MiniMax H3 Image Edit (Open Weights)

Run the open-weights edition of MiniMax H3 as a reference-guided image editor on WaveSpeedAI's own GPU infrastructure. Provide 1 to 9 reference images and an instruction; the model re-renders the subject into a new scene, outfit, pose or art style while preserving identity, at 1k or 2k resolution.

Why Choose This?

  • Strong identity preservation
    Faces, hairstyles, accessories and clothing details carry over from the references.

  • Scene, outfit and style changes
    Move a person to a new location, change what they wear, or restyle the image as a painting or animation.

  • Multi-image references
    Combine up to 9 references, addressed in the prompt as <Picture 1>, <Picture 2>, and so on.

  • Aspect ratio follows your input
    By default the output keeps the aspect ratio of the first reference image; override it with aspect_ratio.

Parameters

ParameterRequiredDescription
promptYesThe edit instruction. Refer to references as <Picture 1> .. <Picture N>.
imagesYes1 to 9 reference image URLs.
aspect_ratioNoOutput aspect ratio. Options: 1:1, 1:2, 2:1, 1:3, 3:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 9:21, or 21:9. Defaults to the first reference image's aspect ratio.
resolutionNoOutput resolution: 1k (default) or 2k.
output_formatNojpeg (default), png or webp.
seedNoRandom seed. -1 picks a random seed.

How to Use

  1. Upload references — One clear image of the subject is enough; add more for outfits, props or additional people.
  2. Describe the new image — State the new scene, outfit, pose and style explicitly, e.g. The same woman from <Picture 1>, now wearing a red leather jacket, standing in a neon-lit Tokyo alley at night. Photorealistic still.
  3. Choose resolution1k for iteration, 2k for final assets.
  4. Submit — Receive the edited image URL.

Pricing

Pricing is based on the selected resolution.

ResolutionCost per image
1k$0.03
2k$0.09

Best Use Cases

  • Virtual try-on and outfit swaps — Keep the person, change the clothes.
  • Scene relocation — Put a subject into a new environment with matching light.
  • Style transfer — Oil painting, anime or illustration versions of a photo.
  • Character sheets — Consistent renders of one character across settings.

Pro Tips

  • Describe the new scene fully instead of only naming the reference; short prompts that just say "the person from <Picture 1>" tend to reproduce the reference.
  • For style transfer, say so explicitly, e.g. This is a painting, not a photograph.
  • Keep the subject's key features in the prompt (hair, glasses, beard) when they matter.
  • Fix the seed to iterate on wording without changing the composition.

Minimax H3 Image Edit API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/minimax-h3/image-edit with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Minimax H3 Image Edit below.

Minimax H3 Image Edit API — Frequently asked questions

What is the Minimax H3 Image Edit API?

Minimax H3 Image Edit is a WaveSpeedAI model for image editing, exposed as a REST API on WaveSpeedAI. MiniMax H3 Open Weights Image Edit re-renders a subject from up to 9 reference images into a new scene, outfit or style from a text instruction, preserving identity at 1K or 2K resolution. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Minimax H3 Image Edit API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/minimax-h3-image-edit.

How much does Minimax H3 Image Edit cost per run?

Minimax H3 Image Edit starts at $0.030 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Minimax H3 Image Edit accept?

Key inputs: `prompt`, `images`, `aspect_ratio`, `resolution`, `seed`, `enable_base64_output`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/minimax-h3-image-edit.

How do I get started with the Minimax H3 Image Edit API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Minimax H3 Image Edit outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
