- 发生了什么
- SpecGuard detects backdoored language models at inference time by monitoring speculative decoding acceptance rates, adding zero computational overhead.
- 为何重要
- Matters for engineers deploying frequently updated LLMs from third parties where runtime monitoring complements pre-deployment audits.
- 注意
- Paper is recent preprint; real-world effectiveness against adaptive attackers who know the detection mechanism remains unproven.
