Head to head: FLUX 2 vs Ideogram V4.5 Edit
FLUX 2 vs Ideogram V4.5 Edit
By Ryan Merket · Published
Eight image-generation challenges put widescreen composition, precise scene details and text rendering under the microscope. The results turn on whether a model follows the brief—not simply whether it can make a polished image.
FLUX 2 takes this matchup decisively: it wins seven of eight tasks, with one tie, and leads 64.0 to 54.3. The judges assigned the result limited confidence. The pattern is clear: FLUX more reliably honored the requested framing and scene details, while Ideogram often produced polished images that drifted from the brief. That difference showed up repeatedly in composition. FLUX delivered the requested 16:9 frame for the perspective scene, storm-skate poster, finish-line moment and velodrome study; Ideogram’s square framing weakened each. It also captured the specified rainy underpass, midnight riverside lighting and numbered velodrome lane more faithfully. Ideogram had attractive polish—and stronger close-up product detail in the velodrome task—but those strengths didn’t make up for missing the requested setting or composition. FLUX also won the text challenge by rendering the exact wording in the requested three-line layout. Ideogram’s version was legible, but split the title across two lines and changed its casing and dash style. In the goalkeeper scene, FLUX showed the keeper adjusting a glove strap despite imperfect hand anatomy; Ideogram made the fingers clearer but missed the action, showing the strap held between bare hands. The one tie came in the spatial-layout task: FLUX placed the room elements more precisely, while Ideogram better matched the requested clean isometric style. That close call is the exception, not the story of the set. **Verdict: FLUX 2 is the stronger choice when prompt fidelity, framing and specific visual details matter most.**
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 framing while maintaining a clear, centered vanishing point and convincing scale recession. Model B is more polished and symmetrical, but its square format misses the specified aspect ratio. (Second judge pass, order swapped — scores are the average of both: Model B has a crisp, compelling central vanishing point and warm lighting, but its square framing misses the requested 16:9 format. Model A matches the widescreen format while keeping the empty aisle | Anthropic: Claude Fable 5.1: Model A delivers a clean 16:9 one-point perspec…
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 cleanly matches the requested layout, with the bed along the left wall, a centered round rug, a desk beneath the back-wall window, and a lamp in the front-right corner. Model B is polished but busier, and its rug is partly tucked beneath the bed rather than clearly centered on the open floor. (Second judge pass, order swapped — scores are the average of both: Model B more closely matches the requested clean flat-vector isometric style and clearly places the bed, centered rug, desk b | Anthropic: Claude Fable 5.1: Model A places every element exactly as specifi…
Storm skate poster
A stylized illustration of a lone street skateboarder carving through an empty underpass just after a summer cloudburst, head down and jacket flaring, with a mood of defiant calm; clean vector poster style with minimalist line art accents, limited palette of asphalt teal, rust orange, and cream, bold geometric shadows from overhead strip lights, dynamic diagonal composition, 16:9.


OpenAI: GPT-6 Luna: Model A more fully captures the prompt with a rain-streaked underpass, a flaring rust jacket, and a strong 16:9 diagonal poster composition. Model B has bold, polished vector styling, but its square format and lack of clear post-cloudburst details make it less faithful. (Second judge pass, order swapped — scores are the average of both: Model A more fully captures the rainy underpass, flaring jacket, wet pavement, and widescreen poster composition, while Model B has a clean vector look and stron | Anthropic: Claude Fable 5.1: Model A delivers the 16:9 format, rain streaks,…
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 closely follows the requested three-line centered layout and renders all text correctly and clearly on a deep navy, subtly grained background. Model B is bold and legible, but splits the title across two lines, changes the requested casing and dash style, and uses a much more pronounced texture. (Second judge pass, order swapped — scores are the average of both: Model A renders the exact requested wording in three centered lines on a deep navy background, with a clean minimalist treatmen | Anthropic: Claude Fable 5.1: Model A renders all three lines exactly as spec…
Relief at the finish
A rain-soaked ultramarathon runner in a midnight-blue singlet marked with the number 4821 stands just beyond a finish tape on a dim riverside course, clutching a crumpled silver heat sheet and laughing through tears with unmistakable exhausted relief, cheeks flushed, lower lip trembling, eyes wet and half-closed; cinematic sports photo realism, sodium-vapor streetlights reflected in puddles, shallow depth of field, three-quarter close portrait, 16:9.


OpenAI: GPT-6 Luna: Model A better captures the midnight riverside setting, sodium-lit puddle reflections, silver heat sheet, and requested 16:9 sports-photo composition, with the number 4821 clearly rendered. Model B conveys tearful relief especially well, but its bright, cool daytime look and square framing depart from key prompt details. (Second judge pass, order swapped — scores are the average of both: Model A better captures the midnight riverside atmosphere, sodium-lit reflections, and rain-soaked finish-lin | Anthropic: Claude Fable 5.1: Model A nails the 16:9 cinematic framing, dim n…
Velodrome machine detail
A custom track bicycle leaned against the pale cedar rail of the Narevik velodrome at dawn, every element rendered with crisp micro-detail: carbon fiber weave on the frame, brushed titanium chainring teeth, suede texture on the drops, tiny dust on the deep-section rims, numbered lane lines, and dew-beaded infield grass beyond; ultra-detailed commercial product photography, cool early light with long shadows, precise side composition, 16:9.


OpenAI: GPT-6 Luna: Model A better captures the full velodrome scene, cedar rail, numbered lane markings, and cool dawn light in the requested wide side composition. Model B has stronger close-up product detail and polish, but its setting and rail are much less faithful to the prompt. (Second judge pass, order swapped — scores are the average of both: Model A more clearly captures the velodrome setting, pale cedar rail, numbered lane, and wide side-on composition, while Model B offers a more striking close product | Anthropic: Claude Fable 5.1: Model A delivers the requested 16:9 side composi…
Goalkeeper glove check
A female handball goalkeeper in a moss-green kit crouches in front of the net during warmups, both hands fully visible as she tightens the strap on her left glove with the fingers of her right hand, showing all ten fingers clearly, realistic knuckles and nails, strong athletic but natural proportions from shoulders to knees; high-end editorial sports photography, clean indoor arena lighting, low sideline angle, sharp focus, 16:9.


OpenAI: GPT-6 Luna: Model A better captures the crouched goalkeeper warmup and the action of adjusting a glove strap in front of the net, though the gloves obscure some fingers and the hand anatomy is imperfect. Model B makes the fingers easy to count, but the strap is held between bare hands rather than tightened on a glove, and its close, square framing departs from the requested sports-photo composition. (Second judge pass, order swapped — scores are the average of both: Model A more convincingly shows a crouche | Anthropic: Claude Fable 5.1: Model A delivers the 16:9 editorial frame, a co…
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 clearly depicts the requested object colors and placements, with a balanced tabletop composition and the requested widescreen framing. Model B gets the arrangement mostly right, but its square framing and distracting reflections on the sphere make it less faithful and polished. (Second judge pass, order swapped — scores are the average of both: Model A follows the requested arrangement and colors while presenting a cleaner, wider tabletop composition with more convincing soft studio ligh | Anthropic: Claude Fable 5.1: Model A satisfies every constraint: matte green…
