When KV Cache Reuse Fails in Multi-Agent Systems: Cross-Candidate Interaction is Crucial for LLM Judges

arXiv — cs.CLWednesday, January 14, 2026 at 5:00:00 AM
  • Recent research highlights that while KV cache reuse can enhance efficiency in multi-agent large language model (LLM) systems, it can negatively impact the performance of LLM judges, leading to inconsistent selection behaviors despite stable end-task accuracy.
  • This finding is significant as it underscores the need for careful consideration of cross-candidate interactions in LLM systems, which are crucial for maintaining the integrity of the judging process in response generation.
  • The implications of this study resonate with ongoing discussions about the reliability of AI systems, particularly in multi-agent frameworks where communication and interaction dynamics play a pivotal role in overall performance.

SwiftMem: Fast Agentic Memory via Query-aware Indexing
PositiveArtificial Intelligence
SwiftMem has been introduced as a query-aware agentic memory system designed to enhance the efficiency of large language model (LLM) agents by enabling sub-linear retrieval through specialized indexing techniques. This system addresses the limitations of existing memory frameworks that rely on exhaustive retrieval methods, which can lead to significant latency issues as memory storage expands.
PrivGemo: Privacy-Preserving Dual-Tower Graph Retrieval for Empowering LLM Reasoning with Memory Augmentation
PositiveArtificial Intelligence
PrivGemo has been introduced as a privacy-preserving framework designed for knowledge graph (KG)-grounded reasoning, addressing the risks associated with using private KGs in large language models (LLMs). This dual-tower architecture maintains local knowledge while allowing remote reasoning through an anonymized interface, effectively mitigating semantic and structural exposure.
STO-RL: Offline RL under Sparse Rewards via LLM-Guided Subgoal Temporal Order
PositiveArtificial Intelligence
A new offline reinforcement learning (RL) framework named STO-RL has been proposed to enhance policy learning from pre-collected datasets, particularly in long-horizon tasks with sparse rewards. By utilizing large language models (LLMs) to generate temporally ordered subgoal sequences, STO-RL aims to improve the efficiency of reward shaping and policy optimization.
Surgical Refusal Ablation: Disentangling Safety from Intelligence via Concept-Guided Spectral Cleaning
NeutralArtificial Intelligence
The introduction of Surgical Refusal Ablation (SRA) aims to enhance the safety of language models by refining their refusal capabilities, minimizing collateral damage and distribution drift caused by traditional methods. SRA achieves this by creating a registry of independent Concept Atoms and utilizing ridge-regularized spectral residualization to produce a clean refusal direction.
