Pinecone is closed source and only available as a SaaS service. Milvus and us have more overlap, we’re focused on the embeddings workflow like versioning and using embedding with other features. Milvus is entirely focused on nearest neighbor operations.

Faiss is solving the approximate nearest neighbor problem, not the storage problem. It’s not a database, it’s an index. We use a lightweight version of Faiss (HNSWLIB) to index embeddings in Embeddinghub.
