Researchers have identified specific attention heads within language models that are responsible for recognizing network infrastructure information, such as hostnames and IP addresses. Through causal ablation screening, they found that a small subset of heads, typically 1 to 9 out of hundreds, can accurately detect this information with near-perfect accuracy. The study also revealed that the concentration of this responsibility varies by model, with some models showing a single neuron responsible, while others distribute the task across an entire head. AI
