An Ambitious Vision for Interpretability — AI Alignment Forum
The goal of ambitious mechanistic interpretability (AMI) is to fully understand how neural networks work. While some have pivoted towards more pragmatic approaches, I think the reports of AMI’s death have been greatly exaggerated. The field of AMI has made plenty of progress towards finding increasingly simple and rigorously-faithful circuits, including our latest work on circuit sparsity. There are also many exciting inroads on the core problem waiting to be explored. Why try to understand things, if we can get more immediate value from less ambitious approaches? In my opinion, there are two main reasons. First, mechanistic understanding can make it much easier to figure out what’s actually going on, especially when it’s hard to distinguish hypotheses using external behavior (e.g if the model is scheming). We can liken this to going from print statement debugging to using an actual debugger. Print statement debugging often requires many experiments, because each time you gain only a f
