You.com 搜索

The you.com API 是一套旨在帮助开发人员将 LLM 的输出与最新、最准确、最相关的信息相结合的工具，这些信息可能未包含在其训练数据集中。

设置​

该工具位于 langchain-community 包中。

您还需要设置您的 you.com API 密钥。

%pip install --upgrade --quiet langchain-community
import os

os.environ["YDC_API_KEY"] = ""

# For use in Chaining section
os.environ["OPENAI_API_KEY"] = ""

## ALTERNATIVE: load YDC_API_KEY from a .env file

# !pip install --quiet -U python-dotenv
# import dotenv
# dotenv.load_dotenv()

设置 LangSmith 也很有帮助（但不是必需的），它可以提供一流的可观察性。

# os.environ["LANGCHAIN_TRACING_V2"] = "true"
# os.environ["LANGCHAIN_API_KEY"] = getpass.getpass()
