New model reveals hidden anchors in multi-agent LLM deliberation

Researchers have developed a new model for multi-agent LLM deliberation, which mimics human decision-making by incorporating a hidden internal belief, or 'anchor,' for each agent. This anchor continuously influences an agent's opinion, independent of its neighbors. The study demonstrates that this anchor can be identified solely from the deliberation process and explains how an agent's confidence can surpass initial levels, moving beyond the constraints of classical consensus models. A method to test the anchor's predictive power across different model families reveals that while anchor influence is consistent, their positions vary, impacting whether deliberation escapes the initial opinion 'hull.'

    Hidden Anchors in Multi-Agent LLM Deliberation

    arXiv:2606.19494v1 Announce Type: new Abstract: Multi-agent LLM deliberation, where agents exchange and revise answers over several rounds, is increasingly used to improve reasoning and accuracy, yet how and why it works is rarely modelled. Such deliberation mirrors how humans re…
