Scenario by scenario

Both models ran the identical prompt under our fixed suite - the images are the published runs, shown exactly as generated.

Product material and lighting

Better here: GPT Image 2

Left is the stronger result overall. Right represents the half-fill level more precisely, but left has cleaner material rendering and more coherent premium product lighting.

  • Exactly one bottle and no extras: Tie. Both images show one upright transparent rectangular perfume bottle with no visible text, logo, plants, or separate objects.
  • Half-filled amber liquid: Right does better. Its liquid line sits close to the bottle’s halfway point, while the left bottle appears somewhat more than half filled within its main body.
  • Coherent refraction and reflection: Left does better. Its glass edges, amber refraction, and aligned reflection on the wet stone are cleaner and more internally consistent; the right bottle has warped upper glass and a visibly kinked dip tube.
  • Upper-left lighting and contact shadow: Left does better. The upper-left highlights carry consistently across the cap, shoulders, and liquid, with a plausible shadow extending rightward; the right lighting is directionally correct but produces harsher, less product-focused shadows.
Prompt & settings used

Prompt

A premium product photograph of exactly one transparent rectangular perfume bottle, half filled with amber liquid, standing upright on wet black stone. Light comes from the upper left, creating coherent refraction, a contact shadow, and one subtle reflection. No text, logo, plants, or extra objects.

Multilingual typography

Better here: Nano Banana Pro

Right follows the requested four-line poster layout exactly, while Left incorrectly wraps the first line and therefore displays five lines.

  • Exactly four centered text lines and no additional text: Right does better. It shows exactly four centered lines: "MOONLIGHT MARKET", "月光市集", "18 OCT", and "RIVER HALL". Left wraps "MOONLIGHT MARKET" across two lines, producing five visible text lines.
  • Exact wording and order: Right does better. Its four lines read exactly "MOONLIGHT MARKET", "月光市集", "18 OCT", and "RIVER HALL" in the requested order. Left contains the same words and characters, but "MOONLIGHT MARKET" is split into "MOONLIGHT" and "MARKET" rather than rendered as the required single line.
  • Required text colors: Tie. Both render "月光市集" in red and render "MOONLIGHT MARKET", "18 OCT", and "RIVER HALL" in black.
  • Legibility, spacing, and alignment: Right does better. Its four lines are clearly legible, centered on a shared axis, and consistently spaced. Left is legible and centered, but the wrapped "MOONLIGHT MARKET" creates an extra line and a less even overall arrangement.
Prompt & settings used

Prompt

Design a clean cream-colored vertical event poster. Show exactly four centered text lines and no other text: "MOONLIGHT MARKET", "月光市集", "18 OCT", and "RIVER HALL". Render "月光市集" in red and all other lines in black.

Human anatomy and contact

Better here: GPT Image 2

Left better satisfies all four anatomy and contact requirements. Its two hands are clearly presented, the fingers are more countable and naturally articulated, and their shaping contact with the clay is easier to read.

  • Exactly two fully visible hands: Left does better. It clearly shows one complete hand on each side of the bowl and no additional hands or people; Right shows two overlapping hands, but the lower hand is substantially obscured and not fully visible.
  • Each hand has exactly five distinct, naturally formed fingers: Left does better. Five fingers can be distinguished on each hand, though some overlap at the bowl; on Right, the overlapping pose and heavy occlusion make the fingers of the lower hand difficult to distinguish or count reliably.
  • Fingers, joints, and contact with the clay: Left does better. Both sets of fingers have coherent joints and visibly press against the bowl's inner wall. Right's upper hand is plausible, but the lower hand has an unclear, cramped intersection with the upper hand and bowl rim.
  • Clay bowl, spinning wheel, and shaping action: Left does better. The bowl and wheel are prominent, visible rotational blur conveys spinning, and both hands are actively shaping the interior. Right also clearly shows a bowl and spinning wheel, but the hand action is less legible because the hands overlap.
Prompt & settings used

Prompt

A photorealistic close-up of an adult potter shaping a clay bowl on a spinning wheel. Both hands are fully visible, each with five natural fingers touching the clay. No other people or hands. Soft window light.

Counting and attribute binding

Better here: Nano Banana Pro

Both outputs closely follow the prompt, but the right image communicates the specified wooden and ceramic materials more clearly while preserving the correct counts, placement, handle direction, and clean scene.

  • Object count and arrangement: Tie. Both images visibly show exactly three red cubes in a row on the left, two blue spheres on the right, and one yellow mug centered behind them.
  • Color, shape, and material binding: Right does better. Both bind the requested colors and shapes correctly, but the right image shows clear wood grain on the red cubes and a visibly ceramic, glazed surface on the mug; the left cubes have a smoother finish with less obvious wooden texture.
  • Mug handle direction: Tie. In both images, the mug handle is clearly attached on and extends toward the right.
  • No additional objects or text: Tie. Neither image contains any visible additional object or text.
Prompt & settings used

Prompt

On a matte gray table, exactly three red wooden cubes form a row on the left, exactly two blue glass spheres sit on the right, and one yellow ceramic mug stands centered behind them. The mug handle points right. No other objects or text.

Advertising composition

Better here: Nano Banana Pro

Right follows the text restriction and top-spacing instruction more precisely while preserving all required visual elements.

  • Exactly one silver shoe and orange trail: Tie. Both show one silver shoe in the lower-right, with a bright orange trail visibly entering from the bottom-left and curving through the composition.
  • Visible text: Right does better. Right contains only "RUN LIGHT" and "42 KM", both spelled correctly. Left also renders "RUN LIGHT" and "42 KM" correctly, but adds "AERO" on the shoe, violating the no-other-text requirement.
  • Top spacing and headline placement: Right does better. Its top area is clearly empty, with "RUN LIGHT" positioned immediately below the blank band in the upper-left. Left also leaves substantial empty space, but the headline begins noticeably farther down.
  • Visibility and hierarchy: Tie. Both keep the headline, badge, trail, and single shoe fully visible and establish a clear sequence from headline to badge to product.
Prompt & settings used

Prompt

Create a vertical social ad for a fictional running shoe named AERO. Keep the top 15 percent empty. Directly below it, place the headline "RUN LIGHT" in the upper-left. Show exactly one silver shoe in the lower-right, an orange trail curving from the bottom-left, and a round badge reading "42 KM". No other shoes or text.

Structured UI graphic

Better here: GPT Image 2

LEFT follows the requested structure exactly, while RIGHT violates the explicit requirement for no additional text.

  • Title and columns: Tie. Both render the exact title "CHOOSE YOUR PLAN" and exactly three columns labeled "STARTER", "PRO", and "TEAM".
  • Feature rows: Tie. Each column on both sides contains exactly three aligned rows labeled "PROJECTS", "STORAGE", and "SUPPORT".
  • Select buttons: Tie. Each column on both sides has exactly one blue button labeled "SELECT".
  • Alignment and additional text: Left does better. Its three columns are evenly aligned and contain no additional text. Right adds prohibited text including "5 active projects", "10 GB", "Email support", "20 active projects", "50 GB", "Priority email & chat support", "Unlimited projects", "200 GB", and "24/7 phone, email & chat support".
Prompt & settings used

Prompt

Create a clean horizontal pricing comparison graphic titled "CHOOSE YOUR PLAN". Use exactly three equal columns labeled "STARTER", "PRO", and "TEAM". Under each column, show exactly three aligned rows labeled "PROJECTS", "STORAGE", and "SUPPORT", followed by one blue button labeled "SELECT". White background, dark navy text, no additional columns or text.

Six-reference object binding and edit

Depends on the task

Both outputs visibly satisfy the requested object count and broad replacements. The reference images needed to distinguish exact object binding and base-scene preservation are not available, so neither side has a defensible overall advantage.

  • Criterion 1: Tie. Both show a dark navy-blue mug replacing the red mug and a folded green-and-white striped napkin replacing the white towel, in the same general tabletop arrangement. Exact reference matching and position preservation cannot be confirmed because the source references are not shown.
  • Criterion 2: Tie. Both show exactly one orange and one mustard-yellow hardcover notebook, with no visible green pear, blue notebook, red mug, or white towel remaining. Exact reference matching cannot be confirmed from these outputs alone.
  • Criterion 3: Tie. Both show exactly two lemons to the right of the mug, with no additional fruit or obvious duplicated object. The right image gives one lemon an attached green leaf, while the left gives neither lemon a leaf, but Reference 6 is unavailable to determine which is more accurate.
  • Criterion 4: Tie. Both retain a consistent wooden tabletop scene with natural wood grain, lighting, and shadows. Preservation of the exact Reference 1 camera, framing, and unchanged relationships cannot be assessed without seeing Reference 1.
Prompt & settings used

Prompt

Use Reference 1 as the base tabletop scene. Replace the red mug with the exact dark navy-blue mug from Reference 2 in the same position and orientation. Replace the folded white towel with the exact green-and-white striped napkin from Reference 3 in the same folded area. Replace the green pear with exactly one orange from Reference 4 in the same position. Replace the blue notebook with the exact mustard-yellow hardcover notebook from Reference 5 in the same position. Add exactly the two lemons from Reference 6 to the right of the mug. Preserve the wooden table, camera, framing, wood grain, lighting, shadows, and all other spatial relationships from Reference 1. Do not copy the white product backgrounds from References 2–6, duplicate any asset, or add other objects.

In-image text replacement

Depends on the task

Both outputs visibly satisfy the text requirements equally well. The source image is not provided, so the preservation-specific criteria cannot support choosing one over the other.

  • Exact text replacement: Tie. Both signs visibly read exactly "NIGHT OWL", with no visible remnants of earlier text.
  • No additional or malformed characters: Tie. Both render only the letters in "NIGHT OWL"; every character is clear and correctly formed.
  • Font, spacing, and perspective preservation: Tie. Both use clean uppercase sans-serif lettering aligned convincingly with the sign's perspective, but preservation of the original styling cannot be determined without the source image.
  • Material, lighting, and scene preservation: Tie. Both show plausible painted wood grain, shadows, and consistent storefront lighting, but which better preserves the original scene cannot be assessed without the source image.
Prompt & settings used

Prompt

Replace only the sign text with exactly "NIGHT OWL". Preserve the original font style, spacing, perspective, sign material, lighting, and everything else.

Multi-reference identity and garment transfer

Depends on the task

Both outputs are extremely similar and visibly complete the wardrobe replacement cleanly. Because the source references are unavailable, the key identity and exact-garment matching requirements cannot be verified, and the remaining visible criteria do not establish a clear winner.

  • Identity preservation: Cannot be assessed against Reference 1 because the reference image is not shown here. The two outputs depict the same apparent person, expression, hairstyle, pose, proportions, and similar framing, with only minor differences in crop and facial detail.
  • Jacket match: Cannot be assessed against Reference 2 because the isolated jacket is not shown here. Both outputs visibly depict a light-blue denim jacket with a cream shearling collar, bronze-colored buttons, flap chest pockets, and a red upper-sleeve patch; neither has a clear visible advantage without the reference.
  • Suit replacement: Tie. Both outputs fully show the person wearing the denim jacket, with no visible black suit jacket, ghost mannequin, or white product background.
  • Physical coherence: Tie. In both outputs, the hands sit naturally in front of the jacket, sleeves meet the wrists plausibly, fabric folds follow the bent arms, and the garment lighting is consistent with the softly lit gray scene. Neither shows a decisive visible coherence defect.
Prompt & settings used

Prompt

Use the portrait in Reference 1 for the person and the isolated jacket in Reference 2 for the garment. Dress the person from Reference 1 in the exact jacket shown in Reference 2. Preserve the person's identity, face, expression, skin, hair, hands, pose, body proportions, background, framing, and lighting from Reference 1. Preserve the jacket's material, color, collar, buttons, pockets, and sleeve patch from Reference 2. Do not copy the ghost mannequin or white product background.

Coherent scene relighting

Better here: Nano Banana Pro

RIGHT provides the more convincing coherent relighting, with stronger directional shadows and clearer separation between golden highlights and shaded areas. Object preservation remains unverified because the original image is not shown.

  • Warm golden-hour light clearly enters from the left window: tie. Both show warm sunlight coming through the left-side window; LEFT includes a visible low sun, while RIGHT shows strong window-shaped illumination extending across the wall and floor.
  • Highlights and shadow directions respond coherently to the new light source: RIGHT does better. Its plant, sofa, table, and lamp cast distinct shadows consistently toward the right, and the window-frame projections align with light arriving from the left. LEFT is broadly consistent but has softer, less clearly connected object shadows.
  • The result is more than a uniform yellow color filter: RIGHT does better. It preserves visibly cooler and darker shaded areas while adding localized golden highlights and directional light patches. LEFT also has directional lighting, but the warm tint is more uniformly spread across the room.
  • No furniture or decor is moved, added, removed, or redesigned: this cannot be assessed reliably without the original source image. Both outputs contain the same broad set of objects, but their geometry and placement differ, so the images alone do not reveal which model preserved the source more accurately.
Prompt & settings used

Prompt

Change the lighting to warm golden-hour sunlight entering from the left window. Do not move, add, remove, or redesign any object. Update highlights and shadows coherently.

Cross-ratio outpainting

Depends on the task

Both images visibly achieve a plausible 16:9 beach outpainting, while the key preservation requirements cannot be verified without the original image. Neither has a clear visible advantage in extension quality.

  • 16:9 format and natural side content: Tie. Both outputs are landscape frames with beach, ocean, and sky extending naturally to both sides; neither shows letterboxing or an obviously incomplete edge.
  • Complete original centered without cropping or stretching: Tie. The cabin and beach composition are centered in both, and neither appears visibly stretched, but preservation of the complete original cannot be confirmed because the source image is not shown.
  • Original cabin, shoreline, and internal composition unchanged: Cannot be assessed reliably from these outputs alone. The cabin details and shoreline differ between LEFT and RIGHT, but without the original image it is impossible to determine which, if either, remained unchanged.
  • No visible seams, mirrored filler, or repeated objects: Tie. Both extensions appear continuous across the sky, horizon, water, and sand, with no clear seam, mirrored region, or conspicuously repeated object visible.
Prompt & settings used

Prompt

Expand the canvas to a 16:9 landscape by naturally continuing the beach, ocean, and sky on both sides. Keep the complete original image centered without cropping, stretching, letterboxing, or modifying it.

Product preservation across scene change

Better here: GPT Image 2

LEFT more convincingly establishes the requested basketball-court scene and presents sharper product materials, stitching, grounding, and wet-surface interaction. Source-dependent preservation cannot be verified from the outputs alone.

  • Wet outdoor basketball court at dusk: Left does better. A hoop, backboard, chain-link fence, court lines, standing water, sunset sky, and illuminated court lights are all clearly visible; Right shows a wet lined surface at dusk, but the basketball setting is less immediately legible.
  • Sneaker consistency: Left does better on visible craftsmanship, with a clean silhouette, sharply resolved sole geometry, coherent stitching, and convincing leather and mesh materials. Right is also plausible but shows softer material detail and less distinct stitching. Exact consistency with the source sneaker and original camera angle cannot be assessed because the source image is not shown.
  • Black geometric side mark: The original mark is not shown, so whether either output leaves it unchanged cannot be determined. Both marks are readable, but Left renders its angular shape more crisply and with cleaner edges.
  • Physical coherence: Left does better. The shoe has a grounded contact shadow, a substantial wet-surface reflection, and lighting that combines cool foreground illumination with the warm dusk environment. Right has plausible contact and reflection, but the reflection is darker and less clearly resolved.
Prompt & settings used

Prompt

Place the sneaker on a wet outdoor basketball court at dusk. Preserve the exact sneaker shape, black geometric side mark, materials, stitching, sole geometry, and camera angle. Add physically coherent contact, reflections, and dusk lighting.
