This is from the official documentation from ChatGPT chat completion:
openai.ChatCompletion.create(
model="gpt-3.5-turbo",
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Who won the world series in 2020?"},
{"role": "assistant", "content": "The Los Angeles Dodgers won the World Series in 2020."},
{"role": "user", "content": "Where was it played?"}
]
)
My first understanding for the system role is a message that just to greeting the user. But it doesn't make sense to greet user by 'You are a helpful assistant.'.And it also explains:
The system message helps set the behavior of the assistant. In the example above, the assistant was instructed with "You are a helpful assistant."
So do I write the behavior of the AI in the system role like: You're professional assistant if I want the AI to be a pro or I can write in the role like: You're a funny assistant if I would like it to be a interesting AI.
Or it simply just a greeting message?
