arXiv:2602.08857v2 Announce Type: replace Abstract: Recent work has shown that the computations of Transformers can be simulated in the RASP family of programming languages. These findings have enabled improved understanding of the expressive capacity and generalization abilities of Transformers. In particular, Transformers have been suggested to length-generalize exactly on problems that have simple RASP programs. However, it remains open whether trained models actually implement simple interpretable programs. In this paper, we present a general method to extract such programs from trained Tr
The increasing complexity and opacity of large language models necessitate methods for interpretability, and RASP provides a promising formal framework for understanding Transformer computations.
Understanding how Transformers make decisions is critical for improving their reliability, trustworthiness, and for designing more efficient and generalizable AI architectures.
This research provides a concrete method for reverse-engineering Transformer behavior into human-readable algorithms, potentially transforming how AI models are developed, debugged, and validated.

Researchers gain a clearer understanding of the internal logic and limitations of Transformer models.
Improved interpretability leads to more robust, auditable, and less 'black box' AI systems, accelerating adoption in critical domains.
The ability to 'decompile' models could lead to the automated discovery of novel algorithms and a shift away from purely data-driven model development.
