LAM: Efficient Lossy Agent Memory Framework With A Retrieval-Score Error Bound

Baixi Sun, Le Chen, Anjir Ahmed Chowdhury +10

Agent memory grows as agents read inputs, reason, and call tools. Longer histories increase inference cost and eventually exceed the context window. LLM-based summarization reduces…
