from openai import OpenAI

client = OpenAI(
    api_key="sk-xxxxxxxxxx",

)

# Use GPT-4
response = client.chat.completions.create(
    model="gpt-5.2",
    messages=[{"role": "user", "content": "Hello!"}]
)

# Switch to Claude - just change the model name
response = client.chat.completions.create(
    model="claude-sonnet-4-20250514",
    messages=[{"role": "user", "content": "Hello!"}]
)
```
