ForeSight addresses the critical challenge of early safety detection in large language models by distilling weak initial signals from first-token hidden states into compact, layer-aware risk representations. This approach overcomes limitations of existing methods that either rely on surface tokens or retain redundant information, offering a more efficient framework for forecasting harmful content generation. The research demonstrates superior performance across multiple benchmarks while operating solely on early post-generation states, marking a significant step forward in AI safety mechanisms.
ForeSight: Enhancing Risk Monitoring via Early Safety Signal Distillation
arXiv:2609.13737v1 Announce Type: new Abstract: As large language models (LLMs) are increasingly deployed, the generation of harmful content has become a critical safety concern. Existing safeguards operate at the input, output, or streaming-generation stages, while early-risk methods that rely on surface tokens or output logits may suffer from weak initial signals, and internals-based detectors using dense representations may retain highly entangled and redundant safety-irrelevant information. It therefore remains unclear whether the earliest post-generation hidden states already contain reliable signals about final-response harmfulness. To address this gap, we propose ForeSight, a first-token output-risk forecasting framework that distills weak and redundant early safety signals into compact, layer-aware risk representations. Experiments on five safety benchmarks and two target models demonstrate that ForeSight achieves superior and efficient early-risk forecasting while relying solely on first-token hidden states.
