The zero-exposure default: one local AI server for everything on your machine
The default AI Server posture is loopback-only: it binds 127.0.0.1, needs no keys or licence, and every app on the machine shares one model in memory. Worth understanding before anything is networked.
One AI Server on a single Windows, macOS, or Linux machine, serving only that machine, is the configuration every AI Suite desktop app creates for itself automatically [1]. Running it deliberately shows what that default actually is. The daemon binds 127.0.0.1 only, so nothing else on the network can reach it; it needs no keys and no licence, because loopback serving is free; and every app on the machine shares the one daemon, which means one model in memory rather than a copy per app [1].
Nothing on the network can reach it
Loopback is not a firewall rule you might forget to add. The socket is bound to the local interface, so the endpoint does not exist to any other machine [2]. That is the default posture worth understanding before anything is deliberately networked: know what runs locally, then decide what to expose.
One daemon, one model in memory
Because apps on the same machine discover the daemon automatically through its server.lock file, opening a second app does not load a second copy of the model [1]. The chat app, the notes app, and the PDF reader all attach to the same running server and the same warm model.
Stub for CI, real for work
The stub engine starts instantly with no downloads, which suits CI agents that need a local AI endpoint for tests; the real engine downloads a model on first use for actual inference [2]. A health check and an OpenAI-shaped chat completion confirm it is up. The built-in dashboard shows the mode badge and the request you just made, no key required on the same machine.
Nothing to configure
There is nothing else to set: no keys, no licence, no network policy for the single-machine case [1]. It runs on the laptop you already own, fully offline. When you are ready to serve more than one machine, the same daemon binds the LAN behind a key.
