Overview
What is MiniMax H3?
MiniMax H3 (Hailuo 03) is MiniMax's general video model, built to read text, images, video and audio together and follow detailed instructions about all of them. On Zurelay it makes 768p and 2K clips from 4 to 15 seconds long with native sound, from a prompt and up to 9 reference images, 3 reference videos and 3 reference audio clips in any mix. The Zurelay MiniMax H3 API starts at $0.065 per second, below MiniMax's own price, with the references included.
MiniMax released H3 in July 2026 as a general-purpose system for video: one model that takes text, images, video and audio as context and generates video with native stereo sound. It is also known as Hailuo 03. On Zurelay it uses the model ID minimax-h3, and also accepts MiniMax's own name, MiniMax-H3.
On Zurelay, MiniMax H3 makes video from a prompt and up to 9 reference images (people, products, places or a style), up to 3 reference videos whose motion and camera work it can follow, and up to 3 reference audio clips, as MP3 or WAV, for a voice or a soundtrack. Write the words in the prompt and a voice clip sets how they're spoken: in our tests the character said the lines word for word, in sync. Reference videos run 2 to 15 seconds each and 15 seconds in all, and so do audio clips. Zurelay doesn't offer H3 with a fixed first or last frame: give the image as a reference and say how the video opens.
Clips come in 768p or 2K, in whole seconds from 4 to 15, in 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9. A 16:9 clip is 1376 × 768 at 768p and 1920 × 1088 at 2K, MiniMax's own sizes. Sound is always generated. The API is asynchronous: POST https://api.zurelay.com/v1/videos returns a job right away; poll GET /v1/videos/{id} until it's completed and download the MP4. A 5 second 768p clip usually takes about 2.5 minutes.
Zurelay prices MiniMax H3 by the second: $0.065 per second at 768p and $0.10 at 2K, against MiniMax's $0.08 and $0.13. MiniMax also bills reference video by the second and reference images past the fifth; on Zurelay, reference images, videos and audio cost nothing extra. The price is held from your balance when the job is accepted and charged only when the video is delivered; videos that fail cost nothing.
Strengths
Where MiniMax H3 shines. And what teams build with it.
Speaks your lines in a given voice
Write the words in the prompt and add a voice clip: the character says them in that voice, with the lips in sync.
Native 2K
2K comes out of the model in one pass at 1920 × 1088 for 16:9, not upscaled from 768p.
Below MiniMax's price, references included
$0.065 per second at 768p and $0.10 at 2K, under MiniMax's own $0.08 and $0.13, and reference media never adds to the bill.
Use cases
Spokesperson and UGC ads
A presenter image, a voice clip and the script in the prompt make a talking ad in 9:16, ready for social.
Product videos
Give product photos as references and describe the scene, the camera and the sound.
Motion from a reference clip
Hand it a video whose movement or camera work you like and describe a new subject to carry it.
Music-driven clips
Add a music clip and ask for movement to the rhythm, for dances, loops and teasers.

Wan 3.0 APIHow much does the MiniMax H3 API cost?
Zurelay charges by the second of video: $0.065 per second at 768p and $0.10 at 2K, so a 5 second 768p clip is $0.325. MiniMax's own price is $0.08 and $0.13 per second. Sound, reference images, reference videos, reference audio and the aspect ratio don't change the price.
Can MiniMax H3 use my audio files?
Yes. Pass up to 3 MP3 or WAV clips in reference_audio, as https links or base64 data URLs, 2 to 15 seconds each and 15 seconds in all. A voice clip sets how a character sounds: write the exact words in the prompt, in quotes, and the character speaks them in that voice with matching lip movement. A music clip can be the soundtrack: say in the prompt to use the reference audio itself as the whole soundtrack, instrumental only, with no singing or text on screen, or the model may write its own song. Audio can come alone or with reference images and videos.
Does MiniMax H3 take a first frame or a last frame?
Not on Zurelay. MiniMax H3 here works from reference images instead: pass the image in reference_images and describe how the video opens. A request with first_frame or last_frame is refused at once with a message saying so, before anything is charged.
How do I call the MiniMax H3 API?
Send POST https://api.zurelay.com/v1/videos with your Zurelay key as a Bearer token and a JSON body: model set to minimax-h3, a prompt, and optionally reference_images, reference_videos, reference_audio, seconds (default 5), resolution (768p by default, or 2k) and aspect_ratio (default 16:9). You get a job back right away. Poll GET /v1/videos/{id} until its status is completed, then download the MP4 from /v1/videos/{id}/content.
How long does a MiniMax H3 video take?
A 5 second 768p clip usually takes about 2.5 minutes. 2K, longer clips and reference videos take longer. While you poll, the job's progress field gives an estimate from 0 to 100.
What resolutions, lengths and aspect ratios does MiniMax H3 support?
768p and 2K, in whole seconds from 4 to 15, in 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9. A 16:9 clip is 1376 × 768 at 768p and 1920 × 1088 at 2K; MiniMax aligns frames to 32 pixels.
When am I charged for a video?
When Zurelay accepts the job, its price is held from your balance, and it's charged only when the video is delivered. If a video fails, including when the content filter refuses the prompt or a reference, you pay nothing.
Is this MiniMax's H3?
Yes. Your requests run on MiniMax H3, and Zurelay checks that videos come back at H3's own frame sizes. Video generation varies from run to run, so the same prompt makes a different clip each time. Zurelay is an independent service and is not affiliated with MiniMax.
