User: Tell me a joke.
Assistant: Why don't eggs tell jokes?
They might crack each other's shells,
leaving yolk on face.

Using style: robot

User: Tell me a joke.
Assistant: Beep boop! Why was the robot so bad at soccer? Beep boop... because it kept kicking up a debug! Beep boop!

$ python examples/basic/dynamic_system_prompt.py
Using style: pirate

User: Tell me a joke.
Assistant: Why did the pirate go to school?

To improve his arrr-ticulation! Har har har! 🏴‍☠️
