Head to head: Krea 3 Realtime vs Google: Nano Banana Pro (Gemini 3 Pro Image)
Krea 3 Realtime vs Google: Nano Banana Pro (Gemini 3 Pro Image)
By Ryan Merket · Published
Eight image-generation tasks put Krea 3 Realtime and Google’s Nano Banana Pro through scene-building, exact counting, anatomy, and style constraints. The comparison rewards not just attractive images, but how clearly each one follows the brief.
Google’s Nano Banana Pro takes this matchup, 65.3 to 58.6, winning seven of eight tasks. The statistical verdict puts that result at limited confidence: decisive, not a photo finish. Its edge is consistency across very different briefs, from rainy restaurant realism to constrained illustration. Nano Banana Pro’s strongest work is specific rather than merely polished. It made the open-kitchen viewpoint and rainy reflections more coherent, kept the bracelet-making action legible, and showed the baker’s braided dough, hands, and requested props more completely. It also handled the ukiyo-e fishing boat and the four-color campsite brief with greater clarity and constraint discipline. The counting results show the difference between meeting a requirement and presenting it well: both models produced exactly 11 ramune bottles and exactly seven cups, but Nano Banana Pro made the objects easier to distinguish and count. Krea’s one win was equally concrete: its tea kiosk kept straws out of the scene, while Nano Banana Pro added a conspicuous bundle that violated the prompt. Krea can deliver atmosphere, and its noodle-bar image had plenty of it, but across this set it more often let a requested action, object, or constraint become less clear. **Verdict: Nano Banana Pro is the stronger all-round image model here; Krea wins when the brief’s most important test is simply keeping straws out of frame.**
Rainy noodle bar realism
A photorealistic evening scene inside a narrow noodle bar during light rain, viewed from a corner booth toward the open kitchen: brushed steel stock pots, a worn walnut countertop, glazed ceramic bowls, folded linen napkins, a cook’s slightly dewy skin, and a dark green waxed canvas jacket hanging by the door, all rendered with physically believable reflections, subsurface skin tones, damp street glow through the window, soft tungsten pendants, accurate shadow falloff and material contrast, cinematic 16:9
OpenAI: GPT-6 Luna: Model B more clearly captures the requested view toward an open kitchen, with a strong counter-led composition and convincing rainy street reflections, warm pendants, and material contrast. Model A has excellent atmosphere and prominently includes the jacket and tableware, but its kitchen feels more separated and the overall scene is less cohesive. (Second judge pass, order swapped — scores are the average of both: Model B more fully captures the corner-booth viewpoint, with a compelling counter | Anthropic: Claude Fable 5.1: Model A checks more literal items (clearly gree…
Count 11 ramune bottles
A crisp studio still life in a clean contemporary advertising style: exactly 11 distinct Japanese ramune soda bottles arranged on two pale ash-wood shelves against a muted pistachio backdrop, every bottle fully visible and individually countable, with mixed glass colors and marble stoppers, tiny handwritten flavor tags, no extra bottles, no cropped items, soft frontal lighting with gentle shadows, straight-on composition, 16:9
OpenAI: GPT-6 Luna: Both Model A and Model B show exactly 11 fully visible bottles on two shelves, but Model B has clearer flavor tags, more varied glass colors, and a more polished, balanced arrangement. Model A follows the setup well, though its spacing is less even and its tags are harder to read. (Second judge pass, order swapped — scores are the average of both: Model B clearly shows exactly 11 distinct, fully visible ramune bottles across two shelves, with varied colors, marble stoppers, readable flavor tags, | Anthropic: Claude Fable 5.1: Both renders contain exactly 11 bottles, but Mo…
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 A and Model B both show exactly seven cups in a straight row, but Model B makes the cups more clearly separate and individually countable without adding saucers. Model B also has a cleaner, more consistent arrangement, while both images have attractive marble surfaces and soft lighting. (Second judge pass, order swapped — scores are the average of both: Model B shows exactly seven clearly separate, identical cups in a clean straight row without extra tableware. Model A also has seven cups, | Anthropic: Claude Fable 5.1: Both Model A and Model B render exactly seven i…
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 B more clearly shows a candid bracelet-making moment, with both hands visibly manipulating the colorful threads and a pleasing shallow-focus outdoor setting. Model A has a clean close-up, but the curled hands obscure the fingers and make the tying action less legible. (Second judge pass, order swapped — scores are the average of both: Model B better captures the candid, sunlit bracelet-making scene, with both hands clearly engaged in a plausible grip and pleasing shallow depth of field.

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 clearer, more balanced campsite scene and adheres more closely to the flat-vector style and four-color palette. Model A includes the key campsite elements but uses more tonal variation and has a less balanced foreground. (Second judge pass, order swapped — scores are the average of both: Model B more closely follows the strict four-color, no-gradient requirement while clearly depicting a dusk campsite in a balanced 16:9 scene.

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 A captures the muted indigo-and-cream palette and dramatic wave especially well, but the fishing boat is less clearly legible. Model B makes the boat and dawn unmistakable while maintaining bold outlines, flat color planes, and stylized foam in a polished ukiyo-e composition. (Second judge pass, order swapped — scores are the average of both: Model B clearly shows a fishing boat and crew riding beneath a dramatic cresting wave, with dawn light, bold outlines, stylized foam, and a faithful | Anthropic: Claude Fable 5.1: Model A nails the muted indigo-and-cream woodblo…
No straws tea kiosk
A vintage travel poster for the fictional seaside town of Brineharbor featuring a cheerful iced-tea kiosk under striped awnings, stacks of lemons, glass dispensers of hibiscus tea, handwritten menu boards, and sun-faded deck chairs overlooking the marina — but absolutely NO drinking straws anywhere in the scene, not on the counter, not in cups, not in signage; bold mid-century shapes, limited color palette, breezy afternoon light, 16:9
OpenAI: GPT-6 Luna: Model A captures the vintage seaside tea-kiosk scene and keeps the counter and cups free of straws. Model B is also polished and well composed, but the conspicuous bundle of straws on the counter directly violates the prompt’s strongest constraint. (Second judge pass, order swapped — scores are the average of both: Model B is a polished vintage poster with the requested marina, kiosk, lemons, and tea, but the cup of upright sticks on the counter reads as drinking straws, directly violating the k | Anthropic: Claude Fable 5.1: Model A fulfills every element—striped awnings,…
Anatomy baker hands
A candid editorial food photograph of a left-handed pastry chef in a cobalt-blue apron shaping braided saffron dough on a flour-dusted marble counter, shown from mid-thigh up with both hands fully visible in the foreground, all ten fingers clearly separated and anatomically correct, natural shoulder width and arm proportions, a copper mixing bowl, a jar of cardamom, and three pear tarts nearby; warm morning window light from the right, shallow depth of field, realistic skin texture and posture, 16:9
OpenAI: GPT-6 Luna: Model B more clearly shows the braided saffron dough, both hands with separated fingers, and the requested cardamom jar, copper bowl, and pear tarts; its bright window-lit composition also feels more like an editorial food photograph. Model A has attractive warm lighting, but the dough is mostly obscured and several requested details are missing or less clear.
