Phase Change

As Transformer generative models continue to scale and gain increasing real world use , addressing their associated safety problems becomes increasingly important. Mechanistic interpretability – attempting to reverse engineer the detailed computations performed by the model – offers one possible avenue for addressing these safety issues. If we can understand the internal structures that cause Transformer models to produce the outputs they do, then we may be able to address current safety problems more systematically, as well as anticipating safety problems in future more powerful models. Note that mechanistic interpretability is a subset of the broader field of interpretability, which encompasses many different methods for explaining the outputs of a neural network. Mechanistic interpretability is distinguished by a specific focus on trying to systematically characterize the internal circuitry of a neural net.
