REVEAL: Reverse Engineering Agentic Latents from Frontier-Model Traces

Inspired by protocol reverse engineering, we introduce $Agentic Latents$, comprising anchored states and dynamic profiles of feedback--response cycles elicited by replay in the target model.

Key points

  • Frontier LLM agents perform complex interactive tasks, but their inference costs motivate transferring their experience to smaller open-source agents.
  • We study how textual frontier-model trajectories can provide reusable local controls for a frozen agent.
  • Our training-free framework, $REVEAL$ ($REV$erse $E$ngineering $A$gentic $L$atents), uses these profiles and trajectory outcomes to match and select local events from successful and failed rollouts of the same task and source model.
  • Representation analyses and behavioral case studies support reusing frontier-model experience as local activation control.
