What is the MiniMax H3 Max API?

The MiniMax H3 Max API exposes the Max tier of MiniMax's H3 line. It lets you select 480p, 768p or 1080p per request (the base MiniMax H3 offers 480p, 768p, 2k and 4k instead), and it takes up to 4 reference images. Its sibling MiniMax H3 Max Turbo is the speed-oriented variant that omits the reference-to-video mode.

4 ways to generate, one endpoint

Set mode, send the inputs it needs — that's it.

Text to video

mode: "t2v" · prompt

Just a prompt — the model builds the shot from scratch.

Image to video

mode: "i2v" · image_url

Send an image in image_url and it becomes the opening frame.

First and last frame

mode: "flf" · image_url + last_image_url

Set the first and last frame; the model animates everything in between.

Reference to video

mode: "r2v" · reference_images (≤ 4)

Add up to 4 reference images to lock in characters, products and style.

How much does MiniMax H3 Max cost per second?

MiniMax H3 Max vs MiniMax H3: which should I use?

MiniMax H3 Max is the pick for 480p, 768p or 1080p with up to 4 reference images. MiniMax H3 offers 480p, 768p, 2k and 4k instead and takes up to 5 references. If you don't need reference-to-video and want the speed-oriented option, use MiniMax H3 Max Turbo.

Max Turbo is the speed-oriented variant and does not offer reference-to-video. Max keeps that mode with up to 4 reference images.

Is the price locked after I request a quote?

Yes. A quote from POST /v1/generations/quote stays valid for 12 minutes, so the job you create within that window uses the quoted amount.
