FAQPage Schema
How do I store embeddings locally for RAG without relying on hosted services?

Store embeddings locally for RAG using an open-source vector database like Chroma. It provides persistent storage and metadata filtering, enabling self-hosted semantic search for AI applications without relying on external hosted services.

What is the best way to add a memory layer to AI agents for retrieving context?

Add a memory layer to AI agents using a local vector database. It stores document embeddings and metadata, allowing agents to perform fast semantic search and retrieve relevant context quickly during interactive tasks.

Can I use Chroma with LangChain or LlamaIndex for self-hosted deployments?

Yes, you can use Chroma with LangChain and LlamaIndex. It offers framework integrations specifically designed for building on-device or self-hosted RAG workflows and memory-powered AI applications.

Does this open-source vector database support metadata-based filtering?

Yes, this open-source vector database supports metadata-based filtering. You can store embeddings alongside metadata and use it to filter results, enabling precise semantic search for RAG workflows in production environments.

How do I set up a local vector store for semantic search in notebooks?

Set up a local vector store for semantic search in notebooks by installing the chromadb package, creating a collection, and storing embeddings. It provides a simple 4-function API for persistent storage across environments.
