UpstageEmbeddings

This notebook covers how to get started with Upstage embedding models.

Installation​

Install langchain-upstage package.

pip install -U langchain-upstage

Environment Setup​

Make sure to set the following environment variables:

import os

os.environ["UPSTAGE_API_KEY"] = "YOUR_API_KEY"

Usage​

Initialize UpstageEmbeddings class.

from langchain_upstage import UpstageEmbeddings

embeddings = UpstageEmbeddings()

API Reference:

Use embed_documents to embed list of texts or documents. 

doc_result = embeddings.embed_documents(
    ["Sam is a teacher.", "This is another document"]
)
print(doc_result)

Use embed_query to embed query string.

query_result = embeddings.embed_query("What does Sam do?")
print(query_result)

Use aembed_documents and aembed_query for async operations.

# async embed query
await embeddings.aembed_query("My query to look up")
# async embed documents
await embeddings.aembed_documents(
    ["This is a content of the document", "This is another document"]
)

Using with vector store​

You can use UpstageEmbeddings with vector store component. The following demonstrates a simple example.

from langchain_community.vectorstores import DocArrayInMemorySearch

vectorstore = DocArrayInMemorySearch.from_texts(
    ["harrison worked at kensho", "bears like to eat honey"],
    embedding=UpstageEmbeddings(),
)
retriever = vectorstore.as_retriever()
docs = retriever.invoke("Where did Harrison work?")
print(docs)
