Dedicated vector databases needed only for over 1M vectors, says IBM Tech

By PulseAugur Editorial · [1 sources] ·

A discussion on the necessity of dedicated vector databases highlights that while long-context and agent-based search can handle many scenarios, embeddings become crucial when a "semantic gap" exists. The general guideline suggests considering a dedicated vector database only when dealing with over a million vectors. AI
