Reference Images — How They Work
Reference images let you communicate visually with the model. Here are common use cases:
- Style Transfer: Upload artwork or photos with the aesthetic you want — the model adopts similar colors, lighting, and mood.
- Character Consistency: Feed in multiple angles of the same character to generate new poses or scenes while keeping the look consistent.
- Product Shots: Provide photos of your product from different angles. The model can place it in new environments or lighting setups.
- Mood Boards: Upload a collection of images that capture the vibe you're after. Seedream 4.5 synthesises these into a cohesive result.
The more reference images you provide, the more context the model has to work with. You can use anywhere from 1 to 14.
