Head to head: FLUX 2 vs Ideogram V4.5 Edit
FLUX 2 vs Ideogram V4.5 Edit
By Ryan Merket · Published
A task-by-task comparison of FLUX 2 and Ideogram V4.5 Edit across expressive scenes, fine material detail, anatomy, named art styles, perspective, and exact counting. The results reveal where each model follows a tightly specified brief—and where visual polish isn’t enough.
FLUX 2’s advantage came from getting the central action and composition right. It made the chef’s first sip and relief unmistakable, rendered the jacquard napkin and tabletop details with greater crispness, and kept the library aisle centered on a clean vanishing point. In the citrus macro, it also made the sugar crystals and juice vesicles the focus, though the fruit read more as lime than bergamot. It was strongest when prompts demanded disciplined arrangement: FLUX showed exactly seven cups in a straight row without extra objects, while Ideogram also showed seven but added saucers and a spoon. Ideogram, by contrast, took the wins for the friendship-bracelet scene and the ukiyo-e fishing boat, where its handling of the action and its recognizable style were more convincing. The dockside chowder scene was a genuine split: FLUX better controlled the receding stools and one-point harbor-canteen layout; Ideogram better conveyed the steaming vat, dawn warmth, and lived-in atmosphere. That tie doesn’t change the broader pattern. FLUX won five tasks to Ideogram’s two, with an 8-point aggregate lead and an limited confidence verdict. **Final call: FLUX 2 wins.** Its edge is not universal—Ideogram has clear strengths in named style and candid hand interaction—but FLUX was more dependable across precise compositions, material detail, and counting.
Relief After First Sip
A painterly portrait of an exhausted pastry chef in a flour-dusted pistachio apron pausing in a back-alley doorway at sunrise, eyes half-closing and shoulders dropping in unmistakable relief as she takes the first sip from a chipped enamel cup of thick hot chocolate; warm rim light catching steam and stray curls of hair, expressive face as the clear focal point, softly textured realist oil painting style.
OpenAI: GPT-6 Luna: Model A more directly captures the first sip and unmistakable relief, with the flour-dusted apron, chipped cup, steam, sunrise rim light, and expressive face all prominent. Model B has a lovely painterly alley setting, but the chef is holding the cup away from her mouth and her expression reads less clearly as relief. (Second judge pass, order swapped — scores are the average of both: Model A more clearly captures the first sip, closed eyes, rising steam, flour-dusted apron, and sunrise rim ligh | Anthropic: Claude Fable 5.1: Model A delivers the expressive face as the cle…
Jacquard Tea Detail
An oil painting of a midnight tea service on a walnut table, centered on a folded saffron-and-ink jacquard napkin beside a pewter teapot and two cracked cardamom buns, rendered with exceptionally crisp fabric weave, brushed metal tarnish, flaky pastry layers, and scattered tea leaves with no smudging; cool window light from the left, intimate tabletop composition, 16:9.
OpenAI: GPT-6 Luna: Model A more closely matches the crisp jacquard weave, tarnished pewter, flaky buns, scattered tea leaves, and cool left-side window light, with a tightly focused tabletop composition. Model B has a painterly oil appearance and clearly split buns, but its softer rendering and less distinctive napkin pattern fall short of the prompt’s sharp textile detail.

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 friendship bracelet being handled alongside loose threads, with a natural candid setting and pleasing shallow depth of field. Model A has a clean close-up and plausible hands, but the activity reads more like holding a short cord than tying a bracelet. (Second judge pass, order swapped — scores are the average of both: Model B has a more natural candid feel, with both hands plausibly holding the bracelet and loose threads in a softly lit 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 B more clearly shows a fishing boat riding the cresting wave, with bold ukiyo-e outlines, stylized foam, and a restrained indigo-and-cream palette. Model A has a lovely dawn atmosphere, but its most prominent boat sits on calmer water rather than riding the wave. (Second judge pass, order swapped — scores are the average of both: Model B more directly depicts a fishing boat riding the cresting wave and closely matches the requested muted indigo-and-cream ukiyo-e look.

Macro Citrus Bead
A photorealistic macro close-up of a single candied bergamot wedge balanced on the rim of a smoky cobalt cocktail glass, shot with a true macro lens so the sugar crystals and tiny translucent juice vesicles fill the frame while the bar shelves behind melt into creamy circular bokeh; low amber speakeasy lighting, razor-thin depth of field, dramatic side composition, 16:9.
OpenAI: GPT-6 Luna: Model A closely delivers the requested macro view, with prominent sugar crystals and juice vesicles, a cobalt glass, and warm circular bokeh, though the citrus reads more like lime than bergamot. Model B is polished and atmospheric, but its wider framing and lack of visible sugar detail miss the central macro-citrus focus.

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 more directly delivers the empty, centered one-point-perspective aisle, with shelves and books receding consistently toward a clear vanishing point. Model B is richly detailed, but the ladder, open book, and furniture make the aisle feel less empty and distract from the perspective study.

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 presents exactly seven clearly separate cups in a clean, straight row on white marble. Model B also has seven cups, but the saucers and apparent utensil around the center cup add unrequested elements and make the arrangement less consistent.

Dockside Chowder Perspective
A realistic harbor canteen interior at dawn showing a towering copper vat of fennel chowder in the foreground, a line of seven mismatched stools receding toward a back counter, and rain-streaked windows revealing moored trawlers outside, all built with strict one-point perspective and believable scale so the ladles, bowls, stools, tiled floor, and distant boats align naturally without warping; pale blue morning light, cinematic wide shot, 16:9.
OpenAI: GPT-6 Luna: Model A more closely follows the requested one-point harbor-canteen composition, with a towering foreground vat, stools receding in a clear line, and rain-streaked windows framing trawlers. Model B is richly detailed, but its stools are scattered rather than aligned in a receding row, and the overall composition feels less controlled. (Second judge pass, order swapped — scores are the average of both: Model B better captures the steaming chowder vat, warm dawn atmosphere, and lived-in harbor can | Anthropic: Claude Fable 5.1: Model A delivers the pale blue dawn light, rain…
