Prompting Seedream 4
- Long, specific prompts are rewarded here where they would be truncated by a faster model.
- Put the subject in the first few words — every model here weights the start of a prompt most heavily.
- Describe the lighting explicitly. It is the change that most reliably moves output towards the photographic.
- Generate at the aspect ratio you need rather than cropping afterwards, which costs you pixels and composition.
