Head to head: Seedream 5.5 Edit vs Krea 2 Large
Seedream 5.5 Edit vs Krea 2 Large
By Ryan Merket · Published
A close image-model matchup across typography, composition, anatomy, and color tasks. The comparison turns on how consistently each model follows the brief—not just on producing polished images.
Seedream 5.5 Edit takes the saved task sample, 5 wins to Krea 2 Large’s 3, with no ties. Its **aggregate score is 60.0**, against **57.1** for Krea. The editorial assessment is a **Slight edge (not statistical)**—a narrow result, not a decisive separation. Seedream’s clearest advantage was brief adherence on text and layout: it preserved requested wording, line structure, and hierarchy in both typography tasks, and more clearly organized the bedroom scene. It also won the hands-and-anatomy and library-perspective tasks, though the bracelet scene still had some ambiguity in the hands. Krea had its strongest results in the camera-and-lens, color-palette, and spatial-relationships tasks. Its gadget still life stayed closer to the requested cyan–magenta–violet palette, and its object arrangement was clean; in the lunar-bay task, though, Seedream better captured the requested setting and lighting. The camera-and-lens result went to Krea despite Seedream’s strengths in presenting the keycap and OLED, underscoring how close some of these calls were. **Final call: Seedream 5.5 Edit, by a slight edge on this saved task sample.** Its advantage came from more consistent execution of specific text, framing, and scene instructions, while Krea delivered meaningful wins in color and object-focused compositions. This assessment applies only to the saved task sample.
Legible text & typography
A minimalist startup expo poster mounted on a brushed aluminum wall for a fictional robotics company, in crisp Swiss modern graphic design with strong hierarchy and generous negative space, evenly lit and perfectly front-facing so all text is easy to read. The poster must clearly and correctly say exactly: "QUILLBYTE ROBOTICS" on the top line, "OPEN LAB 7" beneath it, and "09 OCT 2031" on the bottom line. Use bold sans-serif typography, black text on a warm cream poster, with a small geometric circuit icon and no other words.
OpenAI: GPT-6 Luna: Model A presents all three phrases exactly in the requested order and line structure, with clear hierarchy, generous negative space, and a suitable circuit icon. Model B keeps the wording legible but wraps the company name and event title across multiple lines, weakening adherence to the requested layout. (Second judge pass, order swapped — scores are the average of both: Model A presents all three phrases correctly in the requested hierarchy, with the company name kept on one top line and a cle | Anthropic: Claude Fable 5.1: Model A renders all three lines exactly, cleanl…
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 A more clearly places the bed, centered rug, desk beneath the back-wall window, and lamp in the front-right area, with polished, coherent isometric composition. Model B follows the requested flat-vector style more closely, but the furniture overlaps the rug and the overall layout feels less clear. (Second judge pass, order swapped — scores are the average of both: Model A places all requested furnishings clearly and has a cohesive, polished isometric composition, though its rendering is mo | Anthropic: Claude Fable 5.1: Model A delivers a polished, consistent isometr…
Hands & anatomy
A natural candid photo of a person tying a friendship bracelet, both hands clearly visible with anatomically correct fingers and a plausible grip on the threads, soft daylight, shallow depth of field, 16:9.
OpenAI: GPT-6 Luna: Model A more clearly shows the person actively tying threads with soft daylight and shallow depth of field, though the overlapping hands make the hand arrangement slightly ambiguous. Model B is polished, but depicts trimming a mostly finished bracelet and does not match the requested 16:9 framing. (Second judge pass, order swapped — scores are the average of both: Model B shows a bracelet and two fairly natural hands, but the person is cutting loose threads with scissors rather than tying the br | Anthropic: Claude Fable 5.1: Model A delivers the requested 16:9 candid scen…
Camera & lens framing
A macro close-up photograph of the exposed edge of a custom mechanical keyboard PCB, showing a single seafoam keycap corner, gold switch pins, a tiny OLED status screen, and one glowing amber solder joint in razor-sharp focus, with dramatic shallow depth of field and creamy bokeh falling off across the circuit traces. Shot as if with a 100mm macro lens at very close distance, cinematic side lighting, ultra-detailed textures, dark workshop background.
OpenAI: GPT-6 Luna: Model A more closely matches the cinematic macro brief, with a seafoam keycap, readable OLED, glowing amber joint, and appealing shallow-focus falloff. Model B includes PCB details and gold pins, but the screen is illegible and the lighting and framing feel less consistent with the prompt. (Second judge pass, order swapped — scores are the average of both: Model A more clearly presents the seafoam keycap, OLED, exposed circuitry, and glowing amber solder point in a polished macro composition wit | Anthropic: Claude Fable 5.1: Model B captures the brief far more literally—a…
Perspective & scale
A photorealistic one-point-perspective shot down a long empty library aisle, shelves receding to a single vanishing point, books getting consistently smaller with distance and nothing warped or wrongly sized, warm overhead light, 16:9.
OpenAI: GPT-6 Luna: Model A better matches the requested 16:9 photorealistic library aisle, with clear one-point perspective, consistently receding shelves and books, and warm lighting. Model B has a strong vanishing point too, but its square framing and prominent wall at the left reduce adherence and compositional balance. (Second judge pass, order swapped — scores are the average of both: Model B has a particularly clear centered vanishing point, but its square format misses the requested widescreen framing. Mode | Anthropic: Claude Fable 5.1: Model A delivers a true 16:9 photorealistic ais…
Color-palette accuracy
An elegant product still life of three experimental gadgets on a glass shelf — a foldable phone, a smart ring, and a pocket projector — rendered in a strict vaporwave triad palette only: electric cyan, hot magenta, and deep violet, with black and white allowed solely for line accents and specular highlights. No other hues anywhere in the image. Glossy reflective surfaces, soft studio gradients, symmetrical composition, 16:9, high-end advertising style.
OpenAI: GPT-6 Luna: Model B presents all three requested gadgets clearly on a glass shelf and stays closer to the cyan–magenta–violet palette, though its blue gradients stray slightly from the strict triad. Model A is visually polished but adds a busy city, large planet, and text that distract from the product still life and introduce more color variation. (Second judge pass, order swapped — scores are the average of both: Model B more directly matches the requested product still life and strict cyan-magenta-violet | Anthropic: Claude Fable 5.1: Model B stays within the cyan/magenta/violet tr…
Spatial relationships
A clean blueprint-style technical illustration of a retro-futurist electronics workbench in a moonbase repair bay, 16:9, lit by cool overhead task lights: place a translucent teal handheld game console exactly in the center; a copper drone propeller must be directly above it; a matte black soldering iron must be directly below it; a tiny silver hex key must be to the left of the console; a yellow memory card must be to the right; a coiled violet USB-C cable must be behind the console; a red diagnostic puck must be in front of it; and a white ceramic fuse must sit precisely between the hex key and the console. Crisp linework, measured spacing, no extra objects.
OpenAI: GPT-6 Luna: Model A closely follows the requested object placements while also establishing a convincing, cool-lit lunar repair bay in a wide blueprint-like technical illustration. Model B arranges the objects cleanly and clearly, but misses the requested setting, lighting, and 16:9 format; Model A’s main drawback is the extra background equipment and clutter. (Second judge pass, order swapped — scores are the average of both: Model B places the requested objects in the specified centered, above/below, and | Anthropic: Claude Fable 5.1: Model B places every object in the correct relat…
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 A renders all three lines crisply with the requested wording, capitalization, and punctuation, in a balanced minimalist layout. Model B has strong contrast and a centered arrangement, but the middle line changes the requested case and punctuation, and its very condensed typography feels less clean. (Second judge pass, order swapped — scores are the average of both: Model A renders all three requested lines with the correct wording, capitalization, and punctuation in a clean centered layout | Anthropic: Claude Fable 5.1: Model A renders all three lines exactly as spec…
