Switch Between Models [#switch-between-models]

Change the `model` parameter to use any supported model — no other code changes needed. Use the [Models API](/docs/models-api) to list available models:

```python
# List available models
models = client.models.list()
for model in models.data:
    print(model.id)

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