Qwen-Image 2.1 vs FLUX.2 [dev] — 64 images, side by side

A rain-slicked neon-lit street at night: under a glowing red neon sign that reads exactly "REDLINE GARAGE" with a smaller white neon line "TUNING · SERVICE · 24/7" beneath it, a white Porsche 911 Turbo with an itasha sakura livery of lilac cherry blossoms and dark brown branches is parked on wet asphalt, petals floating in the air, neon reflections everywhere, ultra-detailed cinematic wallpaper.

Qwen renders both neon lines letter-perfect on both cards. This prompt produced the best image of the run (9/10 on both cards).

Dark fantasy movie poster: the title "BLADE OF RUIN" in cracked molten-metal letters at the top and the tagline "ONE SWORD. NO MERCY." beneath it, a colossal greatsword driven into shattered ground, a bloodied warrior kneeling beside it, burning sky and drifting embers, ultra-detailed wallpaper-grade print design.

Extreme close-up of a giant sword blade clamped in a CNC milling machine, the brushed steel engraved with the text "FORGED NOT PRINTED" and a smaller serial "UNIT 0421", sharp metal burrs around the letter grooves, coolant mist and sparks, workshop lighting, shallow depth of field, wallpaper-grade macro detail.

Letter-perfect engraving on both Qwen cards. Single documented slip: on the 16 GB Qwen build, seed 4210, "NOT" drifts into a symbol plus a T.

A battle-scarred warrior in torn dark clothing wields three katanas in three-sword style — one in each hand and the third clamped between his teeth — blood splatter across his face, moonlit temple rooftop, torn banners whipping in the wind, dynamic action pose, hyper-detailed dark anime illustration, wallpaper-grade detail.

Four legendary tuner cars parked side by side in a rain-soaked neon underground car park, from left to right: a bayside blue Nissan Skyline GT-R R34, a black BMW M3 E46 with wide arches, a pearl white Ferrari 458 with a Liberty Walk widebody kit and giant rear wing, and a red Mazda RX-7 FD, reflections shimmering on wet concrete, cinematic night photography, wallpaper-grade detail.

Top-down aerial view of a midnight city tunnel during a drift run, exactly six tuner cars sliding in formation through tire smoke, all white liveries except the third car from the left which is bayside blue, headlight beams cutting through the smoke, long light trails on wet asphalt, cinematic, wallpaper-grade detail.

Hardest prompt for both models: six moving cars plus a color order to count. Counting fails on both (Qwen 5-6, FLUX 2-4).

Epic cinematic film still: a blood-soaked soldier in battered modern combat armor stands alone on a rain-soaked ruined street, defiantly facing a colossal horned demon the size of a cathedral with burning amber eyes and bone-cracked armor plates towering over collapsed skyscrapers, blood and embers swirling in the storm, volumetric god rays, anamorphic lens flare, hyper-detailed dark fantasy blockbuster, wallpaper-grade detail.

Cinematic anime key visual: a beautiful young swordswoman with long silver hair and a scar across her cheek, blood droplets suspended in the air as she sheathes her glowing katana on a neon skyscraper rooftop at midnight, torn black coat whipping in the wind, neon megacity bokeh below, dynamic low-angle shot, masterpiece anime illustration, wallpaper-grade detail.
