Head to head: Bytedance Seedream V4.5 Edit vs Krea 3 Edit
Bytedance Seedream V4.5 Edit vs Krea 3 Edit
By Ryan Merket · Published
A head-to-head across eight image-editing tasks, from exact object counts and palette control to art-style fidelity, emotion, and fine detail. The comparison tests both models on precise constraints and more interpretive visual direction.
Krea 3 Edit took four task wins to Bytedance Seedream V4.5 Edit’s three, with one tie. Krea was stronger on exact counting, the restricted-palette campsite, ukiyo-e fidelity, and the marsh still life: its outputs kept objects legible and constraints clear. Seedream stood out on the Pahari miniature, the relieved wildlife rescuer, and the dew-covered moth macro, where it better delivered the requested style, emotion, or detail. Spatial layout was scored a tie. The aggregate scores favor Krea—**61.5** to Seedream’s **55.3**—but the saved result for this matchup is a tie. The task wins are split, and the models’ strengths fall in different places; the aggregate edge alone doesn’t justify declaring an overall winner. **Final call: Too close to call (not statistical). This assessment applies to the saved task sample.**
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 clearly shows exactly seven separate, identical cups in a straight row on white marble. Model A has attractive espresso detail, but the cups are heavily cropped and the exact count is unclear. (Second judge pass, order swapped — scores are the average of both: Model B clearly shows exactly seven identical, separate cups in a straight overhead row on white marble. Model A is a polished close-up, but the cups are heavily cropped and crowded, so they are not individually countable and the e | Anthropic: Claude Fable 5.1: Model A shows only six cups, with the first and…
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 presents a clear, balanced campsite scene in clean flat-vector shapes and stays close to the four-color palette. Model A has an appealing palette, but the oversized, cropped foreground and textured sunset conflict with the requested balanced, gradient-free illustration. (Second judge pass, order swapped — scores are the average of both: Model B clearly presents a balanced, flat-vector mountain campsite in the requested four-color palette, while Model A is heavily cropped and introduces g | Anthropic: Claude Fable 5.1: Model A is the more polished and richly compose…
Art-style fidelity — Pahari miniature hornbills
In the style of an 18th-century Pahari miniature painting, depict two Malabar pied hornbills perched on a twisted wild fig branch above a jade-green forest ravine, one passing a small crimson berry to the other; use the characteristic fine opaque gouache look, delicate almond-shaped leaves, lyrical contour lines, flattened yet elegant spatial layering, ornate patterned border bands, and jewel-toned mineral pigments with gold accents, viewed in a calm side-on composition under soft monsoon dawn light, 16:9.
OpenAI: GPT-6 Luna: Model A more fully captures the prompt with prominent hornbills exchanging a clear crimson berry, a lush ravine, jewel-toned gouache-like color, and an elaborate gold-accented border. Model B includes the key subjects and framing but makes the birds much smaller and the scene darker and less distinctly Pahari in its flattened, lyrical miniature style. (Second judge pass, order swapped — scores are the average of both: Model A more clearly depicts the berry being passed between recognizable hornb | Anthropic: Claude Fable 5.1: Model A delivers nearly every requested element…
Emotion — relieved wildlife rescuer
A young wildlife rescuer kneeling in wet dune grass at sunrise, cradling a just-freed common seal pup in a towel, her face showing unmistakable relieved joy after hours of effort: trembling smile, damp lashes, lifted cheeks, slightly open mouth, and exhausted tears catching the light; wind-flattened hair, salt spray on her jacket, the pup looking calm against her chest, cinematic close-medium composition with a softly blurred grey sea behind, natural golden side light, 16:9.
OpenAI: GPT-6 Luna: Model A more clearly conveys relieved joy through the rescuer’s trembling smile and visible tears, while strongly matching the towel-wrapped pup, wet dune grass, sea, and golden sunrise. Model B includes the key scene elements, but its rescuer reads as more distressed than joyful and the wider framing makes the emotion less immediate. (Second judge pass, order swapped — scores are the average of both: Model A makes the requested relieved joy especially unmistakable, with visible tears, windblown | Anthropic: Claude Fable 5.1: Model A delivers a convincing relieved joy—lift…
Named art style
A ukiyo-e woodblock print of a fishing boat riding a large cresting wave at dawn, faithful to the flat color planes, bold outlines, and stylized foam of the tradition, muted indigo and cream palette.
OpenAI: GPT-6 Luna: Model B more convincingly captures ukiyo-e through its bold contours, flat indigo-and-cream planes, and stylized foam, while showing a fishing crew riding a dramatic crest at dawn. Model A has appealing waves and warm dawn light, but its painterly gradients and sailboat feel less faithful to the requested woodblock tradition. (Second judge pass, order swapped — scores are the average of both: Model B closely matches the ukiyo-e tradition with bold outlines, flat indigo-and-cream planes, stylized | Anthropic: Claude Fable 5.1: Model B is far more faithful to ukiyo-e convent…
Fine detail — dew-laden moth study
An extreme close-up macro portrait of a rosy maple moth resting on a lichen-speckled birch twig, every surface rendered with crisp micro-detail: powdery scales on the pink-and-cream wings, feathery antennae, tiny hooked leg hairs gripping bark fissures, translucent dew beads clinging to moss filaments, and sharply resolved birch texture with peeling paper-thin layers; cool predawn light with a dark forest bokeh background and razor-thin depth of field centered on the moth’s head and thorax.
OpenAI: GPT-6 Luna: Model A delivers the requested extreme macro with striking wing and antenna detail, visible dew, lichen, and layered birch bark against dark bokeh, though the moth’s face looks somewhat distorted. Model B is a cleaner, more conventionally composed portrait, but it feels less extreme and shows fewer of the requested micro-details. (Second judge pass, order swapped — scores are the average of both: Model A more fully delivers the extreme macro study, with strikingly resolved feathery antennae, dew | Anthropic: Claude Fable 5.1: Model A delivers the requested extreme macro fr…
Attribute binding — marsh still life
A meticulously arranged natural-history still life on a weathered driftwood table beside a reed-fringed marsh: a matte cobalt-blue ceramic pitcher, a translucent amber glass jar, a brushed copper field compass, a pale mint-green silk ribbon, a chalk-white seashell, and a black volcanic-stone bowl filled with three small tangerines; each object must keep its own exact color and material with no color swapping or bleeding, lit by clear late-afternoon sunlight from the left with crisp cast shadows, three-quarter view, 16:9.
OpenAI: GPT-6 Luna: Model B presents all six specified objects clearly in a well-organized still life, with the requested materials, colors, marsh setting, and crisp sunlight. Model A has attractive lighting and realism, but several objects are cut off by the frame, making the arrangement less complete and legible. (Second judge pass, order swapped — scores are the average of both: Model B presents the complete, carefully arranged still life with all six objects clearly visible, including exactly three tangerines, | Anthropic: Claude Fable 5.1: Model B renders every object with the correct co…
Spatial layout
A clean isometric illustration of a bedroom: a bed against the LEFT wall, a round rug centered on the floor, a desk under the WINDOW on the back wall, and a floor lamp in the FRONT-RIGHT corner. Flat-vector style, consistent perspective.
OpenAI: GPT-6 Luna: Model B clearly presents the full isometric room with the bed, centered round rug, desk beneath the back-wall window, and lamp in the front-right corner. Model A includes the requested furnishings but is tightly cropped, making the room layout harder to read and the rug and lamp partially cut off. (Second judge pass, order swapped — scores are the average of both: Model B clearly presents all four requested elements in the specified positions, with a clean, consistent isometric layout. Model A i | Anthropic: Claude Fable 5.1: Model A places all four elements correctly—bed…
