In 2025, AI image tools are evolving at lightning speed. Two names getting a lot of buzz are Nano Banana (Google’s Gemini image editing model) and Seedream 4.0 (ByteDance’s next-gen unified generation and editing system).

Both promise powerful capabilities, but depending on what you need (editing existing photos, generating new images, consistency, speed, or API access), one may suit you better. In this post, we’ll break down what they can do, how they differ, and when to pick one over the other, with simple analogies, and how Vibemyad offers you a one-stop destination to create your ad.

Creative production isn’t just about speed; it’s about scalability with precision. Marketing analysts know the pain: balancing brand identity with constant content demand across markets and platforms.

This is exactly where AI models like Nano Banana and Seedream 4.0 shine and why Vibemyad leverages both to give brands a competitive edge.

What Are They?

Nano Banana (Google Gemini Image Editing)

Nano Banana is Google’s Gemini-powered image editing model. It focuses on making subtle but accurate changes to your existing photos without distorting faces or features. Think of it as a magical retoucher who respects reality while enhancing it.

Industry use-case:

• A fashion e-commerce brand uploads product photos and edits background colors for catalog consistency.
• A wedding photographer swaps dull skies for golden sunsets without losing the couple’s real expressions.

“Nano Banana = identity-first editing.”

Seedream 4.0

Seedream 4.0 is ByteDance’s multi-purpose AI studio for both generation and editing. It allows multi-image references, 4K resolution, and fast inference (~1.8s for 2K outputs). Think of it as a full architecture firm, building new worlds from scratch and remodeling existing ones.

Industry use-case:

• A marketing agency generates ad campaigns across multiple styles while keeping the brand’s identity consistent.
• An indie game designer creates concept art across environments while keeping characters visually the same.

“Seedream 4.0 = imagination-first creation.”

If Nano Banana is the interior designer, Seedream 4.0 is the full architecture firm, able to both create new structures and remodel existing ones.

Vibemyad’s Hybrid Edge

Most companies pick one model. At Vibemyad, we combine both intelligently:

• Nano Banana - Sharp edits, identity preservation, quick retouching.
• Seedream 4.0 - Campaign scaling, new asset generation, multi-style consistency.

This means:Your product still looks like your product (no “AI drift”).Your campaigns can scale across markets, languages, and channels in record time.Your analysts get measurable performance lifts because creatives are consistent, optimized, and platform-ready.

In short, Vibemyad doesn’t just make ads; we make brand-true ads at scale.

Side-by-Side Comparison

We tried putting same prompts in both the models and tried generating ads. Let me first, give you the reference image

Lenskart Ad for eyewear

The prompt that we used is:

Extreme close-up of a model wearing stylish glasses, both eyes and the full frame of the glasses are visible very close to the camera, with the model looking straight into the lens. Only the eyes and glasses are in frame; no other facial features are visible, the rest is softly blurred and cropped out. Directly below the eyes, write VERY BIG, bold, all-caps white text: "IT'S LIKE HAVING CUSTOMIZABLE EYE" in a modern sans-serif font, with no background behind the text—the text should be written over the model's face. Editorial, premium fashion ad, bright soft studio lighting.

Generated images using first prompt

The next prompt that we used is:

Make the glasses pink tiger skin

Generated images using second prompt

The next prompt that we used is:

A model sits on the edge of a rooftop building at sunset, facing the camera. The sunset sky and cityscape are visible in the background. The model is wearing a baggy t-shirt and jeans, with both legs hanging off the edge of the building. Zoom in on the model's face, highlighting stylish glasses, so the face and glasses are the main focus of the image, but enough background remains to show the rooftop and sunset. At the top left corner, add VERY BIG, bold text: "FRAME YOUR VIEW FROM ABOVE" in a modern, sans-serif font. The lighting should be warm and soft, editorial, premium ad style.

Scenarios: Which to Pick?

Let’s walk through some simplified scenarios to see which tool is the better pick.

Scenario 1: You have a product photo and want variants (different backgrounds/colors)

• Nano Banana: Upload your product photo, prompt “place it on a marble surface, change background to light grey, add soft shadow.” You’ll likely get a consistent result while preserving the shape and form.
• Seedream 4.0: Could also do that; especially helpful if you have multiple reference images (e.g., your product in different angles) and you want consistency across those edits.

Winner: Nano Banana gives you a quick, strong result. But if you already have multiple reference images and need automation for variants, Seedream has an edge.

Scenario 2: You want to generate brand visuals from scratch

• Nano Banana: You can use text-to-image capabilities in Gemini (e.g., “Create an illustration of a futuristic cityscape at dusk”), but it may not be as flexible or tuned for full generative creativity.
• Seedream 4.0: Built to handle generation + editing; especially good when you want to start from scratch, experiment with styles, and then refine with edits.

Winner: Seedream 4.0 is more natural in this workflow.

Scenario 3: Consistency across multiple images (e.g., for a campaign)

• Nano Banana: Has some fusion/blending support (you can combine multiple photos)
• Seedream 4.0: Explicitly supports multi-image referencing so you can maintain a visual identity (same style, color tone, subject look) across a batch of images.

Winner: Seedream 4.0.

Vibemyad Hybrid Approach

Scenario 1: Product Photo Variants (Different Backgrounds/Colors)

• Nano Banana: Instantly retouches and refines the hero product photo, fixing lighting, removing blemishes, and swapping simple backgrounds while keeping the product identity intact.
• Seedream 4.0: Scales those edits into dozens of variations, different environments, festive themes, or region-specific backdrops while keeping the product shape and style consistent across all outputs.
• Vibemyad Hybrid Edge: You get pixel-perfect base edits (Nano Banana) plus automated variant generation at scale (Seedream 4.0).

Result: One polished product photo transforms into a full catalog of campaign-ready assets across markets.

Scenario 2: Generating Brand Visuals from Scratch

• Seedream 4.0: Creates bold, high-resolution concepts, futuristic cityscapes, festival backdrops, or completely new campaign worlds from scratch. Perfect for exploration and experimentation.
• Nano Banana: Once visuals are generated, Vibemyad uses them to refine brand-sensitive details, logos, packaging, and models, ensuring they remain true-to-brand and ad-ready.
• Vibemyad Hybrid Edge: You get unlimited creative exploration (Seedream) anchored with brand-safe refinements (Nano Banana).

Result: Wild creative ideas get transformed into professional, brand-aligned campaign visuals.

Scenario 3: Consistency Across Multiple Images (Campaigns)

• Seedream 4.0: Ensures multi-image referencing, maintaining consistent style, color tone, and subject look across an entire batch of campaign assets (e.g., social, print, and video frames).
• Nano Banana: Fine-tunes each asset for platform-specific polish, ensuring logos, typography, and faces remain consistent without drift.
• Vibemyad Hybrid Edge: You get cohesive campaigns (Seedream) plus per-image refinement for compliance and platform optimization (Nano Banana). 

Result: Campaigns that look unified across every channel while staying sharp and ad-compliant.

Bottom Line:

• Nano Banana - precision editor
• Seedream 4.0 - creative powerhouse
• Vibemyad - the bridge that makes both work seamlessly for marketers

Final Thoughts & Recommendations

• For precise, identity-safe edits: If your primary goal is retouching existing photos with minimal effort and keeping brand integrity intact, Nano Banana excels. It ensures faces, products, and logos remain true to the brand while delivering polished visuals quickly.
• For scalable, creative workflows: If your campaigns require generating new visuals from scratch, maintaining consistency across multiple assets, or integrating with APIs for automation, Seedream 4.0 is the stronger fit. It allows high-resolution, multi-style campaigns at scale with flexible editing options.
• The Vibemyad advantage: In practice, marketing teams don’t need to choose one over the other. Vibemyad combines the strengths of both models using Nano Banana for quick, brand-safe edits and Seedream 4.0 for batch generation, campaign-wide consistency, and creative experimentation. This hybrid approach gives analysts speed, precision, and scalability in one streamlined workflow.
