Why it is written this way
People looking for AI character consistency have usually already generated several images: one has curly hair, the next has straight hair, and glasses only appear in two of them. The problem isn't the AI's memory—it is subtle variations in how the human writes each prompt. If a single descriptive word is omitted, the AI imagines that detail from scratch.
Task: The anchor prompt functions as a character specification sheet. Fixing the sequence from age to accessories ensures that missing elements can be spotted instantly at a glance. Explicitly reporting any default values added by the AI is crucial; quietly assumed traits tend to shift unexpectedly in subsequent scenes.
Splitting the generation scene by scene is intentionally deliberate. Asking for "four scenes at once" causes the AI to abbreviate or summarize the anchor prompt as it progresses. Requiring a log of what is newly decided per scene makes it easy to trace exactly where a deviation started.
Self-Check: Asking the AI to review its own output catches hidden contradictions in the latter half of the prompt before the user runs it. Constraints: Barring celebrity lookalikes keeps results original, while explicitly logging necessary environmental adaptations (like an umbrella in the rain) prevents the AI from accidentally altering unlinked traits like hair color.

Compared with a bad example
Create 4 prompts for a 20s female photographer with glasses in these scenes: dawn bus stop, market, rooftop, convenience store
This brief request yields four prompts, but character descriptions degrade line by line. The first line might include glasses and the green jacket, but by line four, it degenerates into just "a young woman photographer." The resulting images will show four different people with varying hair lengths and outfits, forcing you to reread everything from scratch to diagnose the shift.
Variations
Adding New Scenes to an Existing Anchor
I want to continue using our previously established character anchor prompt. Keep the anchor prompt unchanged and generate prompts only for the new scenes listed in {{required scenes list}} using the exact same format. If any new scene overlaps in setting or camera angle with previous scenes, point it out and suggest a one-line alternative to keep the shots distinct.
Projects often span multiple days. Pasting only the established anchor prompt ensures newly added scenes maintain exact character continuity.
When Facial Features Keep Shifting
Even with the anchor prompt, the character's facial features vary across scenes. The base appearance is still "{{character appearance}}". Based on this description, rewrite only the facial detail section of the anchor prompt with greater precision. Add specific, identifiable facial markers (face shape, eye shape and spacing, eyebrows, nose structure, skin tone) as concise noun phrases, keeping the total length under two lines. Provide a brief summary explaining which descriptors were added and why.
The face is the most prone to drifting. This variant densifies facial descriptors without altering the rest of the character's setup.
Model notes
Some tools support using previously generated images as image prompts/character references or reusing fixed seed values. When available, combine those features with this anchor prompt for maximum consistency.
