Character consistency with Souls: train once, shoot forever

Reusing the same face across a whole campaign used to be the hardest problem in generative media. Souls solve it with trained identity weights — here's how.

The thing that separates a one-off generation from an actual brand is consistency — the same character, the same face, across dozens of frames. Souls are how greenbits makes a subject reusable instead of a happy accident.

What a Soul actually is

A Soul is a small set of trained weights — a LoRA — that teaches the image model what your specific subject looks like. Once it's trained, every generation that references the Soul renders that identity, not a lookalike. It's the difference between describing a person and actually casting them.

Training one

  1. Gather a handful of clear reference photos of your subject — varied angles and lighting help a lot.
  2. Start a training run from the Soul studio. greenbits bundles the images and trains the LoRA for you.
  3. Wait for the status to flip to ready — training runs in the background while you work on other things.
  4. Shoot. Pick a look, reference the Soul, and every frame comes back on-character.

Don't want to train? Use a look or a persona.

The Soul photo model also ships with art-directed looks and named personas you can shoot through immediately — no training step. Train your own only when you need a specific real identity locked across a campaign.

Where consistency pays off

  • AI influencers — one persona, an endless on-brand content stream
  • Product campaigns — the same model across every channel and aspect ratio
  • Episodic content — a recurring character that actually stays recognizable
Consistency is the unglamorous feature that quietly makes everything else look professional.

Souls also work from the API — train and shoot programmatically with the same tools your agents already call. Read about Souls or jump straight into the Soul studio.
