Head to head: Bytedance Seedream V4.5 Edit vs Google: Nano Banana Pro (Gemini 3 Pro Image)
Bytedance Seedream V4.5 Edit vs Google: Nano Banana Pro (Gemini 3 Pro Image)
By Ryan Merket · Published
Eight image-editing tasks put these models through tightly specified scenes, layouts, palettes, text, and object counts. The comparison rewards not just visual polish, but whether each image obeys the brief.
This matchup comes down to reliable instruction-following under visual constraints. Google’s Nano Banana Pro leads the aggregate score, 61.5 to Seedream V4.5 Edit’s 54.8, and wins five tasks to Seedream’s two, with one tie. The statistical verdict puts Google’s win at limited confidence: clear, but not a sweep. Google’s strongest results came where precision was hard to fake. It produced exactly seven countable espresso cups, arranged the potting-bench objects more faithfully, and delivered a cleaner restricted-palette campsite. Its moss-watering image made the fine spray legible, while its text poster kept the requested wording crisp—though it broke the title across two lines rather than the requested three-line layout. Seedream had the better answer to the midnight citrus poster and the no-plants reading-nook brief. In the latter, Google’s visible vegetation through the window broke an explicit constraint. The greenhouse aisle was a tie: both had strengths in perspective and composition, without a decisive overall edge. That split captures the difference: Seedream can make the more atmospheric image, but Google more often gets the specified details right. **Verdict: Nano Banana Pro wins on consistency and constraint-following, with a clear statistical edge—not an across-the-board advantage in image quality.**
Midnight citrus poster
A clean vector illustration of a nocturnal rooftop gardening scene featuring a single potted calamondin citrus tree with glossy leaves and seven glowing orange fruits, in a sleek editorial poster style with crisp shapes, limited palette of deep indigo, teal, and tangerine, subtle geometric shadows, tiny string lights draped on the railing, and a calm slightly dreamy mood under moonlit night air; balanced composition with generous negative space, 16:9.
OpenAI: GPT-6 Luna: Model B more clearly delivers the crisp, poster-like nocturnal rooftop scene, with the whole potted tree, moon, railing lights, and a restrained indigo-teal-orange palette. Model A is atmospheric and polished, but its oversized, partly cropped tree and busier rendering make the editorial composition less clean; Model B’s artwork also sits in an unusually narrow central panel with excessive side margins. (Second judge pass, order swapped — scores are the average of both: Model B captures the cris | Anthropic: Claude Fable 5.1: Model A delivers a genuine 16:9 editorial vecto…
Negation
A cozy reading nook with an armchair, a stack of books, and a mug of tea by a window — with absolutely NO plants, NO lamps, and NO artwork or picture frames anywhere in the frame. Warm afternoon light, 16:9.
OpenAI: GPT-6 Luna: Model A includes the requested nook elements and warm afternoon light while keeping the frame free of plants, lamps, and artwork. Model B is more fully composed, but visible vegetation through the window violates the explicit no-plants constraint. (Second judge pass, order swapped — scores are the average of both: Model B presents a clear, balanced reading nook with all requested items and warm afternoon light, while avoiding plants, lamps, and artwork. Model A also follows the constraints and h | Anthropic: Claude Fable 5.1: Model A satisfies every constraint cleanly — ar…
Macro moss watering
A true macro close-up photograph of a brass mister nozzle releasing tiny droplets onto a cushion of emerald bun moss beside the rim of a weathered terracotta pot, shot at very shallow depth of field with a 100mm macro lens look, razor-sharp focus only on the front edge of the nozzle and a few suspended droplets, creamy circular bokeh in the background, soft early-morning greenhouse light, highly detailed textures, cinematic 16:9 framing.
OpenAI: GPT-6 Luna: Model B more clearly shows the mister spraying droplets toward the moss, with the terracotta rim, shallow focus, and creamy greenhouse bokeh all strongly represented. Model A has beautiful macro detail and lighting, but its nozzle dominates the frame and the droplets read more as drips than a fine spray. (Second judge pass, order swapped — scores are the average of both: Model B more clearly shows the mister spraying suspended droplets directly onto emerald moss in a weathered terracotta pot, wi | Anthropic: Claude Fable 5.1: Model A has beautiful razor-sharp brass texture…
Restricted palette
A flat-vector illustration of a mountain campsite at dusk using ONLY four colors — cream, burnt orange, teal, and charcoal — with no gradients and no stray off-palette colors, balanced composition, 16:9.
OpenAI: GPT-6 Luna: Model B follows the four-color, flat-vector dusk brief closely and presents a clear, balanced campsite scene. Model A uses the right subject and palette, but its gradient-like sky and oversized, cropped foreground elements make the composition less faithful and polished. (Second judge pass, order swapped — scores are the average of both: Model B presents a complete, balanced flat-vector campsite scene and keeps to the requested four-color palette. Model A uses a similar palette but has visible g | Anthropic: Claude Fable 5.1: Model A is polished but breaks the core constra…
Greenhouse aisle perspective
An interior view down a long narrow greenhouse aisle in precise one-point perspective, with the vanishing point centered at the far doorway; identical wooden benches run along both sides, each holding progressively smaller rows of plants as they recede: closest on the right is a giant monstera in a 40 cm clay pot, opposite it on the left a medium lemon cypress half its height, farther down several smaller herbs and seed trays diminishing consistently with distance; overhead roof beams and floor tiles align cleanly to the same vanishing point, late-afternoon sun slants through glass panes, and all proportions must feel architecturally correct and unwarped, 16:9.
OpenAI: GPT-6 Luna: Model B presents a clearer, more balanced one-point greenhouse aisle, with the specified foreground monstera and lemon cypress and rows of plants receding toward the centered doorway. Model A has attractive late-afternoon light, but its oversized, cropped foreground plants and sparse benches make the scene feel less balanced and less consistently scaled. (Second judge pass, order swapped — scores are the average of both: Model B more clearly presents the balanced, centered aisle with orderly ben | Anthropic: Claude Fable 5.1: Model A delivers a cleaner one-point perspectiv…
Legible multi-line text
A minimalist event poster with three lines of crisp, correctly-spelled text stacked and centered: 'NIGHT MARKET' large on top, 'Fridays · 6–11pm' in the middle, 'Riverside Pier 4' at the bottom, on a deep navy background, clean sans-serif, subtle grain.
OpenAI: GPT-6 Luna: Model B renders the requested wording crisply and legibly with a polished navy poster look, though it splits the title across two lines instead of keeping the text to three lines total. Model A also breaks the title and has oversized, awkwardly spaced typography that weakens the composition. (Second judge pass, order swapped — scores are the average of both: Model B presents all requested wording clearly on a deep navy, subtly textured background in a balanced, minimalist layout, though it split | Anthropic: Claude Fable 5.1: Both render all three lines correctly spelled o…
Exact potting bench layout
A straight-on studio photograph of a cedar potting bench arranged with precise spatial relationships: a tall ribbed cobalt-blue watering can on the far left; a striped ceramic pot immediately to the right of the watering can; a packet labeled 'Kestrel Dahlia 204' lying flat in front of the striped pot; a small brass trowel placed between the striped pot and a square tray of seedlings; the seedling tray behind the trowel; a clear glass spray bottle on top of a closed moss-green gardening book; the book to the right of the seedling tray; and a pair of pruning snips resting behind the book, all evenly lit with soft studio light and composed so every item is fully visible.
OpenAI: GPT-6 Luna: Model B follows the requested left-to-right arrangement more closely, with the spray bottle on the book and all items fully visible; Model A has strong detail and readable packet text, but several objects are cropped and the spray bottle is not on the book. Model B’s packet label is too small to verify, though its overall composition is cleaner and more faithful. (Second judge pass, order swapped — scores are the average of both: Model B follows the requested left-to-right arrangement closely, k | Anthropic: Claude Fable 5.1: Model B reproduces nearly every spatial relatio…
Exact counting
A clean overhead flat lay on white marble of EXACTLY seven identical espresso cups arranged in a single straight row, each clearly separate and individually countable, even soft lighting, 16:9.
OpenAI: GPT-6 Luna: Model B shows exactly seven clearly separated cups in a straight overhead row on white marble, while Model A has more than seven and places the row awkwardly near the bottom edge. Model B is also more balanced and easy to count, though the espresso appearance varies between cups. (Second judge pass, order swapped — scores are the average of both: Model B shows exactly seven clearly separated, identical cups in a straight overhead row on white marble. Model A has more than seven cups, with cups c | Anthropic: Claude Fable 5.1: Model A shows nine espresso cups instead of the…
