Side by side

Anime & Cartoon Style An anime-style portrait of a samurai standing under pink cherry blossoms.

Flux 2 Pro 6 / 10 Ranked seventh despite its outstanding atmosphere because the hand-and-sword junction is a significant coherence weakness. The central equipment problem outweighs the otherwise excellent color and lighting.

Seedream 4.5 9 / 10 Ranks 1st of 12 through its exceptionally strong prompt fit, lighting, and integrated craftsmanship. Only minor softness in small decorative details prevents a perfect score.
Architecture & Interiors A traditional Moroccan riad courtyard with detailed zellige tilework, flowing fountain, citrus trees, and ornate woodwork. Morning light casting intricate shadow patterns.

Flux 2 Pro 5 / 10 Ranked 12th because attractive lighting cannot compensate for poorly resolved decorative surfaces and ambiguous furniture construction. It remains recognizable and relevant to the prompt, but its detail quality is substantially weaker than the rest of the set.

Seedream 4.5 8 / 10 Ranks 6th of 13, standing out for its bold palette and exceptionally effective patterned sunlight. It trails the higher-ranked entries primarily in fine-detail precision rather than atmosphere or prompt coverage.
Complex Scenes A family cooking together in a kitchen, each person busy with a different task.

Flux 2 Pro 6 / 10 Ranks ninth, with an appealing atmosphere but less precise physical staging and weaker task differentiation. Ambiguous lower-body support and the boy's unclear contribution prevent a stronger result.

Seedream 4.5 8 / 10 Rank 3 of 13: this is one of the clearest and most appealing interpretations of differentiated family tasks. Modest softness and a few less-defined contact points place it below the two leaders.
Ghibli style A young witch flying on a broomstick above a coastal town at sunset. Exact art style of 'Kiki's Delivery Service' by Studio Ghibli, with Miyazaki's character design and warm colors.

Flux 2 Pro 6 / 10 This ranks sixth, offering consistent warmth and appealing environmental storytelling. The substantial character-style deviation and somewhat stiff figure construction matter more than its otherwise clean presentation.

Seedream 4.5 9 / 10 Rank 1 of 10: the best combination of recognizable film-style character design, dynamic flight, and cinematic warmth. Minor background softness prevents a flawless score, but no other image balances the complete brief as effectively.

Minimalist logo for a sustainable coffee brand 'Evergreen Brew', single leaf motif, clean lines, vector style, white background. 'Evergreen Brew' contained as text in logo - Flux 2 Pro
Flux 2 Pro 8 / 10 Rank 4 of 12: a polished and contextually effective logo with strong construction. It falls behind the top three because the bean and large circular frame introduce unnecessary complexity.

Seedream 4.5 3 / 10 Ranks 13th of 13 because the central layout undermines the logo's primary function: clear brand recognition. It requires a fundamental recomposition rather than minor polishing.
Hands & Anatomy A close-up of two people shaking hands, both hands fully visible with five fingers each, in sharp focus against a blurred background.

Flux 2 Pro 5 / 10 Ranked 11th of 12. Good surface rendering cannot compensate for the malformed-looking lower grip, although the anatomy is less severely confused than in image 1107.
A close-up of two people shaking hands, both hands fully visible with five fingers each, in sharp focus against a blurred background. - Seedream 4.5
Seedream 4.5 7 / 10 Ranked 6th of 13, this is a convincing and polished handshake with minor stylization. Its principal limitation is incomplete digit visibility rather than a clear anatomical failure.
Photorealistic People & Portraits A 4K photo of an old fisherman with a weathered face and a pipe, grinning.

Flux 2 Pro 9 / 10 Ranked 1st of 12 for combining convincing age detail, an expressive grin, and an unmistakable working-fisherman setting. Its strong photographic execution and cohesive lighting make it the most complete response.
A 4K photo of an old fisherman with a weathered face and a pipe, grinning. - Seedream 4.5
Seedream 4.5 5 / 10 Rank 12 of 13: strong subject adherence, but noticeably weaker execution of photographic materials. The highly conspicuous pipe texture and processed clothing surface undermine an otherwise characterful face.
Surreal & Creative Prompts A waterfall that pours out stars and galaxies instead of water, illustrated in a cosmic fantasy style with vibrant space colors and dramatic lighting effects.
A waterfall that pours out stars and galaxies instead of water, illustrated in a cosmic fantasy style with vibrant space colors and dramatic lighting effects. - Flux 2 Pro
Flux 2 Pro 4 / 10 Ranked 12th because muddy layer separation and an unconvincing celestial overlay substantially weaken the central effect. The atmospheric mood offers some artistic value, but the muted colors and unclear pouring action miss important requirements.
A waterfall that pours out stars and galaxies instead of water, illustrated in a cosmic fantasy style with vibrant space colors and dramatic lighting effects. - Seedream 4.5
Seedream 4.5 7 / 10 Ranked sixth of 13, this is an evocative and substantially successful interpretation. Softer execution and the separation between ordinary water and celestial flow keep it out of the excellent tier.
Text in Images A technology magazine cover featuring the headline "Tech Innovations of 2025," clean modern design style.
A technology magazine cover featuring the headline "Tech Innovations of 2025," clean modern design style. - Flux 2 Pro
Flux 2 Pro 4 / 10 Rank 11 of 12: competent visual rendering cannot overcome pervasive typography failure. It retains the requested main headline, but falls well short of a credible, readable magazine cover.
A technology magazine cover featuring the headline "Tech Innovations of 2025," clean modern design style. - Seedream 4.5
Seedream 4.5 7 / 10 Ranked 6th of 13, this is a solid, readable cover with a well-rendered technological subject. Its competing background and mixed typography make it less polished than the more cohesive editorial designs.
Ultra Hard A famous cartoon character (e.g. Homer Simpson) rendered fully photorealistically as if a real human being, accurately preserving recognizable facial features and proportions
A famous cartoon character (e.g. Homer Simpson) rendered fully photorealistically as if a real human being, accurately preserving recognizable facial features and proportions - Flux 2 Pro
Flux 2 Pro 2 / 10 This is the most off-target result because neither a clear famous-character identity nor a fully photographic human transformation is achieved. Its polished modeling cannot compensate for missing those central requirements.
A famous cartoon character (e.g. Homer Simpson) rendered fully photorealistically as if a real human being, accurately preserving recognizable facial features and proportions - Seedream 4.5
Seedream 4.5 6 / 10 Ranks 4th of 11: genuine human facial details make it more successful than the predominantly CGI entries. Discontinuous anatomy and materials prevent it from reaching the stronger human portraits.
