- Ce qui s'est passé
- UniMem proposes a self-routing memory framework for LLM agents that balances episodic retrieval and parametric consolidation without explicit task boundaries.
- Pourquoi ça compte
- Matters for engineers building LLM systems that handle continuous task streams where tasks lack clear boundaries and patterns recur unpredictably.
- Vigilance
- Paper is recent preprint with no indication of open-source release, code availability, or reproducibility details yet confirmed.

Abstract: Memory is essential for LLM agents to accumulate task experience and reuse task-specific execution strategies. However, real-world deployment over boundary-agnostic and evolving task streams exposes a fundamental stability-plasticity dilemma. External retrieval-based memory can rapidly absorb new evidence, but it often fails to internalize recurring execution patterns and incurs inference-time retrieval overhead. Parametric memory enables stable and efficient execution once learned, but typically relies on explicit task boundaries and fixed parameter budgets. Inspired by the human brain, which balances plasticity and stability through complementary episodic storage and gradual consolidation, we propose UniMem, a self-routing framework for autonomous memory management. UniMem uses learnable routing tokens as memory controllers, enabling adapt
