Read on for side-by-side examples, quick verdicts, and actionable recommendations for integrating either model into your pipeline.
Portrait (skin tones & detail)
Portrait tests human-subject fidelity, especially skin tones and facial micro-details that reveal color bias, oversmoothing, or artifacting. A studio portrait with controlled lighting exposes differences in texture rendering, hair strands, bokeh handling, and subtle shadowing. Comparing outputs shows which model preserves ethnicity-accurate tones, realistic pores, and natural hair, making portrait prompt essential when assessing both aesthetic quality and fairness across diverse subjects, and overall downstream editing requirements for professional workflows.
Prompts: Photorealistic studio portrait of a middle-aged South Asian woman, natural and varied skin tones, soft directional key light, 85mm lens bokeh, ultra-detailed skin texture, realistic hair strands, neutral seamless background, 3:4 aspect, 4k resolution
The two images demonstrate how differently Seedream 4.5 and Nano Banana Pro interpret the same prompt. Seedream 4.5's output (Left) presents a highly intimate close-up with pronounced micro-details: skin pores, fine hair strands, and subtle specular highlights are rendered with striking precision. The directional key light creates strong contouring, and the shallow depth of field produces convincing 85mm-style compression and bokeh, giving the portrait a cinematic realism.
Nano Banana Pro's result (right) takes a more traditional studio-portrait approach. Its rendering is softer, with smoother transitions in skin tone and less aggressive textural emphasis. The lighting is more even, producing a calm and natural look. Hair appears realistic, but the broader framing introduces more environmental context, prioritizing overall balance over hyper-detail.
Overall, Seedream 4.5 excels in tactile realism and intensity, while Nano Banana Pro emphasizes subtlety, softness, and a classic portrait feel.
Product + text (logo & text legibility)
Product-plus-text prompts evaluate a model's ability to render materials, sharp edges, and crucially readable typography or logos. Close-up product photography challenges reflections, specular highlights, and surface finish—matte versus glossy—which reveal how physically plausible the output is. Testing with a visible brand name checks for text clarity, anti-aliasing, and artifact-free lettering, important for commercial use where legibility and brand fidelity determine real-world usability and downstream tasks like automated OCR and e-commerce presentation.
Prompts: Close-up product photo of matte-black wireless headphones on a white reflective surface, visible brand text "AURIX" on earcup, crisp edge detail, shallow depth of field, studio rim lighting, photorealistic, 1:1 aspect, 4k
The two images produced from the same prompt share a consistent visual identity, yet they reveal notable differences in composition and emphasis. Seedream 4.5 image (Left) adopts an extremely tight close-up, highlighting the texture of the matte-black earcup and the precision of the “AURIX” branding. Its shallow depth of field draws attention to surface detail, creating a more intimate, product-focused aesthetic. This version aligns strongly with the “close-up” and “crisp edge detail” elements of the prompt.
Nano Banana Pro (Right), by contrast, presents a fuller view of the headphones, showing the headband structure and control buttons. It feels more like a commercial product showcase rather than a macro shot. While it still reflects the photorealistic and studio-lit qualities specified, the broader framing shifts the focus from micro-detail to overall design.
Together, the two outputs demonstrate how a single prompt can yield variations in perspective while maintaining consistent stylistic cues.
Infographic / diagram (typography & layout)
Infographics test a model's capacity to produce clear, information-dense graphics with legible labels and consistent iconography. Generating diagrams requires strict spatial hierarchy, vector-like sharpness, and adherence to typographic constraints that most image models struggle with. This prompt reveals whether a model prioritizes visual clarity or artistic texture, and whether it can reliably produce assets suitable for documentation, tutorials, or marketing—where misrendered labels increase editorial workload through manual correction.
Prompts: Clean infographic: "How a smartphone battery works" — labeled cross-section diagram, legible sans-serif labels, consistent icon set, flat color palette, clear hierarchy, 1920x1080, vector-like clarity
The two infographics both illustrate the operation of a smartphone battery, but they differ significantly in focus and detail.
The Seedream 4.5 (Top) generated a concise, labeled cross-section focusing on the components of the lithium-ion battery: the Anode, Cathode, Electrolyte, and Separator. It uses a clean, flat-color, vector-like style and provides brief, static descriptions of each part's function (e.g., "Anode stores lithium ions during charging"). This diagram is excellent for quickly identifying the physical structure.
In contrast, Nano Banana Pro's image (Bottom) is a more dynamic process diagram. While it includes the same core components, its primary goal is to explain the charge/discharge cycle. It clearly separates the process into DISCHARGING (Powering the Phone) and CHARGING (Replenishing Energy), detailing the three-step flow of Lithium ions and electrons for both states. This infographic is superior for understanding the electrochemical mechanism and energy conversion (Chemical to Electrical) that powers the device.
Complex crowded scene (composition & occlusion)
Complex crowded scenes stress-test composition, occlusion handling, and inter-object consistency—areas where generative models commonly make mistakes like duplicated limbs or misplaced elements. A bustling market introduces varying scales, overlapping textures, and intricate shadows that expose whether a model maintains spatial coherence across the frame. This prompt highlights differences in global scene understanding, artifact prevalence, and how each model balances detail preservation with coherent, believable scene layout, especially when used for editorial or cinematic production.
Prompts: Busy outdoor street market at golden hour, dozens of vendors and colorful fabrics, complex occlusions and overlapping people, realistic shadows and reflections, high dynamic range, 16:9, photorealistic
Both Seedream 4.5 (Top) and Nano Banana Pro (Bottom) successfully render the prompt for a busy outdoor street market at golden hour, yet they convey distinctly different atmospheres and settings.
Seedream 4.5 presents a more dramatic and enclosed scene, likely within a covered souk or bazaar, characterized by deep, contrasting shadows and harsh backlighting. The cobblestone path, the hanging textiles (primarily red, blue, and yellow), and the focus on overhead canopy structures create a sense of being deep within a dense, historic marketplace, possibly North African or Middle Eastern. The dramatic lighting and prominent, elongated shadows are the central visual element, giving the scene a painterly, somewhat stylized appearance.
In contrast, Nano Banana Pro offers a more open and detailed view. The setting appears to be an Indian or South Asian street market, evidenced by the clothing and the visible architecture, including brick buildings and balconies. The golden hour light is softer and more diffused, illuminating a wider variety of goods, including vibrant fresh produce alongside textiles.
Action Motion (Action Scenes: Human Anatomy & Motion Blur)
Action-motion prompts evaluate anatomy accuracy, dynamic motion blur, and temporal coherence in a single frame. Capturing a sprinter mid-stride pressures the model to render correct limb positions, muscle tension, and realistic motion trails without introducing distortions or extra appendages. This reveals whether a model handles fast movement naturally, preserves anatomical plausibility, and produces images suitable for sports photography, advertising, or motion-study illustrations, and whether post-processing is required to fix dynamic artifacts.
Prompts: Action shot of a sprinter mid-stride on a red track, natural anatomy, dynamic motion blur, stadium lighting, accurate muscle tension, 3:2 aspect, high detail
Both Nano Banana Pro (Bottom) and Seedream 4.5 (Top) depict a sprinter mid-stride, meeting the prompt's requirement for an action shot with accurate muscle tension, but they differ significantly in style and setting.
Nano Banana Pro adopts a photorealistic, documentary style. The setting is clearly an outdoor track stadium, possibly at dusk, with visible crowds and real-world sponsor logos in the background. The lighting is naturalistic, highlighting the athlete's physique with high detail and realistic texture. The motion blur is subtle, primarily focusing on the movement of the athlete's legs and the sharpness of the runner in contrast to the slightly blurred crowd, conveying a genuine moment captured during a competition.
In contrast, Seedream 4.5 is highly stylized and dramatic. It features an intense, monochromatic red color scheme dominating the track, uniform, and stadium backdrop. The lighting is artificial and theatrical, with blinding floodlights creating strong highlights and lens flare. The motion blur is much more pronounced, adding a sense of extreme speed and dynamism to the background and the track lines. This image prioritizes visual impact and a heightened, almost cinematic portrayal of speed over the grounded realism found in Nano Banana Pro.
Conclusion
Seedream 4.5 and Nano Banana Pro each solve different creative problems.
