arXiv:2606.16920v1 Announce Type: cross Abstract: Circuit discovery is a key technique in mechanistic interpretability to pinpoint the model components that are crucial for performing a given task. Although the current state-of-the-art method (EAP-IG) performs well on the metric of (un)faithfulness, it suffers from substantial variability. This includes resampling variance, where the circuit changes when we probe with a new batch of data from the same distribution; rephrasing variance, where the discovered circuit shifts when the prompts are rephrased; and sample-wise variance, where a circuit
The increasing complexity and opacity of large language models necessitate advanced interpretability techniques to understand their functions and underlying mechanisms.
Understanding the variability and reliability of circuit discovery methods is crucial for building trustworthy and controllable AI systems, especially as LLMs become more integrated into critical applications.
This research highlights limitations in current interpretability methods, suggesting a need for more robust and consistent techniques to truly demystify AI model behavior.
