MiniMax H3 で開発
テキスト動画生成、画像動画生成、ネイティブ音声、非同期プロダクション API に対応します。
テキストから動画
テキストプロンプトを MiniMax H3 API に送信して動画を生成します。
画像から動画
先頭フレーム画像とプロンプトを指定して、動きやシーンを制御します。
ネイティブステレオ音声
完成した MP4 には、映像と同期した生成ステレオ音声が含まれます。
Flexible video output
Choose 512p or 768p resolution and generate clips from 5 to 15 seconds.
非同期 API ワークフロー
タスクを作成し、返されたタスク ID をポーリングして、完成した動画 URL を取得します。
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 よくある質問
MiniMax H3 API とは何ですか？
テキストプロンプトまたは先頭フレーム画像から、ネイティブステレオ音声付き MP4 動画を生成する API です。
MiniMax H3 は画像から動画を生成できますか？
はい。画像動画モードを選び、公開可能な JPG または PNG の先頭フレーム画像とプロンプトを指定します。
対応する解像度と長さは？
PiAPI の MiniMax H3 は 512p と 768p、5～15 秒の生成に対応しています。
PiAPI から MiniMax H3 を呼び出す方法は？
txt2video または img2video タスクを作成し、完了までタスク ID をポーリングして、結果の動画 URL を取得します。
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.
