MiniMax H3 fast video generation: web, API and pricing

Text-to-video: start with an idea

Describe the subject, action, setting, camera movement and sound. MiniMax H3 turns that prompt into an AI-generated video. A clear sequence of actions gives the scene a direction; add visual details that support it.

Example: A vintage tram follows the coast at sunrise. The camera tracks smoothly alongside it as a sea breeze moves the trees. Use only wheel sounds and waves, with no background music.

Image-to-video: animate a still image

Upload an image as the starting frame and describe what happens next. Image-to-video can bring a product image, character or environment into motion. Explain the movement of the subject and camera, rather than simply describing what is already visible.

First-and-last-frame generation lets you provide both endpoints of a shot. Reference-based generation can combine images, reference video and audio to guide the result. Check the workspace for the current file and reference limits.

Three quality options, nine aspect ratios

Choose 480P, 768P or 1080P with nine aspect ratios and 4–15 seconds of output. 480P and 768P are native; 1080P uses AI upscaling.

Task pages display actual progress for the current processing stage. Percentages can reset when moving between reference processing, generation and output saving.

Processing time depends on content, references, queues and service load. No fixed completion time is guaranteed. Output duration is the video playback length; billing uses output video seconds, not processing time.

How much does AI video generation cost?

Every registered account is a free permanent member. Current CNY rates per output video second: 480P 0.05, 768P 0.08, 1080P 0.10. Confirm a live quote before submission.

Web and API use fixed route3 with the public model identifier superh3, one concurrent generation per account. No monthly plans, upgrades or signup vouchers. Paid balance does not expire.

AI video generation API for your application

Register your own account, recharge or purchase a plan, then create your own API key in your account's API page. Configure it securely on your computer or application server and use https://superh3.com/api/v1. Do not publish it in a repository, browser frontend or shared document.

Use the SuperH3 API to upload media, obtain a quote, submit a video generation job, check its status and download the result. It supports text, image, first-and-last-frame and reference workflows using the same account balance and concurrency limits as the workspace.

Reuse the same idempotency key when retrying a request so that a network interruption does not create a duplicate job. Use a SuperH3 API key with the SuperH3 endpoint and follow the service's developer documentation.

Make your first video on SuperH3

Create an account, enter the workspace and choose a generation mode. Write a prompt or upload media you have permission to use, then choose the duration, aspect ratio and resolution. Review the quote before submitting and download the finished video within the retention period shown on the task.

This page is an English introduction. The workspace, pricing details and support pages currently use Chinese, and payments are denominated in CNY. SuperH3 Studio provides the site's accounts, billing and support.

Public documentation, AI-readable information and GitHub examples

The website, pricing page, developer documentation and llms.txt describe the service and its usage rules. The public GitHub repository contains SuperH3 usage instructions, API client examples and service information for developers and AI assistants. A public repository does not make video generation free or provide the hosted backend or model weights.

SuperH3 provides the accounts, hosting, billing and support for this service; MiniMax H3 is the model name. Use the SuperH3 documentation for this service's endpoints and plans.
