Weights to Code: Extracting Interpretable Algorithms from the Discrete Transformer

arXiv:2601.05770v3 Announce Type: replace Abstract: Algorithm extraction aims to synthesize executable programs directly from models trained on algorithmic tasks, enabling de novo recovery of executable mechanisms from weights without relying on human-written target programs. However, applying this paradigm to Transformer is complicated by representation entanglement (e.g., superposition), where features encoded in overlapping directions substantially hinder the recovery of symbolic expressions. We propose the Discrete Transformer, an architecture explicitly designed to bridge the gap between

Why this matters
Why now

The proliferation of complex Transformer models necessitates new methods for interpretability and verification, especially as these models are deployed in critical applications.

Why it’s important

This research addresses a core limitation of powerful black-box AI models, offering a pathway toward more transparent, auditable, and potentially human-steerable AI systems.

What changes

The ability to extract interpretable algorithms directly from Transformer weights could fundamentally alter how we develop and trust advanced AI, moving from opaque statistical models to verifiable programs.
