New WMF-AM benchmark probes LLM working memory and cumulative state tracking

Researchers have developed a new evaluation method called Working Memory Fidelity-Active Manipulation (WMF-AM) to specifically test the cumulative state tracking abilities of large language models. This probe measures how well models can maintain and update intermediate results across sequential operations within a single query, without relying on external tools like scratchpads. The WMF-AM method is designed to be lightweight and recalibratable, allowing for a more precise characterization of model performance degradation under cumulative load. AI

IMPACT Introduces a new diagnostic tool to better understand LLM limitations in maintaining context during complex tasks.

    WMF-AM: Probing LLM Working Memory via Depth-Parameterized Cumulative State Tracking

    arXiv:2603.27343v2 Announce Type: replace Abstract: Existing large language models (LLMs) evaluations use fixed-difficulty benchmarks that cannot adapt as models improve, and rarely isolate specific cognitive processes. We introduce Working Memory Fidelity-Active Manipulation (WM…
