Geometric Composition
Text-to-Image“A glass cube on a wooden table. Inside the cube is a small blue sphere. On top of the cube sits a red book. A green plant is behind the cube, partially visible through the glass. Soft window light from the left.”
AI Judge Analysis
FLUX.2 [flex]
- + Perfect prompt adherence for all spatial relationships.
- + Excellent lighting consistency with a soft window light effect from the left.
- + The blue sphere has a nice matte texture that contrasts well with the glass.
- − The glass cube has a slightly thick, plastic-like bezel at the bottom.
- − The composition is a bit centered and lacks the dynamic lighting seen in the competitor.
FLUX.2 [max]
- + High-quality material rendering, especially the leather texture of the book cover.
- + Beautiful lighting with realistic caustic reflections and sunbeams on the table.
- + The glass cube looks more like actual crystal or glass with thin edges.
- − The plant is barely visible through the cube's glass, feeling more like a background element than 'partially visible through' as requested.
- − The blue sphere is quite reflective, which may slightly obscure its solid color identity compared to Model A.
Verdict: Both models followed the prompt instructions very accurately. FLUX.2 [flex] had slightly better clarity regarding the plant being visible through the glass, while FLUX.2 [max] produced a more sophisticated image with superior textures and lighting effects. FLUX.2 [max] is the winner due to its photorealistic rendering of the book and the complex light interactions on the table.
Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
FLUX.2 [flex]
- + Excellent preservation of the car's design and details from the source image.
- + The man's likeness, hair, and clothing (specifically the plaid pattern) are clearly visible and accurate to the source.
- + Conveys a strong sense of motion with realistic motion blur on the road and wheels.
- − The man's hand on the steering wheel is slightly malformed and small.
- − The lighting on the man's face is a bit flat compared to the bright outdoor environment.
FLUX.2 [max]
- + Maintains the car's identity and the man's unique style very well.
- + The coastal background is sharp and well-integrated with the subject.
- + Good lighting and shadows that match the exterior environment.
- − The image depicts a static scene (parked or very slow) which contrasts with the prompt 'driving down the coastline'.
- − The man's facial expression is less natural and cheerful than the source image.
- − Minor warping on the windshield frame.
Verdict: Both models successfully combined the man and the car from the separate source images into a believable California coastal scene. FLUX.2 [flex] is the preferred choice because it successfully interprets the 'driving' aspect of the prompt by adding motion blur, and it better preserves the man's friendly expression and facial likeness. FLUX.2 [max] produces a high-quality image but it appears static, looking more like a parked car photoshoot than a man driving.
Candid Street Photography
Text-to-Image“A candid street photo of an elderly Japanese man repairing a red bicycle in light rain, reflections on wet pavement, shallow depth of field, 50mm lens, natural skin texture, imperfect framing, motion blur from passing cars, cinematic but realistic, no stylization.”
AI Judge Analysis
FLUX.2 [flex]
- + Excellent shallow depth of field with beautiful bokeh in the background.
- + Strong adherence to the 'imperfect framing' prompt with the large pole in the foreground.
- + Authentic skin textures and realistic rain effects on the clothing and pavement.
- − The bicycle geometry is slightly warped near the man's hands.
- − The motion blur of the cars is a bit static compared to the depth of field.
FLUX.2 [max]
- + Superior mechanical detail on the bicycle, including the chain guard and spokes.
- + Effective use of the 'motion blur' request with the passing silver car.
- + Natural, rugged skin texture on the hands and face.
- − The framing is a bit more conventional/centered despite the 'imperfect framing' request.
- − The man's kneeling posture looks a bit physically awkward/unbalanced.
Verdict: Both models followed the prompt exceptionally well, capturing the atmosphere of a rainy Japanese street. FLUX.2 [flex] excelled at the requested 'imperfect framing' and shallow depth of field, creating a more cinematic feeling, while FLUX.2 [max] provided better mechanical realism for the bicycle and superior motion blur on the background traffic.

FLUX.2 [max]
- + Better diorama construction with tiered layers and a wooden platform.
- + Integration of the flag icon within the text line is more stylistically cohesive.
- + Includes additional miniature details like chopsticks that enhance the scene.
- − The textures on the salmon (nigiri) look slightly more 'clay-like' and less refined than Model A.
- − The text is slightly smaller and has less visual impact than Model A.
Verdict: Both models followed the prompt exceptionally well, producing clean isometric dioramas with accurate text. FLUX.2 [flex] has superior texture work on the food and stronger typography, while FLUX.2 [max] provides a more complex and interesting diorama base with better graphic design integration for the flag.

Night Sky Transformation
Editing“Change the scene to night: a deep, dark sky with subtle, glistening stars visible behind the mountain.”
AI Judge Analysis
FLUX.2 [flex]
- + Excellent source preservation, keeping the town layout nearly identical to the original.
- + Creative addition of a moon glow behind the peak which adds atmospheric depth.
- + Successfully transitions the lighting on the mountain faces to a night-time palette.
- − The visible stars are very sparse and almost look like noise artifacts.
- − The river reflection remains quite bright, similar to the sunset version.
FLUX.2 [max]
- + Perfectly atmospheric night sky with more clearly defined, glistening stars.

Verdict: Both models performed exceptionally well at preserving the source image while changing the time of day. FLUX.2 [max] is the winner for its superior rendering of the 'glistening stars' requested in the prompt and for creating a more cohesive night atmosphere where the water body correctly reflects the village lights rather than the missing sun. FLUX.2 [flex] is also strong but has slightly less convincing star details.

- + Excellent full-body framing with clear view of the boots.
- + Natural and soft golden hour lighting on the subject's face.
- + Accurate hand-on-hip pose with well-rendered gloves.
- − The cape physics look a bit stiff, trailing off to the side without a clear anchor.
- − Background feels slightly generic compared to the specific New York buildings in the competitor.
FLUX.2 [max]
- + Dynamic and realistic cape physics with a dual-tone red and blue design.
- + Atmospheric background featuring recognizable New York architecture and city lights.
- + Superior suit texture and detailed chest emblem.
- − The 'full-body' requirement is slightly compromised as the bottom of the boots are cropped.
- − The lighting on the character's face is a bit flat compared to the bright sunset behind her.
Verdict: Both models followed the prompt exceptionally well, but FLUX.2 [max] produced a more cinematic and atmospheric image with better integration of the New York cityscape and superior suit textures.

Flat-vector style, crisp lines, consistent iconography, subtle gradients only. Steps (stop at landing): 1. Launch (Saturn Vicon) 2. Earth Orbit (Earth + orbit ring icon) 3. Translunar (trajectory arc icon) 4. Lunar Orbit (Moon + orbit ring icon) 5. Descent (lunar module descending icon) 6. Landing (lunar module on the surface icon) Small supporting elements (minimal text): • Crew strip: three silhouette icons with only last names: Armstrong, Aldrin, Collins. • Landing site marker: Moon pin labeled "Tranquility" only. Layout constraints: generous margins, large readable labels, clean background with subtle stars. Vector-only, print-poster look, high resolution.”
AI Judge Analysis
FLUX.2 [flex]
- + Sophisticated color palette that strictly adheres to the NASA-inspired request.
- + Excellent typography and spacing, creating a professional infographic look.
- + Highly detailed and accurate flat-vector icons for the Saturn V and Lunar Module.
