Head to head: DeepSeek Janus-Pro vs Fibo Bbq Preview

Fibo Bbq Preview takes this one decisively. On aggregate it posts a 61.2 to DeepSeek Janus-Pro’s 45.1, wins 7 of 8 tasks, and does it with 98% confidence. That is not a vibes-based edge or a judge-splitting squeaker; it’s a clear, statistically solid result.

The pattern is straightforward: Fibo is the more reliable prompt follower when the image has to hold up under scrutiny. It was better on reflective materials and optical behavior in Reflections & glass and Smartwatch shopwindow refractions, where Janus-Pro often looked atmospheric but broke the actual physics or missed key prompt elements. It also crushed the more technical prompts: in Macro lens on soldered board, Janus-Pro wandered into something closer to a keyboard glamour shot, while Fibo actually delivered a believable PCB macro with the right product-photo framing.

Fibo also had the stronger action and design discipline. In Courier leap over data canal, it captured the mid-air motion, readable route tablet, and anime-cyberpunk energy the prompt asked for; Janus-Pro had the setting, but not the movement. In Golden hour repair kiosk, Fibo included the kiosk, technician, drone, battery cases, and awning that made the scene specific rather than merely warm-toned. Even on the notoriously ugly Legible multi-line text task, neither model was good, but Fibo was at least closer to a usable minimalist poster while Janus-Pro fell into severe text corruption.

DeepSeek Janus-Pro’s lone win, Perspective & scale, is real and deserved. It produced the better one-point-perspective library aisle, kept the aisle empty, and looked more photorealistic. That result also says something important about Janus-Pro: it can compose a clean image when the brief is mostly about spatial structure rather than dense object-level requirements. But that strength didn’t travel. On exacting prompts, it repeatedly traded fidelity for mood, and in this test mood was not enough.

Final call: Fibo Bbq Preview is the better image model here, and by a comfortable margin. Janus-Pro shows occasional aesthetic instincts, but Fibo is the one you’d trust to actually execute the assignment.

How they were tested

We ran 8 fresh image tasks, generated on the fly for this matchup so neither model could prepare in advance, and had gpt-5.4 score each one. To cancel position bias, every task was judged twice — once in each presentation order — and every number reported here, including the headline totals, is the average of both passes. DeepSeek Janus-Pro scored 45.0 to Fibo Bbq Preview's 61.2.

1. Reflections & glass

A photorealistic close-up of a chrome teapot on a polished dark marble counter next to a glass of water; the window and a red apple on the counter must be correctly reflected in BOTH the chrome and the water's surface, dramatic side light, 16:9.

Winner: Fibo Bbq Preview — Model B adheres more closely to the prompt with a clearer chrome teapot, polished dark marble counter, dramatic side light, and more convincing window reflection on the metal, while Model A has a moodier composition but incorrectly places the apple reflection inside the teapot and gives weaker evidence of the required reflections in the water. Model A is aesthetically strong, but Model B is more technically coherent and prompt-faithful overall. (Second judge pass, order swapped — scores are the average of both: Model B adheres more closely to the prompt with a clear close-up, polished dark marble, dramatic side light, and convincing reflections of both the window and apple in the chrome teapot; its composition is also cleaner and more photorealistic. Model A has appealing mood and reflections, but the teapot shape is less like a chrome teapot, the glass reflection behavior is less clearly correct, and the overall image feels less precise and polished.)

2. Courier leap over data canal

A cyberpunk bicycle courier in a teal rain shell vaults mid-air over a narrow canal lined with glowing server racks, one hand clutching a ruggedized tablet showing a flickering route map to Sector 7C, loose charging cables and droplets trailing behind to emphasize motion, front wheel turned sharply, coat hem snapping in the wind, dynamic diagonal composition, anime-inspired digital illustration with crisp linework and kinetic energy, cool dusk city palette with magenta signage and cyan rim light, 16:9

Winner: Fibo Bbq Preview — Model B matches the prompt more closely with a clear mid-air vault, teal rain shell, ruggedized tablet showing a route map, trailing cables and droplets, and stronger anime-inspired kinetic energy. Model A has a nice cyberpunk canal setting and server racks, but it misses key details like the tablet/map readability, sharper action cues, and the specified dynamic diagonal composition. (Second judge pass, order swapped — scores are the average of both: Model B better matches the prompt’s anime-inspired kinetic feel, with a strong mid-air vault, teal rain shell, glowing server-rack canal, and vivid magenta/cyan cyberpunk palette; its tablet also reads more clearly as a route device. Model A captures the canal and server racks well, but the action feels less dynamic, the courier styling is less faithful, and the overall image is less crisp and energetic.)

3. Macro lens on soldered board

An extreme macro close-up of a custom mechanical keyboard PCB labeled "Aster-9", a fine-tipped soldering iron touching a single molten joint beside tiny lavender capacitors and a handwritten calibration sticker reading 03B, razor-thin depth of field with creamy bokeh swallowing the background, highly detailed product photography, precise side lighting revealing metallic texture and flux sheen, cinematic framing through a 100mm macro lens

Winner: Fibo Bbq Preview — Model B matches the prompt far more closely with a true PCB macro, visible lavender components, a fine-tipped soldering iron contacting a single joint, and clearer product-photography styling; although the text is imperfect and the handwritten calibration sticker is not convincingly rendered, it still substantially outperforms Model A. Model A looks more like a stylized keyboard corner than an extreme PCB macro and misses key prompt elements such as the Aster-9 labeling, lavender capacitors, and realistic soldered-board detail. (Second judge pass, order swapped — scores are the average of both: Model B matches the prompt far more closely with a true PCB macro shot, visible lavender components, a soldering iron contacting a molten-looking joint, and legible near-correct board text; although the calibration sticker text is incomplete and the joint is somewhat stylized, the overall composition and product-photography look are strong. Model A depicts keyboard keycaps rather than a PCB, misses the specified labeling and sticker details, and does not convincingly render the requested macro electronics scene.)

4. Perspective & scale

A photorealistic one-point-perspective shot down a long empty library aisle, shelves receding to a single vanishing point, books getting consistently smaller with distance and nothing warped or wrongly sized, warm overhead light, 16:9.

Winner: DeepSeek Janus-Pro — Model A better matches the requested photorealistic one-point-perspective view down an empty library aisle, with convincing scale reduction and a clean central vanishing point. Model B has strong symmetry and warm lighting, but the foreground stool violates the empty-aisle prompt and the image feels more stylized than photorealistic. (Second judge pass, order swapped — scores are the average of both: Model A better matches the requested photorealistic one-point-perspective library aisle, with convincing scale recession, an empty aisle, and warm overhead lighting in a widescreen frame. Model B has strong symmetry and appealing warmth, but the foreground step stool breaks the 'empty' aisle requirement and the image feels more stylized than photorealistic.)

5. Smartwatch shopwindow refractions

Inside a narrow watchmaker’s studio on Kestrel Lane, a transparent smartwatch prototype hovers on a glass stand near a rain-speckled shopwindow, surrounded by chrome tools, smoked mirrors, and a half-full tumbler of mineral water, the scene requiring precise layered reflections and refractions: street tram lights doubled in the window, bent clockface numerals through the curved glass, subtle mirror echoes of the artisan’s hands, hyperreal editorial product photography style, moody neon night lighting in cobalt and amber, 16:9

Winner: Fibo Bbq Preview — Model B adheres much more closely to the prompt with a transparent smartwatch prototype, rain-speckled window, chrome tools, mineral water, and strong cobalt/amber refraction effects; Model A is atmospheric but reads more like a traditional watch display and misses the transparent prototype and layered optical complexity. Model B also has cleaner editorial product focus and more convincing neon-night reflections, though both images are visually appealing. (Second judge pass, order swapped — scores are the average of both: Model B matches the prompt more closely with a transparent smartwatch prototype, rain-speckled window, chrome tools, mineral water, and strong layered reflections/refractions in cobalt and amber lighting; its only major miss is the setting reading more like a transit interior than a narrow watchmaker’s studio. Model A has a more workshop-like mood, but it lacks the transparent hovering prototype feel, the specified refraction complexity, and the editorial product-photography clarity, with a muddier composition and weaker focal emphasis.)

6. Legible multi-line text

A minimalist event poster with three lines of crisp, correctly-spelled text stacked and centered: 'NIGHT MARKET' large on top, 'Fridays · 6–11pm' in the middle, 'Riverside Pier 4' at the bottom, on a deep navy background, clean sans-serif, subtle grain.

Winner: Fibo Bbq Preview — Model B is closer to the requested minimalist poster style, with a cleaner centered layout, deep navy background, and stronger overall polish, even though the text is still badly misspelled and split incorrectly. Model A follows the stacked-poster idea but has severe text corruption, duplicated lines, and a much messier composition that hurts both adherence and readability. (Second judge pass, order swapped — scores are the average of both: Model B is much closer to the requested minimalist poster, with centered stacked text on a deep navy background and a cleaner sans-serif look, though several lines are misspelled and malformed. Model A has severe text corruption, duplicated extra lines, and weaker composition, so it adheres far less to the prompt despite using a similar color palette.)

7. Golden hour repair kiosk

A compact solar gadget repair kiosk on the salt flats outside Arroyo Nueve at golden hour, a technician in copper overalls recalibrating a foldable drone beside stacked translucent battery cases, long amber shadows stretching across the crusted ground, low sun flaring through a hand-painted fabric awning, dust glowing in the warm light, mood of calm ingenuity, rendered as a vintage travel poster with simplified shapes, rich grain, and elegant typography space, 16:9

Winner: Fibo Bbq Preview — Model B matches the prompt more completely with a clear compact repair kiosk, technician in copper overalls recalibrating a foldable drone, stacked translucent battery cases, and a fabric awning lit by golden-hour sun; Model A captures the warm salt-flat mood well but lacks a convincing kiosk and vintage travel-poster treatment. Model B also has stronger subject clarity and more balanced composition, though neither image fully delivers the simplified-shape poster aesthetic or typography space. (Second judge pass, order swapped — scores are the average of both: Model B matches the prompt more completely, showing a compact repair kiosk, technician in copper overalls, foldable drone, translucent battery cases, and strong golden-hour lighting with long shadows; it misses the vintage travel poster simplification and typography space somewhat. Model A captures the salt flats and warm light mood, but omits the kiosk structure and awning details, feels less like a repair scene, and is less aligned with the specified poster-like composition.)

8. Exact counting

A clean overhead flat lay on white marble of EXACTLY seven identical espresso cups arranged in a single straight row, each clearly separate and individually countable, even soft lighting, 16:9.

Winner: Fibo Bbq Preview — Model A fails the core counting and arrangement requirements, showing eight cups and not a single straight row. Model B is cleaner and arranged in a straight row on marble, but it still misses the prompt by showing only six cups and appearing to depict empty cups rather than espresso. (Second judge pass, order swapped — scores are the average of both: Model B has a cleaner flat-lay composition on marble, but it fails the exact-count requirement with only six cups instead of seven. Model A gets the count right with seven cups, but it misses the single straight row requirement and is less aligned with the specified marble flat-lay composition.)
