Following the release of Google Gemini 3’s image model, Nano Banana Pro, which has received widespread acclaim for its impressive capabilities, another highly anticipated AI image generator has entered the scene. On November 25, 2025, Black Forest Labs launched their next-generation model, Flux.2(includes Flux.2 Pro & Flux.2 Flex), earning praise from the AI community for its advanced performance.
As one of the leading AI tool aggregation platforms, AIPURE is committed to providing users with the latest AI news, comprehensive tool reviews, and practical guides. In this article, we put these two acclaimed AI image generators to the test using some of the most popular prompts trending among AI users, helping you determine which model best suits your creative workflow.
To give creators a clear, visual, and objective comparison between Flux.2 and Nano Banana Pro, the AIPURE team conducted a series of controlled tests using lmarena.ai’s "Slide-by-Slide" mode.
This setup allowed us to compare gemini-3-pro-image-preview (Nano Banana Pro) vs Flux-2-pro under identical prompts and identical conditions — ensuring fairness, consistency, and repeatability.
⚠️For this comparison article, all benchmark tests and evaluations are conducted using Flux.2 Pro.
Below are the comparison prompts and analysis across multiple creative categories.
────────────ˏˋ ★FLUX.2 Pro vs Nano Banana Pro★ ˎˊ──────────
Comparison 1: Infographic / Educational Illustration
💡 Prompt
🎯 Purpose
Tests:
- clarity of structured visual information
- scientific / educational illustration ability
- consistency across multiple panels
- label and detail rendering (even without explicit text)

Comparison 2: Poster & Logo Design
💡 Prompt
The logo should resemble a calligraphic mark incorporating subtle AI-related elements such as data waves, pixel grids, or abstract AI-chip silhouettes.
Use a simple two-tone palette: light-blue background with a dark-blue emblem, delivering both retro warmth and modern tech appeal. The final output should be iconic, memorable, and representative of AIPURE’s role as a hub of diverse AI tools.
🎯 Purpose
Tests:
- stylized design
- symbolic structure
- shape recognition
- brandability
- color discipline and contrast control

Comparison 3: Manga / Chibi Cartoon Creation
💡 Prompt
Include 3–4 panels featuring exaggerated expressions and comedic poses.
The tone should be warm and light, inspired by Studio Ghibli’s soft color palettes.
Use clean black-and-white line art with minimal accent colors.
Dialogue bubbles must be clear, readable, and well-placed.
Output as a high-resolution PNG, 16:9 or 1:1.
🎯 Purpose
Tests:
- stylistic accuracy (chibi / manga)
- panel layout and storytelling
- character consistency across frames
- bubble + scene composition

Comparison 4: Photorealistic Portrait Lighting
💡 Prompt
Lighting may include sidelight, backlight, or rim light to evaluate realism in directional illumination.
The portrait should include accurate pores, micro-reflections, eye highlights, and hair-edge glow.
Background should be softly blurred. Output in 4K–8K.
🎯 Purpose
Tests:
- photorealism
- skin texture fidelity
- cinematic lighting
- face symmetry + natural color tone
- shallow DOF and optical realism

Comparison 5: Realistic Food Photography
💡 Prompt
Show crisp flakes, buttery layers, soft interior texture, and warm natural café lighting.
Include shallow depth of field and realistic crumb details.
The final output should resemble high-end commercial food photography.
🎯 Purpose
Tests:
- micro-texture rendering
- translucency (butter layers)
- realistic food color tones (no “AI muddiness”)
- commercial-grade lighting
- lens accuracy + optical bokeh
Why this test matters: Food photography exposes model weaknesses in surface detail, color realism, and texture accuracy — areas where generative models often struggle.

Comparison 6: Architecture & Interior Design Visualization
💡 Prompt
Materials (fabric, wood, stone) must be accurately rendered, and shadows should behave realistically.
Perspective should remain consistent with professional interior photography.
🎯 Purpose
Tests:
- perspective accuracy
- material realism
- furniture geometry
- aesthetic coherence
- interior light physics
This test highlights whether the model can maintain straight lines, material accuracy, and balanced lighting — critical for architectural workflows.

Comparison 7: Product Rendering (Studio Shot)
💡 Prompt
Show reflective metal rings, soft LED accents, and smooth shadow falloff.
The product must appear manufacturable, with precise geometry and realistic materials.
🎯 Purpose
Tests:
- industrial design accuracy
- reflections and specular highlights
- geometry consistency
- realism under studio lighting
This is an essential benchmark for creators working in e-commerce, advertising, and consumer product visualization.

After reviewing the text-to-image result, which AI image generator do you personally prefer?
AIPURE’s Conclusion
Overall, both AI models are powerful in their own ways — but within the AIPURE team, Nano Banana Pro stands out as the favorite. Its outputs feel more natural, cohesive, and stylistically complete. For example, in Comparison 1: Infographic / Educational Illustration, the entire image produced by Nano Banana Pro can be used directly in a presentation or educational post. In contrast, FLUX.2 Pro tends to generate visually strong elements, but often better suited as parts of a larger slide rather than a full standalone visual.
Nano Banana Pro is ideal for creators who want holistic, layout-ready artwork, while FLUX.2 Pro excels at generating single, highly detailed subjects. In cases like Comparison 5: Realistic Food Photography or Comparison 7: Product Rendering (Studio Shot), the croissant and the headphones from FLUX.2 Pro showcase exceptional surface detail, lighting control, and realism.
However, generation performance is another key difference:
FLUX.2 Pro is consistently fast, usually completing an image in under 30 seconds.
Nano Banana Pro, while producing excellent results, can occasionally fail to generate on the first try and sometimes requires over 3 minutes to finish an image.
These impressions reflect the experience of the AIPURE team — they can serve as a reference, but ultimately, only you can decide which model fits your workflow best. The real answer will come from your own hands-on testing.
So what are you waiting for?
It’s time to unleash your creativity and generate your own amazing images!
