OpenAIPydanticProgram.from_defaults but i get lost where to use it, i wanna feed the generated dict to another agent so it can call a functions.from llama_index.core.tools import FunctionTool
from llama_index.llms.openai import OpenAI
from llama_index.agent.openai import OpenAIAgent
# define sample Tool
def multiply(a: int, b: int) -> int:
"""Multiple two integers and returns the result integer"""
return a * b
multiply_tool = FunctionTool.from_defaults(fn=multiply)
# initialize llm
llm = OpenAI(model="gpt-3.5-turbo")
# initialize ReAct agent
agent = OpenAIAgent.from_tools([multiply_tool], llm=llm, verbose=True)
