Language models learn to read neural network weights for safety audits

Researchers have developed a novel interpretability method called "Weight Oracles" that allows language models to diagnose properties of neural networks by directly analyzing their raw weights. This approach bypasses the need for traditional behavioral testing with specific inputs. In initial phases, an explainer LLM successfully simulated small transformer forward passes from weights alone, achieving high accuracy. The method was then applied to safety auditing, where an oracle trained on benign anomalies demonstrated strong zero-shot performance in detecting backdoors, outperforming hand-crafted statistical detectors.
