What is Cloudflare Workers AI + Vectorize?

AI applications often need to find things by meaning rather than exact words, and using a machine learning model to search a large dataset can be slow and expensive. A vector database helps by storing data as lists of numbers (vectors) and returning the stored items nearest to a query, which supports semantic search, recommendations and anomaly detection. Cloudflare Workers AI lets developers run machine learning models on GPUs on Cloudflare's global network without the developer having to set up or manage servers. Vectorize is Cloudflare's vector database: a developer turns data into vector embeddings (the lists of numbers that represent each item) with a model, stores them in Vectorize, and queries it to get back the most similar items. Cloudflare describes Vectorize as globally distributed and built for use with Cloudflare Workers.
