Seedream 4.5 Review: Uncensored 4K Images and Edits at $0.04

The gallery holds nine published examples from the Seedream 4.5 model page, six text-to-image and three edits, all made on 21 October 2026. Everything in it is clothed and publishable; our content-test images are not shown, and those results are described in words.

Wide and detailed. A woman in an emerald evening gown leans on a Manhattan rooftop rail at blue hour, city lights below and string lights behind her, at 6240 x 2656. That 21:9 frame at 4K is the big-canvas test.

Lettering. A 1970s film poster with its title and tagline, and a perfume advertisement with the name engraved in gold on the bottle, both spelled exactly as typed.

A group of people. Four friends around a Palm Springs pool in Kodachrome colour: four different faces, four different poses, nobody merged into a neighbour.

Dance and sport. A tango couple in a dim Buenos Aires hall with other dancers blurred behind them, and a boxer on the apron of a ring in hard side light.

Edits. From one portrait the model made a Mediterranean terrace scene in a white linen sundress with the face and hair kept, and a 1940s film-noir still. From a portrait and a gown photo it made the opera-staircase picture.

Write a short brief, not a keyword list. Start with the medium ("Gritty documentary photograph of…", "Luxury perfume advertisement."), then the people with an age and wardrobe, then the setting, one light source and a lens or film note. Put any text you need in double quotes and say where it sits. For edits, call each source by number, say what changes and what must stay. Keep every person an adult.

1. Text-to-image, lettering on a product. aspect_ratio 1:1, resolution 2k.

Luxury perfume advertisement. A faceted black glass bottle stands on wet black stone, a single drop running down the glass, one narrow beam of warm gold light from the left. Engraved on the bottle in gold: "NOIR VELOURS". Bottom centre, in thin gold sans-serif capitals: "EAU DE PARFUM". Studio product photography, deep shadows, crisp reflections.

2. Text-to-image, a documentary portrait. aspect_ratio 3:4, resolution 2k.

Gritty documentary photograph of a male boxer in his thirties sitting on the apron of an old boxing ring, sweat on his face and arms, hands wrapped in white tape, grey tank top, towel around his neck, staring past the camera. Hard window light from the left, dust in the air, peeling paint on the walls, one red glove hanging from the ropes as the only strong colour. Film grain, desaturated palette.

3. Edit, a face and a garment from two photos. Two sources in image_urls, the woman then the gown; aspect_ratio 3:4.

Dress the woman from Image 1 in the red satin gown from Image 2. Keep her face, freckles and long red hair exactly as in Image 1. Place her on a marble staircase in an opera house lobby at night, one hand on the brass rail, looking down at the camera, warm chandelier light, full-length shot.

4. Edit, a new place from one photo. One source; aspect_ratio 3:4.

Keep the face, hair and pose of the woman in Image 1. Move her to a sunlit Mediterranean terrace with whitewashed walls, blue shutters and pink bougainvillea, change her outfit to a white linen sundress, and light the scene with golden late-afternoon sun from the left.

Weak: a list of tags with no sentence structure, or "make her look better" with no source named. Strong: a full sentence per subject, the light source named once, and for edits a clear "keep" list.

SpicyAPI adds no content filter. On 21 October 2026 we ran 24 probes across both endpoints at the default 2K settings, with adult subjects only, covering five intensity levels from Mild to Maximum, and checked every image by eye. Nothing was refused and nothing errored: a request either came back as written or came back toned down. We publish the levels, not the test prompts.

Reading the table. Text-to-image delivered every level except Very strong, where both runs came back toned down. Edits delivered Mild, Moderate and Maximum and toned down Strong and Very strong. Most levels had one run per endpoint, so read this as a map of where the model's own limits sit, not a promise for every prompt. Quality at the edge is also uneven: one Very strong run came back with muddled anatomy.

What this means for you. Most requests render as written. If a result is softened, rewording or running again can change it, but the model, not SpicyAPI, decides how far it goes at the top end.

Adults only, in every prompt and every source photo. Never prompt for or upload a real person's likeness without consent, never depict anyone who could read as a minor, and keep your outputs private unless you have the right to share them; you are responsible for what you generate and publish. Generated media is kept for 14 days and then deleted.
