How fudengming/astrbot-t2irouter works

AstrBot T2I Router is a Go HTTP router that selects the first reachable configured text-to-image backend and keeps generated-image lookups pinned to that backend. The principal flow is generation request → backend selection → forwarding or redirect → ID binding → later data lookup and redirect. In-memory bindings expire by TTL and are also cleaned in batches. The source excerpt is partial, so some relationships below rely on the README’s explicit workflow description rather than inspected implementation details.
