🔧 Breaking Changes

This release corrects the image generation API to require explicit model selection. No automatic fallback or model selection.

Migration Required

# Old (v0.4.0)
provider = GPT4oImageProvider(api_key="...")
response = provider.generate(prompt="...")

# New (v0.4.1)  
provider = OpenAIImageProvider(api_key="...")
response = provider.generate(
    model=ImageModel.DALLE_3,  # REQUIRED
    prompt="..."
)

✨ What's New

  • Explicit Model Selection: Every request must specify which model to use
  • Three Models Available:
    • dall-e-2: Multiple images, editing, 256x256 to 1024x1024
    • dall-e-3: Styles, HD quality, up to 1792x1024, revised prompts
    • gpt-image-1: Token pricing, 4K resolution (4096x4096), better instruction following
  • Model-Specific Validation: Each model validates its specific parameters
  • Token Usage Tracking: GPT-Image-1 returns token usage information

📦 Installation
