• Image-to-Image (img2img): Generates new images based on existing images and prompts.
• Outpainting: Extends image boundaries.
• Inpainting: Repairs or replaces specific areas of an image.
• Color Sketch: Generates images based on color sketches.

Advanced Features

• Prompt Matrix: Batch tests different prompt combinations.
• Stable Diffusion Upscaling: Uses AI for image super-resolution.
• Attention Control: Controls the model's attention to specific words through parentheses and weights.
• Loopback: Runs img2img processing multiple times.
• X/Y/Z Plotting: Generates three-dimensional image comparison charts with different parameters.

Textual Inversion and Training

• Textual Inversion: Trains custom embeddings.
• Hypernetworks: Trains network modifications.
