FAQPage Schema
How do I set up a local vector database for storing AI embeddings?

To set up a local vector database for AI embeddings, you can install the chromadb package and initialize a collection to begin storing embeddings and metadata locally without relying on external services.

What is the best way to add memory to AI applications using semantic search?

The best way to add memory to AI applications using semantic search is by using an open-source vector database to store and retrieve embeddings efficiently with metadata filtering.

Does Chroma work with LangChain and LlamaIndex for RAG workflows?

Yes, Chroma works seamlessly with LangChain and LlamaIndex, providing local persistent storage for embeddings and metadata to enable fast document retrieval within RAG workflows.

Can I filter embeddings by metadata when doing similarity search?

Yes, you can filter embeddings by metadata during similarity search. Chroma provides fast similarity search, document retrieval, and metadata filtering across notebooks and production pipelines.

Do I need an external service to run a vector database for experiments?

No, you do not need an external service to run a vector database for experiments. Chroma provides an open-source, self-hosted vector store that enables fast similarity search locally.

What limitations exist when using an open-source vector database for AI memory?

Limitations of an open-source vector database for AI memory include the requirement to self-host and manage the infrastructure, though Chroma mitigates this with a simple four-function API and language-agnostic client support.
