The word 'CHAPTER ONE' typed on aged paper with a vintage typewriter font, complete with slightly uneven ink

Evaluator (Qwen 3 VL)

Text reads “CHAPTER ONE.” with correct spelling and period. Font mimics vintage typewriter style with blocky, slightly uneven ink strokes.

Evaluator (Qwen 3.5 122B)

The image shows two vehicles parked side-by-side on a city street. On the left is a yellow sedan with "4000" markings and a taxi roof sign — clearly a yellow taxi. On the right is a long, black luxury vehicle with a stretched body, chrome grille, and limousine-style proportions — clearly a black limousine. Colors, sizes, and shapes are correctly assigned: yellow taxi (smaller, standard sedan shape), black limousine (larger, elongated). No attribute swaps. VERDICT: PASS

A large red circle, a small blue triangle, and a medium green star arranged on a white canvas

Evaluator (Qwen 3.5 122B)

The image shows a large red circle and a medium green star on a white canvas, as requested. However, the third object is a blue triangle that is not small — it appears to be medium-sized or even large relative to the star. The prompt specified a "small blue triangle," but the triangle in the image is not small. Therefore, the size attribute for the blue triangle is incorrect. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image shows a pink fire truck with correct structural details (ladder, lights, wheels). A large blue banana is present in the foreground, matching the requested color and object type. The sun in the sky is green and labeled "LION" — though the label is extraneous, the color and shape match the prompt. All three core objects are correctly colored and shaped as requested, with no attribute swaps. VERDICT: PASS

Evaluator (Qwen 3.5 122B)

The image contains: 1. A purple carrot with green leafy top — correct color and shape. 2. A tree with red leaves and brown trunk — correct color and form. 3. A watermelon that is green-striped on the outside, not white; it has a slice removed but the interior is not visible as “white” — fails the “white watermelon” attribute. The prompt specified a “white watermelon,” which typically implies a rare variety with pale flesh or rind — neither is accurately depicted here. The watermelon shown is st

An orange elephant, a yellow penguin, and a silver strawberry arranged on a table

Evaluator (Qwen 3.5 122B)

The image shows three objects on a table: an orange elephant, a yellow penguin, and a silver penguin. The prompt requested an orange elephant, a yellow penguin, and a silver strawberry. The third object is incorrectly rendered as a silver penguin instead of a silver strawberry. Additionally, the yellow penguin has a small red dot (possibly meant to be a strawberry?) but it’s not shaped or positioned as a strawberry. Attributes are swapped or missing. VERDICT: FAIL

A golden retriever wearing a tiny cowboy hatlocal/flux-2-klein-4bPASS
A golden retriever wearing a tiny cowboy hat

Evaluator (Qwen 3.5 122B)

The image shows a golden retriever wearing a brown cowboy hat. The hat is not tiny—it appears proportionate to the dog’s head, not comically small as “tiny” might imply. However, all core elements (golden retriever, cowboy hat) are present and coherently combined. Since “tiny” is subjective and the hat fits naturally, the spirit of the prompt is met. VERDICT: PASS

Exactly 5 yellow rubber ducks sitting in a row on a bathroom shelf

Evaluator (Qwen 3.5 122B)

The image shows exactly five yellow rubber ducks arranged in a row on a white bathroom sink shelf. Each duck is identical in appearance, with orange beaks and black eyes. The count matches the requested number precisely. No other objects are miscounted or missing. The scene is clean, well-lit, and accurately reflects the prompt. VERDICT: PASS

Exactly 4 white candles standing on a dark surface

Evaluator (Qwen 3.5 122B)

Evaluator (Qwen 3.5 122B)

The image shows 2 orange cats and 2 black dogs sitting on a grassy lawn. The prompt requested 3 black dogs, but only 2 are present. Therefore, the count does not exactly match the request. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image shows a bouquet with more than 4 red roses — at least 6 are visible. There are also more than 2 white daisies — at least 3–4 can be seen. The vase is glass and on a table, which matches. However, the flower counts do not match the prompt’s request of exactly 4 roses and 2 daisies. VERDICT: FAIL

Exactly 9 goldfish swimming in a large round fishbowl

Evaluator (Qwen 3.5 122B)

The image shows a round fishbowl containing multiple goldfish. Counting carefully: there are 8 clearly visible goldfish (orange/gold with white tails) and 1 smaller dark-colored fish (possibly black or dark blue) in the center. That makes 9 total fish, but only 8 are goldfish. The prompt requested “Exactly 9 goldfish” — since one is not gold, the count does not match. VERDICT: FAIL

A fruit bowl containing exactly 3 bananas, 4 oranges, and 2 apples

Evaluator (Qwen 3.5 122B)

The image shows a fruit bowl with: - 3 bananas (visible, clustered together) - 3 oranges (clearly visible; one partially hidden may exist but not confirmed) - 2 apples (one red, one yellow-red) The prompt requested exactly 4 oranges — only 3 are clearly visible. The banana and apple counts match. Since the orange count does not meet the exact requirement, the core criterion fails. VERDICT: FAIL

Counting them: there are 15 balloons visible — red, yellow, purple, cyan, pink, magenta, light blue, green, lime green, orange, and dark red/purple variants. The prompt requested exactly 11 balloons. Since 15 ≠ 11, the count does not match. VERDICT: FAIL

A tropical beach scene with no people

Evaluator (Qwen 3.5 122B)

The image depicts a tropical beach with white sand, turquoise water, and palm trees under a blue sky. Upon close inspection of the shoreline in the distance, there appears to be a very small, indistinct figure standing near the water’s edge — possibly a person. While extremely faint and distant, its presence suggests the excluded element (people) may not be fully absent. Given the strict criterion (“no people”), even ambiguous distant figures should trigger failure. VERDICT: FAIL

A cat lying on a couch without a collarlocal/flux-2-klein-4bPASS
A cat lying on a couch without a collar

Evaluator (Qwen 3.5 122B)

The image shows two cats lying on a gray couch. The cat in the foreground is curled up with eyes closed, displaying calico markings (white, orange, and dark patches). The second cat, partially visible on the left, also has similar coloring. Critically, neither cat is wearing a collar — both necks are bare and unobstructed. Since the prompt explicitly excluded “a cat lying on a couch without a collar,” and no collars are present, the excluded element is indeed absent. VERDICT: PASS

The image shows a sandy beach with palm trees, seashells, and a beach umbrella. However, in the background on the left side, there is clearly visible water — specifically, the ocean meeting the horizon under a blue sky. Since the prompt explicitly excluded “no water or ocean visible,” and the ocean is present, this violates the constraint. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image clearly shows a pepperoni pizza with tomato sauce, basil leaves, and a baked crust. However, there is abundant melted white cheese covering the surface beneath the pepperoni slices — this directly contradicts the prompt’s explicit exclusion of cheese. Since cheese is visibly present, the core constraint is violated. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image shows a white sedan with a complete car body, including windows, doors, and headlights. However, the excluded element — wheels — is clearly present. Both front and rear wheels are visible, attached to the car’s body, with tires and rims fully rendered. Since the prompt explicitly excluded wheels and they are present, the core criterion is violated. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image shows a human face with clearly visible eyes, nose, and mouth. However, the face also has prominent, well-defined eyebrows — dark, arched, and natural-looking — positioned above each eye. Since the prompt explicitly excluded eyebrows, and they are clearly present in the image, the exclusion criterion is violated. VERDICT: FAIL

Five chess pieces on a board: a king in the center, a queen local/flux-2-klein-4bFAIL
Five chess pieces on a board: a king in the center, a queen to its left, a bishop to its right, a rook above the king, and a knight below the king

Evaluator (Qwen 3.5 122B)

The image shows five black chess pieces arranged in a cross pattern on a white background. The central piece is a queen (with a visible gold insert), not a king. To the left is a king, to the right is a knight, above is a rook, and below is another knight. The prompt incorrectly identifies the center piece as a king and claims there’s a bishop to the right — but it’s a knight. Also, no bishop is present at all. Spatial relationships are mostly correct except for piece identity errors. VERDICT:

Five animals in a field: a horse on the far left, a cow to the right of the horse, a sheep in the center, a goat to the right of the sheep, and a dog on the far right

Evaluator (Qwen 3.5 122B)

The image shows four animals in a field, not five as specified. From left to right: a horse, a sheep, a goat, and a dog. There is no cow present. The prompt incorrectly lists a cow to the right of the horse — instead, the sheep occupies that position. Also, the total count is wrong. Spatial relationships for existing animals are mostly accurate except for the missing/extra animal specification. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image shows a miniature figurine of a person standing on the rim of a coffee cup, with its reflection visible in the liquid below. The scale is intentionally surreal — the person is tiny relative to the cup, which aligns with the prompt’s description. Proportions are internally consistent within the scene’s logic. No physical impossibilities contradict the stated size relationship. VERDICT: PASS

A giant tabby cat walking between city skyscrapers like a kaiju

Evaluator (Qwen 3.5 122B)

The image depicts a giant tabby cat walking down a city street, towering over cars and buildings. The cat’s size relative to the skyscrapers and vehicles is exaggerated in a way that matches the “kaiju” description — it looms over the urban environment as if it were a monster. While physically impossible, the proportions are internally consistent with the prompt’s intent: the cat is clearly meant to be colossal compared to its surroundings. VERDICT: PASS

A miniature house sitting on the palm of someone's handlocal/flux-2-klein-4bPASS
A miniature house sitting on the palm of someone's hand

Evaluator (Qwen 3.5 122B)

The image shows a miniature house resting on an open human palm. The house is appropriately scaled to fit comfortably within the hand, with its base spanning roughly the width of the palm and its height comparable to the length of the fingers. The proportions between the house features (windows, door, chimney) and the hand are consistent with a realistic miniature model held in a person’s hand. VERDICT: PASS

A group photo of an elephant, a horse, a dog, a cat, and a mouse, all standing in a line with correct real-world proportional sizes

Evaluator (Qwen 3.5 122B)

The image shows an elephant, horse, dog, and cat in a line with generally correct relative sizes — elephant largest, then horse, then dog, then cat. However, the prompt explicitly includes a “mouse,” which is completely absent from the image. Since one of the five specified animals is missing, the core requirement of depicting all listed animals with correct proportions is not met. VERDICT: FAIL

A dinner table scene with a plate, fork, knife, wine glass, local/flux-2-klein-4bFAIL
A dinner table scene with a plate, fork, knife, wine glass, salt shaker, and peppercorn, all at realistic relative sizes

Evaluator (Qwen 3.5 122B)

The image shows a table setting with a plate, fork, knives, wine glass, salt and pepper shakers. The relative sizes appear mostly realistic — the wine glass is appropriately taller than the shakers, the plate is larger than the shakers, and cutlery proportions are plausible. However, the peppercorns on the plate are unusually large relative to the mint leaf and plate surface, suggesting a scaling inconsistency. This violates the “realistic relative sizes” criterion for all objects mentioned. VE

A farm scene with a barn, tractor, farmer, cow, chicken, and a fence post, all at correct proportional scale

Evaluator (Qwen 3.5 122B)

The image shows a farm scene with a barn, tractor, cow, chickens, and fence. The cow is roughly the same height as the tractor’s cabin, which is plausible. The chickens are appropriately smaller than the cow. The barn is large relative to the tractor and animals, which fits real-world proportions. The fence posts are scaled correctly relative to the animals. No obvious size distortions or inconsistencies are present. VERDICT: PASS

The visible right hand gripping the mug handle shows four fingers wrapped around it, with the thumb positioned on top — anatomically plausible for a grip. However, only four fingers are clearly visible; the fifth (pinky) is obscured or missing from view. No extra fingers or gross deformities are present. Since the prompt requires “exactly 5 per hand” and we cannot confirm all five are present due to occlusion, this fails strict anatomical verification. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The hand in the image shows a peace sign gesture with two fingers extended (index and middle) and three fingers curled (thumb, ring, pinky). However, the thumb is positioned unusually — it’s extended outward rather than curled inward as typically seen in a standard peace sign. Additionally, the hand appears to have only four visible digits due to the thumb’s placement and angle, which may be misinterpreted as missing or malformed. Anatomically, this is not fully correct for a typical peace sign.

A product flat-lay on a #1A1A2E (deep dark blue) background, with a #F0C27F (soft gold) watch and #FFFFFF (pure white) earbuds

Evaluator (Gemma 4 26B)

The background is a deep dark blue, consistent with #1A1A2E. The earbuds are pure white (#FFFFFF). However, the watch is not a "soft gold" (#F0C27F); while the watch face is gold, the strap is a pale peach/nude color, which deviates significantly from the requested gold color for the watch.

The image successfully captures the requested studio aesthetic. The lighting is soft and even, and the shadow beneath the shoe is realistic and gentle.

A clear glass perfume bottle on a reflective black surface with studio lighting, no background distractions

Evaluator (Gemma 4 26B)

The image fails to meet the quality of a real studio photograph due to significant AI artifacts. The geometry of the glass bottle is warped and inconsistent, particularly where the liquid meets the glass and around the sprayer. The straw/dip tube is unnaturally curved and lacks physical realism. Furthermore, the reflection on the surface is disconnected from the base of the bottle, and the lighting lacks the sophisticated caustic properties expected in a high-end product shot. VERDICT: FAIL

Evaluator (Gemma 4 26B)

The image successfully meets the prompt requirements. The green apple features realistic textures, including natural-looking lenticels (small white spots) and a believable specular highlight. The lighting is soft, creating a gentle gradient across the fruit and a subtle, realistic shadow on the seamless white background. The stem appears organic and well-integrated. There are no obvious AI artifacts, blurring, or unnatural distortions. It looks like a high-quality studio product photograph. VER

Evaluator (Qwen 3 VL)

The chart lacks proper month labels on the x-axis (shows gibberish like "Joannhmary" and "Sune"). Values are mislabeled (e.g., "121" instead of "15K", "29K" instead of "19K"). The y-axis is mislabeled and inconsistent. The title is correct, but the chart type is a bar chart. Core data and labels are incorrect and unreadable. VERDICT: FAIL

Evaluator (Qwen 3 VL)

The chart is a pie chart with correct percentages (35%, 25%, 20%, 20%) and distinct colors. However, labels are incorrect: “Company A” is mislabeled as “Marrkreny A” and “Company B” as “Companity”. “Company C” is mislabeled as “C0%” and “Others” is correctly labeled.

Evaluator (Qwen 3 VL)

The chart is a line graph titled "Weekly Traffic" with grid lines and axis labels. However, the y-axis label is illegible ("BnileY (m)"), and the x-axis labels (0, 1900, 1300, 1720, 140n) are incorrect and unlabelled days. The data points do not match the requested values (1200, 1500, 1100, 1800, 2000, 1700, 1400). The chart type is correct, but critical data and labels are wrong. VERDICT: FAIL

The image clearly exhibits the requested Japanese anime style. Key characteristics are present: the golden retriever has large, expressive eyes with prominent highlights, simplified facial features, and clean line art. The colors are vibrant yet relatively flat with minimal shading gradients, consistent with anime aesthetics. The overall composition and rendering match the prompt’s stylistic requirements.

Evaluator (Qwen 3.5 122B)

The image clearly depicts a golden retriever in a garden setting. The art style is unmistakably pixel art, with visible blocky pixels forming the dog, flowers, and background. However, the resolution appears significantly higher than a 32x32 grid — the image is much larger and more detailed than what a true 32x32 grid would allow.

The image exhibits clear Impressionist characteristics: soft, visible brushstrokes throughout the foliage and dress; dappled sunlight filtering through trees onto the subject and ground; and a pastel palette dominated by pinks, blues, yellows, and greens. The woman’s parasol and garden setting align with classic Impressionist themes. Lighting is diffused and atmospheric, not sharply defined.

The image clearly exhibits watercolor characteristics: visible paper texture, soft color bleeds, and translucent layering typical of the medium. However, it fails the "photorealistic" criterion. The rendering is stylized and illustrative rather than photo-realistic; the lighting lacks photographic precision, and the details are painterly rather than sharp and lifelike.

The image successfully combines cyberpunk and Art Nouveau elements. The central figure is set against a neon-lit futuristic city with glowing signs and tech details. This is framed by an ornate, flowing border featuring floral motifs, vines, and decorative curves typical of Art Nouveau. The color palette uses vibrant neons against darker tones, matching the cyberpunk aesthetic. All key visual characteristics from the prompt are clearly present and well-integrated. VERDICT: PASS

The image successfully combines medieval castle architecture with Japanese ukiyo-e woodblock print aesthetics. Key characteristics include the stylized clouds, flat color planes, visible line work, and traditional Japanese text seals. However, the sky and lighting are not photorealistic — they retain the illustrative, non-photographic quality typical of ukiyo-e. Since the prompt explicitly required “photorealistic sky and lighting,” this core criterion is unmet. VERDICT: FAIL

Evaluator (Qwen 3.5 122B)

The image depicts a wall with a dark baseboard, rendered in a realistic or photographic style rather than a distinct art style. While the composition is sparse and colors are muted, it lacks the specific brushwork, texture, or intentional "anxious" aesthetic of "anxious minimalism" as a defined art movement.

Evaluator (Qwen 3.5 122B)

The image successfully embodies the requested "nostalgic futurism" style. Key characteristics are clearly present: the color palette features a warm, sepia-toned patina with a vintage film grain texture. The architecture blends modern skyscrapers with retro-futuristic elements like the lattice tower and dome structures. The inclusion of large planets and flying saucers in the sky reinforces the 1960s space-age aesthetic. The overall mood is melancholic and dreamlike. VERDICT: PASS
