Transforming Basic Inputs into Incredibly Realistic Images with Stable Diffusion

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.

We'll also see how we can use Replicate Codex to find similar models and decide which ones suit our specific needs per time.

Let's begin.

About the Stable Diffusion Realistic Vision Model

Stable Diffusion Realistic Vision (realist_vision_v1.3), 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.

Step 1: Set Up Your Environment

First, install the necessary Node.js package:

npm install replicate

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

export REPLICATE_API_TOKEN=[token]

Step 2: Run the Model

Now, run the model with your desired input parameters:

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.

The input image and resulting output in Image-to-Image mode.

The output variable will contain an array of image URLs generated by the model.
