OpenAI Functions and Default Prompts: How to customize the prompts

[rdhillbb]

My application is working well using the default problems. I am able to give compound instructions like:

Compare the background of Johns Hopkins and Katherine Johnson of Nasa. Save the information to the file johnHKJohnson.txt.

I have not touch the prompt and everything is working okay. It is working but my gut tells me I may need to refine down the road.
I have found any documentation to change the prompt. If some can point me in the right direction on prompts for OpenAI_Functions, much appreciated. Thank You

Below is basically what I am doing.

open_ai_agent = initialize_agent(
tools,
llm,
agent=AgentType.OPENAI_FUNCTIONS,
verbose=False,
agent_kwargs=agent_kwargs,
memory=memory,
)

resp = open_ai_agent.run(user_input)

It is working. Keep on until I have a case where it does not.
