What is MiniMax H3 Max Turbo?

MiniMax H3 Max Turbo is the distilled, speed-focused version of MiniMax H3 Max. It renders 480p or 768p video at 24 fps with native audio, runs 5 to 15 seconds per generation, and takes two kinds of input: text alone, or a start frame with an optional end frame. It takes no reference images, videos or audio. A seed and a prompt expansion level (disabled, balanced, quality) are optional on every request.

Key features of MiniMax H3 Max Turbo

Distilled from H3 Max

A smaller model built for speed from the same base as H3 Max, with the same resolutions, durations, aspect ratios, seed and prompt expansion controls. It drops the reference inputs.

Text-to-video in six aspect ratios

Pick 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9 and 480p or 768p for a prompt-only render. There is no auto ratio because there are no references to match.

Start and end frame control

A start frame on its own, or a start and an end frame together. With a frame image set, output follows the input frame instead of aspect_ratio.

Seed and prompt expansion

A seed repeats a result with the same inputs. prompt_expansion sets how much the model rewrites the prompt: disabled sends it as written, balanced is the default, quality rewrites more.

Native audio in the same pass

Output arrives with an audio track generated alongside the picture, no separate audio step.

What MiniMax H3 Max Turbo is best for

Prompt-only drafts
Test a text prompt at 480p with sound before an H3 Max or H3 render.
Animating stills
Pass a start frame and describe the motion, or pin both ends with a start and an end frame.
High-volume social video
9:16 at 768p with native audio from prompts alone, at a per-second rate built for batches.
Repeatable renders
Fix the seed and set prompt_expansion to disabled to get the same result from the same request.

MiniMax H3 Max Turbo use cases

Draft ten versions of a text prompt at 480p to settle the framing, then render the keeper on H3 Max with reference images or on H3 at 2K. Animate a product still into a 5-second 9:16 video with sound. Build a short spot with a fixed open and close by passing a start and an end frame. Batch a week of prompt-only social videos at 768p.

MiniMax H3 Max Turbo limitations

H3 Max Turbo takes no reference images, videos or audio; for those use MiniMax H3 Max or MiniMax H3. It caps at 768p and the shortest generation is 5 seconds. An end frame needs a start frame, and with a frame image set, aspect_ratio is ignored. Duration is capped at 15 seconds per generation.
