Prompt Weighting

A technique for emphasizing or de-emphasizing specific words in an AI image generation prompt to control their influence on the output.

Prompt weighting lets users fine-tune AI image generation by assigning numerical importance to different prompt tokens. Common syntaxes include parentheses for emphasis ((word) = 1.1x, ((word)) = 1.21x) or explicit weights (word:1.5). Negative weights or negative prompts exclude unwanted elements. Effective prompt weighting addresses a common frustration: AI models don't weight all words equally, and important details can get lost. By boosting 'sharp focus:1.4' or 'golden hour lighting:1.3', users steer the generation toward specific attributes. The technique requires experimentation — too much weight creates artifacts, while too little has no visible effect. Combined with negative prompts, weighting gives precise creative control over AI outputs.
