Every time a designer assumes they have seen it all, there is a new update on the horizon, possibly AI, evidently better. Now it’s Nano Banana!
If you’re reading this, you’ll probably have an idea of why everyone is going bananas.
We’ll explain it a little better, for the designers and everyone who’s ready to add ÄI editing expertise” to their arsenal of marketable skills.
Nano Banana is a new update in Google’s Deepmind image editing and generation model featured in the Gemini app.
“It’s the top-rated image editing model in the world” says Google’s “The Keyword” blog.
The aim with this native image editor is to maintain likeness to the original image throughout the editing process. You can change the background, add a new hairstyle, edit yourself into an old family photo or completely change the entire picture without compromising on the appearance of the people in the photo. You can also convert it into videos through the Gemini app.
Now that you know what the model does, you are probably thinking it’s the same as, well, every AI image generator till date? The answer may not be simple – yet.
For a start, it is better.
This means better quality, quicker response times and improved likeness preservation.
Whether it will beat Photoshop remains to be seen, but the hype promises unrivalled quality and efficiency.
With AI powering almost all facets of content, design, marketing and whatnot, the goal for most designers is achieving efficiency, without spending hours creating every shadow, adjusting colours or using expensive resources.
Here’s how the top performing AI generators fare in the world of design:
Nano Banana
Nano Banana is built for speed, simplicity, and results.
Unlike many AI image tools that overwhelm users with complex settings, Nano Banana keeps the workflow intuitive and agile.
Its lightweight system delivers faster generations with less friction, making it ideal for creators who value efficiency and quick turnaround.
While it does not focus on extreme customisation, it provides exactly what most teams need: dependable and visually appealing outputs in a fraction of the time.
Adobe Firefly
Adobe Firefly works best inside the Creative Cloud ecosystem, offering professional editing and commercial-ready assets.
This power comes with drawbacks such as a steep learning curve, slower render times and higher costs.
Compared to Nano Banana, which takes users from idea to image in seconds, Firefly can feel heavy and less flexible for fast moving projects.
Midjourney
Midjourney is known for its artistic and highly stylized visuals and is popular with concept artists and creatives exploring bold aesthetics.
The model does requires Discord access and detailed prompting, which slows down everyday use. Nano Banana removes these hurdles and offers instant results with no extra steps.
MidJourney inspires artistry while Nano Banana delivers the speed and simplicity needed for real world content creation.
DALL·E
DALL·E provides flexibility with tools like in-painting and out-painting, making it versatile for edits and adjustments.
It often feels like a generalist tool that is good at many tasks but slower and less focused on speed.
Nano Banana outperforms in accessibility and turnaround time, giving creators straightforward outputs without delay. For teams prioritising efficiency, Nano is the sharper choice.
Stable Diffusion
Stable Diffusion is the go-to for developers and advanced users who want deep control and custom model training. It requires heavy set-up, strong hardware and technical expertise which puts it out of reach for most teams.
Nano Banana takes the opposite path with no set-up, no technical barriers and instant usability. It may not match the customization depth, but for fast and reliable results Nano is far more practical.
Therefore, we’ll get you started on the application:

Prompt idea: Reference sheet: preserve scarf, skin tone and dimple; generate scene at outdoor café terrace; same facial expression.
Restore & Re-imagine History: Repair, colourise, and enhance archival photos without losing authenticity or fine detail.
Prompt idea: colourize B&W portrait with 1940s palette; repair scratches and torn edges; preserve composition and proportions.
