Virtual Try-On Workflow: From User Upload to AI-Generated Image

4 min read
By Chloe Anderson

Introduction

The virtual try-on workflow enables fashion brands and technology teams to replace traditional 3D fitting with a faster, more scalable, and more cost-effective AI pipeline. By leveraging optimized APIs, teams can deliver high-quality try-on images in seconds while maintaining stability under high load.

Why Replace Traditional 3D Try-On?

Key Challenges with 3D Try-On

  • High development cost and long production cycles
  • Requires specialized 3D modelling skills
  • Often slow to render under high traffic

Benefits of AI-Based Virtual Try-On

  • Official-grade image quality without 3D rendering complexity
  • Consistent 10-second generation times
  • Straightforward integration into existing product pages or fitting apps
  • Cost-effective at scale

Workflow Overview

The process moves from user upload, through AI generation, to a completed virtual try-on image.

Step 1: User Upload

  • Accepts photo via web or mobile interface
  • Automatic validation (resolution, face detection, clothing visibility)
  • Optional background removal and image normalization

Step 2: API Request to AI Model

Our AI pipeline connects seamlessly with Nano Banana model equivalents:

  • gemini-2.5-flash-image for standard try-on outputs
  • gemini-3-pro-image-preview for advanced pro styling options

Step 3: Image Generation

  • 10-second average generation time
  • Stable outputs even under high concurrent requests
  • Return format in base64 for direct embedding

Step 4: Image Delivery

  • Serve via CDN for global users
  • Embed into UX instantly with minimal delay

API Integration Example

Basic image generation request:

curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: sk-hUdyZM5408OFCjHhdvvsQOtVO4X6FKut8X4azpMBcK7ZXbyx' \
--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/9105_output_1794ff4b.jpeg"},"type": "image_url/base64"}]}
  ],
  "stream": false
}'

Pricing Advantage

Standard Model Pricing

  • Official Nano Banana: 0.039 USD/image
  • Our pipeline: 0.02 USD/image
  • Savings: ~48% per image

Pro Model Pricing

  • Official Nano Banana Pro: 0.134 USD/image
  • Our Pro pipeline: 0.068 USD/image
  • Savings: ~49% per image

Impact at Scale

For 100,000 images:

  • Official cost: $3,900
  • Our cost: $2,000
  • Savings: $1,900

UX Considerations

Key Principles

  • Minimal friction from photo upload to result display
  • Inline progress indicators (10-second feedback)
  • Optional "Compare" mode for before/after

Integration Time

  • Most dev teams complete integration in under 10 minutes

Extensions Beyond Fashion

While fashion is the primary use case, this workflow adapts well to:

  • Eyewear try-on
  • Cosmetic previews (lipstick, hair color)
  • Furniture placement in rooms

Video Generation Option (Sora AI)

For brands needing video-based previews:

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"

Pricing:

  • Official Sora AI video: 1.0–1.5 USD/video
  • Our pipeline: 0.12 USD/video

Architecture Diagram

Logical Flow

  1. User Upload → Client
  2. Preprocessing → Background removal, normalization
  3. Model Request → API call, choose model type
  4. Image Generation → AI rendering (~10s)
  5. Delivery → Base64 to client, optional CDN cache

Drop-In Replacement

  • Directly replace existing Nano Banana endpoints with ours
  • Maintain same data structures and response formats

Performance Considerations

  • High concurrency stability due to optimized queue
  • Edge-cached CDN delivery
  • API latency measured consistently under load

Security and Compliance

  • HTTPS only
  • Token-based authentication
  • No PII stored after generation completes

Conclusion

By replacing costly, slow 3D try-on models with an optimized AI-based virtual try-on workflow, teams achieve better performance, faster integration, and significant cost savings. With ready-to-use endpoints and proven stability under load, this pipeline is a practical choice for any technical team aiming to scale virtual fitting solutions.
