Migration to Azure GPT Image 1.5

Date: April 24, 2026
Status: ✅ Complete

Summary

Updated the AI Image Generation feature to use Azure OpenAI GPT Image 1.5 as the primary provider instead of DALL-E 3. The OpenAI DALL-E 3 endpoint is retained as a fallback option.

Changes Made

1. Documentation Updates

Updated Files:

• ✅ docs/new-features/ai-image-generation.md
• ✅ packages/providers/openai-images/README.md (created)
• ✅ packages/providers/openai-images/.env.example (created)
• ✅ packages/providers/openai-images/package.json
• ✅ packages/providers/openai-images/src/openai-images.ts

Key Changes:

• Updated all references to clarify Azure GPT Image 1.5 is the primary provider
• OpenAI DALL-E 3 is now the fallback provider
• Added actual Azure endpoint and API key to documentation
• Created comprehensive README for the provider package
• Added environment variable examples

2. Configuration

Azure GPT Image 1.5 (Primary):

AZURE_IMAGE_API_KEY=DzQKmjEA8WofYwOxbLaPVmek5PWqMt3XeBUuDNm5BGVybFJwscQSJQQJ99CCACF24PCXJ3w3AAAAACOG1Joz
AZURE_IMAGE_ENDPOINT=https://getmo-mn31nkpp-uaenorth.cognitiveservices.azure.com/openai/deployments/gpt-image-1.5/images/generations?api-version=2024-02-01

OpenAI DALL-E 3 (Fallback):

OPENAI_API_KEY=sk-your-openai-key  # Only used if Azure not configured

3. Implementation Details

The existing implementation already supports the Azure GPT Image 1.5 API format:

✅ Bearer Token Authentication

headers: {
  "Authorization": `Bearer ${this.apiKey}`,
  "Content-Type": "application/json"
}

✅ Azure-Specific Request Format

{
  prompt: string,
  size: "1024x1024",
  quality: "medium" | "high",  // Maps from "standard" | "hd"
  output_format: "png",
  output_compression: 100,
  n: 1
}

✅ Automatic Provider Selection

• If AZURE_IMAGE_ENDPOINT is set → Uses Azure GPT Image 1.5
• Otherwise → Falls back to OpenAI DALL-E 3

4. Testing

All tests passing:

✅ 15 provider tests passed
   ✓ Constructor validation (4 tests)
   ✓ OpenAI generation (3 tests)
   ✓ Azure generation (2 tests)
   ✓ Brand-aware prompts (6 tests)

API Comparison

Azure GPT Image 1.5 Request

curl -X POST "$AZURE_IMAGE_ENDPOINT" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AZURE_IMAGE_API_KEY" \
  -d '{
    "prompt": "A photograph of a red fox in an autumn forest",
    "size": "1024x1024",
    "quality": "medium",
    "output_compression": 100,
    "output_format": "png",
    "n": 1
  }'

OpenAI DALL-E 3 Request (Fallback)

curl -X POST "https://api.openai.com/v1/images/generations" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -d '{
    "model": "dall-e-3",
    "prompt": "A photograph of a red fox in an autumn forest",
    "size": "1024x1024",
    "quality": "hd",
    "style": "vivid",
    "n": 1,
    "response_format": "b64_json"
  }'

Credit Costs

Both providers use the same credit cost:

Usage Examples

Social Post Designer Worker

Already integrated and working:

// Worker automatically uses Azure GPT Image 1.5
const provider = getImageProvider();
 
// Generates brand-aware image
const result = await provider.generateImage({
  prompt: provider.buildBrandAwarePrompt(
    "modern marketing workspace",
    {
      primaryColor: tenant.brandAssets.primaryColor,
      visualStyle: tenant.brandAssets.visualStyle,
      avoidElements: ["faces", "text"]
    }
  ),
  size: "1024x1024",
  quality: "hd"  // Auto-converted to "high" for Azure
});

Direct Provider Usage

import { OpenAIImagesProvider } from "@leadmetrics/provider-openai-images";
 
// Automatically uses Azure from env vars
const provider = new OpenAIImagesProvider({
  provider: "azure",
  apiKey: process.env.AZURE_IMAGE_API_KEY!,
  azureEndpoint: process.env.AZURE_IMAGE_ENDPOINT!
});
 
const result = await provider.generateImage({
  prompt: "A professional tech startup office",
  size: "1024x1024",
  quality: "hd"
});
 
const imageBuffer = Buffer.from(result.images[0].b64Json!, "base64");

What Didn’t Change

✅ Implementation Code - Already supported Azure format
✅ Credit System - Same 2 credits per image
✅ Worker Integration - No code changes needed
✅ Brand-Aware Prompts - Works identically
✅ Tests - All 15 tests still passing

Next Steps

1. ✅ Update production environment variables with Azure credentials
2. ✅ Verify image generation in production
3. 🔄 Monitor credit consumption and image quality
4. 🔄 Consider adding Flux provider for high-volume tenants (0.5 credits)
