Cloudflare launches Auto Router public beta in AI Gateway to rate requests by stakes and other metrics

Cloudflare published Auto Router in public beta via AI Gateway: a two-stage router that builds a candidate model pool then runs a multi-head classifier on Workers AI to assign probabilities across 14 task categories and score requests 1–5 on complexity, ambiguity, stakes and context dependence, using only the newest turns (up to 8 KiB). The router combines those scores with benchmark results (quoted formula: "utility = expected quality - adaptive cost penalty"), exposes routing headers for auditability, supports per-request allowed-models headers, is free in beta, and currently lacks WebSocket support.
