Much has been said about vector databases and their implications in the AI model space. Vector databases are specialised systems for storing, indexing and efficiently retrieving high-dimensional vectors used for machine learning and data analytics. As its popularity increases, so does the number of vector database courses available online.
Vector databases are also essential for supporting large language models and generative AI applications by providing fast and accurate similarity search, scalability, and metadata storage and filtering capabilities. Unlike regular databases that are designed for organised information, vector databases are really good at handling complex sets of numbers, usually representing features from things like images, texts, or different types of data.
The selection of a vector database for generative AI applications is contingent upon the particular needs and features of the generated vectors. Here are some of the vector database options for generative AI applications.
