让我们加载OpenAI嵌入类。
from langchain.embeddings import OpenAIEmbeddings
embeddings = OpenAIEmbeddings()
text = "This is a test document."
query_result = embeddings.embed_query(text)
doc_result = embeddings.embed_documents([text])
让我们加载带有第一代模型（例如“text-search-ada-doc-001 / text-search-ada-query-001”）的OpenAI嵌入类。注意：这些不是推荐的模型-请参见此处 (opens in a new tab)。
from langchain.embeddings.openai import OpenAIEmbeddings
embeddings = OpenAIEmbeddings()
text = "This is a test document."
query_result = embeddings.embed_query(text)
doc_result = embeddings.embed_documents([text])
