Tools as OpenAI Functions

This notebook goes over how to use LangChain tools as OpenAI functions.

from langchain.schema import HumanMessage
from langchain_openai import ChatOpenAI

model = ChatOpenAI(model="gpt-3.5-turbo-0613")

from langchain.tools import MoveFileTool, format_tool_to_openai_function

tools = [MoveFileTool()]
functions = [format_tool_to_openai_function(t) for t in tools]

message = model.predict_messages(
    [HumanMessage(content="move file foo to bar")], functions=functions
)

message

AIMessage(content='', additional_kwargs={'function_call': {'name': 'move_file', 'arguments': '{\n  "source_path": "foo",\n  "destination_path": "bar"\n}'}}, example=False)

message.additional_kwargs["function_call"]

{'name': 'move_file',
 'arguments': '{\n  "source_path": "foo",\n  "destination_path": "bar"\n}'}
