In this guide, I will introduce you to the Dalle-Mega model, ranked #190 on [AIModels.fyi](http://AIModels.fyi), that takes a text prompt as input and generates an image. I will explain how the model works, its inputs and outputs, and guide you step-by-step to use it effectively. Additionally, we'll explore how you can utilize [AIModels.fyi](http://AIModels.fyi) to find similar models, helping you make informed decisions. Ready to unlock your creativity? Let's begin!

## About the Dalle-Mega

Dalle-Mega, created by [Nicholas Celestin](https://aimodels.fyi/creators/replicate/nicholascelestin), is an AI model that uses the power of AI to generate images from text prompts. The model uses an Nvidia T4 GPU to run and has an average completion time of 45 seconds per run. The cost per run is $0.02475 USD. Despite its relatively recent introduction, Dalle-Mega has already been run 11,840 times. To learn more about the model, visit the [model's detail page](https://www.aimodels.fyi/models/replicate/461e13fc-277d-4e9c-9329-bcc9aaaceb13).

Despite the availability of the Dalle-Mega model, the creator recommends using the Dalle-Mini model instead, deeming it superior. Dalle-Mini is a smaller and faster version of the model, and there is an implementation by Boris Dayma available on Replicate. It can be accessed [here](https://www.aimodels.fyi/models/replicate/be944dfa-3f3c-4536-b335-5cc553e38be8), and functions similarly to the Dalle-Mega model.

## Understanding the Inputs and Outputs of the Dalle-Mega

Before we jump into how to use Dalle-Mega, it's essential to understand what goes in and what comes out of it.

### Inputs

The model takes two inputs:

* `prompt` (string): This is the text or idea that you want to transform into an image.
    
* `num` (integer): This specifies the number of images to generate. Its default value is 1.
    
* `model_size` (string): Specifies the size of the model. The allowed value for this is MINI.
    

### Outputs

The model's output is an array of strings, where each string is a URI of the generated image.

Now that we understand what Dalle-Mega needs and returns, let's dive into how to use it.

## A Step-By-Step Guide to Using Dalle-Mega

For those who prefer a hands-off approach, you can interact directly with the Dalle-Mega's demo on Replicate via its UI. This link to the [demo](https://replicate.com/nicholascelestin/dalle-mega/examples) allows you to interact directly with the interface, playing with the model's parameters, and getting quick feedback. However, if you're more of a hands-on coder, the following guide will show you how to interact with the model's Replicate API.

### Step 1: Installation

Start by installing the Node.js client:

```markdown
npm install replicate
```

### Step 2: Authentication

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

```markdown
export REPLICATE_API_TOKEN=r8_*************************************
```

### Step 3: Running the Model

Then, run the model:

```markdown
import Replicate from "replicate";

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

const output = await replicate.run(
  "nicholascelestin/dalle-mega:70dbc2347bdc08d78af32a0fca8c1cafd3a6a7c29ea2bfa5a2fbbf0e70a1e1b8",
  {
    input: {
      prompt: "..."
    }
  }
);
```

You can also set a webhook URL to be called when the prediction is complete:

```markdown
const prediction = await replicate.predictions.create({
  version: "70dbc2347bdc08d78af32a0fca8c1cafd3a6a7c29ea2bfa5a2fbbf0e70a1e1b8",
  input: {
    prompt: "..."
  },
  webhook: "https://example.com/your-webhook",
  webhook_events_filter: ["completed"]
});
```

This allows you to receive updates about your prediction.
