Bases: BaseLLM HuggingFace Pipeline API. get_input_schema. LangChain does not serve its own LLMs, but rather provides a standard interface for interacting with many different LLMs. Jupyter notebooks are perfect for learning how to work with LLM systems because oftentimes things can go wrong (unexpected output, API down, etc) and going through guides in an interactive environment is a great way to better understand them. document import Document # テキストの準備 text = """ LangChain is a framework for developing applications powered by . llms import AzureOpenAI from langchain.
