🔌 Extending with AI Services

Add Your AI Provider

Install your AI SDK:

pip install openai  # or anthropic, cohere, etc.

Configure environment:

# Add to .env
AI_SERVICE_API_KEY=sk-your-api-key
AI_SERVICE_MODEL=gpt-4

Implement service integration:

# In service layer
class AIService:
    async def generate_response(self, query: str, context: dict) -> str:
        # Your AI integration here
        return ai_response
