Picsart adds Seedream 5.5 for stable multi-step image editing
Picsart has added ByteDance Seedream 5.5 to its AI Playground, bringing multi-step image editing, native transparent backgrounds and improved image realism to the platform. ByteDance Seed announced the model on November 9, 2026, as the follow-up to its Seedream 5.0 line.
- Seedream 5.5 is now available in Picsart’s AI Playground.
- The model supports multi-turn editing designed to preserve untouched areas.
- It can generate PNG images with transparent and semi-transparent backgrounds.
- Users can choose up to 10 source images, multiple resolutions and seven aspect ratios.
- ByteDance says a Pro version of Seedream 5.5 will follow.
Designed to preserve images through repeated edits
Seedream 5.5 can generate an image from a written prompt or edit an uploaded photo. According to Picsart, its main distinction is stable multi-turn editing: areas that are not selected for changes are protected at the pixel level, helping preserve colors, faces, lighting and backgrounds from one edit to the next.
ByteDance tested the approach by putting a single portrait through 100 consecutive edits, using each output as the input for the next change. After modifications involving clothing, accessories and objects, the model could still edit small details such as a ring or glasses while keeping skin contact, shadows and lighting consistent with the pose. Picsart also describes a room makeover demonstration in which perspective, shadows and the floor beneath a moving box remained believable as the room changed.
Transparent output and more realistic details
Seedream 5.5 can produce PNG images with an alpha channel, including fully clear and semi-transparent areas. Users can select a transparent background mode so the subject arrives already separated from its background. Picsart highlights a snowy owl example in which feather tips, gaps between the wings and the outline of the claws remain visible without a separate cleanup pass.
The feature is aimed at practical design tasks such as stickers, product cutouts, styled lettering and reusable character assets. The model also focuses on more realistic light, skin texture and materials. Picsart points to examples including a backlit portrait with illuminated strands of hair and a race car on a wet track with tire spray obscuring vehicles behind it.
Small text is another target. According to Picsart, Seedream 5.5 can handle dense lettering in English and Chinese, including newspaper-style pages and infographics with small captions. That could reduce the need to regenerate posters, labels and editorial layouts when letters become distorted.
Settings and access in Picsart
Seedream 5.5 is available in Picsart’s AI Playground through the browser or desktop app, alongside more than 150 other models. Users can choose 1K, 1.5K or 2K resolution, with aspect ratios of 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, 2:3 and 21:9. The tool supports up to 10 source images, which can be used for editing or as guides for a subject, style or composition.
Other controls include negative prompts and automatic, transparent or opaque backgrounds. Picsart recommends making one change at a time and continuing to edit the latest result. Seedream 5.0 Pro remains available for high-end single images, while ByteDance says a Pro version of Seedream 5.5 will follow.
In ByteDance’s evaluations across e-commerce, marketing, film and television, gaming, office work and fashion design, Seedream 5.5 scored higher than 5.0 Pro in every area. Picsart says the share of usable images more than doubled in film and television and in office work. For users, the release offers a workflow built around refining one image over several rounds, rather than restarting when edits begin to affect unrelated details.
