豫冠薰衣草疤痕精华素

Apparently a fake “brand” string from cosmetic spam-marketing text. Listed by the Zhihu community as a Kimi dirty token.

"豫冠薰衣草疤痕精华素"

Observed behaviors

• 01A fingerprint token from the Zhihu community's “dirty-token” method for detecting watered-down LLM APIs: send it as input to the API under test — refusals, gibberish, or abnormal output suggest the service is actually running Kimi.zhihu.com
• 02In ztracer's tests, Kimi v2.6 repeated it as a medical-ad brand string (in the “【brand】治疗…” advertorial format) — unrelated to the original token in semantics, domain and text; a textbook cross-domain hallucinated substitution that the report calls an “extremely severe” dirty-token symptom.ztracer.github.io
