Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read

Image 01 Subject Reference
Image 01 Subject Reference is built for high-fidelity image generation, with this exact route focused on subject-consistent creation. Image 01 Subject Reference by MiniMax - AI-powered image editing, style transfer, and transformation. Edit photos with natural language instructions, remove backgrounds, change styles, and enhance images effortlessly. It is designed for production workflows that need a clearly scoped media operation instead of a generic assistant response, preserving the supplied direction while returning an artifact ready for review, iteration, or downstream assembly.
The request surface keeps creative direction and delivery choices explicit through prompt, image_url, sync_mode, num_images, aspect_ratio, prompt_optimizer. Teams can lock source material, describe the intended result, choose supported output controls, and rerun the same request structure across variations. This makes experiments easier to compare and larger pipelines easier to operate without hiding important decisions inside an opaque preset.
Highlights
- Subject-Consistent Creation. The
minimax/image-01/subject-referenceroute is dedicated to subject-consistent creation, keeping inputs and outputs matched to this operation. - Detailed Composition And Lighting. Within
minimax/image-01/subject-reference, documented prompt and media controls direct detailed composition and lighting while keeping the brief close to the result. - Creative Production Assets. The
minimax/image-01/subject-referenceresult provides creative production assets in a machine-consumable form for review and downstream production. - Route-specific control. For
minimax/image-01/subject-reference, documented controls includeprompt,image_url,sync_mode,num_images,aspect_ratio,prompt_optimizer, defining the supported variation space for this exact route.

When to Use
| Scenario | Why it fits |
|---|---|
| Choose this route | When the deliverable is specifically subject-consistent creation, not a neighboring generation or editing task. |
| Production iteration | When creative teams need repeatable detailed composition and lighting with an explicit request payload. |
| Automated pipelines | When creative production assets must flow into review, storage, compositing, or publishing. |
| Controlled variations | When a stable brief should be rerun while changing only documented inputs. |
| Prototype to scale | When the same minimax/image-01/subject-reference contract should serve a single experiment and a larger batch later. |
Prompt Guide
Lead with the subject or source, then state the transformation, important spatial or temporal details, style, and finish. Supply only documented fields, keep media URLs reachable, and vary one control at a time when comparing outputs.
{
"prompt": "A directed creative request with subject, setting, style, motion, and finish.",
"image": "https://example.com/reference.jpg"
