// The Efficiency Frontier //

Cool paper on context management.

As agents reuse the same documents and histories across many turns， the cheapest context strategy is not fixed. This work describes a principled rule for picking one per deployment instead of defaulting to whatever topped a benchmark in isolation.

Retrieval and compression methods are almost always benchmarked on accuracy and cost separately， so you never learn when one actually beats another under real load.

The Efficiency Frontier models context strategy selection as a single cost-performance problem， with a log-utility term for diminishing returns from extra context and a reuse parameter N that amortizes preprocessing across repeated queries.
