ChatGPT 插件

这个例子展示了如何在 LangChain 抽象中使用 ChatGPT 插件。

注意1：目前这仅适用于没有身份验证的插件。

注意2：肯定还有其他方法可以做到这一点，这只是第一次尝试。如果你有更好的想法，请提交一个 PR！

from langchain_community.tools import AIPluginTool

from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_openai import ChatOpenAI

tool = AIPluginTool.from_plugin_url("https://www.klarna.com/.well-known/ai-plugin.json")

llm = ChatOpenAI(temperature=0)
tools = load_tools(["requests_all"])
tools += [tool]
agent_chain = initialize_agent(
    tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
agent_chain.run("what t shirts are available in klarna?")

我需要检查 Klarna 购物 API，看看它是否有关于可用 T 恤的信息。
动作：KlarnaProducts
动作输入：无
观察：使用指南：使用 Klarna 插件获取任何购物或研究目的的相关产品建议。发送的查询不应包括冠词、介词和限定词。当搜索与产品相关的词语时，如它们的名称、品牌、型号或类别时，API 的效果最佳。链接将始终返回，并应显示给用户。
