Qwen3.8-27B can silently corrupt business records
Summary
A forensic evaluation of Qwen3.8-27B reveals three core problems for business workflows: silent rewriting of data due to glitch tokens, a privacy reflex that drops PII in archival tasks while allowing data through in extraction or summary, and the presentation of stale facts as current without knowledge-cutoff caveats. The report provides evidence across tasks, compares against control models, and discusses mitigations and guardrails for deployment.
