Rare Event Analysis of Large Language Models (opens in new tab)

arXiv:2602.06791v1 Announce Type: cross Abstract: Being probabilistic models, during inference large language models (LLMs) display rare events: behaviour that is far from typical but highly significant. By definition all rare events are hard to see, but the enormous scale of LLM usage means that events completely unobserved during development are likely to become prominent in deployment. Here we present an end-to-end framework for the systematic analysis of rare events in LLMs. We provide a...
