## Definition

the research field that tries to understand AI models by taking apart their internal circuits, like reverse-engineering computer code.

For teachers: a subfield of machine learning research dedicated to reverse-engineering the internal parameters and computational circuits of neural networks into human-understandable algorithms.

## Examples

- Researchers use mechanistic interpretability to see exactly how a transformer solves a math puzzle.
- Safety laboratories rely on mechanistic interpretability to detect whether an autonomous system is harboring deceptive intentions.
- By treating neural weights as compiled binary programs, mechanistic interpretability seeks to uncover discrete computational circuits responsible for in-context learning.
