Ever fantasized about designing a unique Pokémon that springs straight from your imagination to the computer screen? Get ready to be amazed, as we're about to turn that dream into reality with the incredible power of AI!
Are you prepared to embark on this thrilling creative adventure? Let's go!
In this beginner-friendly guide, I'll walk you through how to generate your own Pokémon from text using an AI model created by Lambdal called "text-to-pokemon." This model is one of the most popular models on Replicate!
Text-to-Pokemon comes in at #8 on our leaderboard at the time of this writing.
We'll learn how to interact with the model via Replicate's UI and via Python, and understand how it works and how we can tweak it to fit our needs.
We'll also see how we can use Replicate Codex to find similar models and decide which one we like. Let's begin.
About the Text-to-Pokemon Model
The text-to-pokemon model is a diffusion fine-tuned AI model designed to generate Pokémon characters from a text description. With over 6.2 million runs, this AI model has gained popularity among Pokémon fans and creative minds alike. It's the 8th-most popular model on Replicate and costs about $0.011 per run on replicate.
You can learn more about the model and its creator by visiting the Replicate Codex link. It's also open source and you can run it on your own computer.
Wait, what's a diffusion model?
In beginner terms, a diffusion model is a way to create new content, such as images or text, using artificial intelligence. It works by starting with an image and adding random noise (like static on a TV screen). Then, the AI gradually transforms the image into a meaningful output by removing the static, like an image or text, based on the input or prompt given.

It studies the steps it used to recreate the original and learns patterns from it. Then, when you ask it to create a variation, it modifies its steps a bit to give a new image.
Ok! Now that we know what we're dealing with, let's dive into the step-by-step guide on how to interact with the text-to-pokemon API on Replicate. First, we'll take a look at the model inputs and outputs and what they mean.
Understanding the Inputs and Outputs of the Text-to-Pokemon Model
Before diving into the details, let's take a closer look at the various inputs and outputs of the text-to-pokemon model and understand their acceptable values. We'll also explore different scenarios where you might want to change these values.
Inputs
prompt (string): This is the text description you provide to the model to generate your desired Pokémon. You can use any creative description that helps you create the Pokémon you have in mind.
num_outputs (integer): This input determines the number of images to output. The acceptable values are 1, 2, 3, or 4. You may want to increase this value if you'd like to generate multiple Pokémon images from the same text prompt, giving you more options to choose from.
num_inference_steps (integer): This input controls the number of denoising steps. The default value is 25, and the acceptable range is 1 to 50. Increasing this value can improve the quality of the generated image, but it might also increase the processing time. You can experiment with this value to find the balance between image quality and processing time that works best for your needs.
guidance_scale (number): This input controls the scale for classifier-free guidance. The default value is 7.5, and the acceptable range is 1 to 20. A higher guidance_scale value may result in stronger guidance for the model to follow the text prompt, but it could also lead to more artifacts in the generated image. You can adjust this value to find the right balance between text guidance and image quality.
seed (integer, optional): This input sets the random seed. If left blank, the seed will be randomized. Using the same seed with the same input parameters will produce the same image, allowing you to reproduce your results. You might want to set a specific seed if you're trying to compare different settings of the model or share your work with others who can reproduce your exact results.
Outputs
The output of the text-to-pokemon model is an array of image URIs. The number of images in the array corresponds to the num_outputs input value. Each image in the array is a unique Pokémon generated based on the text prompt and other input parameters you provided.
The output schema for the model is as follows:
{
"type": "array",
"items": {
"type": "string",
"format": "uri"
},
"title": "Output"
}

Now that you have a better understanding of the inputs and outputs of the text-to-pokemon model, you can more effectively fine-tune the parameters to create the perfect Pokémon to suit your imagination!
Step-by-Step Guide to Generate Your Own Pokémon
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 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.
Enormously disturbing - sorry for creating this monstrosity, everyone.
If you're more technical and looking to eventually build a cool tool on top of this model, you can follow these simple steps to create your very own Pokémon using the text-to-pokemon model on Replicate.
💡
Be sure to create a replicate account first! You'll need your API key for this project.
Step 1: Install the Replicate Python Client
First, you'll need to install the Replicate Python client from PyPI. Run the command below to install the client:
pip install replicate
Installing the client
Step 2: Set up API Token
Copy your API token and authenticate by setting it as an environment variable:
export REPLICATE_API_TOKEN=[token]
Setting an env variable
If you can't find your API token, you can access it by clicking on the "Account" tab in the top right of any page on the Replicate site.
Step 3: Run the Model with Your Inputs
Now, you're ready to run the model using just a few lines of code:
import replicate
model = replicate.models.get("lambdal/text-to-pokemon")
version = model.versions.get("3554d9e699e09693d3fa334a79c58be9a405dd021d3e11281256d53185868912")
inputs = {
'prompt': "", # Add your text prompt here
'num_outputs': 1,
'num_inference_steps': 25,
'guidance_scale': 7.5,
}
output = version.predict(**inputs)
print(output)
Running the Replicate model.
This is the beauty of Replicate - look how quick and easy it was to set this up 😎
Replace the empty string in the prompt input with your desired text description, and you're good to go! The result will be available at the "URI" in the output. Here’s what I got for the prompt “Sonic the Hedgehog as a pokemon” with the default parameters.
Not too bad!
