Introduction

AI interior styling offers instant, personalized home decor recommendations. For e-commerce and soft furnishing platforms, it's a chance to enhance engagement and conversion.

Unique Approach: LLM + Image Generation

Combining a large language model's reasoning with high-quality image generation lets you:

  • Suggest colors and furniture tailored to user tastes
  • Produce layout ideas that balance form and function
  • Show realistic visuals in 10 seconds

Users see both the recommendation and the finished image without leaving your platform.

Cost Advantage

Nano Banana Pro pricing is significantly lower than official rates:

  • Official standard price: 0.039 USD/image
  • Our stable quality: 0.02 USD/image with 10-second base64 return
  • Nano Banana Pro: 0.068 USD/image vs. official 0.134 USD/image When generating images at scale, savings are substantial while keeping performance consistent.

For Video Content

Sora AI Video via our pipeline costs 0.12 USD/video compared to 1–1.5 USD/video official rate.

Core Capabilities

With this AI interior stylist setup, you can:

  • Recommend ideal color palettes for walls, fabrics, and accents
  • Suggest furniture pieces tuned to user lifestyle
  • Optimize spatial layouts for comfort and accessibility

Pipeline Overview

The AI works through:

  1. Input capture from the user (preferences, room type, dimensions)
  2. LLM processing for style recommendations
  3. Image generation of proposed designs
  4. Optional video rendering for immersive experiences

Step-by-Step Implementation

Step 1: Set Up Environment

Integrate Nano Banana API with authentication and correct model endpoints.

Step 2: Generate Furniture and Layout Suggestions

Use the LLM side to interpret inputs and produce descriptions.

Step 3: Transform Recommendations into Visuals

Feed the descriptions into image generation models.

Step 4: Optimize Outputs

Consider cropping, resizing, and formatting images for web/app display.

Image Generation Examples

Model: gemini-2.5-flash-image (Nano Banana standard) Model: gemini-3-pro-image-preview (Nano Banana Pro)

curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--data-raw '{
  "model": "gemini-2.5-flash-image",
  "messages": [{"role": "user","content": [{"text": "generate a high-quality image.","type": "text"},
        {"image_url": {"url": "https://blog-images.juhedata.cloud/sample.jpeg"},"type": "image_url/base64"}]}],
  "stream": false
}'

Expect official-grade image quality with 10-second generation time.

Video Generation for Dynamic Room Tours

Turn static designs into engaging walkthroughs.

Step 1: Make Video

curl -X POST "https://wisdom-gate.juheapi.com/v1/videos" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: multipart/form-data" \
  -F model="sora-2" \
  -F prompt="A serene lake surrounded by mountains at sunset" \
  -F seconds="15"

Step 2: Check Progress

curl -X GET "https://wisdom-gate.juheapi.com/v1/videos/{task_id}" \
  -H "Authorization: Bearer YOUR_API_KEY"

This asynchronous workflow prevents blocking and keeps user experience snappy.

Scalability and Performance Tips

  • Use caching for repeated requests with similar inputs
  • Monitor API latency and adjust request batches
  • Track usage against cost forecasts to protect margins

Conclusion

By merging LLM insight with image and video generation via Nano Banana Pro, platforms can provide interactive, instantly visualized decor ideas at a fraction of traditional costs. Deploying this pipeline accelerates design workflows for your users and adds a polished, memorable layer to the shopping or design journey.
