Create a graffiti collage poster about collaborative street printing, using lime green, aubergine purple and mint over a gray-white photocopied paper texture. Oversized “PRINT PLAY!” lettering overlaps diagonally.

A candid horizontal street photograph of a long-haired woman in a burgundy top and light brown jacket looking down at her phone. Strong wind sweeps her hair across her sunglasses and face. The entire frame tilts about 25 degrees clockwise, with consistent perspective across the figure, buildings, lamppost and pavement. Natural clothing folds, hurried framing and asymmetric cropping create an unposed everyday moment.

Create an illustrated infographic poster titled “FROM SEED TO SALAD” on warm-white paper with a handmade print texture. One continuous path snakes across three tiers, linking six numbered stages in order: SOW, SPROUT, GROW, TEND, HARVEST and SHARE. Five correctly directed arrows connect the sequence. Pair miniature gardening scenes and English descriptions with each stage, keeping the reading order clear, lettering legible and colors soft yet varied.

A horizontal ultra-wide-angle photograph of a curious gray-brown donkey peering through a vertical gap in a weathered wooden fence. Its broad muzzle nearly touches the lens, while its eyes and long ears recede in exaggerated close-up perspective. Focus on the muzzle’s fine hair, whiskers and skin texture, with softly blurred fence boards, blue sky and grass beyond. Natural daylight creates a playful candid moment.

A fantasy picture-book illustration with delicate gouache textures, set in a cloud-sea glider workshop. A bear mechanic steadies the mast, a red panda pilot pulls the sail rope from inside the boat, and an otter assistant approaches in the foreground carrying a wooden securing pin. A low, upward-looking view and gently tilted perspective emphasize the bow, triangular sail and tall timber roof. Cream, deep teal and honey-colored wood create a bright, warm scene of teamwork.

Seedream 5.5 multi-turn editing: change one thing, keep the rest

Each Seedream 5.5 edit starts from the previous result. Areas you did not touch stay pixel for pixel, with no color shift, so a painting, a product or a face survives many rounds.

The paper, the vase and the first branch never move; new elements arrive in the same brush style. ByteDance pushed Seedream 5.5 to 100 successive edits of one portrait, still swapping rings and eyeglass frames precisely at the end.

Seedream 5.5 transparent PNG: native RGBA output

Seedream 5.5 can return an image with a real alpha channel. Switch the backdrop and the same lettering, soft shadow included, sits cleanly on every color.

Prompt

Create “Seedream 5.5” inspired by the reference texture and style. Use rounded, bold sans-serif letters wrapped in alternating royal-blue and lake-blue yarn, with visible fibers, fuzz and side shadows. Use a 16:9 landscape format with a transparent background outside the lettering.

Full and partial transparency

Seedream 5.5 writes alpha for clear areas and for semi-transparent ones such as shadows, glass, smoke or fur, with edges drawn by the model rather than cut out later.

From text or a reference

Describe an asset, or point the model at a reference image to borrow its texture, as the yarn lettering above does.

Ready to reuse

Transparent stickers, characters and titles drop into posters, slides and mockups with no background removal step.

What is Seedream 5.5?

Seedream 5.5 is ByteDance Seed's next-generation image creation model, announced on November 9, 2026. It follows Seedream 5.0 Pro, creates images from a text prompt or reference images, and edits images you already have.

Seedream 5.5 brings three upgrades. Multi-turn editing is steadier: unedited regions are preserved at the pixel level with no color shift, across up to 100 rounds. Seedream 5.5 generates native RGBA images with full or partial transparency. And photos look more real, with natural light, materials and skin, while dense small text in English and Chinese comes out more accurately.

ByteDance says a Pro version of the Seedream 5.5 series will follow, without a date. Seedream 5.5 is already live in Dreamina by CapCut and on third-party API platforms.

Seedream 5.5 realism and text rendering

Seedream 5.5 makes photos believable and posters usable without a retouch pass.

Photos that feel unposed

Seedream 5.5 prompt tips

Seedream 5.5 follows plain, concrete language best, the way ByteDance writes its own examples.

  • Lead with the subject

    Open with what the picture is about, then add setting, lens, light and style.

  • Quote every word that must appear

    Put headlines and labels in quotes and say where they sit. Seedream 5.5 text is far more reliable, but proofread prices, dates and names.

  • Ask for transparency in words

    For a cut-out, describe the subject alone and ask for a transparent background outside it.

  • Edit one thing per round

    Name the change and what must stay: "add a red seal, keep the vase unchanged". Small steps are where Seedream 5.5 multi-turn editing shines.

  • Reuse your references

    For a recurring character or product, attach the same reference images to every prompt.
