Seedream 5.5

Seedream 5.5 is ByteDance's November 2026 image model for generating and editing images with natural language. It focuses on pixel-level precise edits that stay stable over many rounds, native transparent (RGBA) assets, denser small text and more natural photoreal light and skin. GoEnhance does not offer Seedream 5.5 yet. The creation console below uses Seedream 5.0 Pro, so you can start making images with the Seedream line today.

What's New in Seedream 5.5

Pixel-Level Edits That Survive 100+ Rounds

ByteDance says Seedream 5.5 was specially trained so that only the area you ask to change actually changes. In its tests, an image edited more than a hundred times in a row, each round starting from the previous result, kept the subject, composition and lighting outside the edited area intact. That makes long edit sessions, like trying outfits on one model or redecorating one room, far more practical. The sample shown is a Seedream 5.0 Pro edit that keeps a character's design while changing the scene.

Denser, More Accurate Small Text

Seedream 5.5 improves how it generates and lays out dense small text and complex glyphs. ByteDance shows a full newspaper page with several columns of small English text, and the Jimeng user guide claims about 95% accuracy for small text in complex scenes. Menus, price lists, infographics and packaging copy are where this matters most. The menu sample shown here was made with Seedream 5.0 Pro.

More Natural Photoreal Portraits

Compared with Seedream 5.0 Pro, ByteDance says 5.5 renders light, materials and skin texture more like a real camera, with far less of the oily, over-exposed look AI portraits often have. Backlit faces keep a dark but readable front with natural rim light on hair and shoulders, and added elements like fire or fog blend into the scene more believably. The portrait shown is a Seedream 5.0 Pro example.

Bilingual Posters and Layout

Seedream has long been strong at Chinese and English typography in one image, and 5.5 keeps headline, subtitle and small caption readable in a balanced layout. Early testers found it spelled hard Chinese characters correctly where other models failed. For best results, give every word of on-image text in quotes and say where it goes. The tea poster shown was made with Seedream 5.0 Pro.

Native Transparent Assets

Seedream 5.5 can output images with a real alpha channel and split a picture into up to 100 transparent layers. Logos, icons, stickers, product cut-outs and characters come out without a background, and semi-transparent glass or fabric keeps clean edges, so there is no separate cut-out step.

Transparent Background on Request

Besides a transparent background switch, mentioning a transparent background, a transparent PNG, no background or an alpha channel in your prompt is enough to trigger RGBA output. You can also extract a subject from an existing image as a transparent asset.

Lower API Price, Faster Output

On ByteDance's Volcano Engine Ark platform, Seedream 5.5 bills input and output images, with prompt text free. A 2K square edit costs 0.28 CNY, which ByteDance says is 60% cheaper than Seedream 5.0 Pro, with generation almost 40% faster.

Built for Production Work

ByteDance positions Seedream 5.5 for e-commerce marketing, ad design, film and game assets, storyboards and knowledge visuals, where edits must be exact and assets must be reused across scenes.

How to Write Prompts for Seedream 5.5

Say the Task First, Then the Style

Open with what to generate or what to change, and name the format: a poster, an infographic, a product hero shot, a character sheet or a magazine page. Add style words only after that.

Give On-Image Text Word for Word

Put every word that should appear in quotes, and say where it goes, how big it is and what color and weight it uses. Seedream follows exact text far better than vague requests like adding a catchy title.

Describe Structure, Not Just Mood

Position, hierarchy, composition and how blocks relate matter more than adjectives like premium or atmospheric. For example: a 3:4 cover with the top third blank for the title and a close-up of a hand holding the product below.

For Edits, Name What Stays

Point to the exact area, give the change, and list what must not move: change the jacket in the left figure to red leather, keep the face, pose, background, lighting and text layout the same.
