What is the recommended approach for using prompts with Stable Diffusion 2.1?
-It is recommended to start with simple prompts and a moderate number of steps, adjusting as needed based on the results. It's also suggested to experiment with different prompts and not rely solely on higher steps for better images.
How can users who prefer not to use a GUI access Stable Diffusion 2.1?
-Users who prefer not to use a GUI can access Stable Diffusion 2.1 directly from the diffusers Library by changing the model ID and installing stable diffusers from GitHub.
What is the significance of the removal of adult content and certain artists from the training dataset?
-The removal of adult content and certain artists is significant as it helps improve the quality of generated images, particularly in terms of anatomy, and reduces the necessity for using negative prompts.
How does the new Stable Diffusion 2.1 model handle celebrity images?
-Stable Diffusion 2.1 has improved its handling of celebrity images, enabling the generation of superhero images and addressing previous complaints about the original celebrity pictures.
What is the recommended way to support the creator of the Stable Diffusion UI?
-The recommended way to support the creator of the Stable Diffusion UI is by buying them a coffee or supporting them with GitHub Stars if you are using the notebook extensively.
Outlines
