#### Parameter
- **Input Text**: For long prompts, only the first 64 text tokens will be used to generate the image.
- **Grid Size**: Size of the image grid. 3x3 takes about 15 seconds.
- **Seamless**: Tile images in image token space instead of pixel space.
- **Temperature**: High temperature increases the probability of sampling low scoring image tokens.
- **Top-k**: Each image token is sampled from the top-k scoring tokens.
- **Super Condition**: Higher values can result in better agreement with the text.
