Controlnet-scribble is one of the most popular models on Replicate Codex.

About the ControlNet Scribble Model

ControlNet Scribble is an image-to-image AI model created by the developer jagilley. As mentioned earlier, it can take your rough sketches and turn them into highly detailed images. This model uses a technique called deep learning, which involves training the model on large amounts of data to allow it to learn patterns and relationships within the data. ControlNet Scribble is based on a neural network architecture that has been optimized to produce high-quality outputs.

According to the Replicate Codex website, ControlNet Scribble is ranked at 5 out of all the models on the platform. This means that it is a popular and widely used model that has been highly rated by its users. Additionally, its creator jagilley is ranked 3 out of all the creators on the platform, making them a highly respected and experienced developer in the AI space.

Understanding the Inputs and Outputs of ControlNet Scribble


ControlNet Scribble requires the following inputs:

  • An image file: This is the sketch or scribbled drawing that you want to turn into a detailed image.
  • Prompt string: This is a short phrase or sentence that provides additional information or context about the image you want to generate.
  • Num_samples: This parameter specifies the number of samples to generate. Higher values may cause out-of-memory errors.
  • Image_resolution: This parameter specifies the image resolution to be generated.
  • Ddim_steps: This parameter sets the number of steps for the optimization process.
  • Scale: This parameter sets the guidance scale.
  • Seed: This parameter sets the seed for the random number generator.
  • Eta: This parameter sets the eta for DDIM.
  • A_prompt: This parameter specifies the added prompt.
  • N_prompt: This parameter specifies the negative prompt.


The output of ControlNet Scribble is an array of image URLs that represent the detailed images generated from the input sketches.

A Step-by-Step Guide to Using ControlNet Scribble

If you want to use ControlNet Scribble, you can interact directly with the model's demo on Replicate via their UI. You can use this link to interact directly with the interface and try it out! Alternatively, you can use the Replicate API to run the model.

Here's a step-by-step guide to using ControlNet Scribble via the Replicate API:

Step 1: Install the Replicate Node.js Client

First, you need to install the Replicate Node.js client. You can do this using the following command:

npm install replicate

Step 2: Authenticate with Your API Token

Next, you need to authenticate with your API token. You can do this by setting your API token as an environment variable:

export REPLICATE_API_TOKEN=[token]

Step 3: Run the Model

Finally, you can run the model using the following code:

import Replicate from "replicate";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,

const output = await
    input: {
      image: "path/to/your/image/file",
      prompt: "a short phrase or sentence that describes your image",
      num_samples: "1",
      image_resolution: "512",
      ddim_steps: 20,
      scale: 9,
      seed: 0,
      eta: 0,
      a_prompt: "best quality, extremely detailed",
      n_prompt: "longbody, lowres, bad anatomy, bad hands, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality"

You can specify the path to your input image file, as well as the prompt and other parameters, in the input object. Once you run the model, the output will be an array of image URLs that you can use to view the generated images.

If you're not comfortable with coding, you can still use ControlNet Scribble via the demo link provided earlier. The UI is user-friendly and allows you to input the necessary parameters and generate images without any coding.
