ElasticMem: Latent Memory as a Learnable Resource for LLM Agents

arXiv:2605.30690v1 Announce Type: new Abstract: Long-term memory is essential for LLM agents to reason coherently across extended interactions, personalize responses, and reuse past experience. However, existing memory-augmented methods typically treat memory as a fixed resource: text-space approaches concatenate retrieved memories into the context window, causing substantial token overhead and sensitivity to noisy evidence, while latent-space approaches reduce textual cost but still rely on rigid retrieval or fixed-capacity memory interfaces. This creates a mismatch between query-dependent me

Why this matters
Why now

The paper addresses a critical limitation in current LLM agent architectures regarding long-term memory and coherent reasoning, which is increasingly vital as LLM applications become more complex and require extended interactions.

Why it’s important

This research introduces a novel approach to memory management for LLM agents, potentially enabling more personalized, efficient, and robust AI systems capable of learning and adapting over time without excessive computational overhead.

What changes

The shift from fixed-resource memory to a learnable, elastic memory system could significantly enhance the autonomy and reasoning capabilities of AI agents, making them more adaptable and less prone to 'forgetting' past interactions.
