## Model overview

The `controlnet-scribble` model is a part of the ControlNet suite of AI models developed by Lvmin Zhang and Maneesh Agrawala. ControlNet is a neural network structure that allows for adding extra conditions to control diffusion models like [Stable Diffusion](https://aimodels.fyi/models/replicate/stable-diffusion-stability-ai). The `controlnet-scribble` model specifically focuses on generating detailed images from scribbled drawings. This sets it apart from other ControlNet models that use different types of input conditions like normal maps, depth maps, or semantic segmentation.

## Model inputs and outputs

The `controlnet-scribble` model takes several inputs to generate the output image:

### Inputs
- **Image**: The input scribbled drawing to be used as the control condition.
- **Prompt**: The text prompt describing the desired image.
- **Seed**: A seed value for the random number generator to ensure reproducibility.
- **Eta**: A hyperparameter that controls the noise scale in the DDIM sampling process.
- **Scale**: The guidance scale, which controls the strength of the text prompt.
- **A Prompt**: An additional prompt that is combined with the main prompt.
- **N Prompt**: A negative prompt that specifies undesired elements to exclude from the generated image.
- **Ddim Steps**: The number of sampling steps to use in the DDIM process.
- **Num Samples**: The number of output images to generate.
- **Image Resolution**: The resolution of the generated images.

### Outputs
- An array of generated image URLs, with each image corresponding to the provided inputs.

## Capabilities

The `controlnet-scribble` model can generate detailed images from simple scribbled drawings, allowing users to create complex images with minimal artistic input. This can be particularly useful for non-artists who want to create visually compelling images. The model is able to faithfully interpret the input scribbles and translate them into photorealistic or stylized images, depending on the provided text prompt.

## What can I use it for?

The `controlnet-scribble` model can be used for a variety of creative and practical applications. Artists and illustrators can use it to quickly generate concept art or sketches, saving time on the initial ideation process. Hobbyists and casual users can experiment with creating unique images from their own scribbles. Businesses may find it useful for generating product visualizations, architectural renderings, or other visuals to support their operations.

## Things to try

One interesting aspect of the `controlnet-scribble` model is its ability to interpret abstract or minimalist scribbles and transform them into detailed, photorealistic images. Try experimenting with different levels of complexity in your input scribbles to see how the model handles them. You can also play with the various input parameters, such as the guidance scale and negative prompt, to fine-tune the output to your desired aesthetic.
