EMBER: Efficient Memory via Budgeted Evidence Retention for Long-Horizon Agents

arXiv:2606.05894v1 Announce Type: new Abstract: Long-horizon agents can archive large histories, but future answers still incur retrieval, rereading, and context costs. When retained memory misses answer-relevant evidence, the system must return to larger portions of the raw history. We study budgeted evidence survival: before the query is known, which source evidence should be retained so that it remains recoverable and usable under a fixed retained source-evidence token budget? We instantiate this setting as Budgeted Pre-Query Retention, where memory is written during ingestion and later rea

Why this matters
Why now

The increasing complexity and long-horizon requirements of AI agents necessitate more efficient and intelligent memory management solutions.

Why it’s important

This development addresses a critical bottleneck in AI agent performance, enabling more sophisticated and less resource-intensive autonomous systems.

What changes

AI agents will be able to operate with much longer and more relevant memory contexts, reducing computational overhead and improving accuracy for complex tasks.
