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 practical edit-model matchup across demanding briefs for layout, legible text, exact counts, and image-specific atmosphere. The results turn on whether precise instruction-following or a standout portrait matters more.
Krea 3 Edit takes the saved task sample decisively: it won **7 of 8 tasks**, with no ties, and scored **63.5** against Bytedance Seedream V4.5 Edit’s **50.3**. Its advantage was most consistent on briefs where the image had to obey explicit constraints rather than simply look appealing. Krea was stronger on the marsh relic arrangement, the three-line text treatment, the isometric bedroom, and the restricted duotone palette. It also made the seven terns’ interactions easier to read and rendered exactly seven fully visible cups in a clear row. Across those tasks, Seedream’s recurring weakness was letting composition or styling compromise the requested structure—cropped objects, awkward text, or colors outside the brief. Seedream’s win came on the storm-frayed osprey: its close, rain-soaked portrait better conveyed the bird’s anxious vigilance and post-squall atmosphere. The reflections-and-glass result went to Krea, though Seedream’s dramatic close-up had strengths of its own. Those exceptions don’t offset Krea’s broader run of more reliable constraint handling here. **Verdict: Krea 3 Edit is the clear pick on this task sample, especially for edits where placement, legibility, counting, or palette fidelity are non-negotiable. This assessment applies to the saved task sample, not every image-editing use case.**
Precise Marsh Relics Layout
A crisp natural-history style illustration of a marsh research table scene at golden hour with exact spatial relationships: a brass field compass is on top of a closed teal specimen notebook; a striped snail shell is to the left of the compass; a cattail seed head is behind the notebook; a glass vial half-filled with pond water is to the right of the notebook; a small frog figurine is between the shell and the notebook; and a dragonfly wing lies in front of the compass, not touching it. Everything arranged clearly on weathered cedar planks with soft side light and shallow depth of field, 16:9.
OpenAI: GPT-6 Luna: Model B more clearly satisfies the requested layout, with the compass on the closed notebook, the surrounding relics in their specified positions, and the dragonfly wing separated from the compass. Model A has attractive golden-hour lighting, but the open compass, cropped shell, and prominent full dragonfly make the arrangement less precise. (Second judge pass, order swapped — scores are the average of both: Model B follows the requested spatial relationships especially clearly, including the se | Anthropic: Claude Fable 5.1: Model B nails nearly every spatial constraint—f…
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 presents all three requested lines clearly, correctly spelled, centered, and legible on a deep navy background. Model A has oversized, overlapping and cropped text, with the schedule and location not cleanly rendered as the requested stacked lines. (Second judge pass, order swapped — scores are the average of both: Model B presents all three requested lines correctly spelled, crisp, centered, and clearly legible on a deep navy background.

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 presents a coherent isometric bedroom with the bed, window-side desk, centered round rug, and floor lamp all clearly visible. Model A includes the requested furnishings but uses a mostly frontal perspective and crops the rug and room, weakening the layout and composition. (Second judge pass, order swapped — scores are the average of both: Model B closely matches the requested isometric layout, with the bed on the left, centered round rug, desk beneath the back-wall window, and lamp in th | Anthropic: Claude Fable 5.1: Model B delivers a genuine isometric room with…
Alder Fen Duotone Palette
A watercolor illustration of a quiet fen at dawn with one red-crowned crane stepping through reeds and mirror-still water, rendered using only the named palette 'Alder Fen Duotone': moss green, peat brown, fog gray, and ivory, with absolutely no other hues anywhere in the image—not in reflections, shadows, highlights, sky, or the bird. Clean paper texture, delicate brush blooms, restrained tonal variation within those four colors only, balanced wide composition, 16:9.
OpenAI: GPT-6 Luna: Model B better respects the strict four-color palette and presents a quiet, balanced fen with a crane stepping through reeds and reflected in still water. Model A has a striking watercolor atmosphere, but its vivid red crown and peach-orange dawn tones directly violate the palette restriction, and the oversized, edge-cropped bird disrupts the composition. (Second judge pass, order swapped — scores are the average of both: Model B better honors the strict four-color palette and gives the crane an | Anthropic: Claude Fable 5.1: Model A breaks the central constraint with a br…
Storm-Frayed Osprey
A hyper-detailed wildlife portrait of a single osprey perched on a salt-bleached channel marker just after a squall, feathers plastered by rain and eyes wide with unmistakable anxious vigilance, beak slightly parted as if catching its breath; the emotion must read instantly as tense fear rather than aggression. Cinematic natural realism, telephoto compression, cold slate sky and distant marsh blurred into soft bokeh, low stormbreak light raking across the face and wet plumage, 16:9.
OpenAI: GPT-6 Luna: Model A more fully captures the rain-soaked, anxious portrait, with wide eyes, a slightly open beak, stormy light, and a salt-bleached marker. Model B has a clear full-body osprey, but the bird reads more merely alert, and the scene lacks the prompt’s wet, post-squall atmosphere. (Second judge pass, order swapped — scores are the average of both: Model A much more clearly captures the rain-soaked, anxiously vigilant osprey on a weathered marker, with cinematic storm light and a soft marsh backgr | Anthropic: Claude Fable 5.1: Model A delivers a true close-up portrait with…
Seven Terns at Brineglass Jetty
A lively watercolor illustration of seven roseate terns interacting on and around a crumbling black basalt jetty in a tidal lagoon: two adults exchanging a tiny silver sand eel beak-to-beak on the central post, one juvenile crouched below begging upward, one tern landing with wings flared at the far left, one lifting off from the water at the far right with droplets trailing, and two more birds standing together on a lower rock facing each other. The full group must read as one coherent, well-balanced scene with clear spacing, believable eyelines, and unified late-afternoon sea light under a pale apricot sky, 16:9.
OpenAI: GPT-6 Luna: Model B clearly presents all seven terns in the specified interactions, with balanced spacing and a readable jetty-and-lagoon setting. Model A has a lovely watercolor palette, but its oversized post and severely cropped birds make the group and several actions difficult to read. (Second judge pass, order swapped — scores are the average of both: Model B clearly presents all seven terns in the requested interactions, with balanced spacing, readable eyelines, and a unified lagoon setting.

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 presents exactly seven distinct cups in a clean straight row, with every cup fully visible and countable. Model A includes espresso, but the cups are oversized and cropped at the image edge, weakening the exact-count composition.

Reflections & glass
A photorealistic close-up of a chrome teapot on a polished dark marble counter next to a glass of water; the window and a red apple on the counter must be correctly reflected in BOTH the chrome and the water's surface, dramatic side light, 16:9.
OpenAI: GPT-6 Luna: Model A more strongly delivers the close-up, dramatic lighting, and prominent window and apple reflections across the chrome and water, though the apple’s placement is ambiguous. Model B shows the apple clearly and has a balanced composition, but its reflection in the water is less evident and the framing is less close.
