New framework quantifies perturbation propagation in compound AI systems

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced QUIVER, a new formal framework designed to measure how perturbations propagate through compound AI systems that chain multiple large language model calls. This framework quantifies sensitivity by classifying edges as amplifiers or absorbers and decomposes variation into value drift, structural path divergence, and iteration count divergence. QUIVER also identifies bifurcation thresholds, the minimum perturbation causing structural execution path changes, and assesses distribution faithfulness. Validation on enterprise and public pipelines demonstrated QUIVER's ability to reveal distinct sensitivity profiles and predict nodes prone to trajectory bifurcation. AI

IMPACT Provides a method to analyze and improve the robustness of complex, multi-stage AI systems.

    QUIVER: A Formal Framework for Quantifying Perturbation Propagation and Bifurcation in Compound AI Systems

    arXiv:2605.23956v1 Announce Type: new Abstract: Compound AI systems that chain multiple LLM calls into directed computation graphs are now the dominant architecture for production AI. Although these architectures leverage heterogeneous nodes with mixed-mode outputs, no existing f…
