Cloudflare 发布 Auto Router 公测：按请求风险与复杂度自动选模型
原标题：Cloudflare’s Auto Router Rates Each Request for Stakes, from the Most Recent Turns
AI 摘要
Cloudflare 通过 AI Gateway 发布 Auto Router 公测版，用户将模型设为 cloudflare/auto 后，由分类器按请求选择模型。路由分两阶段：先构建候选池并过滤不支持的请求格式，再用多任务分类模型在边缘 GPU 上按 14 类任务和复杂度、歧义、风险、上下文依赖四个维度打分。Cloudflare 公布的基准显示，可靠性提升 10 点、花费约为三分之一，但从业者指出仅依据最近轮次判断风险可能低估长会话中的关键操作，且路由权重需手动更新。

Cloudflare recently released Auto Router in public beta through AI Gateway. Set the model to cloudflare/auto, and a classifier picks one per request. The most useful thing in the announcement is a benchmark where Cloudflare’s own router loses. Routing runs in two stages. AI Gateway first builds a candidate pool, filtering models that cannot serve the request format and applying credentials, billing configuration, access control, and spend limits. A multi-head classification model then runs on Wo
