Three things Seedream 4.0 does best, according to Reddit

Detail that holds up at 4K

Detail that holds up at 4K

"Seedream generally gives the best results at 4k," one r/fal reply advised. This espresso machine shows every gear, spring and copper pipe through clear plastic.

  • Name the material: crafted completely from transparent hard plastic
  • Ask for the insides by part: gears, gauges, springs, copper tubing
  • Clear the stage: pure white background, object centred, even light

"I would never have guessed this was AI," one r/aiArt reader wrote under a Seedream 4.0 post. This sunlit portrait is one of four frames fofrAI posted, each 4096 pixels wide.

  • Set the light and its direction: warm late sun from the left
  • Give the lens: shallow depth of field, foliage blurred behind
  • Ask for real skin: visible pores and small imperfections

An r/aiArt commenter put the draw plainly: it can "eliminate thousands of dollars and weeks of time spent on professional Photoshoots". This ramen came from a one-line food prompt.

  • Start with the dish and every topping: egg, seaweed, green onion
  • Add the genre: cinematic food photography
  • Close with light and depth: soft overhead light, shallow depth of field

Memory rooms inside a crystal cube

Memory rooms inside a crystal cube

@umesh_ai

The cube and its tiny rooms first, then lens, aperture, focus point and the colours of the bokeh.

Photorealistic macro of a cracked crystal cube suspended above an antique desk. Inside the cube: micro-rooms flicker—childhood toys, rain on windows, a hallway turning into waves. 90mm macro, f/2.8, razor focus on fracture line; refracted bokeh blooms in aurora mint, lilac haze, pale amber. Dust motes sparkle like constellations. A silver key lies beneath, reflected multiple times within the cube, skewing scale. Subtle anamorphic flare. Story: each refracted facet misremembers the key in a new shape, proving memory is a prism, not a mirror.

A silhouette in twilight fog

A silhouette in twilight fog

@rovvmut_

One subject, two light sources, blue fog against a golden flare, finished with film grain.

A solitary man in dramatic silhouette stands amidst tall, wild grass under a moody twilight sky. His blonde messy fade hair catches faint streaks of warm sunset light as his eyes remain closed in calm reflection. Thick fog swirls around him, illuminated by deep blue ambient light and a golden flare from the setting sun. The scene has an ethereal, high-contrast aesthetic with cinematic grain, evoking introspection and dreamlike serenity.

Dish, genre, light, texture: four short blocks split by bars.

Fried egg and bacon in a perfect cube

Fried egg and bacon in a perfect cube

@AleRVG

Every texture described, from glossy fat to wrinkled egg white, then the shape it must obey.

A cube covered in runny fried egg whites with streaks of yolk and strips of crispy bacon, resting on a plate, with a background of white square tiles. The egg whites are semi-transparent and slightly wrinkled, the yolk golden and reflective. The bacon is reddish-brown, glossy with rendered fat, curling along the curve of the sphere. The cube has a layered, uneven surface that looks freshly cooked, illuminated by bright daylight that enhances the contrast between textures. The composition is ap perfect shape of a cube

Seedream 4.0 vs 4.5, 5.0 Lite, 5.0 Pro and Nano Banana 2

The models people weigh it against, and where Seedream 4.0 comes out ahead on Kavel.

Seedream 4.0 vs Seedream 4.5

Seedream 4.0 takes your photos as references and lets you pick 1K, 2K or 4K; 4.5 here writes from text only, with no size choice. Seedream 4.0 costs four fifths of 4.5.

See Seedream 4.5

Seedream 4.0 vs Seedream 5.0 Lite

The same 20 credits, and both edit your photos. Seedream 4.0 adds a 1K, 2K or 4K choice you pick in the generator.

See Seedream 5.0 Lite

Seedream 4.0 vs Seedream 5.0 Pro

Seedream 4.0 costs two thirds of Pro at Basic, and it reworks the photos you upload, which Pro here does not.

See Seedream 5.0 Pro

Seedream 4.0 vs Nano Banana 2

At 1K the price is the same. At 4K, Seedream 4.0 costs less than half of what Nano Banana 2 does, which is why r/singularity readers kept pointing at its resolution.

FAQ

Seedream 4.0 FAQ

The questions people ask most in the threads.

You can start free: log in and Kavel adds free credits, no card, for Kavel's own image engine and Nano Banana 2 Lite. Seedream 4.0 runs on any paid plan or credit pack, cost shown before you generate.

20 credits per image at 1K, 2K or 4K, and editing a photo costs the same. Failed runs are refunded automatically, unless the prompt broke the content policy.

Yes. Choose 4K in the generator and Kavel sends that preset with your prompt, still 20 credits. Pick 4K for prints, wallpapers and anything you will crop; 1K is fine for drafts.

Right here in the browser: pick Seedream 4.0, type or upload, and generate. The weights are private, so there is no local version; nothing to install and no API key needed.

Generate the face once, upload it as a reference with each new prompt, and write that the face stays identical. Add a full-body photo when build and outfit must match too.

Upload your photo, add a second image showing the pose you want, and describe the change in plain words. Calling the second image the pose reference is the tip r/singularity users passed around.

Start with the object and the word macro, describe the tiny scene inside it, then add lens, focus and the colours of the light. The crystal-cube prompt card on this page is built exactly that way.

On Kavel, pick Seedream 4.0 when you want to upload photos or choose 4K, and when price matters: it costs four fifths of 4.5. Seedream 4.5 here takes text only.

Make your first Seedream 4.0 image

Stop leaving the image in your head unmade: paste a proven prompt or upload your photo, pick 4K, and make it for 20 credits, less than half the price of Nano Banana 2 at the same size. Runs that error out on our side are refunded.
