Ships with the build. The reference for this surface is published with the build each tester receives, so it matches the binary in their hands rather than a page written ahead of it. What is on this page is the part we can state from here.
CLI
aisl drives the same runtime from a terminal: models, chat, document collections, status and diagnostics.
The command reference is published with the build. That is deliberate. A flag that changed between two builds would make a page here wrong for whoever read it first, and a documented command that does not exist costs a reader an afternoon, so the reference travels with the binary it describes.
What is stable enough to state here: the CLI and the local API talk to the same runtime, on the same port, with the same locally generated token, and anything the CLI can reach the API can reach too. See the local API.
