Depending on the age of a person you require, some obvious choices:
- newborn, baby, toddler, x-th grader, middle/high-schooler, (pre) adolescent, teen(ager), tween, x-something, middle-aged, elderly, ancient, etc., optionally combined with early/late (though 'late ancient' must be minutes before death).
- x aged girl/woman/female, be careful though, as 'aged' also means 'grown old'.
- use old/young only if you're out of options (or just don't care).
- don't mix human speech/slang/street-talk with proper grammar/spelling.
- assume AI is stupid, just an algo traversing statistics and weight values.
Yah, the perks of the English language disambiguity will require you to be quite specific in your prompts. Using a dash (-) between words worked for SD, but Flux can be quite quirky (using the '-' as a negatory?).
Additionally, the t2i-framework-plugin-v2 [brain] button (, which uses the ai-text-plugin) does wonders for none-native English people like me.
FYI: use 'guy' for male versions as 'man' usually yields a hairy body builder with a 'wishful-thinking' reproductive organ.
