使用 MiniMax H3 构建应用
支持文生视频、图生视频、原生音频和适用于生产环境的异步 API。
文生视频
通过文字提示词调用 MiniMax H3 API，生成完整视频。
图生视频
上传首帧图片并添加提示词，引导视频中的运动和场景。
原生立体声音频
生成完成的 MP4 视频包含与画面同步的原生立体声音轨。
Flexible video output
Choose 512p or 768p resolution and generate clips from 5 to 15 seconds.
异步 API 工作流
创建任务后轮询返回的任务 ID，并从完成结果中读取视频地址。
Managed API access
Use the open-weight MiniMax H3 model without downloads, GPU provisioning, ComfyUI setup, or inference maintenance.
Seedance and Kling alternative
A cost-conscious option for text-to-video, first-frame image-to-video, and native audio workflows.
Community roadmap
We will evaluate useful MiniMax H3 community variants and LoRAs for future managed API access.

MiniMax H3 API 常见问题
什么是 MiniMax H3 API？
MiniMax H3 API 可以根据文字提示词或首帧图片，生成带有原生立体声音频的 MP4 视频。
MiniMax H3 支持图生视频吗？
支持。选择图生视频模式，上传可公开访问的 JPG 或 PNG 首帧图片，并提供提示词。
支持哪些分辨率和时长？
PiAPI 的 MiniMax H3 接入支持 512p 和 768p，生成时长可以设置为 5 至 15 秒。
如何通过 PiAPI 调用 MiniMax H3？
创建 txt2video 或 img2video 任务，轮询任务 ID 直到完成，然后从返回结果中读取生成的视频地址。
Why use the MiniMax H3 API on PiAPI instead of self-hosting?
PiAPI gives developers 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. You can start in the PiAPI Playground, then use the same asynchronous API workflow in production.
Is MiniMax H3 a good 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.
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.
