Definition
Mechanistic interpretability focuses on reverse-engineering neural networks to understand how they compute specific functions at the level of individual neurons, weights, and circuits. Instead of treating the model as a black box, researchers map out the causal pathways and logical structures within the network. This field aims to identify interpretable features and algorithms implemented by the model, providing insights into how complex behaviors emerge from simple mathematical operations, thereby enhancing safety and controllability.
