Head to head: FLUX 2 vs Krea 3 Edit
FLUX 2 vs Krea 3 Edit
By Ryan Merket · Published
Eight image-editing challenges put FLUX 2 and Krea 3 Edit through glass, text, macro detail, composition, and instruction-following tests. The results show two different strengths—and no decisive separation.
The scorecard is a dead heat in practice: FLUX 2 leads on four tasks and Krea 3 Edit on four, while the aggregate scores are close at 59.5 to 63.8. That small numerical gap doesn’t translate into a reliable overall advantage; confidence that either model is genuinely better is just 50%. FLUX 2 looks strongest when the brief depends on tactile detail and close observation. It produced the more convincing glass teapot and citrus macro, and better captured the watchmaker bench’s task-lamp mood and small workshop details. Its weakness is consistency: in the breakfast scene, it included a plant despite an explicit instruction not to, and its composition left an awkward blank area. Krea 3 Edit was more dependable on scene organization and spatial relationships. Its apple sat correctly on the counter, its library had stronger scale and perspective, and it handled the forbidden-object instruction cleanly. But it fell short on the teapot’s requested details and the extreme macro framing, where FLUX was more precise. The text-poster result is less clear-cut than the task label suggests: both models rendered the wording correctly, while the judges’ comments split over whether FLUX’s rendering or Krea’s more spacious, restrained layout better served the prompt. That ambiguity fits the wider comparison: neither model owns the full set of tasks. **Final call: a tie. FLUX 2 and Krea 3 Edit are effectively even here; the task you care about matters more than the small aggregate-score difference.**
Glass Teapot Refractions
A luminous realistic still life of a clear borosilicate glass teapot half-filled with pale jasmine tea on a polished cherrywood tray, beside two striped sugar cubes and a small tin labeled "Morrow Fen Tea No. 8," with the curved glass correctly reflecting the window frame, refracting the submerged tea leaves and the tray’s wood grain through the water, and casting delicate caustic highlights; calm late-morning natural light, balanced composition, 16:9.
OpenAI: GPT-6 Luna: Model A more fully matches the prompt, with striped sugar cubes, a clearly labeled tin, convincing glass refractions, and delicate caustic highlights. Model B has a pleasing, spacious composition, but the teapot’s form and the sugar cubes are less faithful to the requested details. (Second judge pass, order swapped — scores are the average of both: Model A presents a more convincing, luminous glass teapot with clear window reflections, delicate caustics, and a balanced still-life arrangement.

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 B more clearly places the apple on the counter and gives the scene stronger window reflections in the chrome and water, with dramatic side lighting and a polished dark-marble setting. Model A has an appealing close-up, but the apple sits on the rear ledge and the reflections in the water are less legible. (Second judge pass, order swapped — scores are the average of both: Model B places the red apple on the counter and shows it along with the window reflected in the chrome, with strong sid | Anthropic: Claude Fable 5.1: Model B clearly renders the window, the red app…
Macro Citrus Drop
A macro close-up food still life photographed with a 100mm lens, showing the cut edge of a blood orange on a matte ceramic plate as a single bead of juice trembles from one pulp segment, with extreme shallow depth of field, creamy bokeh, and the rind pores, translucent membranes, and tiny sugar crystals in pin-sharp focus; elegant editorial photography style, side-lit with warm afternoon light, subject placed off-center for refined framing.
OpenAI: GPT-6 Luna: Model A more convincingly delivers the extreme macro, creamy shallow focus, warm side light, and a distinct trembling juice bead, with rind and pulp textures sharply rendered. Model B has an elegant plate setting, but the framing is less macro and the conspicuous pale clump at the center distracts from the citrus detail. (Second judge pass, order swapped — scores are the average of both: Model A more fully delivers the requested extreme macro, with a distinct trembling juice bead, crisp rind por | Anthropic: Claude Fable 5.1: Model A delivers a true macro with the juice be…
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 correctly and clearly, but the bold type and tighter line spacing make the layout feel more compressed. Model B keeps the text crisp and centered while giving the lines more breathing room, with an elegant sans-serif treatment and subtle grain that better suits the poster prompt. (Second judge pass, order swapped — scores are the average of both: Model B better captures the requested subtle grain and refined minimalist poster feel while keeping all three lines cri | Anthropic: Claude Fable 5.1: Both render all three lines correctly spelled a…
Watchmaker Texture Bench
An ultra-detailed photorealistic tabletop scene of a watchmaker’s bench, featuring an opened mechanical pocket watch branded "Meridian & Vale," tiny blued screws, a cracked walnut-handled screwdriver, curled shavings of brass, and a square of dark indigo wool felt with clearly visible fiber weave and lint, every brushed metal surface, engraving, thread, and wood grain rendered razor-sharp without smudging; cool task-lamp lighting against a dim workshop background, tight three-quarter composition, 16:9.
OpenAI: GPT-6 Luna: Model A better captures the requested cool task-lamp lighting and tight three-quarter workshop scene, with visible felt lint, brass shavings, blue screws, and a cracked wooden screwdriver. Model B is sharply detailed, but its more overhead composition and lack of a visible task lamp weaken adherence; neither image clearly renders the requested brand name.

No Spoon Breakfast Nook
A cozy morning still life in a sunlit breakfast nook, painted in crisp contemporary realism, showing a chipped teal cereal bowl filled with blackberries and oat clusters, a squat glass bottle of saffron-colored milk, a folded newspaper with the masthead "North Quay Ledger," and a brass alarm clock reading 7:12 on a checkered linen tablecloth, with absolutely no spoon or any other utensil anywhere in the scene; soft low-angle window light, quiet domestic mood, careful composition with empty negative space on the right, 16:9.
OpenAI: GPT-6 Luna: Model B has the more coherent still-life composition, cleaner rendering of “North Quay Ledger,” and useful empty space on the right, though its clock does not read 7:12 and it lacks a visible window. Model A includes the window and appears closer to the requested clock time, but its large blank white area feels disconnected from the scene and its masthead is less legible. (Second judge pass, order swapped — scores are the average of both: Model B includes the requested objects, a clearly legible | Anthropic: Claude Fable 5.1: Model A has a severe rendering failure with rou…
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: Both images deliver a centered, empty library aisle with clear one-point perspective and warm lighting. Model B is more detailed and photorealistic, with convincing scale recession and a polished composition, while Model A is darker and softer. (Second judge pass, order swapped — scores are the average of both: Model B more fully matches the warm, photorealistic library prompt, with a clear centered vanishing point and convincing scale recession. Model A has strong one-point composition, but its | Anthropic: Claude Fable 5.1: Both deliver a clean centered one-point perspec…
Negation
A cozy reading nook with an armchair, a stack of books, and a mug of tea by a window — with absolutely NO plants, NO lamps, and NO artwork or picture frames anywhere in the frame. Warm afternoon light, 16:9.
OpenAI: GPT-6 Luna: Model A has inviting warm light and the requested reading-nook elements, but prominently includes a plant despite the explicit prohibition. Model B includes the chair, books, tea, and window without forbidden decor, with a balanced composition and warm afternoon light. (Second judge pass, order swapped — scores are the average of both: Model B includes the requested chair, books, tea, window, and warm afternoon light without any forbidden objects.
