使用聊天模型时会向 llm 发送什么？

Question

我对如何组合多个消息并将其发送到大型语言模型（例如

ChatOpenAI

）感到困惑。

from langchain_core.prompts import ChatPromptTemplate

template = ChatPromptTemplate.from_messages([
    ("system", "You are a helpful AI bot. Your name is {name}."),
    ("human", "Hello, how are you doing?"),
    ("ai", "I'm doing well, thanks!"),
    ("human", "{user_input}"),
])

messages = template.format_messages(
    name="Bob",
    user_input="What is your name?"
)

messages

[SystemMessage(content='You are a helpful AI bot. Your name is Bob.'),
 HumanMessage(content='Hello, how are you doing?'),
 AIMessage(content="I'm doing well, thanks!"),
 HumanMessage(content='What is your name?')]

是否生成如下所示的文本：

System:
Human:
Assistant:
Human:
...

如何打印发送给 llm 的最终文本？

Answer 1

您可以使用

format

方法将聊天模板格式化为字符串，以下是更新后的代码：

prompt = template.format(
    name="Bob",
    user_input="What is your name?"
)

prompt

输出：

System: You are a helpful AI bot. Your name is Bob.
Human: Hello, how are you doing?
AI: I'm doing well, thanks!
Human: What is your name?
