Seedream 5.5

ByteDance's Seed team introduced Seedream 5.5, an image model focused on stable multi-turn editing, transparent-background output and more realistic images.

Announced on ByteDance Seed's blog on Nov 9. The team highlights three upgrades: multi-turn editing that keeps unedited regions unchanged at the pixel level across up to 100 rounds of edits, native RGBA output with full or partial transparency so generated elements can be used directly as assets, and more natural lighting, skin and material rendering with clearer small and complex text. ByteDance says its evaluations show leading results in text structure and text-to-image realism; those are the company's own figures. A Pro version of the Seedream 5.5 series is promised later. The post does not detail pricing or which ByteDance products get it first.
