Seedream 4.5
ByteDance's detail-focused image model — sharper textures, stronger edits, and reference-guided polish for hero visuals.
About this model
Seedream 4.5 is ByteDance's fidelity-oriented image model, tuned for polished creative output where texture, edge detail, and reference adherence matter more than raw speed. It handles multi-reference workflows well — keeping product geometry and color consistent across angles — and balances generation speed with quality suitable for design review cycles. On HiArt it sits between Seedream 5.0 Lite (volume) and GPT Image 2 (typography-heavy layouts).
