a donut chart with three segments labelled 60% Local, 30% Cloud, 10% API, legend on the right, the title "Where inference runs" above, flat design, light grey background
rewritten prompt sent to every model (144 words, aspect 4:3)
A flat design data visualization featuring a donut chart centered on a light grey background. The chart consists of three distinct segments: a large segment occupying sixty percent of the ring, a medium segment occupying thirty percent, and a small segment occupying ten percent. The segments are rendered in solid, contrasting colors typical of modern dashboard aesthetics. To the right of the donut, a vertical legend lists the categories with corresponding color swatches. The text "60% Local" is written next to the first swatch, "30% Cloud" next to the second, and "10% API" next to the third, all in a clean sans-serif font. Above the chart, the title "Where inference runs" is written in a bold, dark grey sans-serif typeface. The composition is balanced and minimal, with no shadows or gradients, emphasizing clarity and readability. The image contains no other lettering or decorative elements.
- The color palette is extremely low-contrast, making the 30% and 10% segments nearly indistinguishable from the 60% segment in the chart itself.
- The legend swatches for 'Local' and 'Cloud' appear to be the same dark grey, failing to visually differentiate the categories as intended.
- The donut chart has five visible segments instead of the requested three.
- The segment proportions do not match the 60/30/10 percentages stated in the legend.
- The 10% API segment is the same blue as the 60% Local segment, making it visually indistinguishable from the larger segment.
- The legend uses the same blue dot for both '60% Local' and '10% API', which is confusing and fails to differentiate the two categories.
a horizontal flowchart with five rounded boxes labelled Request, Check, Approve, Sign, Archive, connected by arrows, a diamond decision node after Check with branches Yes and No, blue outlines on white
rewritten prompt sent to every model (170 words, aspect 16:9)
A horizontal flowchart diagram rendered in a clean, minimalist vector style on a pure white background. Five rounded rectangular boxes are arranged in a linear sequence from left to right, each featuring a thin blue outline and a white fill. The first box contains the text "Request" in a simple black sans-serif font. An arrow points right to the second box, labelled "Check". Following this, a diamond-shaped decision node with a blue outline appears, connected by an arrow from the Check box. The diamond branches into two paths: an upper arrow labelled "Yes" and a lower arrow labelled "No". The Yes path leads to the third rounded box, labelled "Approve", which connects via an arrow to the fourth box, labelled "Sign", and finally to the fifth box, labelled "Archive". The No path loops back or terminates, maintaining the blue outline aesthetic. All text is black, legible, and centered within its respective shape. The image contains no other lettering or decorative elements, focusing entirely on the structural logic of the process.
- The 'No' branch from the decision diamond bypasses the 'Sign' step, which may be logically inconsistent for a standard approval flow.
- The loop-back arrow from 'Approve' to the decision diamond is visually cluttered and could be misinterpreted as a re-check rather than a re-approval.
an exploded-view technical schematic of a wireless earbud with four labelled parts: shell, battery, driver, antenna, thin leader lines to each label, isometric view, white background, engineering drawing style
rewritten prompt sent to every model (208 words, aspect 1:1)
An isometric exploded-view technical schematic of a single wireless earbud, rendered in a precise engineering drawing style on a pure white background. The device is disassembled into four distinct components, floating in a vertical stack with clear separation. The top component is the smooth, matte white outer shell, shaped like a teardrop. Below it hovers the compact, rectangular lithium-ion battery, depicted in a light grey tone. The third layer is the circular acoustic driver, showing its metallic diaphragm and copper voice coil. The bottom element is the thin, flexible antenna, coiled in a spiral shape. Thin, black leader lines extend from each component to specific labels. The text "shell" is written next to the top part, in a clean, sans-serif font. The text "battery" is written next to the second part, in a clean, sans-serif font. The text "driver" is written next to the third part, in a clean, sans-serif font. The text "antenna" is written next to the bottom part, in a clean, sans-serif font. The lighting is flat and even, eliminating shadows to emphasize the technical clarity. The lines are sharp and uniform, typical of CAD software output. The overall mood is clinical, precise, and informative, focusing entirely on the internal architecture of the audio device.
- The antenna is depicted as a flat spiral wire rather than a typical PCB trace or coil, which is a slight simplification.
- The driver component shows a copper coil that is more characteristic of a speaker voice coil than a typical earbud driver assembly, though acceptable for a schematic.
- The exploded view is slightly ambiguous as it appears to show a charging case shell rather than a single earbud shell.
- The antenna is depicted as a coiled wire with a long tail, which is less typical for a modern earbud schematic than a printed circuit trace.

a key visual for a digital advertising campaign of the company whose wordmark is image 1, using exactly the colour palette of image 2: the wordmark large and unchanged in the upper third, below it a stylised glowing neural network made of thin red lines and gold nodes on a near-black background, 16:9
rewritten prompt
A digital advertising key visual in a 16:9 landscape format. The background is a deep, near-black color with a subtle dark red radial glow in the center. In the upper third of the composition, the wordmark from image 1 is placed large and unchanged, preserving its exact typography, white and red coloring, and the tagline below it. In the lower two-thirds, a stylized neural network is depicted. This network consists of thin, glowing red lines connecting small, bright gold nodes. The network structure is abstract and organic, spreading across the dark space. The entire image strictly uses the color palette from image 2, utilizing the near-black background, the specific reds for the lines and wordmark accents, and the gold for the nodes and text details.
an empty white billboard on a modern city street at dusk, wet asphalt reflecting the lights, photographed from the pavement
rewritten prompt
A large, blank white billboard stands prominently on a modern city street corner during the blue hour of dusk. The smooth, matte surface of the sign is completely empty, devoid of any graphics or lettering. Below, the wet asphalt pavement glistens with rain, creating a mirror-like surface that reflects the warm amber glow of streetlamps and the cool blue tones of the fading sky. The viewpoint is low, positioned directly on the pavement, looking slightly upward toward the billboard, which dominates the upper frame. In the background, blurred silhouettes of contemporary glass skyscrapers rise against the twilight sky, their windows twinkling with interior lights. The scene is bathed in soft, diffused ambient light, with sharp specular highlights on the wet ground. The color palette features deep indigos, slate grays, and vibrant orange reflections. The image is a high-resolution photograph with a shallow depth of field, keeping the billboard in sharp focus while the distant cityscape remains softly out of focus, evoking a quiet, urban atmosphere.
- The reflection of the billboard on the wet pavement is slightly distorted and lacks sharpness.
- The base of the billboard pole appears to merge slightly with the ground texture.
put the wordmark of image 2 onto the empty billboard of image 1, filling the billboard with a near-black background and the wordmark centred, keeping the street, the lighting and the reflections exactly as they are
rewritten prompt
Place the wordmark from image 2 onto the empty white billboard in image 1. The billboard surface is filled with a near-black background, and the wordmark is centered on it. The wordmark consists of the text "YEAR2066.ai" in a bold sans-serif font, with "YEAR" and ".ai" in white and "2066" in red, positioned above the text "AHEAD OF ITS TIME" in smaller, gold, spaced-out capital letters. The surrounding environment remains exactly as in image 1: the wet street with its golden reflections, the city skyline in the background, the streetlights, and the overall lighting and composition are preserved without any changes.
- The perspective of the wordmark is slightly flattened relative to the billboard's angle, making it look like a decal rather than part of the screen.
- The reflection of the billboard on the wet street is not visible, which breaks the physical consistency of the scene.
print the wordmark of image 2 in vivid red on the white ceramic mug in image 1, correctly wrapped around the curved surface, everything else unchanged
rewritten prompt
The white ceramic mug in image 1 is the only element that changes. The wordmark of image 2 is printed on the visible side of the mug in vivid red, following the curvature of the ceramic surface so the lettering wraps naturally around the cylinder. The wordmark is copied exactly from image 2, including its lettering style, the red accent on the digits, and the smaller tagline beneath it. Everything else in image 1 stays exactly as in the source: the black over-ear headphones, the dark wooden table, the soft directional lighting, the shadows, the background wall, the composition, the camera angle, and the overall colour palette.
a campaign photo for the company whose wordmark is image 1: a diverse team of four people in a modern office looking at a large wall screen that shows the wordmark of image 1 with near-black background, vivid red accents, a gold highlight and warm white text, bold geometric sans-serif typography; the wordmark also appears small in the top-left corner of the picture; palette as in image 2
rewritten prompt
A campaign photograph of a diverse team of four people standing in a modern office, looking at a large wall screen. The screen displays the wordmark of image 1 against a near-black background, featuring vivid red accents, a gold highlight, and warm white text in bold geometric sans-serif typography. The wordmark of image 1 also appears small in the top-left corner of the picture. The scene uses the color palette from image 2, with a dark background, warm white text, and red and gold accents. The lighting is professional and even, highlighting the faces of the team members and the screen. The composition is balanced, with the team positioned in the foreground and the screen dominating the background.
a campaign photo for the company whose wordmark is image 1: a close-up of a laptop on a desk showing a dark dashboard with red and gold charts and the wordmark of image 1 in its header, near-black background, vivid red accents, a gold highlight and warm white text, bold geometric sans-serif typography; palette as in image 2
rewritten prompt
A close-up campaign photograph of a laptop resting on a dark desk, its screen displaying a dark analytics dashboard. The dashboard header features the wordmark of image 1, rendered in bold geometric sans-serif typography with the red and gold color treatment visible in that image. The dashboard interface includes vivid red charts, gold highlight bars, and warm white text labels, all set against a near-black background. The surrounding environment is dimly lit, emphasizing the glow of the screen. The color palette strictly follows the swatches in image 2, utilizing the deep black background, warm white text, vivid red, soft red, deep red, gold, muted beige, and dim brown tones. The composition is a tight, angled shot focusing on the laptop screen, with shallow depth of field blurring the desk surface slightly.
a campaign photo for the company whose wordmark is image 1: two business people shaking hands in front of a dark glass wall that carries the wordmark of image 1 in warm white, a red light strip along the floor, near-black background, vivid red accents, a gold highlight and warm white text, bold geometric sans-serif typography; palette as in image 2
rewritten prompt
A wide campaign photograph of two business people shaking hands in the center of the frame. They stand in front of a dark glass wall that displays the wordmark of image 1 in warm white. A red light strip runs along the floor, and the background is near-black. The scene uses the color palette from image 2, featuring vivid red accents, a gold highlight, and warm white text. The overall aesthetic is defined by bold geometric sans-serif typography and a modern, professional atmosphere.
a minimalist advertising poster, near-black background, vivid red accents, a gold highlight and warm white text, bold geometric sans-serif typography, the headline "AHEAD OF ITS TIME" in huge white letters in the centre and the text "YEAR2066.ai" in red below it, nothing else, 3:4
rewritten prompt
A minimalist advertising poster features a near-black background that absorbs light, creating a deep, void-like atmosphere. Vivid red accents appear as thin, sharp geometric lines framing the composition, while a single gold highlight adds a subtle metallic sheen to the lower right corner. The headline "AHEAD OF ITS TIME" is written in the centre in huge, bold, warm white letters using a geometric sans-serif typeface. Below the headline, the text "YEAR2066.ai" is written in vivid red, maintaining the same bold geometric style but at a smaller scale. The layout is strictly centered with ample negative space, emphasizing the stark contrast between the dark background and the bright typography. The lighting is flat and even, ensuring the text remains the sole focal point without shadows or gradients. The overall mood is futuristic, clean, and authoritative, relying on the interplay of black, white, red, and gold to create a striking visual impact. The image contains no other objects, figures, or decorative elements, focusing entirely on the typographic design.
an abstract hero image for a technology website using only the colours shown in image 1 (near-black background, the reds, the gold and the warm white), flowing light trails and soft glows, 16:9, no text
rewritten prompt
Create an abstract hero image for a technology website in a wide 16:9 frame, using only the colours from image 1: the near-black background #050304, the warm white #fffaf3, the bright red #ff3e3e, the soft red #ff6b6b, the deep red #8b1118, the gold #f7c86a, and the muted warm tones #cfc0b4 and #8d7a70. The scene shows flowing light trails and soft glows drifting across the dark field, with red and gold streaks curving like luminous ribbons, gentle halos of warm white and soft red blooming in the background, and subtle deep-red shadows anchoring the composition. The trails vary in thickness and opacity, some sharp and bright, others diffused into misty glows, creating a sense of motion and depth. No text, no letters, no symbols, no recognizable objects, no people, no logos. The overall mood is sleek, modern, and energetic, suitable as a full-width banner for a technology website.
- The vertical color bands in the background are somewhat blocky and lack the soft, diffused quality of a true glow.
- The light trails on the right side feel slightly disconnected from the central vertical elements, creating a minor compositional split.
Follow-up: fewer condition images, more working area
Two of the seven wordmark reproductions above lost a digit; both runs carried two condition images (wordmark plus palette sheet, or source photo plus wordmark), which halves the working area per image (side / √2).

5 · Editing: Qwen-Image-2.1 as editor vs Qwen-Image-Edit-2511
One generated source, six typical PIC STUDIO edits. Qwen-Image-2.1 receives the rewritten natural-language instruction (EDIT mode, editor QWEN-2.1). The 2511 editor receives the same rewritten instruction for plain edits and its tab-native adapter prompts for ADD, REMOVE and ANGLE (the way PIC STUDIO drives it). The judge rates whether exactly the instructed change was made and nothing else.
- The wooden mooring post appears to be a floating stump rather than a fixed structure, lacking a visible base or connection to the pier.
- The texture on the top of the mooring post is slightly smeared and lacks the sharp definition of weathered wood.

replace the background of image 1 with a stormy sea under dark clouds and big waves, keeping the fisherman exactly as he is
rewritten instruction
Replace the background of image 1 with a stormy sea under dark clouds and big waves. The fisherman in image 1 stays exactly as he is: his identity, face, white beard, green knit beanie, yellow raincoat, grey sweater, hands resting on the weathered wooden post, his pose, proportions, and the wooden pier in the foreground all remain unchanged. The new background shows a turbulent ocean with large crashing waves, a heavy dark overcast sky, and a moody, dramatic atmosphere. The lighting on the fisherman is preserved as in the source image, and the overall composition, framing, and camera viewpoint follow image 1.
- The lighting on the fisherman's face and jacket is slightly too bright and even for the dark, overcast sky behind him.
- The transition between the wooden pier and the water on the left is a bit soft and lacks sharp detail.
- The lighting on the fisherman's face and jacket appears slightly too bright and even for the dark, overcast sky behind him.
- The transition between the fisherman's yellow coat and the background waves is sharp, suggesting a potential composite edge.
add a white seagull sitting on the wooden mooring post in image 1, matching the light
rewritten instruction
In image 1, a white seagull sits calmly on top of the weathered wooden mooring post in the lower right foreground, positioned just beside the man's resting hand. The seagull faces slightly toward the left, its feathers rendered in clean white with soft grey shading on the wings, matching the overcast, diffused lighting of the scene. Its posture is relaxed and natural, as if it has settled there for a moment. Every other element of image 1 remains exactly as in the source: the elderly man with his white beard, green beanie, and yellow raincoat, his pose and expression, the wooden pier extending to the left, the fishing boats moored in the background, the grey cloudy sky, the water, and the overall composition, proportions, colours, and photographic style.
2511 prompt (tab-native adapter prompt): Add the white seagull sitting on the wooden mooring post to the image while preserving the background lighting and surrounding elements maintaining realism and original details
remove the three fishing boats from image 1 and fill the harbour with calm water
rewritten instruction
Edit image 1 by removing the three fishing boats moored in the background on the left side of the harbour, including their masts, rigging and hulls, and fill the area they occupied with calm, flat harbour water that matches the existing water surface in tone, colour and texture. The water extends smoothly to the horizon under the overcast sky, with no boats, masts or reflections of vessels remaining in that section. Everything else in image 1 stays exactly as in the source: the elderly bearded man in the yellow raincoat and dark knit hat, his pose with both hands resting on the weathered wooden post, the wooden pier in the foreground, the remaining boat on the right, the cloudy sky, the lighting, the colours, the composition, the proportions and the photographic style are all preserved unchanged.
2511 prompt (tab-native adapter prompt): Remove the three fishing boats in the harbour from the image while preserving the background and remaining elements maintaining realism and original details
change the fisherman's sweater in image 1 to red and his cap to dark blue, everything else unchanged
rewritten instruction
In image 1, change the colour of the fisherman's knitted beanie cap from dark green to dark blue, and change the colour of the sweater visible at his neckline from grey to red. Keep the man's face, white beard, yellow raincoat, pose, hands on the wooden post, the harbour, the fishing boats, the pier, the water, the overcast sky, the lighting, the composition, the proportions and every other element exactly as in image 1.
turn image 1 into an impressionist oil painting with visible brush strokes, keeping the composition
rewritten instruction
Transform image 1 into an impressionist oil painting with visible, textured brush strokes throughout the entire frame. The old bearded man in the yellow raincoat and green beanie, the weathered wooden pier, the moored fishing boats, the grey water, and the overcast sky are all rendered in loose, painterly strokes of color rather than photographic detail. The composition, framing, and placement of every element remain exactly as in image 1: the man stands center-right leaning on the wooden post, the pier extends to the left, and the boats sit in the background under a cloudy sky. The lighting, color palette, and proportions are preserved from the source, now expressed through the characteristic dabs and directional strokes of an impressionist oil medium.
- The brush strokes on the man's face are slightly less distinct than the rest of the image, creating a minor texture inconsistency.
- The hands resting on the wooden post appear slightly stiff and lack the fluidity of the surrounding painterly style.
- The brush strokes on the man's face are slightly too smooth, lacking the distinct impasto texture seen on the jacket.
- The wooden post in the foreground has a somewhat smeared and indistinct texture that blends oddly with the hand resting on it.
re-render image 1 from a right side view at eye level, medium shot, keeping the fisherman, his clothing and the pier
rewritten instruction
Re-render image 1 as a medium shot taken from a right side view at eye level. The fisherman stands on the wooden pier, his body turned so the camera captures his right profile. He keeps his exact identity, face, white beard, and proportions. He wears the same dark green knit beanie, grey sweater, and bright yellow raincoat. His hands rest on the weathered wooden post in the foreground. The background shows the same harbour scene with the row of moored fishing boats, the calm water, and the overcast grey sky. The lighting, colours, and photographic style remain identical to the source image.

Regenerated after the seam fix; requests are German on purpose so the rewriter's translation is part of the demonstration.
Aspect request: bergsee bei sonnenaufgang mit holzsteg
rewritten prompt
A serene mountain lake named Bergsee sits in a high alpine valley during the early moments of sunrise. A rustic wooden boardwalk, constructed from weathered grey planks, extends from the foreground shoreline directly into the calm, mirror-like water. The surface of the lake reflects the soft pastel hues of the sky, blending pale pinks, warm oranges, and gentle lavenders. Surrounding the water, steep slopes covered in dense evergreen forests rise sharply, their dark green silhouettes contrasting with the brightening horizon. The first rays of the sun peek over the distant peaks, casting long, ethereal shadows across the water and illuminating the mist that hovers just above the surface. The lighting is soft and diffused, creating a tranquil and peaceful atmosphere. The camera captures the scene from a low angle near the water's edge, using a wide-angle lens to encompass the expansive landscape. The image is a high-resolution digital photograph with sharp details on the wood grain and smooth gradients in the sky, evoking a sense of quiet natural beauty. The image contains no lettering.

7 · Method & settings
- Servers (own test instances on GPU 1, spawned through BACKEND_SERVER's real spawn path): Qwen-Image-2.1 bf16 DiT + int8 text encoder + RGBA VAE (port 5111), Z-Image-Turbo bf16 (5112), Qwen-Image-2512 Lightning Nunchaku FP4 (5113), Qwen-Image-Edit-2511 GGUF Q4_K_M with the angles/remover/adder adapters (5114).
- Prompts: every request is rewritten once by the vision LLM through PIC STUDIO's production rewriter (the same code path as Ctrl+W); the identical rewritten text is rendered by every model. Predecessors render at their native area with the same aspect ratio. Seed 3407 everywhere, one image per prompt (no cherry-picking).
- Judge: t2i rubrics on the vision LLM
vision-38-27b-obliterated(vLLM, GPU 0, temperature 0, thinking off); images are sent as JPEG copies at ≤1280 px (pixel budget of the backend). Pairwise verdicts use one stitched A|B picture and are asked in both orders. Rubric scores are LLM claims: the author spot-checked every set visually; the checklist verdicts of the format set were confirmed against the field values by eye for both sets. - Defaults changed by this round (all in TUI/CORTEX_CONFIG.txt, read at server load or per run): VAE decode tiles 1024/768 with encode tiles 256/192 and a loud decode fallback; CFG 3.0 with the negative prompt for text-to-image, 1.0 for image-conditioned runs (PIC_STUDIO_QI21_EDIT_CFG; 3.0 halves a 1536² edit); rewriting keeps the schema fields (PIC_STUDIO_REWRITE_KEEP_FIELDS=1); default schema pairs; the negative prompt without text/logo terms; plain results saved as RGB (PIC_STUDIO_QI21_ALPHA_MIN). Verified through the real TUI in a tmux session against the test server (field prompt, rewrite on: sent prompt ends with the field pairs, sidecar marks kept_fields, 2528×1696 at cfg 3.0 in 167 s) and through the tab's edit client (1536² edit at cfg 1.0 in 49 s).
