| understands what you want.</p> <p>2. Try to use different random seeds, which can affect the generation | |
| quality significantly sometimes.</p> <p>3. It's better to use general terms like 'man' or 'woman' | |
| instead of specific names for individuals or abstract objects that humans may not be familiar with, | |
| such as 'mummy'.</p> <p>4. Using a negative prompt to not guide the diffusion process can improve the | |
