🛠️ Semantic Overlays – an NX bit for LLM prompt injection (live demo)
Summary
Semantic Overlays is a method for steering LLMs using small trained adapters on a frozen model to change how it perceives context. It aims to mitigate prompt injection, upgrading a Qwen-3.5-9B model to state-of-the-art scores on prompt injection benchmarks.
Why it’s interesting
It introduces a novel NX bit-style mitigation technique for LLM prompt injection using small trained adapters.
