AnthropicLLM
本示例介绍如何使用 LangChain 与 Anthropic
模型进行交互。
安装
%pip install -qU langchain-anthropic
环境设置
我们需要获取一个 Anthropic API 密钥,并设置 ANTHROPIC_API_KEY
环境变量:
import os
from getpass import getpass
os.environ["ANTHROPIC_API_KEY"] = getpass()
用法
from langchain_anthropic import AnthropicLLM
from langchain_core.prompts import PromptTemplate
template = """Question: {question}
Answer: Let's think step by step."""
prompt = PromptTemplate.from_template(template)
model = AnthropicLLM(model="claude-2.1")
chain = prompt | model
chain.invoke({"question": "What is LangChain?"})
