New protocol reveals semantic drift in unified AI models

A new research paper introduces the Semantic Drift Protocol (SDP), a method to evaluate the consistency of unified AI models that handle both image-to-text and text-to-image tasks. The SDP simulates a "Telephone Game" by alternating between understanding and generation over multiple steps to measure how much semantic information is lost. This protocol reveals significant semantic drift in models that perform well on isolated benchmarks, highlighting failure modes not captured by traditional evaluations. The research proposes new metrics, Mean Cumulative Drift (MCD) and Multi-Generation GenEval (MGG), and introduces a benchmark dataset to better assess the reliability of these unified models. AI

IMPACT This research highlights critical reliability issues in unified AI models, potentially impacting their deployment in applications requiring consistent multi-modal understanding and generation.

    The Telephone Game: Evaluating Semantic Drift in Unified Models

    arXiv:2509.04438v3 Announce Type: replace-cross Abstract: Unified models (UMs) combine visual understanding (I2T) and generation (T2I) in a single framework. We focus on T2I and I2T, where cross-consistency---what a model understands, it should be able to generate---is a promise …
