Glossary

The words SwiftTune uses for the parts of an AI application, defined once and linked from everywhere else.

Flow
A flow is the unit SwiftTune composes and deploys: a directed graph of blocks whose connections carry data from a trigger to a response.
Block
A block is one node of a flow: a named, configurable step that takes typed input on its input ports and produces typed output on its output ports.
Port
A port is a named, typed connection point on a block.
Deployment
A deployment is one published version of a flow: the Worker that Cloudflare runs, the URL it answers on, and the record of which flow version it came from.
Edge
The edge is the network of data centres a request reaches first, close to the person making it.
Workers AI
Workers AI is Cloudflare’s inference service: open models hosted on the same network the rest of a flow runs on, called through a binding instead of over the public internet.
AI Gateway
AI Gateway is Cloudflare’s proxy in front of model providers.
Vectorize
Vectorize is Cloudflare’s vector database: it stores embeddings and answers similarity queries over them.
Retrieval-augmented generation (RAG)
Retrieval-augmented generation is the pattern of answering a question by first retrieving relevant documents and then asking a model to answer using them.
Evaluation
An evaluation scores a flow against a fixed dataset of inputs and expected outcomes, so a change can be compared with the version before it.
EU data residency
EU data residency means the durable copies of your data are held in data centres inside the European Union.
Bring your own account
Bringing your own account means the flows you publish run in your Cloudflare account rather than in a pool the vendor owns.
