How Agencies and Brands Keep One AI Model Consistent Across Campaigns

Quick answer: Create a reference sheet first: front, 3/4, profile and full body in neutral light. Save it as one character, reuse it in every prompt by name, keep the description short and fixed, and change only outfit, scene and light. Check face shape, eyes and hairline against the sheet after every shot.

Why faces drift

Each generation starts fresh. Long, changing descriptions and missing references let the model reinvent the face.

Step by step

1. Generate or photograph a 4-angle reference sheet.
2. Save it as a named character, for example @Mara.
3. Write a fixed identity line: age range, hair, one distinctive feature.
4. Change only clothing, scene and lighting.
5. Reject any image where the face drifts; do not fix it with more words.
6. For real people, get written consent.

Prompt to copy

@Mara, same face and hair as the reference sheet. Wearing a camel wool coat over a white shirt. Standing on a Paris street at morning, soft overcast light. 85mm, f/2.8, editorial, natural skin texture.
