Have you ever wished you could just describe an image to your computer and have it magically appear before your eyes? Or turn a low-quality avatar or sketch into a high-quality shot with your face on it? Well, now you can! Stable Diffusion Realistic Vision is an AI model that produces incredibly realistic images based on your descriptions or input pictures. It can transform even the most basic inputs into realistic photos. Neat!

In this guide, we'll walk you through how to use this model in your browser, and then how to take it even further with LoRAs. Ranked 64 on Replicate Codex, this model is a powerful tool you'll definitely want in your creative arsenal.

## About the Stable Diffusion Realistic Vision Model

Stable Diffusion Realistic Vision ([realistic\_vision\_v1.3](https://www.replicatecodex.com/models/4?ref=notes.replicatecodex.com)), created by cloneofsimo, is an image-to-image AI model that generates stunningly realistic images from textual descriptions. It leverages the power of Stable Diffusion, a latent text-to-image diffusion model, to create photorealistic images from any text input.

LoRAs, or Learned Robust Artistic Styles, are files that can be applied to existing Stable Diffusion models to produce images based on specific concepts like art styles, characters, real-life people, objects, or themes. By combining the Stable Diffusion Realistic Vision model with LoRAs, you can create unique, personalized images tailored to your needs and preferences.

## Understanding the Inputs and Outputs of the Stable Diffusion Realistic Vision Model

### Inputs

The model requires a few inputs to generate an image:

1. **prompt**: A text description of the image you want to create. Use `<1>`, `<2>`, `<3>`, etc., to specify LoRA concepts.
    
2. **negative\_prompt**: (Optional) Specify things you don't want to see in the output.
    
3. **width** and **height**: Dimensions of the output image. Maximum size is 1024x768 or 768x1024 due to memory limits.
    
4. **num\_outputs**: Number of images to output.
    
5. **num\_inference\_steps**: Number of denoising steps.
    
6. **guidance\_scale**: Scale for classifier-free guidance.
    

### Outputs

The model will output an array of image URLs, one for each generated image.

Now that we understand the inputs and outputs, let's dive into how to use the model to create mind-blowing images.

## A Step-by-Step Guide to Using Stable Diffusion Realistic Vision Model

If you're not up for coding, you can interact directly with this model's "demo" on Replicate via their UI. You can use [this link](https://replicate.ai/cloneofsimo/realistic_vision_v1.3https://www.replicatecodex.com/models/4?ref=notes.replicatecodex.com) to interact directly with the interface and try it out! This is a nice way to play with the model's parameters and get some quick feedback and validation.

### Step 1: Set Up Your Environment

First, install the necessary Node.js package:

```bash
npm install replicate
```

Then, copy your API token and authenticate by setting it as an environment variable:

```bash
export REPLICATE_API_TOKEN=[token]
```

### Step 2: Run the Model

Now, run the model with your desired input parameters:

```javascript
import Replicate from "replicate";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,
});
const output = await replicate.run(
  "cloneofsimo/realistic_vision_v1.3:db1c4227cbc7f985e335b2f0388cd6d3aa06d95087d6a71c5b3e07413738fa13",
  {
    input: {
      prompt: "a photo of <1> riding a horse on Mars",
      width: 512,
      height: 512,
      num_outputs: 1,
      num_inference_steps: 50,
      guidance_scale: 7.5
    }
  }
);
```

Replace `<1>` with a specific LoRA concept if you want to customize the image even more. You can also adjust the other parameters as needed.

Recall from above that you can also provide an **image** input value. If you supply a file as an input argument for that field, the Image-to-Image mode will be invoked. You can see an example of an image-to-image run below.
