A quietly excellent frontier model — especially strong on realistic people and multilingual text.
Seedream is ByteDance's frontier image model, and it punches at the top tier on raw fidelity — particularly photorealistic people and scenes. It also handles multilingual text, including Chinese, better than most Western models, and it's priced aggressively. Access is the catch for Western teams: it lives mainly behind Volcengine and consumer apps like Dreamina rather than a friendly global API.
