# Example: Claude Sonnet 4.5 API Implementation
import anthropic

client = anthropic.Anthropic(api_key="your-api-key")

# Simple query - Fast Mode triggered
response = client.messages.create(
    model="claude-sonnet-4.5",
    max_tokens=1000,
    messages=[{
        "role": "user", 
        "content": "What's the current stock price of AAPL?"
    }]
)

# Complex automation task - Deep Mode triggered
automation_response = client.messages.create(
    model="claude-sonnet-4.5",
    max_tokens=4000,
    messages=[{
        "role": "user",
        "content": """Analyze our Q3 financial data, identify cost reduction 
        opportunities, create implementation timeline, assess risks, 
        and generate executive summary with recommendations."""
    }]
