Two agents read the same document under different instructions. Their cached representations are not necessarily interchangeable, even though the source text is identical.
LatentRemedy's October 13 paper studies severe degradation from non-prefix cache reuse under conflicting tasks. Its remedy adds a small learned set of task-conditioned latent tokens after the reused block, trained through full-prefill distillation. Read the research paper.
Reuse carries an interpretation
The donor's prefix helped shape the cached document. The receiver must work with a state formed under someone else's question, rather than fresh text interpreted under its own.
The proposed tokens help bridge that mismatch without recomputing the shared block. Their training and compatibility requirements still count; this is not an arbitrary plug-in repair for every pair of agents.
Evaluate contradictory task instructions and compare with exact full prefill. Sharing between similarly prompted agents can hide the cases where interpretation matters most.
The finding changes how to describe shared context infrastructure. A cache is not simply a faster document. It is the result of a computation with a history. Efficient multi-agent serving needs to preserve or deliberately adapt that history, rather than assuming common words imply common usable state.
