Tags telling the model what NOT to include. Crucial in Stable Diffusion to fix hands, blur, watermarks.
Prompt Weighting
Adjusting emphasis on specific tokens, e.g. (red dress:1.5) in Stable Diffusion.
CFG Scale
Classifier-Free Guidance — controls how strictly the model follows your prompt. Higher = stricter.
Seed
Random number that determines the noise pattern. Same prompt + same seed = reproducible image.
Inpainting
Masking a region of an image and regenerating just that area while keeping the rest.
Outpainting
Extending an image beyond its original borders, generating new content that matches the existing scene.
