Using a model

Specify the model ID in the model field of your request:

response = client.chat.completions.create(
    model="gpt-5.2",  # or "shuttleai/auto", "claude-opus-4.6", etc.
    messages=[{"role": "user", "content": "Hello!"}]
)

Not sure which model to use? Try ShuttleAI Auto — it intelligently routes your request to the best model for the job and is the most cost-efficient option.
