client = OpenAI(
    api_key="sk-xxxxxxxxxx",
    base_url="https://api.gravitex.ai/v1"
)

# Use GPT-5.5
response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[{"role": "user", "content": "Hello!"}]
)

# Switch to Claude - just change the model name
response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{"role": "user", "content": "Hello!"}]
)
