The Challenge of Consistency
Getting AI to generate the same character across multiple images is one of the most requested features.
Method 1: Reference Images
Use reference images with image-to-image models and strength 0.5-0.7.
Method 2: Face Embeddings
Extract and inject face embeddings for more precise control.
Method 3: LoRA Fine-Tuning
For production use, fine-tune a LoRA with 15-30 character images.
Comparison
| Method | Consistency | Speed | Cost |
|---|---|---|---|
| Reference | 70% | Fast | Low |
| Embeddings | 85% | Fast | Low |
| LoRA | 95%+ | Medium | Higher |
Best Practices
- Establish a "Character Sheet" with multiple angles
- Use consistent style keywords
- Control seeds for similar compositions
- Run face enhancement as post-processing
