Head to head: FLUX 2 vs Krea 3 Edit
FLUX 2 vs Krea 3 Edit
By Ryan Merket · Published
FLUX 2 and Krea 3 Edit trade strengths across tightly specified image tasks, from exact object details to cinematic scenes. This head-to-head weighs literal prompt fidelity against composition and atmosphere.
The saved aggregate scores are **62.4 for FLUX 2** and **63.3 for Krea 3 Edit**. The task results favor FLUX 2 by count—four wins to three, with one tie—but the saved overall result is a tie, and the aggregate scores are close. Neither the score difference nor the task tally settles the matchup on this sample. FLUX 2’s clearest wins come on exact counting, macro geartrain detail, and the midnight rescue convoy. It made the espresso visible in seven distinct cups, delivered a tighter geartrain close-up, and included more of the convoy brief’s specific rescue elements. Those are meaningful advantages when a prompt depends on countable objects and precise details. Krea 3 Edit stood out in the tram depot, conductor portrait, and reflections tasks. Its depot signage and layout were more legible, its conductor scene better conveyed sunrise and motion, and its teapot image made the reflections clearer. The attribute-binding task was a tie: both models handled the requested object arrangement well, with different strengths around the small blue cylinder. **Final call: Too close to call (not statistical).** FLUX 2 has the edge in task wins, while Krea 3 Edit has the slightly higher aggregate score; neither warrants declaring an overall winner. This assessment applies only to the saved task sample.
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 shows exactly seven distinct espresso-filled cups in a clean, straight row on white marble, while Model B also has seven cups but they appear empty and more tightly crowded. Model A has the clearer, more polished presentation overall. (Second judge pass, order swapped — scores are the average of both: Model B and Model A both show exactly seven cups in a straight overhead row, but Model A makes the espresso contents clear and keeps the cups distinctly countable. Model B has softer lighti | Anthropic: Claude Fable 5.1: Both Model A and Model B render exactly seven c…
car-free tram depot
A rain-slicked 1930s brick tram depot at blue hour, three teal-and-cream vintage trams resting on parallel tracks under warm sodium lamps, puddles reflecting the overhead wires and glowing route numbers, two mechanics in dark oilskin coats checking a switch box beside stacks of spare rails, cinematic realism with crisp wet textures and deep perspective, wide 16:9 composition, and absolutely no cars, buses, bicycles, or motorcycles anywhere in the scene.
OpenAI: GPT-6 Luna: Model B has clearer route numbers, a more legible depot layout, and stronger deep perspective while matching the wet, lamp-lit scene; Model A has especially vivid reflections but its route signage is garbled. Both show three vintage trams, mechanics at a switch box, spare rails, and no prohibited vehicles. (Second judge pass, order swapped — scores are the average of both: Model B more completely matches the requested scene, with clearly readable route numbers, three vintage trams, mechanics at | Anthropic: Claude Fable 5.1: Model B delivers more authentically 1930s trams…
quiet pride conductor
A close three-quarter portrait of a commuter rail conductor standing on the platform of tiny Brindleford Junction just after sunrise, one hand resting on a worn ticket punch, face lit by soft golden side light as a departing diesel multiple unit blurs behind him, his expression showing quiet pride after a flawless final run before retirement—subtle smile, moist eyes, relaxed brow, steady posture—painted in contemporary realist editorial illustration with natural skin texture and believable facial anatomy.
OpenAI: GPT-6 Luna: Model B more strongly captures the warm sunrise, departing train motion, and quiet, emotional pride, with a polished editorial-realism style. Model A makes the ticket punch clearer and includes a strong station sign, but its background feels less dynamic and the lighting less evocative. (Second judge pass, order swapped — scores are the average of both: Model B more closely captures the close three-quarter portrait, golden sunrise light, hand on the worn punch, and departing train in motion; Mod | Anthropic: Claude Fable 5.1: Model A nails the literal checklist (handheld t…
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 shows a more natural, anatomically convincing grip while clearly depicting the bracelet being fastened, with soft daylight and a pleasing composition. Model A is a strong close-up of the weaving process, but its fingers look less distinct and the grip is less convincing. (Second judge pass, order swapped — scores are the average of both: Model A more clearly shows both hands plausibly gripping and working the bracelet threads, with natural-looking fingers and a focused shallow-depth-of-f | Anthropic: Claude Fable 5.1: Model A delivers a close, well-lit shot with so…
Attribute binding
A photorealistic tabletop scene: a matte green cube to the LEFT of a glossy red sphere, a small blue cylinder BEHIND both, and a single yellow rubber duck sitting ON TOP of the cube. Colors must stay on the correct objects. Soft studio light, 16:9.
OpenAI: GPT-6 Luna: Model A more closely matches the requested scale, especially with a small blue cylinder behind the other objects, while preserving the specified colors and duck-on-cube placement. Model B is polished and well composed, but its blue cylinder is much taller and less clearly small. (Second judge pass, order swapped — scores are the average of both: Model A better matches the requested small blue cylinder behind the foreground objects, while preserving the cube-left, sphere-right arrangement and duc | Anthropic: Claude Fable 5.1: Model A satisfies every constraint — green cube…
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 shows the window and red apple reflected in the chrome teapot, with a stronger close-up composition and more convincing dramatic light. Model A includes the requested objects, but neither image makes the apple’s reflection on the water surface especially clear. (Second judge pass, order swapped — scores are the average of both: Model B more clearly shows the window and red apple reflected across the chrome teapot, while keeping the apple, water glass, and dramatic side light | Anthropic: Claude Fable 5.1: Model B places the apple on the counter as spec…
macro geartrain detail
Studio product photography of a cutaway marine chronometer gearbox from the research vessel Isolde-9, arranged on matte black acrylic with tiny engraved brass gears, knurled steel shafts, braided copper wiring, flecked enamel calibration dials, and a strip of salt-stained canvas gasket, hyper-detailed macro realism with every tooth, weave, scratch, and machining mark rendered razor-sharp, controlled cross-polarized lighting, dark seamless background.
OpenAI: GPT-6 Luna: Model A better captures the requested razor-sharp macro product photograph, with prominent engraved-looking gears, knurled shafts, braided copper wiring, canvas gasket, and dark acrylic setting. Model B includes a readable “ISOLDE-9” label and calibration dials, but its wider, less cohesive view feels less like a macro geartrain detail. (Second judge pass, order swapped — scores are the average of both: Model B includes the Isolde-9 marking and many specified materials, but its wider framing mak | Anthropic: Claude Fable 5.1: Model A delivers a tighter macro view with dram…
midnight rescue convoy
A coherent multi-subject scene of a midnight mountain rescue convoy on the Serac Ladder Pass: a red tracked snow ambulance idling near a collapsed guardrail, a yellow cable-reel service truck angled behind it, three rescue workers passing a folded stretcher to two climbers wrapped in silver thermal blankets, a drone operator kneeling beside open equipment cases, drifting snow illuminated by alternating amber beacons and a cold moonlit ridge, dynamic cinematic realism, balanced triangular composition, 16:9.
OpenAI: GPT-6 Luna: Model A follows more of the requested details, especially the collapsed guardrail, red tracked ambulance, two blanket-wrapped climbers, and three rescue workers, while its moonlit mountain setting creates a strong cinematic triangular composition. Model B is also visually compelling, but its guardrail is intact and the rescue group appears to include three wrapped people rather than two. (Second judge pass, order swapped — scores are the average of both: Model A more clearly depicts the tracked | Anthropic: Claude Fable 5.1: Model A delivers nearly every element with a cle…
