# Model Configuration

> Use AskUI default or bring your own LLM.

## Default

No configuration needed. AskUI auto-selects optimal model:

```python theme={null}
with VisionAgent() as agent:
    agent.act("Fill the login form")
```

## Custom Model

```python theme={null}
with VisionAgent(model="claude-sonnet-4-20250514") as agent:
    agent.act("Complete checkout")

# Or per command type
with VisionAgent(model={
    "act": "claude-sonnet-4-20250514",
    "get": "askui",
    "locate": "askui-combo",
}) as agent:
    agent.act("Search for flights")
```
