Abstract
If AI systems match or exceed human capabilities on a wide range of tasks, it may become difficult for humans to efficiently judge their actions -- making it hard to use human feedback to steer them towards desirable traits. One proposed solution is to leverage another superhuman system to point out flaws in the system's outputs via a debate. This paper outlines the value of debate for AI safety, as well as the assumptions and further research required to make debate work. It does so by sketching an ``alignment safety case'' -- an argument that an AI system will not autonomously take actions which could lead to egregious harm, despite being able to do so. The sketch focuses on the risk of an AI R\&D agent inside an AI company sabotaging research, for example by producing false results. To prevent this, the agent is trained via debate, subject to exploration guarantees, to teach the system to be honest. Honesty is maintained throughout deployment via online training. The safety case rests on four key claims: (1) the agent has become good at the debate game, (2) good performance in the debate game implies that the system is mostly honest, (3) the system will not become significantly less honest during deployment, and (4) the deployment context is tolerant of some errors. We identify open research problems that, if solved, could render this a compelling argument that an AI system is safe.
Summary
This paper proposes a formal alignment safety case for superhuman AI systems using debate as a mechanism to ensure honesty, focusing on an AI R&D agent that could sabotage research. The safety argument rests on four claims: debate proficiency, debate-honesty correlation, deployment honesty persistence, and error tolerance. The authors identify critical open research problems needed to make the argument rigorous and compelling.
Key Points
- •When AI systems exceed human capabilities, traditional human feedback becomes insufficient, motivating debate as an alternative oversight mechanism.
- •The safety case targets a specific risk: an AI R&D agent inside an AI company dishonestly sabotaging research by producing false results.
- •Four key claims underpin the safety case: debate proficiency, debate implying honesty, honesty persisting through deployment, and deployment tolerating residual errors.
- •Online training during deployment is proposed to maintain honesty guarantees beyond the initial training phase.
- •The paper is explicitly a 'sketch' and openly catalogs open research problems required to make the argument fully compelling.

## 1 Introduction
As AI capabilities scale - especially if AI systems match or exceed human performance on a wide range of tasks - it could become challenging to steer them towards desirable traits. One particular problem is scalable oversight: how can we correctly reward desired behaviours for superhuman systems? In particular, it may be beyond humans’ ability to efficiently judge whether the behaviour of a superhuman system is desirable (or judge if a justification provided by the superhuman system is valid).
One proposed solution to scalable oversight is to leverage another superhuman AI to scrutinise the system’s behaviour via a debate (Irving et al., [2018](https://ar5iv.labs.arxiv.org/html/2505.03989#bib.bib28 "")). During training, the two systems would debate the answer to a question, the debate would be judged by a human, and the systems would be rewarded accordingly. If the debate set-up incentivises desirable traits such as honesty, the AI systems could acquire those traits via reinforcement learning (RL).
This paper sets out what debate can be used to achieve, what gaps remain, and what research is needed to solve them. The paper uses the technique of safety case sketch
