On my never-ending quest to find the best embeddings model, I was intrigued to come across Voyage-Context-3 by MongoDB and was excited to give it a try.

This template implements the embedding model on a Arxiv research paper and stores the results in a Vector store. It was only fitting to use Mongo Atlas from the same parent company. This template also includes a RAG-based Q&A agent which taps into the vector store as a test to helps qualify if the embeddings are any good and if this is even noticeable.

How it works

This template is split into 2 parts. The first part being the import of a research document which is then chunked and embedded into our vector store. The second part builds a RAG-based Q&A agent to test the vector store retrieval on the research paper.

Read the steps for more details.

How to use

  • First ensure you create a Voyage account voyageai.com and a MongoDB database ready.
  • Start with Step 1 and fill in the "Set Variables" node and Click on the Manual Execute Trigger. This will take care of populating the vector store with the research paper.
  • To use the Q&A agent, it is required to publish the workflow to access the public chat interface. This is because "Respond to Chat" works best in this mode and not in editor mode.
  • To use for your own document, edit the "Set Variables" node to define the URL to your own document.
  • This embeddings approach should work best on larger documents.

Requirements

  • Voyageai.com account for embeddings. You may need to add credit to get a reasonable RPM for this workflow.
  • MongoDB database either self-hosted or online at https://www.mongodb.com.
  • OpenAI account for RAG Q&A agent.

Customising this workflow

  • The Voyage embeddings work with any vector store so feel free to swap out to other such as Qdrant or Pinecone if you're not a fan of MongoDB Atlas.
  • If you're feeling brave, instead of the 3 sequential pages setup I have, why not try the whole document! Fair warning that you may hit memory problems if your instance isn't sufficiently sized - but if it is, go head and share the results!
