NanoBanana or Seedream4.0? Why Choose When You Can Have Both

Recently, Google’s Nano Banana and ByteDance’s Seedream4.0 have become hot topics in the AI creative community.

Many are debating which is superior, but my go-to design platform, Textideo, integrates both models seamlessly. Previously, I had to switch between platforms, which made testing fragmented and inefficient. Now, I can compare models directly within a single platform, eliminating the need to choose.

Once you create a project, the chat window is on the left and the canvas on the right. After uploading images, you can select any image in a small preview window to specify detailed requests, making the creative process faster and more efficient.

E-commerce Use Case

In e-commerce, selecting models and arranging scenes often requires significant time and budget. Increasingly, brands are turning to AI to generate product images, especially when large volumes are needed.

Example: I uploaded two reference images—a girl holding a phone and the newly released iPhone 17 (I’m particularly fond of the lavender color).

• Using Seedream4.0 to replace the phone, the color was slightly off.
• Using Nano Banana, the result was smooth, natural, and true to the original color.

With Textideo, you can test multiple models and pick the one that fits your needs perfectly. Why choose one when you can have them all?

Figure Modeling

Nano Banana has been a hit since its release.

Example: I used Seedream4.0 and Nano Banana to create a 1/7-scale commercial figure placed on a desk with a transparent base and packaging box.

• Seedream4.0 sometimes requires multiple iterations to achieve an ideal result.
• Nano Banana produces more natural results, though minor imperfections can still appear.

The fun of AI-generated imagery lies in experimentation—refining and iterating until you achieve the desired outcome.

High-Resolution Photo Restoration

I restored black-and-white photos of 1990s Hollywood stars—Brenda Fricker, Juliette Lewis, Nicole Kidman, and Demi Moore—and colorized them:

• Seedream4.0: Repairs scratches, tears, and fading, with color correction and contrast adjustments.
• Nano Banana: Preserves the original style with minimal rendering, respecting the source image.

Merchandise & IP Design

Using personal pet photos, I created six different IP concepts (e.g., playing guitar, wearing a bow tie, holding a magic wand). One image was chosen as the core for a full merchandise line: tote bags, mugs, phone cases, pillows, and keychains. The designs are clean, cute, and color-coordinated.

Both models produced distinct styles, allowing flexibility in selecting the preferred direction for further production.

Hairstyle Variations

I tested five different hairstyles: French chin-length bob, loose waves with highlights, sleek high ponytail, asymmetrical pixie cut, and Korean air bangs with shoulder-length hair.

• Both Seedream4.0 and Nano Banana handled these changes well, though minor differences appeared in facial consistency and arm positioning. Overall, both models executed the instructions accurately.

Multi-Image Compositing

Combining multiple characters while maintaining consistency in clothing and appearance allows the creation of new poses and scenarios.

• Nano Banana produced more natural compositions, though some positioning details were slightly off.
• Seedream4.0’s style was more varied, with occasional stiffness in the poses.

Conclusion

The true value of AI-generated imagery lies in iterative experimentation. There is no “best” tool—only the model that fits your needs.

Textideo enables seamless switching between top-tier models, including:

• Seedream4.0
• Nano Banana
• Veo3
• Hailuo-AI
• Wan2-2
• Qwen-Image
• Seedance

You can adjust models according to your needs for optimal results. The platform also supports batch image generation, producing posters, memes, and video assets in a single click, significantly boosting productivity.

Ultimately, the essence of creation is discovering the perfect result through each experiment.
