What it means
Most text-to-image diffusion models initialize with random latent noise, so identical descriptive prompts produce entirely different faces each time. Prompts alone cannot maintain facial geometry across sessions; consistency requires feeding the model persistent reference data of the person.
On AIGE, a character is a saved record with a name, an avatar and a gallery of reference photos. Every image or video you generate with that character selected carries its ID and photos to the model, so the face holds while the outfit, setting, lighting and pose change.
For video, the same saved character is passed to video generation, and image-to-video (i2v) can start a clip from a still of that character with Kling 3.0, Veo 3.1 or Seedance, so the person in your clips matches the person in your images.
It is a strong anchor, not a lock: extreme angles or heavy stylization can still shift small details. The same character carries into video and the Fitting Room, so you build the identity once and reuse it everywhere.

Frequently asked questions
Why does my AI character's face change between images?
Most generators treat every prompt as a fresh start from random noise seeds, with no memory of previous generations. Reusing a persistent gallery of reference photos attached to a character ID is what anchors the facial identity across generations.
Can prompt engineering alone fix character drift?
No. Detailed descriptions can specify styling, clothing or hair color, but diffusion models cannot derive consistent facial bone structure from text alone. Physical reference photos or identity embeddings are required to hold the face.
Does character consistency work across video models too?
On AIGE, yes. The same saved character is passed to video generation, and image-to-video can start a clip from a still of that character, so the person in your clips matches the person in your images.
How many reference photos do I need for good consistency?
A few clear, well-lit photos are enough to start. You can keep adding photos to the character's gallery over time.
