做AI智能体开发的团队终于有了解决记忆错配问题的方案——Mem-π 让智能体学会“按需生成”而非“死板检索”，在复杂任务中效果显著，建议研究记忆增强的开发者点开看看。
Mem-π 是一种新型自适应记忆框架，它让大语言模型智能体在需要时动态生成指导，而不是从外部存储中检索静态条目。该框架使用独立的语言或视觉语言模型，基于当前上下文决定是否生成以及生成什么指导，并通过决策-内容解耦的强化学习目标进行训练。在网页导航、终端工具使用和文本交互等基准测试中，Mem-π 相比检索式记忆和之前强化学习优化的基线方法表现更优，在网页导航任务上实现了超过30%的相对提升。
Mem-$π$: Adaptive Memory through Learning When and What to Generate
We present Mem-$π$, a framework for adaptive memory in large language model (LLM) agents, where useful guidance is generated on demand rather than retrieved from external memory stores. Existing memory-augmented agents typically rely on similarity-based retrieval from episodic memory banks or skill libraries, returning static entries that often misalign with the current context. In contrast, Mem-$π$ uses a dedicated language or vision-language model with its own parameters, separate from the downstream agent, to generate context-specific guidance for complex tasks. Conditioned on the current agent context, the model jointly decides when to produce guidance and what guidance to produce. We train it with a decision-content decoupled reinforcement learning (RL) objective, enabling it to abstain when generation would not help and otherwise produce concise, useful guidance. Across diverse agentic benchmarks spanning web navigation, terminal-based tool use, and text-based embodied interaction, Mem-$π$ consistently outperforms retrieval-based and prior RL-optimized memory baselines, achieving over 30% relative improvement on web navigation tasks.
