FOCUS: Training-Free Decision-Preserving Context Compression for LLM Agents

Shantanu Dixit, Anson Bastos, Xuchao Zhang et al. · 2026

LLM agents accumulate interaction histories that grow linearly with task length, causing quadratic inference cost scaling and performance degradation from attention dilution. Existing context-compression methods learn what to discard offline: by contrastively optimizing guidelines, distilling compressors, or training c …

PSD: Pseudo Self-Distillation of Memory Representation Capabilities for LLM Agents

Pirzada Suhail, Menglin Xia, Xuchao Zhang et al. · 2026

Memory systems are becoming a core component of LLM agents, but constructing and maintaining memory remains expensive because it relies on repeated calls to large proprietary language models. This cost creates a major barrier to deploying memory-enhanced agents at scale. In this paper, we present Pseudo Self-Distillati …
