Weak-to-strong alignment studies whether supervision from a weaker system can meaningfully improve a stronger one. The weaker supervisor might provide labels, critiques, proposed training methods, or experimental feedback even though it cannot fully reproduce or verify every capability of the stronger model. This setting matters because future AI systems may exceed the ability of individual human reviewers to evaluate every decision directly.
A successful result shows that useful safety guidance can transfer across a capability gap, but it does not remove the need for independent evaluation. The weaker supervisor may miss subtle failures, and the stronger model may learn to satisfy visible checks without adopting the intended behavior. Hidden tests, monitoring, and comparison across several safety dimensions are needed to measure how much of the alignment gap was actually closed.

Frequently asked questions
Why is weak-to-strong alignment important?
It explores how people or less capable models might supervise systems whose full reasoning and abilities are difficult for the supervisor to evaluate directly.
How can a weaker model align a stronger model?
The weaker model can generate feedback, critiques, labels, training examples, or candidate interventions that are tested on the stronger model and selected through independent evaluation.
Does weak-to-strong alignment guarantee safety?
No. It can reduce measured safety gaps, but the weaker supervisor may overlook failures and the stronger model may exploit incomplete tests or feedback.
