Budgeted Act-or-Defer Multi-Agent LLM Deliberation with Local Reliability Bounds

arXiv:2606.29654v1 Announce Type: new Abstract: Multi-agent deliberation among LLMs can improve reasoning, but deployment requires deciding when the current answer is reliable enough to act on and when it should be escalated to human review. We formulate this as budgeted act-or-defer decision making. At each round, the system maps the debate prefix to a low-dimensional state, computes a $k$-nearest-neighbor lower confidence bound on state-conditional correctness using calibration data, and acts only when the bound exceeds a user-specified reliability threshold. The certificate controls wrong a

Why this matters
Why now

The proliferation of advanced LLM systems necessitates robust mechanisms for managing reliability and deploying them in high-stakes environments, leading to immediate research into their practical application and control.

Why it’s important

This development addresses a critical barrier to deploying autonomous AI agents in real-world scenarios by providing a framework for trusted decision-making and human oversight.

What changes

The ability to quantify the reliability of multi-agent LLM outputs and conditionally defer to human review transforms the potential for safe and auditable AI agent deployment.

Winners
