The more I have thought about AI safety over the years, the more I have gotten to the point where the only worlds I can imagine myself actually feeling good about humanity’s chances are ones in which we have powerful transparency and interpretability tools that lend us insight into what our models are doing as we are training them.^[1] Fundamentally, that’s because if we don’t have the feedback loop of being able to directly observe how the internal structure of our models changes based on how we train them, we have to essentially get that structure right on the first try—and I’m very skeptical of humanity’s ability to get almost anything right on the first try, if only just because there are bound to be unknown unknowns that are very difficult to predict in advance.

Certainly, there are other things that I think are likely to be necessary for humanity to succeed as well—e.g. convincing leading actors to actually use such transparency techniques, having a clear training goal that we can use our transparency tools to enforce, etc.—but I currently feel that transparency is the least replaceable necessary condition and yet the one least likely to be solved by default.

Nevertheless, I do think that it is a tractable problem to get to the point where transparency and interpretability is reliably able to give us the sort of insight into our models that I think is necessary for humanity to be in a good spot. I think many people who encounter transparency and interpretability, however, have a hard time envisioning what it might look like to actually get from where we are right now to where we need to be. Having such a vision is important both for enabling us to better figure out how to make that vision into reality and also for helping us tell how far along we are at any point—and thus enabling us to identify at what point we’ve reached a level of transparency and interpretability that we can trust it to reliably solve different sorts of alignment problems.

The goal of this post, therefore, is to attempt to lay out such a vision by providing a “tech tree” of transparency and interpretability problems, with each successive pro...
