MosaicML offers a managed inference service. You can either use a variety of open-source models, or deploy your own.
This example goes over how to use LangChain to interact with MosaicML Inference for text embedding.
from getpass import getpass
MOSAICML_API_TOKEN = getpass()
import os
os.environ["MOSAICML_API_TOKEN"] = MOSAICML_API_TOKEN
from langchain_community.embeddings import MosaicMLInstructorEmbeddings
embeddings = MosaicMLInstructorEmbeddings(
query_instruction="Represent the query for retrieval: "
)
query_text = "This is a test query."
query_result = embeddings.embed_query(query_text)
document_text = "This is a test document."
document_result = embeddings.embed_documents([document_text])
import numpy as np
query_numpy = np.array(query_result)
document_numpy = np.array(document_result[0])
similarity = np.dot(query_numpy, document_numpy) / (
np.linalg.norm(query_numpy) * np.linalg.norm(document_numpy)
)
print(f"Cosine similarity between document and query: {similarity}")
