Lu et al. (2022) demonstrated that a fine-tuned frozen transformer can execute arithmetic and logic circuits without retraining, suggesting general-purpose programmability of the architecture.
Summary
A transformer model can have its weights locked down and still be taught to carry out basic computation, like addition or logic-gate operations, without being rebuilt from scratch. This matters because it shows the architecture is fundamentally a general-purpose computation engine, not just a text predictor, which grounds the assumption that transformer-based systems can be trusted to execute structured reasoning tasks.
