## Using Opper AI

We use [Opper AI](https://opper.ai) for LLM response generation and knowledge base integration. The response generation follows a pattern:

```python
def bake_response(messages):
    response, _ = opper.call(
        name="generate_response",
        instructions="Generate a helpful, friendly but brief response to the user's message in the conversation.",
        input={"messages": messages},
        output_type=str,
    )
    return response
```
