Seedream 5.5
AI image and video generator with stable multi-round editing
About Seedream 5.5
Seedream 5.5 is an AI image model from ByteDance's Seed team, offered through the Seedream55 website as a browser-based generator. It is aimed at people who work on images beyond the first draft, such as e-commerce sellers, designers and marketers who need clean edits, localized copy and assets ready for use.
According to the site, edits stay stable across more than 80 rounds, so untouched parts of an image remain in place. The model can output native transparent RGBA images, split an image into up to 100 layers, and render small text in several languages more accurately. It also supports 4K output at 16:9.
The Seedream55 site lets visitors write a prompt, pick a model and generate images or short videos without installing anything. It lists Seedream 5.0 Pro, Nano Banana, GPT Image and other models in one picker, and new accounts receive free credits. The site notes that it is independent and not affiliated with ByteDance.
