RuntimeWire Head-to-Head: Head to head: FLUX 2 vs Krea 3 Edit
RuntimeWire Head-to-Head matchup

A comparison of two image models across eight demanding prompts, from ukiyo-e styling and biomechanical devotional scenes to exact counts, reflections and spatial composition. The results turn on whether broad prompt fidelity can outweigh occasional misses on tightly specified details.

Krea 3 Edit takes this matchup on breadth, not on flawless execution. It won seven of eight tasks, with FLUX 2 taking none, and finished ahead 66.5 to 55.0. The statistical verdict is decisive, with a tentative lean; this is not a narrow aggregate win disguised by one standout image. Krea’s edge shows up across very different briefs: it better captured the flat indigo-and-cream ukiyo-e look, made the biomechanical shrine more clearly devotional, and presented all five color-coded relics without the merchant’s hands intruding. It also produced stronger reflection-focused and one-point-perspective scenes. On the room-layout prompt, the judges’ individual assessments diverged, but the averaged task verdict still went to Krea. The win doesn’t mean Krea nailed every constraint. Neither model hit the exact nine-moth count—FLUX showed seven, Krea ten—and the reflection images both missed the requested window-and-apple reflections in the water. Krea’s shrine also introduced cool ambient light where candlelight alone was requested. The hangar-canal scene was the sole tie: Krea had the stronger centered vanishing point, while FLUX made the shuttle and supporting figures more legible. **Final call: Krea 3 Edit wins decisively.** FLUX 2 had moments of stronger atmosphere and clarity, but across these eight tasks Krea followed the briefs more reliably and delivered the stronger overall set.

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.

Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model B more clearly depicts a fishing boat riding the cresting wave and better captures the flat indigo-and-cream planes, bold outlines, and stylized foam of ukiyo-e. Model A has a warmer dawn sky, but its detailed rigging and more dimensional rendering feel less faithful to the requested print tradition. (Second judge pass, order swapped — scores are the average of both: Model B more closely matches the requested muted indigo-and-cream ukiyo-e look, with a small fishing boat, bold flat planes, | Anthropic: Claude Fable 5.1: Model B delivers a convincingly authentic ukiyo…

Candlelit biomech shrine

Inside a forgotten sci-fi shrine beneath the moon of Orisel, a biomechanical saint-statue kneels before a ring of black candles, rendered as dark baroque cinematic concept art; the entire scene is lit only by candlelight, with warm trembling amber illumination, deep velvety shadows, faint smoke, reflective bronze and bone-white surfaces catching tiny highlights, and a solemn devotional mood, symmetrical composition facing the altar, 16:9.

Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model B more clearly depicts a kneeling, prayerful biomechanical saint in a symmetrical shrine, with strong bronze-and-bone detail and a ring of black candles. Model A better sustains the warm candlelit darkness and smoke, while Model B’s cool blue ambient illumination partly conflicts with the candlelight-only requirement.

Color-bound relic market

A richly detailed fantasy market stall on the sky-bridge of the floating city Veyra, painted in a crisp storybook-concept-art style, showing five distinct objects arranged clearly on dark velvet so their attributes are easy to verify: a cobalt blue glass astrolabe, a matte crimson leather spellbook, a pale jade ceramic mask, a polished brass compass, and a violet silk banner folded over the counter; each object must keep its own exact color and material with no color bleeding or swapped surfaces, medium-close composition with the merchant’s gloved hands out of frame, soft overcast daylight, 16:9.

FLUX 2: FLUX 2
Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model B presents all five relics clearly, keeps their colors distinct, and better evokes a richly detailed sky-bridge market while keeping the merchant’s hands out of frame. Model A is also polished, but the visible gloved hands directly contradict the prompt and its setting feels less specific. (Second judge pass, order swapped — scores are the average of both: Model B clearly presents all five distinct color-and-material objects on dark velvet, with the merchant’s hands out of frame and a rich | Anthropic: Claude Fable 5.1: Both renders include all five objects with corr…

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.

FLUX 2: FLUX 2
Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model B makes the window and red apple legible in the chrome reflections and presents a clear close-up with dramatic light, while Model A has weaker, less identifiable reflections. Neither image clearly shows both the window and apple reflected in the water’s surface, but Model B comes closer overall to the reflection-focused prompt. (Second judge pass, order swapped — scores are the average of both: Model B has a stronger close-up composition and a clear window reflection in the chrome, with re | Anthropic: Claude Fable 5.1: Model B more directly fulfills the core reflect…

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.

FLUX 2: FLUX 2
Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model A follows the requested isometric layout closely, with all four furnishings clearly placed as specified and a cohesive flat-vector look. Model B includes the same key items, but its more frontal perspective is less consistent with the requested isometric style and makes the room feel less spatially coherent. (Second judge pass, order swapped — scores are the average of both: Model B places all four requested furnishings more precisely, especially the desk directly beneath the back-wall win | Anthropic: Claude Fable 5.1: Model B places all four items correctly (bed on…

Nine moths of Nacre Fen

A luminous fantasy natural-history illustration of an alchemist standing knee-deep in Nacre Fen at dusk, holding up a lantern while EXACTLY nine distinct glasswing moths circle above the water—each moth fully visible, separate, and individually countable, with no extras hidden in the reeds or background; bioluminescent lilies, mist, and mirrored reflections enrich the scene, painterly realism, centered composition, 16:9.

FLUX 2: FLUX 2
Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model A has a beautiful, richly detailed fen and recognizable glasswing moths, but shows only seven rather than nine. Model B is closer to the requested count with ten visible moths, and its centered figure and mirrored reflections make a strong scene, though the extra moth still breaks the exact-count constraint. (Second judge pass, order swapped — scores are the average of both: Model B has a strong centered, atmospheric fen scene and comes closer to the requested moth count, though it appears | Anthropic: Claude Fable 5.1: Model A shows only seven colorful butterfly-lik…

Vanishing point hangar canal

A wide hard-surface sci-fi illustration of the maintenance canal inside Dock Spine 47, viewed from walkway level with a strong single vanishing point dead center: in the foreground a small repair drone and a waist-high toolbox, in the midground two human technicians and a compact shuttle, and in the far distance a colossal carrier ship framed by receding gantries; all relative sizes must be believable and the perspective lines of rails, pipes, floor markings, and ceiling trusses must align consistently with no warping, cool industrial lighting, ultra-clean composition, 16:9.

FLUX 2: FLUX 2
Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model B delivers the more emphatic centered vanishing point, with exceptionally consistent receding lines and a clearly framed carrier; its Dock Spine 47 signage also reinforces the setting. Model A has a more clearly recognizable shuttle and appealing cinematic lighting, but Model B’s overall composition follows the prompt more closely. (Second judge pass, order swapped — scores are the average of both: Model A more clearly presents the compact shuttle, two technicians, foreground repair drone | Anthropic: Claude Fable 5.1: Model B delivers a sharper dead-center single va…

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.

FLUX 2: FLUX 2
Krea 3 Edit: Krea 3 Edit

OpenAI: GPT-6 Luna: Model B offers a cleaner, more convincing one-point perspective, with crisp shelves and books that recede consistently toward a single vanishing point. Model A has the requested warm, empty aisle, but its strong foreground blur and darker, less defined shelves make the perspective and scale less clear. (Second judge pass, order swapped — scores are the average of both: Model B delivers a crisp, convincing one-point-perspective aisle with consistently receding shelves and warm overhead lighting. | Anthropic: Claude Fable 5.1: Model B delivers a crisp one-point perspective w…
