Decision-Centric Design for LLM Systems

Researchers propose a new framework that separates decision-relevant signals from execution policies in LLM systems to improve transparency and control. This decision-centric approach addresses the 'black box' nature of AI decision-making, enabling better performance and modular diagnosability.

Title:Decision-Centric Design for LLM Systems

View PDF HTML (experimental)Abstract:LLM systems must make control decisions in addition to generating outputs: whether to answer, clarify, retrieve, call tools, repair, or escalate. In many current architectures, these decisions remain implicit within generation, entangling assessment and action in a single model call and making failures hard to inspect, constrain, or repair. We propose a decision-centric framework that separates decision-relevant signals from the policy that maps them to actions, turning control into an explicit and inspectable layer of the system. This separation supports attribution of failures to signal estimation, decision policy, or execution, and enables modular improvement of each component. It unifies familiar single-step settings such as routing and adaptive inference, and extends naturally to sequential settings in which actions alter the information available before acting. Across three controlled experiments, the framework reduces futile actions, improves task success, and reveals interpretable failure modes. More broadly, it offers a general architectural principle for building more reliable, controllable, and diagnosable LLM systems.

Teaching LLMs to Update Beliefs for Efficient Long-Horizon Interaction

As LLMs tackle longer tasks, retaining complete interaction histories becomes contextually and computationally expensive. The ABBEL framework addresses this by isolating summaries into natural-language 'belief states' and supervising them via belief grading, recovering accuracy while significantly cutting memory usage.

Benchmarking Large Language Models on Multi-Sensor Physical Hazard Assessment

A new benchmark evaluates five leading large language models on multi-sensor physical hazard assessments, revealing a critical vulnerability when evaluating combined sensor risks below individual thresholds. Despite near-perfect accuracy on single-sensor breaches, all models failed to issue precautionary signals for multi-sensor hazards.
