SpecGuard: Inference-Time Backdoor Detection For Free
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- SpecGuard detects backdoored language models at inference time by monitoring speculative decoding acceptance rates, adding zero computational overhead.
- Why it matters
- Matters for engineers deploying frequently updated LLMs from third parties where runtime monitoring complements pre-deployment audits.
- Watch out
- Paper is recent preprint; real-world effectiveness against adaptive attackers who know the detection mechanism remains unproven.
