Researchers introduce HORMA, a hierarchical memory system for LLM agents that organizes experience into structured hierarchies with linked summaries and raw trajectories. The system achieves 22% token efficiency on long tasks while maintaining performance, addressing critical limitations in how language model agents manage working memory for multi-step reasoning.
Researchers introduce Reasoning in Memory (RiM), a novel method that enables large language models to perform internal reasoning using fixed memory blocks instead of generating intermediate tokens. The approach matches or exceeds existing reasoning methods while being more compute-efficient, as memory blocks process in a single forward pass rather than through autoregressive generation.
Researchers have developed a physics-driven AI system called Intrinsic Plasticity Network (IPNet) that uses magnetic tunnel junctions to create human-like working memory. The system demonstrates 18x error reduction in dynamic vision tasks while reducing memory-energy overhead by over 90,000x compared to traditional digital AI systems.
Researchers introduce HGMem, a hypergraph-based working memory system that enhances multi-step retrieval-augmented generation (RAG) for large language models by modeling complex relational dependencies among facts. Unlike traditional RAG systems that treat memory as passive storage, HGMem dynamically structures information as interconnected high-order relationships, demonstrating improved performance on global sense-making benchmarks requiring complex reasoning across extended contexts.
Researchers discovered that large language models exhibit working memory limitations similar to humans, encoding multiple memory items in entangled representations that require interference control rather than direct retrieval. This finding reveals a shared computational constraint between biological and artificial systems, suggesting that working memory capacity may be a fundamental bottleneck in intelligent systems rather than a limitation unique to biological brains.
