Explore visual directions with MiniMax H3 Image Highspeed, MiniMax’s faster hosted option for text-to-image and reference editing. Keep the same output sizes and reference limits as the standard model.
Describe the image or the change to make.
Upload images or paste public image URLs. Up to 16 references, in the order you want them used.
Default 1; up to 10 images.
Optional auto or WIDTHxHEIGHT. When using pixel dimensions, leave area and aspect ratio unset.
Leave unset for automatic framing, or enter X:Y between 1:3 and 3:1.
Leave unset for the 4K default. Area is a pixel-area target, not a fixed edge length.
For new generations only. Requires an explicit aspect ratio or pixel size. Reference editing always enhances prompts.
JPEG by default; PNG and JPG are also accepted.
0–100, default 95. Zero is sent as zero.
Off by default.
URL delivery through the asynchronous task API.
Keep off: this integration uses asynchronous tasks.

The starting values are an example, not a fixed price per image. Enter totals for all images in a batch; count shared inputs once. Image dimensions alone do not determine the final token usage.
MiniMax H3 Image Highspeed is the faster hosted variant of MiniMax’s H3 image model, with the same generation and editing parameters as the standard version. Work from a written scene or a set of reference images, with output up to 20 million pixels through custom dimensions. The useful distinction is speed positioning: Highspeed does not add more references, transparent output or masked editing.
Real-world workflows and production use cases you can build and ship with this model.
Use MiniMax H3 Image Highspeed when a creative session calls for successive variations of a scene. Keep the same subject and framing while changing the palette or light, so the comparison answers one question. MiniMax positions Highspeed for faster generation; review time and output quality still matter to the final choice.

Give MiniMax H3 Image Highspeed a product reference and describe the new setting separately. For a shoe campaign, keep the shoe’s shape and stitching while asking for a pale studio floor. Inspect those details after the edit; a reference guides the result but does not guarantee an exact copy.

Plan a set of related images with MiniMax H3 Image Highspeed by reusing a visual brief and assigning each reference a role. Try one composition before expanding the series. Repeated colors and subjects are useful directions, but each result needs a consistency check before it sits beside the others.
MiniMax positions MiniMax H3 Image Highspeed as its higher-speed option. Consider it when shorter waits between creative revisions matter; the documentation does not establish a fixed completion time for your workload.
MiniMax H3 Image Highspeed retains the standard version’s reference count and output sizing options. You can compare the two versions using the same brief without inventing a separate image format or reference workflow.
MiniMax H3 Image Highspeed is a distinct hosted variant, not an extra resolution tier. Compare representative images against your actual brief, including fidelity and total workflow time, before deciding which version suits the work.
Give MiniMax H3 Image Highspeed a subject, setting and composition, then name the detail that will decide whether the image works. For example: an amber bottle on pale stone, side lighting, and open space at the left for a headline.
For a MiniMax H3 Image Highspeed edit, put the main subject first and explain what later images contribute. Use only references that help the brief, within the 16-image limit; conflicting instructions make it harder to judge the result.
Choose an area level with an aspect ratio, or exact dimensions, in the MiniMax H3 Image Highspeed playground. Generate the image and inspect it against your brief before making another revision. The scene posters are concept illustrations; the playground shows an actual model output.
MiniMax H3 Image Highspeed generates images from a written scene. Include subject placement and light direction when those details determine whether a composition fits your project.
MiniMax H3 Image Highspeed accepts one to sixteen images for editing. Assign roles explicitly: subject, setting or appearance. More references are not automatically better direction.
MiniMax H3 Image Highspeed offers 1K, 2K and 4K area levels, or custom dimensions up to 20 million pixels. Choose a canvas that matches the intended layout.
MiniMax H3 Image Highspeed supports up to ten output images in a request. Review each returned image separately; a larger batch does not guarantee every candidate meets the brief.
MiniMax H3 Image Highspeed expands prompts by default. Text-to-image can disable enhancement with fixed framing; edits always use it. Review the revised prompt when diagnosing an unexpected result.
MiniMax H3 Image Highspeed does not support masked edits, transparent backgrounds or preview images in the documented service. Use another tool when your deliverable depends on those features.
MiniMax H3 Image Highspeed and MiniMax H3 Image share their documented image controls. Choose between their delivery options and speed positioning, then judge actual images against your brief.
