Researchers propose efficient LLM classification probes to reduce latency and VRAM

Researchers have developed a method to integrate classification tasks, such as safety checks, directly into the forward pass of large language models (LLMs). This approach uses lightweight probes trained on the LLM's internal states, eliminating the need for separate classification models. The technique, which summarizes token and layer information, has shown competitive performance against larger, dedicated models while maintaining near-serving latency and reducing VRAM usage. Experiments across various LLM architectures, including Llama-3.2-3B and GPT-OSS-20B, demonstrate the generalizability of this efficient classification strategy. AI
