Tools 作为 OpenAI 函数

这个笔记本将介绍如何将 LangChain 的工具作为 OpenAI 函数使用。

from langchain.chat_models import ChatOpenAI
from langchain.schema import HumanMessage

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}'}
