Seedream 5 Pro vs Seedream 5 Lite for Image Generation
Seedream 5 Pro was the stronger pick across more of these fixed-prompt scenarios, particularly for product construction, typography, anatomy, composition, reference-heavy edits, and outpainting. Seedream 5 Lite came out ahead for coherent relighting and product preservation during a scene change, while several structured, counting, and text-editing tasks were ties.

Scenario by scenario
Both models ran the identical prompt under our fixed suite - the images are the published runs, shown exactly as generated.
Product material and lighting
Better here: Seedream 5 ProLeft more completely matches the requested perfume-bottle construction, half-fill level, subtle reflection, and coherent product lighting. Right is visually polished but lacks an evident perfume closure and has a less convincing reflection.
- Exactly one transparent rectangular perfume bottle is visible, with no text, logo, or extra objects: Left does better. Both show one transparent rectangular vessel without visible text, logos, or extra objects, but Left is clearly identifiable as a perfume bottle because its cap and spray mechanism are visible; Right resembles an open rectangular glass container.
- The bottle is visibly filled halfway with amber liquid: Left does better. Its amber liquid reaches roughly the midpoint of the main bottle body with a clearly defined level; Right is also near half-full, but the liquid occupies slightly less than half of the visible inner chamber.
- The glass refraction and the reflection on the wet black stone are physically coherent: Left does better. Its thick glass edges, internal distortions, and amber reflection align convincingly with the bottle. Right has a strong outlined reflection that does not clearly reproduce the amber-filled portion, plus another bright reflected fragment lower in the frame.
- Upper-left lighting produces consistent highlights and a plausible contact shadow: Left does better. Highlights are strongest along the top and left-facing glass surfaces, while the bottle has a grounded shadow directly beneath it. Right also has plausible directional highlights and a contact shadow, but the very bright reflection and edge highlights are less restrained.
Prompt & settings used
Prompt
A premium product photograph of exactly one transparent rectangular perfume bottle, half filled with amber liquid, standing upright on wet black stone. Light comes from the upper left, creating coherent refraction, a contact shadow, and one subtle reflection. No text, logo, plants, or extra objects.
Multilingual typography
Better here: Seedream 5 ProLeft follows the requested four-line poster structure exactly, while Right turns the first requested line into two lines. Both handle the wording, colors, and legibility well otherwise.
- Exactly four centered text lines and no additional text: Left does better. It shows exactly four centered lines: "MOONLIGHT MARKET", "月光市集", "18 OCT", and "RIVER HALL". Right splits the heading into "MOONLIGHT" and "MARKET", producing five visible lines.
- Exact wording and order: Left does better. Its four lines read exactly "MOONLIGHT MARKET", "月光市集", "18 OCT", and "RIVER HALL" in that order. Right renders the same words and characters in order, but "MOONLIGHT MARKET" is split across two lines.
- Required text colors: Tie. Both render "月光市集" in red and all English text, including "MOONLIGHT MARKET", "18 OCT", and "RIVER HALL", in black.
- Legibility, spacing, and alignment: Left does better. Its text is clear, centered, and arranged as four aligned lines; Right is also legible and centered, but splitting "MOONLIGHT MARKET" disrupts the requested four-line arrangement and creates a less consistent vertical layout.
Prompt & settings used
Prompt
Design a clean cream-colored vertical event poster. Show exactly four centered text lines and no other text: "MOONLIGHT MARKET", "月光市集", "18 OCT", and "RIVER HALL". Render "月光市集" in red and all other lines in black.
Human anatomy and contact
Better here: Seedream 5 ProLeft more consistently satisfies the anatomy and contact requirements. Right is photorealistic, but its overlapping, clay-covered fingers make the hand structure and finger count substantially less clear.
- Exactly two fully visible hands are present, with no extra hands or people: Left does better. It clearly shows only one potter and two hands, with each hand readable as a complete hand; Right also shows only two hands and no other person, but the tight overlap makes their boundaries less clear.
- Each hand has exactly five distinct, naturally formed fingers: Left does better. Five fingers can be visually accounted for on both hands despite some contact occlusion. In Right, overlapping fingers near the bowl make the thumb and finger count on each hand difficult to distinguish confidently.
- The fingers, joints, and contact with the clay are anatomically plausible: Left does better. Its joints, nail placement, finger lengths, and opposing inside/outside grip look natural. Right has less convincing anatomy around the clay-covered central fingers, where the overlap looks crowded and ambiguous.
- The clay bowl, spinning wheel, and shaping action are clearly recognizable: Left does better. The full bowl profile, wheel head, and inside/outside shaping grip are all clearly visible. Right also shows the bowl and wheel, but the tighter crop and overlapping hands obscure more of the shaping action.
Prompt & settings used
Prompt
A photorealistic close-up of an adult potter shaping a clay bowl on a spinning wheel. Both hands are fully visible, each with five natural fingers touching the clay. No other people or hands. Soft window light.
Counting and attribute binding
Depends on the taskBoth images meet all four criteria without a meaningful visible difference in prompt adherence.
- Object count and placement: tie; both images visibly show exactly three red cubes in a row on the left, exactly two blue spheres on the right, and one yellow mug centered behind the foreground objects.
- Colors, shapes, and materials: tie; both images clearly bind red to wood-grained cubes, blue to transparent reflective glass spheres, and yellow to a smooth ceramic mug.
- Mug handle direction: tie; the handle is clearly visible on the right side of the mug in both images.
- No additional objects or text: tie; neither image contains any visible extra object or text.
Prompt & settings used
Prompt
On a matte gray table, exactly three red wooden cubes form a row on the left, exactly two blue glass spheres sit on the right, and one yellow ceramic mug stands centered behind them. The mug handle points right. No other objects or text.
Advertising composition
Better here: Seedream 5 ProLeft follows the requested composition more completely, especially by keeping the shoe fully visible and placing the headline closer beneath the reserved top space.
- Exactly one silver shoe and orange trail: Left does better. It shows one complete silver shoe in the lower-right, while the orange trail visibly starts at the bottom-left and curves upward. Right also has one silver shoe and an orange trail, but much of the shoe is cropped off by the right edge.
- Only visible text: Tie. Both images show only "RUN LIGHT" and "42 KM", with both phrases spelled correctly and no additional visible text.
- Top area and headline placement: Left does better. Its top area is visibly empty, and "RUN LIGHT" sits in the upper-left directly beneath that space. Right also leaves the top uncluttered, but "RUN LIGHT" is positioned substantially farther down.
- Element visibility and hierarchy: Left does better. The headline, badge, trail, and shoe are all fully visible and clearly separated. In Right, the shoe is heavily cut off at the right edge, so not all required elements are fully visible despite the otherwise clear hierarchy.
Prompt & settings used
Prompt
Create a vertical social ad for a fictional running shoe named AERO. Keep the top 15 percent empty. Directly below it, place the headline "RUN LIGHT" in the upper-left. Show exactly one silver shoe in the lower-right, an orange trail curving from the bottom-left, and a round badge reading "42 KM". No other shoes or text.
Structured UI graphic
Depends on the taskBoth images satisfy all four rubric criteria. The visible differences are stylistic and do not establish an overall rubric advantage.
- Title and columns: Tie. Both render the exact title "CHOOSE YOUR PLAN" and exactly three columns labeled "STARTER", "PRO", and "TEAM".
- Rows: Tie. Every column in both images contains exactly the three labels "PROJECTS", "STORAGE", and "SUPPORT", arranged in aligned rows.
- Buttons: Tie. Every column in both images has exactly one blue button labeled "SELECT".
- Alignment and extra content: Tie. Both show three evenly spaced columns with consistent internal alignment and no additional columns or text.
Prompt & settings used
Prompt
Create a clean horizontal pricing comparison graphic titled "CHOOSE YOUR PLAN". Use exactly three equal columns labeled "STARTER", "PRO", and "TEAM". Under each column, show exactly three aligned rows labeled "PROJECTS", "STORAGE", and "SUPPORT", followed by one blue button labeled "SELECT". White background, dark navy text, no additional columns or text.
Six-reference object binding and edit
Better here: Seedream 5 ProLeft follows the requested object set cleanly and presents the complete arrangement without edge crowding. Both appear successful on the replacements, but the left is the stronger result for framing and full object visibility.
- Mug and napkin replacement: tie. Both show a dark navy-blue mug and a folded green-and-white striped napkin in comparable tabletop positions; the exact reference appearance and base placement cannot be verified because the source references are not shown.
- Pear and notebook replacement: left does slightly better. Both show exactly one orange and a mustard-yellow hardcover notebook with no visible pear or blue notebook, but the left keeps both replacement objects fully and comfortably framed while the right notebook is crowded against the right edge.
- Lemon addition: left does better. Both show exactly two lemons to the right of the mug with no extra fruit, but the left displays both lemons fully within the frame, whereas the right places them close to the bottom edge.
- Base-scene preservation: left does better visibly. Its landscape framing keeps every object fully visible with balanced spacing, while the right uses a substantially taller composition and crowds objects against the right and bottom edges. Exact preservation of Reference 1's camera, wood grain, lighting, and shadows cannot be confirmed without seeing Reference 1.
Reference images
Prompt & settings used
Prompt
Use Reference 1 as the base tabletop scene. Replace the red mug with the exact dark navy-blue mug from Reference 2 in the same position and orientation. Replace the folded white towel with the exact green-and-white striped napkin from Reference 3 in the same folded area. Replace the green pear with exactly one orange from Reference 4 in the same position. Replace the blue notebook with the exact mustard-yellow hardcover notebook from Reference 5 in the same position. Add exactly the two lemons from Reference 6 to the right of the mug. Preserve the wooden table, camera, framing, wood grain, lighting, shadows, and all other spatial relationships from Reference 1. Do not copy the white product backgrounds from References 2–6, duplicate any asset, or add other objects.
In-image text replacement
Depends on the taskBoth outputs satisfy the visible text requirements equally well. The criteria requiring comparison with the original cannot be verified from these two outputs alone, so there is no defensible overall winner.
- Exact sign text: Tie. Both signs visibly read exactly "NIGHT OWL", with no visible remnants of earlier text.
- No additional or malformed characters: Tie. Both render only "NIGHT OWL" in clear, correctly formed uppercase letters.
- Original font character, spacing, and perspective: Cannot be fully assessed without the original image. Both use a similar clean uppercase sans-serif style with consistent spacing and lettering aligned plausibly to the sign perspective.
- Unchanged material, lighting, and scene: Cannot be assessed against the original image. Both show a dark green painted-wood sign with natural shadows, but the surrounding storefront framing differs substantially between the two outputs.
Reference images
Prompt & settings used
Prompt
Replace only the sign text with exactly "NIGHT OWL". Preserve the original font style, spacing, perspective, sign material, lighting, and everything else.
Multi-reference identity and garment transfer
Better here: Seedream 5 ProLEFT has a modest visible advantage in anatomical and garment-fit coherence, but exact identity and jacket-reference fidelity cannot be verified without the two source references.
- Identity, expression, hair, pose, body proportions, and framing: This cannot be conclusively assessed because Reference 1 is not shown. The outputs visibly differ in facial details and framing, with LEFT showing more of the lower torso, but there is no basis for determining which is closer to the reference.
- Jacket material, color, collar, buttons, pockets, and sleeve patch: This cannot be conclusively assessed against Reference 2 because it is not shown. Both depict a light-blue denim jacket with a cream shearling collar, metal buttons, flap chest pockets, and a red upper-sleeve patch; RIGHT renders the denim texture and pocket stitching more distinctly, while LEFT presents the overall construction more cleanly.
- Black suit replacement and exclusion of mannequin/product background: Tie. Both fully show the person in the denim jacket, with no visible black suit, ghost mannequin, or white product background.
- Hands, garment fit, occlusion, shadows, and lighting: LEFT does better. Its hands and overlapping fingers are more clearly separated, the cuffs meet the wrists cleanly, and the jacket sits naturally around the torso. RIGHT has muddier finger intersections at the center and a bulkier, less natural sleeve fit, though its scene lighting remains coherent.
Reference images
Prompt & settings used
Prompt
Use the portrait in Reference 1 for the person and the isolated jacket in Reference 2 for the garment. Dress the person from Reference 1 in the exact jacket shown in Reference 2. Preserve the person's identity, face, expression, skin, hair, hands, pose, body proportions, background, framing, and lighting from Reference 1. Preserve the jacket's material, color, collar, buttons, pockets, and sleeve patch from Reference 2. Do not copy the ghost mannequin or white product background.
Coherent scene relighting
Better here: Seedream 5 LiteRight more clearly establishes directional golden-hour sunlight from the left and carries that source through localized highlights and long, consistent shadows.
- Warm golden-hour light clearly enters from the left window: right does better; intense warm sunlight is visibly concentrated at the left window and projects across the room, while left also shows warm window light but with a less pronounced directional path.
- Highlights and shadow directions respond coherently to the new light source: right does better; the table, sofa, plant, and window frame cast consistent elongated shadows toward the right, with corresponding highlights on their left-facing surfaces. Left is broadly coherent but its shadow pattern is less consistently defined across the floor and furniture.
- The result is more than a uniform yellow color filter: right does better; it preserves darker neutral areas while adding localized sunlit patches, window-shaped projections, and object shadows. Left also goes beyond a uniform tint, but the warm cast is more evenly spread through the scene.
- No furniture or decor is moved, added, removed, or redesigned: this cannot be assessed reliably without the original source image; both outputs visibly contain the same general set of objects, but their preservation relative to the source is unknown.
Reference images
Prompt & settings used
Prompt
Change the lighting to warm golden-hour sunlight entering from the left window. Do not move, add, remove, or redesign any object. Update highlights and shadows coherently.
Cross-ratio outpainting
Better here: Seedream 5 ProLeft is the stronger result. It presents a natural wide outpainting and keeps the cabin centered, while Right fails the requested landscape framing and shifts the main subject to the right.
- 1. The final output is 16:9 with natural new content on both sides: Left does better because it is clearly a wide landscape with plausible beach, ocean, and sky continuing across both sides. Right is much closer to a tall or square canvas than 16:9.
- 2. The complete original image remains centered without cropping or stretching: Left does better because the cabin and surrounding composition are centered with substantial space on both sides. Right places the cabin noticeably right of center. Exact preservation cannot be confirmed without the source image.
- 3. The original cabin, shoreline, and internal composition remain unchanged: This cannot be conclusively assessed without seeing the original image. The two outputs visibly differ in cabin scale, placement, and details, but that alone does not establish which preserved the source more accurately.
- 4. Extensions have no visible seams, mirrored filler, or repeated objects: Tie. Both show continuous sky, ocean, waves, and sand without an obvious boundary, mirrored section, or duplicated object.
Reference images
Prompt & settings used
Prompt
Expand the canvas to a 16:9 landscape by naturally continuing the beach, ocean, and sky on both sides. Keep the complete original image centered without cropping, stretching, letterboxing, or modifying it.
Product preservation across scene change
Better here: Seedream 5 LiteRight more convincingly establishes the requested basketball-court setting and provides the stronger wet-surface reflection, while visible product details are comparable between the two outputs.
- Wet outdoor basketball court at dusk: Right does better. A basketball hoop is visibly present, the court is broadly wet and reflective, and the orange dusk sky clearly establishes the time and setting. Left shows a wet marked court, fence, and lit poles, but no visible hoop.
- Silhouette, sole geometry, stitching, materials, and camera angle consistency: This cannot be fully assessed without the original sneaker image. Between the outputs, both show nearly identical low-top silhouettes, white leather-like panels, stitching patterns, layered soles, and side-on camera angles; neither has a clear visible defect that decisively wins this criterion.
- Black geometric side mark: The original cannot be checked for exact preservation, but both outputs render a crisp, readable black angular mark with the same bent horizontal segment, rising diagonal, central junction, and descending diagonal. This criterion is a tie.
- Contact shadow, wet-surface reflection, and dusk lighting: Right does better. The sole has a continuous contact shadow, the large foreground reflection follows the sneaker's placement and silhouette, and the warm sky is reflected across the wet court. Left has credible contact and puddle reflections, but the sneaker reflection is less complete and visually fragmented.

Prompt
Place the sneaker on a wet outdoor basketball court at dusk. Preserve the exact sneaker shape, black geometric side mark, materials, stitching, sole geometry, and camera angle. Add physically coherent contact, reflections, and dusk lighting.
Cost & latency
Seedream 5 Pro starts at 25 credits, while Seedream 5 Lite starts at 20 credits, so Lite has the lower minimum generation cost. In this run, observed latency ranged from 38569 ms to 141015 ms for Pro and from 30002 ms to 89665 ms for Lite; these are small-sample observations, not benchmark figures.
