ChatGPT 插件

ChatGPT 插件是如何在 LangChain 抽象中使用的示例。

注意 1：目前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实现这一点，这只是一个初步尝试。如果您有更好的想法，请提交 PR！

from langchain.chat_models import ChatOpenAI
from langchain.agents import load_tools, initialize_agent
from langchain.agents import AgentType
from langchain.tools import AIPluginTool
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
    观察结果：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。发送的查询不应包含冠词、介词和限定词等停用词。当搜索与产品相关的词语时，如名称、品牌、型号或类别，API 的效果最佳。链接将始终返回，并应向用户显示。
