Nano Banana began with a stellar reputation. Its astonishing consistency in AI image generation was compared to the precision of professional photo-editing software. Once its power became clear, adoption spread rapidly — almost uncontrollably — across creative workflows.
Flowtra, known for delivering cost-effective AI advertising solutions for small businesses, had originally relied on GPT-4o to interpret product photos and generate ad covers. While GPT-4o’s output was good, it still fell short in image accuracy compared to Nano Banana.
Facing Nano Banana’s rising popularity, Flowtra turned to its long-time trusted infrastructure partner, KIE.AI. The platform quickly released a Nano Banana API, allowing Flowtra to seamlessly adapt its system to the new standard.
Inspired by creators like RoboNuggets on YouTube, Flowtra rolled out an entirely new AI-driven advertising pipeline — bringing their AI Advertising 2.0 vision to life.
Step 1: Preparing the Product Photo
Every AI workflow begins with a high-quality product photo. For this case study, Flowtra used a classic Happy Dog pet food image:
Happy Dog Sensible Montana Dry Food
Step 2: Understanding & Designing with Gemini 2.0 Flash
The first stage splits into two subtasks:
- Interpret the product photo
- Generate multiple design variations
Flowtra selected Gemini 2.0 Flash — a model praised for its cost efficiency and reliability — to handle this process.
2.1 AI Interpretation of the Product
The model analyzed the photo and output a structured understanding of the product, including type, brand, color palette, and design style:
{
"type": "product",
"visual_description": "The image shows a bag of Happy Dog Montana dog food. The bag is green and features an image of a German Shorthaired Pointer dog, along with the product name and other details.",
"brand_name": "Happy Dog",
"color_scheme": [
{ "hex": "#225A3F", "name": "Dark Green" },
{ "hex": "#FFFFFF", "name": "White" },
{ "hex": "#A0785A", "name": "Brown" }
],
"font_style": "sans-serif"
}
This shows how accurately AI can capture essential visual elements — from the brand name to color schemes.
2.2 Generating Ad Cover Concepts
Next, the AI produced alternative ad cover concepts while still grounding its output in the original photo.
Here’s one example result:
{
"ad_copy": "Unleash their inner happiness with Happy Dog!",
"product": "Happy Dog Sensible Montana - Horse Recipe",
"character": "Energetic German Pointer puppy",
"visual_guide": "A young German Pointer puppy playfully jumping amidst a field of dandelions, with a bag of Happy Dog food subtly placed in the background. Bright, sunny day to convey energy and happiness.",
"primary_color": "Green",
"tertiary_color": "White",
"text_watermark": "None",
"secondary_color": "Yellow"
}
The AI not only provided slogans but also visual direction, making it easier to craft engaging ad concepts.
Finally, both nodes’ results were combined into a unified image prompt template (simplified here):
Your task: Create 1 image prompt as guided by your system guidelines.
Description of the reference image: {{ }}
ELEMENTS FOR THIS IMAGE:
product: {{ }}
character: {{ }}
ad copy: {{ }}
visual_guide: {{ }}
text_watermark: {{ }}
Primary color: {{ }}
Secondary color: {{ }}
Tertiary color: {{ }}

Step 3: Generating Covers with Nano Banana
At this stage, Nano Banana takes over. Using the structured prompts and the original product photo, it generates hyper-realistic covers within seconds.
The results show near-perfect fidelity: packaging details remain intact, while the pet visuals are lifelike and natural.
Step 4: Bringing Ads to Life with Veo 3
Finally, Flowtra leveraged Veo 3, the world’s leading AI video generation model, to produce dynamic ad videos.
The motion looks natural — the dog’s movements mirror real-world physics, and the packaging remains stable throughout. This level of detail is critical for brand credibility.
Cost Efficiency: High-End AI Ads for Under $1
Thanks to KIE.AI’s low-cost infrastructure, both Nano Banana and Veo 3 are accessible at unbeatable prices. Using Veo 3 Fast mode, a complete ad campaign costs less than $1 per concept — making enterprise-level AI advertising available to even the smallest businesses.
Conclusion
By integrating Nano Banana’s image accuracy with Veo 3’s advanced video generation, Flowtra has redefined what’s possible in AI-powered advertising.
- For small businesses, this workflow delivers high-quality ads at minimal cost.
- For the industry, it proves that AI Advertising 2.0 is no longer futuristic — it’s here, now.
With reliability, consistency, and affordability at its core, Flowtra’s new pipeline shows that the future of digital advertising is not just automated — it’s beautifully human-like and accessible to all.
