Awesome

This PHP script uses AI to generate new, random Pokemon cards by using

• GPT to generate a name and description
• Stable Diffusion to create a visual
• Pokémon TCG for accurate moves sets
• PokeApi for accurate element types

First of all, thanks to Jack for the amazing work on the Python equivalent of this repository. I was inspired by his creativity to generate Pokémon cards out of thin air, although I came up with a slightly different approach.

Comparison

Installation

> git clone git@github.com:robiningelbrecht/pokemon-card-generator.git
# Build docker containers
> docker-compose up -d --build
# Install dependencies
> docker-compose run --rm php-cli composer install

Configuration

For this script to work you'll need two different API keys

OpenAI

• Set up an OpenAI account by navigating to https://beta.openai.com/signup
• Create an API key on https://platform.openai.com/account/api-keys

Replicate.com

• Set up a Replicate account by navigating to https://replicate.com/signin
• Copy your API key from https://replicate.com/account

The model used for generating visuals is OpenJourney. It's a Stable Diffusion model fine-tuned on Midjourney v4 images.

_{Both accounts have free tiers at first, but after a while you will need to enter credit card details. It'll cost you around 1-2 cents to generate a card.}

.env

Copy .env.dist and rename to .env, it should at least contain following info:

OPEN_AI_API_KEY=your-open-ai-api-key
REPLICATE_API_KEY=your-replicate-api-key

Generate your first card

At this point, you should be locked and loaded to generate your first Pokémon card by running

> docker-compose run --rm php-cli bin/console app:card:generate

Your CLI should output something along the lines of

You'll be able to view your card and all information used to generate it, by navigating to the card gallery page: http://localhost:8080/.

-c, --creature        The creature the Pokémon needs to look like (e.g. monkey, dragon, etc.). Omit to to use a random one
-e, --evolutionSeries Indicates if you want to generate a series that evolve from one another. Options "size", "rarity" and "numberOfCards" will be ignored
-x, --numberOfCards   The number of cards to generate. A number between 1 and 10 [default: 1]
-f, --fileType        The image file type you want to use. Valid options are svg, png [default: "png"]

-h, --help            Display help for the given command. When no command is given display help for the list command

<sub>The PNG slightly differs from the SVG because the latter allows for more flexibility while generating the image<sub>
