ByteDance released Seedream 5.5 on November 9, 2026. ByteDance lists four main upgrades: edits that keep the rest of the image unchanged across many rounds, native transparent PNG output, sharper small and non-English text, and more natural skin, lighting and materials. On ImagesArt a 1K image costs 4 credits, compared with 7 for Seedream 5.0 Pro.

Open the settings and set Background to Transparent. The model then returns a PNG with an alpha channel. It works best for single subjects such as stickers, logos, icons and product shots. Paid plans download the original PNG; free downloads carry a watermark and are saved as WebP, which keeps the transparency.
