The record

Use cases: It supports semantic search, recommendations, classification, anomaly detection, and providing context to large language models.
Embeddings: Vectors can come from Workers AI models or be supplied from platforms such as OpenAI.
Cloudflare integrations: Vector search results can reference images in R2, documents in KV, and user profiles in D1.
Worker access: Workers connect to an index through a Vectorize binding configured in Wrangler or the Cloudflare dashboard.
API access: Vectorize supports a REST API for operating on indexes, including inserting and querying vectors.
Capacity: An index can contain up to 20 million vectors, with a maximum of 1,536 dimensions per vector at 32 bit precision.
Query limits: Queries can return up to 50 results with values or metadata, or up to 100 results without them.
Billing: Vectorize does not bill for CPU, memory, active index hours, or the number of indexes, and does not charge for data transfer or egress.
Support: Cloudflare directs Vectorize users to its #vectorize Discord channel for questions, discussion, bug reports, and feedback.
Access security: Cloudflare describes Workers bindings as a capability and API, with the underlying secret never exposed to Worker code.
