Researchers have developed a new method called Unpack to analyze the internal workings of transformer models. This technique uses a backward recursion to trace how different components contribute to a model's output, identifying interaction strengths and composition labels without needing interventions or extra training. Unpack has been tested on GPT-2 and the Pythia family of models, successfully identifying specific computational paths and token-level attributions, even in complex scenarios like duplicate detection.
