## Product details
- Category: video
- Vendor: minimax

### Facts
- Text-to-video: Create a video from a text prompt with the MiniMax H3 API.
- Image-to-video: Provide a first-frame image and prompt to guide the generated video.
- Native stereo audio: Completed MP4 outputs include a generated audio track muxed with the video.
- 480p, 768p, and 1080p: Choose 480p for the lower-cost option, 768p for a balance, or 1080p for the highest-resolution output.
- 5–15 second clips: Set the requested duration between 5 and 15 seconds.
- Async task workflow: Submit a task, poll its status, and retrieve the completed video URL.
- Managed MiniMax H3 API: Use MiniMax H3 through PiAPI without downloading model weights or operating GPU provisioning, inference, scaling, monitoring, and upgrades.
- Content policy: The PiAPI endpoint follows applicable model moderation and PiAPI's NSFW policy; local open-weight behavior does not guarantee hosted API behavior.
- Community variants and LoRAs: PiAPI will follow the MiniMax H3 open-source community and evaluate useful model variants and LoRAs for future managed API access.

## FAQ
### What is MiniMax H3 API?

MiniMax H3 API is a video generation API that creates MP4 video with native stereo audio from text prompts or a first-frame image.

### Does MiniMax H3 support image-to-video?

Yes. For image-to-video, provide a public JPG or PNG image as the first frame together with a prompt.

### What resolution and duration does MiniMax H3 support?

MiniMax H3 supports 480p, 768p, and 1080p output with requested durations from 5 to 15 seconds.

### How do I call MiniMax H3 through PiAPI?

Create a PiAPI API key, submit a txt2video or img2video task, poll the task status, and read the completed video URL from the response output.

### Is MiniMax H3 a Seedance alternative?

MiniMax H3 is a practical Seedance alternative for developers who need text-to-video, first-frame image-to-video, and native stereo audio through a managed AI video API. Seedance is a better fit when a workflow specifically needs PiAPI's broader multi-image, video, or audio reference modes.

### How does MiniMax H3 compare with Kling AI?

MiniMax H3 is a cost-conscious Kling AI alternative for text-to-video and first-frame image-to-video with native stereo audio. Kling offers a broader model family and additional reference and generation controls. PiAPI lets you test both API workflows before choosing a model for production.

### Why use the MiniMax H3 API on PiAPI instead of self-hosting?

PiAPI provides a managed MiniMax H3 API without the GPU capacity planning, model downloads, ComfyUI setup, storage, scaling, monitoring, upgrades, and security work required by local deployment. Start in the PiAPI Playground, then use the same asynchronous API workflow in production.

### Is MiniMax H3 an uncensored AI video generator?

Some community users describe local MiniMax H3 open-weight workflows as uncensored, but results and moderation vary by checkpoint, runtime, and hosting provider. PiAPI does not promise an unfiltered endpoint: requests must follow applicable model moderation and PiAPI's NSFW content policy.

### Will PiAPI support MiniMax H3 community variants and LoRAs?

PiAPI will continue following the MiniMax H3 open-source community and evaluating useful community model variants and LoRAs. Any future managed API availability will depend on compatibility, output quality, licensing, safety, stability, and production demand.
