Model Overview

A powerful image generation and editing model that supports text-to-image, image-to-image, and inpainting with masks and reference inputs — all guided by a text prompt.

How to Make a Call

Step-by-Step Instructions

1️ Setup You Can’t Skip

▪️ Create an Account: Visit the AI/ML API website and create an account (if you don’t have one yet). ▪️ Generate an API Key: After logging in, navigate to your account dashboard and generate your API key. Ensure the key is enabled on the UI.

2️ Copy the code example

At the bottom of this page, you'll find a code example that shows how to structure the request. Choose the code snippet in your preferred programming language and copy it into your development environment.

3️ Modify the code example

▪️ Replace <YOUR_AIMLAPI_KEY> with your actual AI/ML API key. ▪️ Adjust the input field used by this model (for example, prompt, input text, instructions, media source, or other model-specific input) to match your request.

4️ ^_(Optional) Adjust other optional parameters if needed

Only the required parameters shown in the example are needed to run the request, but you can include optional parameters to fine-tune behavior. Below, you can find the corresponding API schema, which lists all available parameters and usage notes.

5️ Run your modified code

Run your modified code inside your development environment. Response time depends on many factors, but for simple requests it rarely exceeds a few seconds.

If you need a more detailed walkthrough for setting up your development environment and making a request step-by-step, feel free to use our Quickstart guide.
