langchain-s3-cached-embeddings 0.8.1

langchain embeddings wrapper to persist embeddings for re-use later

langchain-s3-cached-embeddings

Proxies any langchain Embeddings class such as OpenAIEmbeddings, GoogleGenerativeAIEmbeddings, persisting all generated embeddings to S3. This allows subsequent calls to optionally leverage the cached embeddings, avoiding additional and unecessary cost of re-embedding.

Install

pip install langchain-s3-cached-embeddings

Usage

from langchain_s3_text_loaders import S3DirectoryLoader

   embeddings = S3EmbeddingsConduit(
        embeddings=OpenAIEmbeddings(model=model), # required
        bucket="my-embeddings-bucket", # required
        prefix="my-optional-prefix",
        filenaming_function=lamdba x: f"{x[0]}-{x[1].embedding.txt"}, # optional function to name your embedding file
        cache_behavior=CacheBehavior.NO_CACHE, # set to #CacheBehavior.ONLY_CACHE to use previously cached embeddings
    )
