A server for AI image generation. Provides a backend service over multiple APIs (GRPC and REST) for use by one or more frontends.

In particular, aims to be a local, open source implementation of the Stability AI APIs, but also includes a lot of useful extensions.

Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

First stanza of The Second Coming by William Butler Yeats

AI is a force for disruption. But I am not so pesimistic as Yeats - the center will hold, even in the widening gyre.
