Embedding models
Embedding models create a vector representation of a piece of text.
This page documents integrations with various model providers that allow you to use embeddings in LangChain.
Select embeddings model:
pip install -qU langchain-openai
import getpass
import os
if not os.environ.get("OPENAI_API_KEY"):
os.environ["OPENAI_API_KEY"] = getpass.getpass("Enter API key for OpenAI: ")
from langchain_openai import OpenAIEmbeddings
embeddings = OpenAIEmbeddings(model="text-embedding-3-large")
embeddings.embed_query("Hello, world!")
