作为 OpenAI 函数的工具

本笔记本介绍了如何将 LangChain 工具作为 OpenAI 函数使用。

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

API 参考：

• ChatOpenAI 来自 langchain.chat_models
• HumanMessage 来自 langchain.schema

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

from langchain.tools import MoveFileTool, format_tool_to_openai_function  

API 参考：

• MoveFileTool 来自 langchain.tools
• format_tool_to_openai_function 来自 langchain.tools

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}'}
