This post presents a mildly edited form of a new paper by UK AISI's alignment team (the abstract, introduction and related work section are replaced with an executive summary). Read the full paper here.

Executive summary 

AI safety via debate is a promising method for solving part of the alignment problem for ASI (artificial superintelligence).

TL;DR Debate + exploration guarantees + solution to obfuscated arguments + good human input solves outer alignment. Outer alignment + online training solves inner alignment to a sufficient extent in low-stakes contexts.

This post sets out:

• What debate can be used to achieve.
• What gaps remain.
• What research is needed to solve them. 

These gaps form the basis for [...]

Outline:

(00:37) Executive summary

(06:19) The alignment strategy

(06:53) Step 1: Specify a low-stakes deployment context

(10:34) Step 2: Train via a debate game

(12:25) Step 3: Secure exploration guarantees

(15:05) Step 4: Continue online training during deployment

(16:33) The safety case sketch

(18:49) Notation

(19:18) Preliminaries

(21:06) Key claim 1: The training process has taught the systems to play the game well

(22:19) Subclaim 1: Existence of efficient models

(23:30) Subclaim 2: Training convergence

(23:48) Subclaim 3: Convergence = equilibrium

(26:44) Key claim 2: The game incentivises correctness
