Belief-reality separation lives in routing over a shared value slot in language models

A new paper reveals how large language models separate a character's belief from reality through a value slot and routing mechanism. The research shows two distinct mechanisms: a generic value slot for binding attributed values, and a router that selects which frame (belief or reality) to read from. The slot is filled either directly or via visibility-gated lookback, and the separation resides in routing subspaces rather than the slot itself. These findings hold across architectures and emerge between 3B and 7B parameters.

  • Language models use a value slot and router to separate belief from reality.
  • Two routes fill the slot: direct assertion and visibility-gated derivation.

Graph Feedback Controls Consensus and Clique Formation in Open-Weight Language-Model Populations

This study investigates how the interaction graph structure in multi-agent language model systems affects consensus formation. Using a naming-game protocol, researchers analyzed convention formation in open-weight LM populations (1.1B-32B parameters). They found that homophilous threshold-similarity routing exacerbates fragmentation, while bridge-seeking routing can repair fragmentation when memory is available. In heterogeneous populations, threshold-similarity fails to produce consensus, while state-component and label-disagreement bridges recover consensus. In homogeneous populations, retained history generally promotes consensus, with Qwen2.5-32B reaching stable consensus in all retained-history settings.

  • Interaction graph structure significantly impacts consensus in multi-agent LM systems.
  • Homophilous threshold-similarity routing exacerbates fragmentation; bridge-seeking routing can repair it when memory is available.
