New OS Kernel Primitive Enhances LLM Safety Checks

A new kernel-level operation called ProbeLogits has been developed for AI-native operating systems, allowing them to directly read an LLM's logit distribution before token generation. This primitive enables the OS to classify agent actions as safe or dangerous without requiring a separate guard model, significantly reducing computational overhead. Evaluations on models like Qwen2.5-7B, Llama-3-8B, and Mistral-7B demonstrated high block rates on benchmarks such as HarmBench and ToxicChat, achieving performance comparable to or better than existing guard models like Llama Guard 3, while operating much faster.
