Similarity search

A vector databases enables fast, efficient similarity searches on and across any modalities, such as text or images, as well as their combinations. Vector database' similarity search capabilities can be used for other complex use cases, such as recommendation systems in classical machine learning applications.

LLMs and search

Vector databases and LLMs go together like cookies and milk!

Vector databases help to address some of large language models (LLMs) limitations, such as hallucinations, by helping to retrieve the relevant information to provide to the LLM as a part of its input.
