render costs you nothing.
Naming guide
MiniMax H3 vs MiniMax M3: Do Not Mix Them Up
MiniMax M3 is the company's coding and agentic language model with a long context window and native multimodal understanding. It reads text, images, and video, but it does not generate video — that is the job of the Hailuo line and now H3.
H3 also answers to Hailuo 03 and Hailuo 3 in search results; all three names point at the same video family. The reliable rule: M3 for coding and agents, H3 for multimodal generation.
If you want the previous generation, Hailuo 2.3 remains available on its own page with per-video pricing at 768p and 1080p.

How to Generate AI Video with MiniMax H3
Three steps from prompt to a downloadable 2K clip.
- 1
Pick a Route
Choose text-to-video for a prompt alone, image-to-video to animate a first or last frame, or reference-to-video to anchor characters and style with reference images.
- 2
Write a Directed Prompt
Describe subject, action, setting, lighting, and camera movement. In reference mode, name your assets as Image 1, Image 2 and so on so the model knows which is which.
- 3
Set Duration and Generate
Pick a length from 4 to 15 seconds and an aspect ratio, review the credit cost shown on the button, then generate and download the finished MP4.
