Released on November 9, 2026, Seedream 5.5 is ByteDance Seed's next-generation image creation model engineered for professional visual production workflows. Supporting 1K, 1.5K, and 2K resolutions (2K default, no 4K), it allows 1 to 10 reference images to maintain character, product, and style consistency. The model delivers three major technical breakthroughs: up to 100 rounds of pixel-level, non-destructive multi-turn editing without color drift; native RGBA transparent background generation in PNG format; and high-accuracy text rendering across 15+ languages including Chinese and English.
