Can You Trust an AI's Summary?

A listener asks a sharp question: do dedicated text compaction models exist, and how would you ever know the summary didn't drop something critical? This episode explores the surprising gap between research compressors and production coding agents — from LLMLingua and RECOMP to the deeper fidelity problem that keeps engineers up at night. We unpack why token-level pruning breaks on agent transcripts, why prompt-cache economics invert the cost argument, and why "the agent kept working" is a dangerously flawed signal for summary quality.
