Same method as round one: read the live site, lock one prompt per concept, push that identical prompt through every image model Moby has, and change nothing but the model. Round one was ten images and produced a clean story. Sixty images tells a different one — and the difference is the point.
“Text rendering is solved. 10/10, zero garbling. You can stop budgeting retries for that.”
At sixty images, text broke eight times. Nano Banana Pro garbled a tube into “FIRASE WASH / 183 YEHV OHARSE”, mirrored wordmarks in three separate briefs, and leaked my own prompt's style words into an ad as headline copy. Seedream misspelled the brand as “HARY'S” and turned “Home Try-On” into “Home Try You!”. Ten samples couldn't see it. This is exactly the seed-luck risk I flagged — it just landed on the conclusion instead of the caveat.
“Not one model honoured slab-serif on Harry's. Font choice is the thing to composite in post, not prompt for.”
Too broad. On the graphic promo layout, GPT Image 2 rendered a clean slab-serif wordmark and headline, and Grok did too. The failure was never “models can't do slab” — it's that typography instructions survive on graphic layouts and get overridden inside photographic scenes, where the model defaults to whatever a real bottle or storefront would plausibly wear. That's a far more useful rule, and only six concepts could expose it.
Text score counts briefs where every rendered character is correct and correctly oriented, judged by me at full resolution. Verdicts are my read, not a measurement.
| Model | Text integrity | Typography instruction | Product form | Brand recall | The take |
|---|---|---|---|---|---|
| GPT Image 2 gpt-image-2 | 12 / 12 clean | Serif and slab honoured | Held every silhouette | Deepest real brand recall — also the biggest IP flag | The default. Only model with zero text defects across 12 briefs. |
| Nano Banana 2 gemini-3.1-flash-image-preview | 11 / 12 clean | Defaults to sans | Held the cylinder | Mammoth mark; invented a real toothpaste brand | Strong volume workhorse. One mirrored razor handle. Adds periods to your copy. |
| Nano Banana Pro gemini-3-pro-image | 8 / 12 clean | Defaults to sans | Held the cylinder | Rendered a real Amazon logo unprompted | Best light in the run, worst text. Mirroring in 3 briefs plus prompt-leak. Do not trust with legible copy. |
| Grok Imagine grok-imagine-image-quality | 11 / 12 clean | Slab only on graphic layouts | Drifts the bottle in 4 of 6 | Clean | Use for graphic promo layouts, not product truth. Adds objects you didn't ask for. |
| Dola Seedream 5.0 Pro dola-seedream-5-0-pro-260628 | 10 / 12 clean | Mixed serif / sans | Drifted round 1, mostly held round 2 | Clean | Bright and airy, but it garbled “Home Try-On” and misspelled the brand itself. |
Navy, serif, warm neutral, understated. The soft brief — and the one that flatters every model until you ask it to spell something.
#1B2C6BCan the model hold a human face, real skin, and a product on-face without drifting?
Premium eyewear advertisement, square format. Tight editorial crop of a woman's face from mid-forehead to collarbone, wearing round tortoiseshell acetate eyeglasses with warm amber grain and thin gold rivets. Real visible skin texture and a few freckles, relaxed closed-mouth expression, dark hair tucked behind one ear, matte oatmeal knit sweater. Bright soft natural daylight from a large window camera-left with gentle falloff, seamless warm-greige studio backdrop. Shallow depth of field with crisp focus on the frame front. Warm neutral palette of oat, greige and deep navy. Small letterspaced deep-navy serif capitals in the top left corner read WARBY PARKER. Clean serif text in the lower left reads Starting at $95. Calm, refined, uncluttered, premium print-campaign quality, photorealistic.
01.1
Drift
Warm greige field, freckled skin, tortoise round frames all on brief. Wordmark rendered sans, not the briefed serif. Added a period to “Starting at $95.”
01.2
Drift
Three-quarter profile looking off-camera, window light camera-left correct. Wordmark sans again. Copy exact, no period.
01.3
On brief
Only model to render the wordmark as letterspaced serif capitals as briefed. Richest acetate mottling and visible gold rivets. Copy reproduced exactly.
01.4
Drift
Composition solid, warm palette held. Wordmark bold sans. Frame geometry reads slightly oversized against the face.
01.5
Drift
Curly hair, gold bridge detail, pleasant light. Both the wordmark and the price line rendered sans — double miss on the serif instruction.
A counting and arrangement test: exact item lists, precise grids, contact shadows.
Premium eyewear advertisement, square format. Overhead flat-lay of five pairs of eyeglasses arranged in a precise evenly spaced row on a seamless warm-greige paper surface: tortoiseshell round, deep navy rectangle, crystal-clear square, matte black oval, and pale rose acetate. Soft diffused overhead studio light, delicate contact shadows beneath each frame, subtle specular highlights on the polished acetate. Warm neutral palette of oat, greige and deep navy, generous negative space around the row. Small letterspaced deep-navy serif capitals in the top left corner read WARBY PARKER. Clean serif text in the lower left reads Starting at $95. Orderly, refined, editorial, premium print-campaign quality, photorealistic.
02.1
On brief
All five specified frames correct in colour and order. Clean contact shadows. Wordmark sans; period added to copy.
02.2
On brief
All five frames correct, cleanest surface and shadow of the set. Wordmark sans.
02.3
On brief
All five frames correct, wordmark serif as briefed, and micro-text “WARBY PARKER” legible on the temples. Copy exact.
02.4
Drift
All five frames correct, but the price line wraps to two lines and runs largest in the set — layout drift against a single-line instruction.
02.5
Drift
Five frames correct. Largest wordmark of the set and rendered sans; price line also sans. Acetate reads slightly plastic.
Pure graphic layout. Typography instruction is the whole brief here.
Premium eyewear advertisement, square format. Bold graphic promo layout on a flat deep navy field. Centered large white serif headline reads Eyewear that starts at $95. Below it, a single pair of tortoiseshell acetate eyeglasses floats in three-quarter view, lit with soft studio light and casting a subtle drop shadow onto the navy. A white pill-shaped button near the bottom holds deep-navy uppercase text SHOP NOW. Small letterspaced white serif capitals in the top left corner read WARBY PARKER. Confident, clean, generous negative space, crisp typographic hierarchy, premium campaign design, photorealistic product rendering.
03.1
On brief
Navy field, serif headline, pill button all correct. Wordmark sans. Period added to the headline.
03.2
Drift
Headline pushed to all caps, which was never briefed. Wordmark sans. Adds “WARBY PARKER” micro-text to the temple.
03.3
On brief
Wordmark serif, headline serif, copy exact with no invented punctuation. Temple micro-text and rivets present. Tightest execution in the concept.
03.4
Drift
Wordmark rendered centre-top, not the briefed top-left corner — a position miss. Glasses shown folded from the rear.
03.5
On brief
Serif wordmark and serif headline, copy exact. Pill button correct. Cleanest negative space of the five.
Hard light, cast shadows, and prop staging away from the brand's usual set.
Premium eyewear advertisement, square format. Sunlit summer scene of tortoiseshell acetate sunglasses with gradient green-tinted lenses resting on a folded sand-colored linen towel beside a woven straw hat brim. Hard midday sunlight from the upper left casting crisp palm-frond shadows across a warm sandstone surface, small grains of sand scattered, deep shadow contrast. Warm palette of sand, amber, sage and deep navy. Small letterspaced deep-navy serif capitals in the top left corner read WARBY PARKER. Clean serif text in the lower left reads Sunglasses from $95. Bright, breezy, editorial summer campaign, photorealistic.
04.1
Drift
Invented a full beach and ocean where the brief said a sandstone surface. Palm shadows, hat and green gradient lenses correct.
04.2
On brief
Held the sandstone surface exactly — no invented ocean. Palm-frond shadows and green gradient lenses correct. Closest read of this brief.
04.3
On brief
Sandstone, palm shadows, straw hat, green lenses all correct plus serif wordmark. Added a stripe to the linen.
04.4
Drift
Most dramatic light in the set, but shadows dominate and the product shrinks. Wordmark sans; copy largest and boldest of the five.
04.5
Drift
Sandstone and palm shadow correct. Copy collapsed to a single line at the smallest scale in the set.
Deliberate imperfection: can the model make something look un-produced?
Casual user-generated-content style photo, square format. Slightly imperfect handheld smartphone selfie of a young man in a bathroom mirror, wearing new navy rectangular acetate eyeglasses, half-smiling, one hand holding the phone. An open cardboard Home Try-On box holding five eyeglass frames sits on the counter beside a toothbrush cup. Mixed indoor lighting, mild phone-camera noise and slightly soft focus, a faint fingerprint smudge on the mirror. Authentic, unpolished, real-life feel, natural colors, no studio lighting. Small letterspaced deep-navy serif capitals in the lower left corner read WARBY PARKER. Photorealistic.
05.1
On brief
Convincingly un-produced. Try-On box reads “WARBY PARKER / Home Try-On” cleanly. Toothbrush cup and mirror smudge present.
05.2
Defect
Leaked my prompt's style words into the ad as copy — the image carries the line “Natural colors, unpolished.” Descriptor became headline. Box text otherwise clean.
05.3
On brief
Box carries “Good things come in five” — Warby Parker's real Home Try-On line, unprompted. Accurate, and an IP flag. Five frames present.
05.4
Drift
Box text clean, but the scene is too clean and saturated to read as UGC — it ignores the “unpolished, phone-camera” instruction.
05.5
Defect
Garbled text: the box reads “Home Try You!” instead of “Home Try-On”.
Architecture and environmental depth with signage or set dressing.
Premium eyewear advertisement, square format. Street-level exterior of an eyewear retail storefront on a sunny city corner: large plate-glass windows, deep navy painted facade, brass hardware, and letterspaced serif signage above the door reading WARBY PARKER. Neatly lit interior display shelves of eyeglasses visible through the glass, a blurred pedestrian walking past in motion blur, warm late-afternoon sunlight raking across the sidewalk with long shadows. Clean architectural composition, warm neutral palette of oat, greige and deep navy. Clean serif text in the lower left reads Premium eyewear, starting at $95. Editorial urban campaign photography, photorealistic.
06.1
On brief
Navy facade, gold serif signage, lit interior shelves, blurred pedestrian, long shadows — all present. Period added to copy.
06.2
On brief
Cleanest architecture of the set. Gold serif signage and motion-blurred passer-by correct.
06.3
On brief
Serif signage plus “NICE TO SEE YOU” interior graphic — real Warby Parker store signage, unprompted. Street sign and address rendered cleanly. Copy exact.
06.4
Drift
Signage rendered sans where the brief explicitly said letterspaced serif signage. Added autumn leaves.
06.5
Drift
Composition correct but signage is smallest and least legible of the five.
Royal blue, slab-serif, brick-orange, hard light on coloured tile. The hard brief: specific silhouettes, specific type, specific light. This is where models separated.
#1B2FBFCan the model hold a human face, real skin, and a product on-face without drifting?
Men's grooming advertisement, square format. Tight editorial crop of a man's face and jawline as he shaves with a matte black razor with a chrome five-blade cartridge and teal trim, a clean stripe cut through the white shave foam on his cheek. Real visible skin texture and stubble, calm focused expression, water droplets on his jaw. Hard directional daylight from the upper right, sage-green square ceramic tile wall behind him, chrome faucet edge in frame. Saturated color blocking of royal blue, sage green and warm white. A vivid royal-blue shave gel bottle with a bold white slab-serif HARRY'S wordmark sits on the ledge in the foreground. Confident, no-nonsense, tactile, photorealistic commercial photography, sharp detail.
01.1
Drift
Sage tile, teal-trim razor, foam stripe all correct. Bottle text clean. Wordmark sans, not slab-serif.
01.2
Drift
Tightest crop and cleanest chrome. Bottle text clean here. Wordmark sans.
01.3
On brief
Most secondary pack copy in the set — “Foaming Shave Gel / Lathers richly, to soothe & cushion / NET WT 4 OZ” — all legible and correct.
01.4
Defect
Wrong product silhouette: the shave gel became a squat flip-cap bottle reading as shampoo, not the briefed cylinder. Same failure as round one.
01.5
Drift
Sage tile and razor correct, but the bottle is again squat and rounded rather than the briefed cylinder.
A counting and arrangement test: exact item lists, precise grids, contact shadows.
Men's grooming advertisement, square format. Overhead flat-lay of a complete grooming kit arranged in a precise grid on a warm white square-tile surface: a matte black razor handle with a chrome five-blade cartridge and teal trim, a vivid royal-blue cylindrical shave gel bottle, a royal-blue face wash tube, a small blue travel blade cartridge case, and a black comb. Hard directional daylight from the upper right casting crisp parallel shadows, a few water droplets beading on the tile, grout lines forming a clean grid. Saturated color blocking of vivid royal blue against warm white and black. Bold white slab-serif wordmark HARRY'S on the blue bottle. Confident, orderly, tactile commercial product photography, sharp detail, photorealistic.
02.1
Defect
All five items correct and richly labelled, but the razor handle text is mirrored — “HARRY'S” renders reversed.
02.2
Defect
Worst text failure in the run. “SHAVE GEL” renders reversed and the face wash tube reads “FIRASE WASH / 183 YEHV OHARSE” — pure garble.
02.3
On brief
All five items correct with full, accurate pack copy on both the gel and the face wash. Zero text defects. Best asset in the run.
02.4
Drift
Text clean, but the gel is a squat flip-top and it added a second comb — object-count drift against an explicit five-item list.
02.5
Defect
Misspelled the brand: the face wash tube reads “HARY'S”, missing an R. Also swapped “FACE WASH” for “FACIAL WASH”.
Pure graphic layout. Typography instruction is the whole brief here.
Men's grooming advertisement, square format. Bold graphic promo layout on a flat vivid royal blue field. Centered large white slab-serif headline reads Start your Shave Trial. Below it, a matte black razor handle with a chrome five-blade cartridge and teal trim floats at a slight angle, lit with hard studio light and casting a crisp drop shadow onto the blue. A brick-orange rounded button near the bottom holds white uppercase text GET STARTED. Bold white slab-serif wordmark HARRY'S in the top left corner. Confident, no-nonsense, generous negative space, crisp typographic hierarchy, premium campaign design, photorealistic product rendering.
03.1
Drift
Clean layout and correct rust pill button, but headline and wordmark are sans where slab-serif was briefed.
03.2
Drift
Headline pushed to all caps sans — misses slab-serif and invents the caps treatment.
03.3
On brief
Only clean slab-serif in the brand — both wordmark and headline rendered as a proper chunky slab, exactly as briefed. This overturns round one's finding.
03.4
On brief
Also delivered a slab-ish serif wordmark and headline. Strongest Grok asset in the run — graphic layout suits it.
03.5
Drift
Headline is a transitional serif, not a slab; wordmark sans. Layout and button correct.
Hard light, cast shadows, and prop staging away from the brand's usual set.
Men's grooming advertisement, square format. Travel-ready still life of an open canvas dopp kit bag in warm tan, with a matte black razor handle with a chrome five-blade cartridge and teal trim, a small vivid royal-blue travel-size shave gel can, and a royal-blue face lotion tube spilling out onto a weathered wooden surface beside a passport and a set of keys. Hard warm morning sunlight from the upper right casting long crisp shadows. Saturated color blocking of royal blue against tan canvas and warm wood. Bold white slab-serif wordmark HARRY'S on the blue can. Rugged, practical, tactile commercial product photography, sharp detail, photorealistic.
04.1
On brief
Dopp kit, passport, keys, hard sun all correct. “TRAVEL SIZE 1.4 fl oz” and SPF-15 lotion copy legible.
04.2
Defect
Mirrored text again — the travel can's wordmark renders reversed. Also duplicated the passport.
04.3
On brief
Every label perfect: gel, “FACE LOTION / Broad Spectrum SPF 15”, razor mark, US passport. Cleanest execution of the concept.
04.4
On brief
Text clean, embossed “H” on the canvas, lotion squeezed out for realism. Bottle closer to spec than its other attempts.
04.5
Drift
Text clean here. Silver cap instead of the briefed blue, and the hard-sun instruction softened to indoor window light.
Deliberate imperfection: can the model make something look un-produced?
Casual user-generated-content style photo, square format. Slightly imperfect handheld smartphone shot looking down at a cluttered real bathroom counter: a matte black razor with a chrome five-blade cartridge and teal trim resting on a damp folded hand towel, a vivid royal-blue shave gel bottle with a bold white slab-serif HARRY'S wordmark, a crumpled cardboard shipping box, and a toothbrush in a cup. Overhead bathroom lighting with a mild phone-camera flash reflection, slight motion blur, water spots on the countertop. Authentic, unpolished, real-life feel, natural colors, no studio lighting. Photorealistic.
05.1
On brief
Genuinely un-produced feel. Bottle copy clean. Invents a real third-party toothpaste brand — minor IP flag.
05.2
Defect
Mirrored “HARRY'S” on the bottle, and it rendered a real Amazon logo on the box — unprompted third-party IP.
05.3
On brief
Full accurate pack copy plus mammoth mark, clean box branding, correct clutter. Best UGC asset in the run.
05.4
Defect
Mirrored box text — “HARRY'S” renders reversed on the flap. Bottle silhouette drifts squat again.
05.5
On brief
Text clean and bottle closer to a cylinder. Marble counter reads a touch styled for UGC.
Architecture and environmental depth with signage or set dressing.
Men's grooming advertisement, square format. Gym locker-room still life of an open navy duffel bag on a worn wooden bench, with a matte black razor handle with a chrome five-blade cartridge and teal trim, a vivid royal-blue shave gel bottle, and a rolled white towel spilling out. Rows of steel lockers in the background, hard overhead light raking down and casting crisp shadows on the bench slats, faint steam in the air. Saturated color blocking of vivid royal blue against steel gray and navy. Bold white slab-serif wordmark HARRY'S on the blue bottle. Confident, athletic, tactile commercial product photography, sharp detail, photorealistic.
06.1
On brief
Numbered lockers, steam, rolled towel, duffel all correct. “ALOE & CUCUMBER / 200ml” legible. Strong asset.
06.2
On brief
Text clean here. Bottle lying down rather than standing, but light shaft and steam are the best in the concept.
06.3
On brief
All labels perfect, plus a “WORK HARD” key fob invented on-brand. Zero defects.
06.4
Drift
Text clean, but the gel is squat-flip-cap again and it added a second razor against a single-razor brief.
06.5
On brief
Bottle back to a correct cylinder, text clean, steam and lockers correct.
Eight defects across sixty assets. Four belong to one model. Two are unprompted third-party logos, which is a legal problem rather than a quality one.
| Model | Where | What went wrong |
|---|---|---|
| Nano Banana Pro | Harry's flat-lay | “FIRASE WASH / 183 YEHV OHARSE” on the face wash tube; “SHAVE GEL” reversed |
| Nano Banana Pro | Harry's seasonal | Travel can wordmark rendered mirrored |
| Nano Banana Pro | Harry's UGC | “HARRY'S” mirrored on bottle; unprompted real Amazon logo on the box |
| Nano Banana Pro | Warby Parker UGC | Prompt style words leaked into the ad as copy: “Natural colors, unpolished.” |
| Dola Seedream 5.0 Pro | Warby Parker UGC | Box reads “Home Try You!” instead of “Home Try-On” |
| Dola Seedream 5.0 Pro | Harry's flat-lay | Brand misspelled “HARY'S” |
| Nano Banana 2 | Harry's flat-lay | Razor handle wordmark mirrored |
| Grok Imagine | Harry's UGC | Box flap text mirrored |
Twelve for twelve on text, honoured both serif and slab, held every product silhouette, and reproduced copy exactly without inventing punctuation. If the asset carries legible words, start here.
Fast, warm, dependable framing. One mirrored handle in twelve. Fine for concepting; proof any legible pack copy before it ships.
Best light and shadow in the run — and the worst text. Four failures in twelve, including prompt-leak and a real Amazon logo. Use it for scenes with no readable type, or composite type in afterwards.
Its best asset was the promo card, where it nailed the slab. But it drifted the Harry's bottle in four of six briefs and added objects nobody asked for. Never use it where the product silhouette is the point.
Airiest results, improved product fidelity versus round one. But it misspelled the brand and garbled a box line — same caution as Nano Banana Pro.
This is still not a benchmark. One sample per model per concept, no seed control. Six concepts caught what one couldn't, but a single seed can still flatter or sink any cell. The honest read: model tendencies now have real support — the text-defect counts, Grok's bottle drift replicating four times, GPT's serif behaviour holding across twelve. Precise ratios do not. Three to five seeds per cell scored blind is what would make these numbers load-bearing.
Neither brand is yours, and the models know them. GPT reproduced Warby Parker's real “Good things come in five” and in-store “NICE TO SEE YOU” unprompted; Nano Banana Pro rendered a real Amazon logo; Nano Banana 2 rendered a real toothpaste brand. Impressive recall, and precisely why these are an internal model evaluation — not assets any of these brands could run.
