Service: Azure AI Foundry – Image Generation 🧠🎨

🧩 Problem

You need to automatically generate original images from natural language descriptions, for use in marketing, illustration, branding, or similar applications.

🚀 Solution with Azure

Use image generation models available in Azure AI Foundry, such as: * 🎨 DALL-E 3 * 🖼️ GPT-Image 1

These models allow you to create unique visual content based on text prompts, rather than retrieving existing images.

🛠️ Componenti richiesti

  • Azure AI Foundry portal
  • Image generation model (e.g., DALL-E 3)
  • Images playground for prompt testing
  • REST API or SDKs (OpenAI Python SDK, Azure OpenAI .NET SDK)
  • API key for authorization

🏗️ Architettura / Sviluppo

🧪 Test using the Images playground

  • Set image resolution:
  • 1024x1024 (default)
  • 1792x1024 (wide)
  • 1024x1792 (tall)
  • Choose image quality: standard or hd
  • Choose style: natural or vivid

🔧 Build a client app

Submit a prompt to the API with parameters like:

{
  "prompt": "A badger wearing a tuxedo",
  "n": 1,
  "size": "1024x1024",
  "quality": "hd",
  "style": "vivid"
}

Response (synchronous with DALL-E 3):

{
  "created": 1686780744,
  "data": [
    {
      "url": "<URL of generated image>",
      "revised_prompt": "<prompt that was used>"
    }
  ]
}
  • ✅ url: Link to the generated PNG image
  • 🔁 revised_prompt: Optimized prompt used by the model

📌 Best practice / Considerazioni

  • 🧾 Use specific, detailed prompts for better results
  • ⚙️ Tune resolution, style, and quality for output that fits the use case
  • 🖼️ Remember: images are original, not from a database
  • 🔐 Always include authorization headers when using APIs
  • 🧪 Start with Images playground to test before integrating in an app
