1. Your intitial text along with the prompt is sent to Llama 3 70b to generate a python dictionary.
2. This new text will populate in interactive text fields. If it isn't perfect you can edit the text to fit your item.
3. The final text field is the Stable Diffusion prompt, these generate like one sentence stories describing the scene of your item. This field can also be edited.
## The first image generation take about 2 minutes for model to 'cold boot' after that it's ~10s per image.
4. **Image and Text Generation**: Now generate 4 card template without text and pick your favorite.
5. Finally, add text to your favorite template.
3. **Result**: The final product is a beautifully crafted D&D item card, ready for use in your gaming sessions."""
