arXiv:2604.22565v2 Announce Type: replace Abstract: Large Language Models (LLMs) can reason well, yet often miss decisive evidence when it is buried in long, noisy contexts. We introduce HiLight, an Evidence Emphasis framework that decouples evidence selection from reasoning for frozen LLM solvers. HiLight avoids compressing or rewriting the input, which can discard or distort evidence, by training a lightweight Emphasis Actor to insert minimal highlight tags around pivotal spans in the unaltered context. A frozen Solver then performs downstream reasoning on the emphasized input. We cast highl
The proliferation of Large Language Models (LLMs) and the increasing complexity of real-world inputs necessitate innovative approaches to improve their reasoning capabilities without costly retraining.
This development addresses a key limitation of LLMs in handling long, noisy contexts, potentially making them more reliable and efficient for a broader range of applications.
The ability to 'highlight' crucial evidence for frozen LLMs introduces a new paradigm for enhancing their performance, shifting the focus from internal model modifications to external input pre-processing.

LLMs become more effective at parsing and responding to complex documents and conversations.
The cost and computational overhead of deploying highly effective LLM-based systems may decrease due to less reliance on full model fine-tuning.
This could accelerate the development of more sophisticated AI agents that can parse and act upon vast amounts of unstructured information with greater precision.
