# AI记忆系统引入生物衰减机制，召回率提升52%

传统RAG系统因记忆无限累积导致上下文污染和推理退化。新系统引入类似生物记忆的衰减机制，52%关键信息留存率显著提升检索效率。该实现动态删除过时数据，降低50% token成本，有效防止AI模型在长任务中迷失。开发者可将其集成到现有代理框架，优化知识管理流程。

## English Version

**AI Memory System with Biological Decay Boosts Recall to 52%**

Traditional RAG systems suffer from infinite memory accumulation causing context pollution and degraded reasoning. This new system implements biological-like memory decay, achieving 52% key information retention for significantly improved retrieval efficiency. It dynamically removes outdated data, cutting token costs by 50% and preventing AI agents from getting lost in long tasks. Developers can integrate it into existing frameworks to optimize knowledge management.
