Fingerprint test suggests Union Alpha is a router layer built on GLM-family models

By serving a controlled image_url, the author captured the backend's image fetch: egress via Deep Infra and AWS with a vLLM build UA, pointing to GLM-5.3-Flash support.

🔥最新发现:Union Alpha 可能不是单一新模型,而更像路由/拼装层(router),底层可能混了包括智普 GLM 系在内的模型! Can演示:给匿名模型发一张“会打电话回家”的图片,就能把托管方从 Deep Infra / AWS + vLLM 这条线上揪出来。​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ 测试发现: 🔹不传 base64,改发自己控制的 image_url
🔹模型后端会主动来拉图,IP / ASN / UA 全部落盘
🔹第一跳:38.101.151.58,犹他 Bluffdale,AS16581,Deep Infra
🔹第二跳:18.224.53.50,AS16509,AWS 🔹UA 直接写着 vLLM/0.1.dev20051+g487ecf187
🔹这个 commit 正是给 GLM-5.3-Flash 加支持的开发构建
🔹有中间层时可能先抓图再转 base64,指纹会偏,但这次两边都打到了真实出口 结论先记一笔:托管像 Deep Infra,推理栈像 vLLM,底层很像 GLM 线;更像 router,不像一块全新黑盒。 #UnionAlpha #StealthModel #DeepInfra #vLLM #GLM53Flash #LLMFingerprint #OpenRouter #Zai #智普
