Seedream 4.5 improves realism, lighting control, and prompt precision for visual storytellers.
Seedream 4.5 introduces stronger realism and more reliable scene structure. The focus is creative freedom: you can shape lighting, maintain consistency, and build visual narratives with fewer technical constraints.
The model is more responsive to precise prompt language, which makes prompt design feel more like directing a scene than guessing outcomes.
Lighting behaves more naturally in this release. Shadows feel cleaner and reflections are more believable, which helps creators build mood with intention.
Materials show richer surface detail, so environments feel more cohesive across a sequence.
Seedream 4.5 keeps environments and subjects consistent over multiple shots. This is especially useful for storyboard work, pre-visualization, and extended concept exploration.
If your workflow depends on repeating a character or set, the new coherence improvements reduce drift.
The model follows complex prompts with higher precision, including weighted terms and detailed descriptors.
Generation time is faster, which makes iteration cycles shorter and more productive for professional teams.
