ByteDance Launches Seedream 5.5: 100+ Edit Rounds Without Drift at $0.02 per Image

On November 9, ByteDance officially released the image generation model Seedream 5.5. Its headline feature is "multi-round editing consistency": the company says a single image can undergo 100+ consecutive rounds of localized edits while unedited regions are preserved pixel-for-pixel without drift. It also natively supports RGBA transparent asset output with full/partial transparency, and improves photorealism, small-text and multilingual text rendering, and motion reference capabilities. The model is live on Dreamina (Jimeng), CapCut, and BytePlus, with BytePlus pricing at roughly $0.02 per image, around $20 per thousand.

Confirmed

Why it matters

Multi-round editing consistency has long been a pain point for image models—most produce great first images but degrade through repeated edits, which directly limits e-commerce, brand design, and other workflows requiring iterative tweaks. Multiple independent bloggers' tests corroborate that 5.5 clearly leads GPT Image and Nano Banana on this dimension; combined with the $0.02 unit price, it's highly cost-effective for iterative commercial workflows (product images, lookbooks, transparent assets).
