A user identified the mysterious model 'Ox Alpha' as a Zhipu AI model by triggering a Java stack trace with a malformed request. Evidence includes the internal class name ChatCompletionRequest and the API route paas/v4/chat, which matches Zhipu's documented paths. The author states this evidence comes from the serving layer with 0.98 confidence, rather than being a fingerprint guess based on tokenizers.
