Summary

Safe deployment of an AI system requires that we can make confident claims about its behaviour on out-of-distribution deployment inputs on the basis of only pre-deployment evaluations. One approach to making such claims is to take a cognitive perspective, in which we interpret the AIs behaviour in terms of latent cognitive constructs, such as motivations, intentions, and goals. Because the same behaviour may be compatible with a range of underlying cognition—such as scheming, fitness-seeking, or aligned motivations—inferring cognition from a behavioural snapshot can be tricky. In this post, we introduce the idea of Developmental Cognitive Interpretability (DCI), which aims to model how cognitive constructs change over the course of training. Further, by understanding how cognition results from training pipelines, we can predict agent behaviour resulting from pipelines that have not yet been tested.

We discuss core assumptions and philosophical background of DCI, and lay out a broader research agenda. We have some initial evidence that the methodology works in at least one toy setting, and our current main uncertainty is whether we can scale our approach to LLMs. We invite those interested in working on these problems to reach out to us at jrb239[at]cam[dot]ac[dot]uk and edward[at]geodesicresearch[dot]org.
