Krea AI's Nano Banana Pro is a blast to use, but the costs really sting
Krea AI is currently one of the most popular AI creative suites on the market, offering a powerful mix of image, video, and 3D generation tools. Among its lineup, Nano Banana Pro (Google's Gemini 3 Pro Image) has become the platform's hottest image model, thanks to its native 4K output and an impressive 94% accuracy in text rendering.
However, once you start using it seriously, you'll find that Krea's billing model has a few pain points that can be a real headache:
| Pain Point | The Specifics | The Impact |
|---|---|---|
| High unit consumption | Nano Banana Pro costs ~119 units per image | Your quota disappears incredibly fast |
| No quota rollover | Unused units are cleared at month-end | You end up wasting paid resources |
| Free tier limits | 50 uses/day, watermarks, low resolution | Not suitable for commercial work |
| No standalone API | Must be used via the Krea platform | You can't integrate it into your own products |
| 4K consumption doubles | High resolution requires even more units | Costs climb even higher for quality output |
🎯 The Core Issue: Krea AI is perfect for creative exploration within its own interface. However, for developers who need stable API access, batch generation, or are simply cost-conscious, the compute unit model just isn't the most economical choice.
Real Cost Analysis of Krea AI Nano Banana Pro
Let's talk numbers and calculate the real cost of using Nano Banana Pro on Krea:
2.1 Krea AI Plans vs. Computation Units
| Plan | Monthly Fee | Computation Units | Images generated with Nano Banana Pro |
|---|---|---|---|
| Free | $0 | Limited (approx. 500) | ~4 images/day |
| Basic | $10 | ~5,000 | ~42 images |
| Pro | $35 | ~20,000 | ~168 images |
| Max | $60 | ~35,000 | ~294 images |
Note: The above figures are estimates based on 119 computation units per image. Actual consumption may vary depending on resolution and parameters.
2.2 Unit Price Comparison
| Plan | Monthly Fee | Images Generated | Unit Price | vs Official $0.24 |
|---|---|---|---|---|
| Basic | $10 | ~42 images | $0.238/img | 99% |
| Pro | $35 | ~168 images | $0.208/img | 87% |
| Max | $60 | ~294 images | $0.204/img | 85% |
Key Findings:
- Not exactly cheap – Even with the Max plan, the unit price is $0.204, which is very close to official pricing.
- Quotas don't roll over – If you don't use them, you lose them. This can make the actual unit price even higher.
- No API access – You're restricted to manual operations on the Krea platform.
- Free version is unusable – Watermarks and low resolution make it unsuitable for commercial use.
💡 The Reality: Many users buy the Pro plan but only end up using half their quota each month. This effectively doubles their real unit price to $0.40+.

3-Step Guide to Migrating from Krea AI to APIYI
5.1 Step 1: Get Your API Key
- Visit APIYI at
apiyi.comand register an account. - Create an API Key in the dashboard.
- Top up your account balance (supports Alipay and WeChat).
5.2 Step 2: Choose Your Integration Method
APIYI supports two invocation methods, making it a perfect fit for your existing code:
Option 1: Official Google Format (Recommended for those familiar with Google APIs)
import google.generativeai as genai
# Just replace the endpoint and key; everything else stays the same as the official docs
genai.configure(
api_key="your-apiyi-key",
transport="rest",
client_options={"api_endpoint": "https://api.apiyi.com"}
)
model = genai.ImageGenerationModel("imagen-3.0-generate-002")
result = model.generate_images(
prompt="A cyberpunk street scene at night, neon lights, 4K ultra detailed",
number_of_images=1,
aspect_ratio="16:9"
)
result.images[0].save("output.png")
📚 Official Format Reference: Check out the Google official documentation at
ai.google.dev/gemini-api/docs/image-generation. APIYI is fully compatible; you just need to swap the endpoint.
Option 2: OpenAI-Compatible Format (Recommended for most developers)
import openai
client = openai.OpenAI(
api_key="your-apiyi-key",
base_url="https://api.apiyi.com/v1" # APIYI unified interface
)
response = client.images.generate(
model="nano-banana-pro",
prompt="Professional product photo, wireless earbuds on marble surface, studio lighting, 4K",
size="1024x1024",
quality="hd"
)
print(response.data[0].url)
5.3 Step 3: Migrate Your Workflow in Bulk
If you have a set creative process on Krea, here’s how to move it over:
| Krea Action | APIYI Equivalent |
|---|---|
| Entering prompts on the Krea canvas | Call the images.generate API endpoint |
| Using Krea style presets | Add style descriptions directly to your prompt |
| Downloading generated images | Download from the returned URL or decode the base64 string |
| Batch generating multiple images | Loop the API call or use the n parameter |
Node.js and cURL Code Examples
6.1 Node.js Example
import OpenAI from 'openai';
const client = new OpenAI({
apiKey: 'your-apiyi-key',
baseURL: 'https://api.apiyi.com/v1' // APIYI Endpoint
});
async function generateImage(prompt, size = '1024x1024') {
const response = await client.images.generate({
model: 'nano-banana-pro',
prompt: prompt,
size: size,
quality: 'hd'
});
return response.data[0].url;
}
// Usage Example
const imageUrl = await generateImage(
'Minimalist logo design for a tech startup, clean lines, modern'
);
console.log('Generated:', imageUrl);
6.2 cURL Example
curl -X POST "https://api.apiyi.com/v1/images/generations" \
-H "Authorization: Bearer your-apiyi-key" \
-H "Content-Type: application/json" \
-d '{
"model": "nano-banana-pro",
"prompt": "Architectural visualization, modern glass building, sunset lighting, 4K",
"size": "1024x1024",
"quality": "hd"
}'
6.3 Batch Generation Example
import openai
import asyncio
client = openai.OpenAI(
api_key="your-apiyi-key",
base_url="https://api.apiyi.com/v1"
)
async def batch_generate(prompts: list) -> list:
"""Batch generate images - something Krea can't do"""
results = []
for prompt in prompts:
response = client.images.generate(
model="nano-banana-pro",
prompt=prompt,
size="1024x1024",
quality="hd"
)
results.append(response.data[0].url)
return results
# Batch generate 10 product photos
prompts = [
f"Product photo of smartphone case color {color}, clean background, studio lighting"
for color in ['red', 'blue', 'green', 'black', 'white', 'pink', 'purple', 'orange', 'yellow', 'gray']
]
# On Krea, this would require 10 manual operations
# With APIYI, a single loop handles it all
urls = asyncio.run(batch_generate(prompts))
print(f"Generated {len(urls)} images")
