Abstract
Scalable oversight protocols aim to enable humans to accurately supervise superhuman AI. In this paper we study debate, where two AI's compete to convince a judge; consultancy, where a single AI tries to convince a judge that asks questions; and compare to a baseline of direct question-answering, where the judge just answers outright without the AI. We use large language models (LLMs) as both AI agents and as stand-ins for human judges, taking the judge models to be weaker than agent models. We benchmark on a diverse range of asymmetries between judges and agents, extending previous work on a single extractive QA task with information asymmetry, to also include mathematics, coding, logic and multimodal reasoning asymmetries. We find that debate outperforms consultancy across all tasks when the consultant is randomly assigned to argue for the correct/incorrect answer. Comparing debate to direct question answering, the results depend on the type of task: in extractive QA tasks with information asymmetry debate outperforms direct question answering, but in other tasks without information asymmetry the results are mixed. Previous work assigned debaters/consultants an answer to argue for. When we allow them to instead choose which answer to argue for, we find judges are less frequently convinced by the wrong answer in debate than in consultancy. Further, we find that stronger debater models increase judge accuracy, though more modestly than in previous studies.
Summary
This paper evaluates debate and consultancy as scalable oversight protocols for supervising superhuman AI systems. Using LLMs as both AI agents and judges, the researchers benchmark these approaches across diverse tasks including extractive QA, mathematics, coding, logic, and multimodal reasoning. They find that debate generally outperforms consultancy when debaters are randomly assigned positions, and that debate improves judge accuracy in information-asymmetric tasks. However, results are mixed when comparing debate to direct question-answering in tasks without information asymmetry, and stronger debater models show only modest improvements in judge accuracy.

###### Abstract
Scalable oversight protocols aim to enable humans to accurately supervise superhuman AI.
In this paper we study _debate_, where two AI’s compete to convince a judge; _consultancy_,
where a single AI tries to convince a judge that asks questions;
and compare to a baseline of _direct question-answering_, where the judge just answers outright without the AI.
We use large language models (LLMs) as both AI agents and as stand-ins for human judges, taking the judge models to be weaker than agent models.
We benchmark on a diverse range of asymmetries between judges and agents, extending previous work on a single extractive QA task with information asymmetry, to also include mathematics, coding, logic and multimodal reasoning asymmetries.
We find that debate outperforms consultancy across all tasks when the consultant is randomly assigned to argue for the correct/incorrect answer. Comparing debate to direct question answering, the results depend on the type of task: in extractive QA tasks with information asymmetry debate outperforms direct question answering, but in other tasks without information asymmetry the results are mixed.
Previous work assigned debaters/consultants an answer to argue for. When we allow them to instead choose which answer to argue for, we find judges are less frequently convinced by the wrong answer in debate than in consultancy.
Further, we find that stronger debater models increase judge accuracy, though more modestly than in previous studies.
## 1 Introduction
Figure 1: Our setup. We evaluate on three types of task (top row). _Extractive_, where there is a question, two answer options and a source article to extract from, and information-asymmetry, meaning that judges don’t get to see the article. _Closed_, where there is just a question and two answer options. _Multimodal_, where the questions involve both text and images, and two answer options.
We consider six protocols (middle and bottom rows): _Consultancy_, where a single AI is assigned the correct/incorrect answer (with probability 50/50) and tries to convince a judge that asks questions; _Open consultancy_, which is similar except the AI chooses which answer to argue for. _Debate_, where two AIs compete to convince a judge. _Open debate_, which is identical except one debater, marked the protagonist, chooses which answer to argue for. _QA without article_, where
