Technical Specifications of mj-fast-upscale-creative

What is mj-fast-upscale-creative?

mj-fast-upscale-creative is CometAPI’s platform identifier for a Midjourney-style creative upscaling endpoint. Based on the available public model listing and Midjourney’s official documentation, this model is designed to take an already generated image and upscale it using the Creative mode, which increases resolution while also inventing or refining visual details instead of strictly preserving every original pixel relationship.

In practice, this makes mj-fast-upscale-creative a good fit when you already have a candidate image you like, but you want a larger and more polished version with richer textures, finer details, or slight visual improvements. Midjourney explicitly notes that Creative Upscale can alter the image somewhat as it adds details, and repeated creative upscales can produce slightly different results.

Compared with a conservative upscale pipeline, this model is better understood as a detail-generating upscale rather than a purely faithful enlargement tool. That makes it especially useful for stylized art, concept imagery, fantasy scenes, and other outputs where a small amount of reinterpretation is acceptable or even beneficial. This characterization is an inference drawn from Midjourney’s description of Creative Upscale behavior.

Main features of mj-fast-upscale-creative

• Creative detail enhancement: Adds or refines details during upscaling instead of only enlarging the existing image, which can make outputs feel richer and more finished.
• Resolution increase: In current Midjourney documentation, Creative Upscale doubles the size of the original image, such as 1024×1024 to 2048×2048 for square outputs.
• Image-to-image finishing workflow: Best used after an initial generation step, when you have already chosen the image you want to promote to a higher-quality final asset.
• Useful for stylized outputs: Because Creative Upscale may reinterpret small elements, it is well suited to artistic and illustrative images where added embellishment is a feature rather than a drawback. This is an inference from Midjourney’s documented behavior.
• Potential correction of minor issues: Midjourney notes that Creative Upscale can sometimes help improve small visual problems, such as awkward hands or facial issues.
• Consistent CometAPI access: CometAPI exposes the model as mj-fast-upscale-creative, allowing developers to work with it through CometAPI’s unified model access layer.
• Per-request pricing model: The public CometAPI listing shows request-based pricing, which is useful for predictable integration and usage accounting.

How to access and integrate mj-fast-upscale-creative

Step 1: Sign Up for API Key

Sign up on CometAPI and create your API key from the dashboard. Once you have an active key, you can authenticate your requests to the unified API and call mj-fast-upscale-creative just like any other model on the platform.

Step 2: Send Requests to mj-fast-upscale-creative API

Send a request to the CometAPI endpoint using your API key and set the model field to mj-fast-upscale-creative.

curl --request POST \
  --url https://api.cometapi.com/v1/responses \
  --header "Authorization: Bearer $COMETAPI_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "model": "mj-fast-upscale-creative",
    "input": [
      {
        "role": "user",
        "content": [
          {
            "type": "input_text",
            "text": "Upscale the selected Midjourney image with creative enhancement."
          }
        ]
      }
    ]
  }'

Step 3: Retrieve and Verify Results

Parse the API response and verify that the returned output matches your expected upscale task. In production, you should also log request IDs, store returned asset metadata, and confirm that the generated image resolution and creative changes are acceptable for your workflow.
