A new research paper explores the internal workings of Transformer models, revealing that their intermediate states are not random noise but rather a functional component for computing concepts. The study found that a 12-layer model processes information in two distinct phases: first, by writing into an 'off-axis' subspace, and second, by bringing the answer 'on-axis' late in the process. This off-axis computation is crucial for insulating conceptual composition from the vocabulary, and manipulating it can significantly damage the model's ability to process information, even if perplexity and other benchmarks remain unaffected.
