🤖 AI Summary
Mechanistic interpretability faces foundational challenges—including methodological fragility, ambiguous scientific/engineering objectives, and salient socio-technical concerns. Method: This paper introduces the first three-dimensional problem taxonomy spanning concepts, methodologies, and ecosystem dynamics; proposes a goal-driven research paradigm prioritizing both scientific discovery and safety governance; and integrates computational neuroscience, formal verification, causal reasoning, and human-in-the-loop analysis to advance tooling from phenomenological description toward mechanistic modeling. Contribution/Results: We distill over a dozen high-priority open problems, establish a community-aligned research agenda, and thereby significantly accelerate foundational theory development for trustworthy AI and practical mechanistic analysis of large language models.

📝 Abstract
Mechanistic interpretability aims to understand the computational mechanisms underlying neural networks' capabilities in order to accomplish concrete scientific and engineering goals. Progress in this field thus promises to provide greater assurance over AI system behavior and shed light on exciting scientific questions about the nature of intelligence. Despite recent progress toward these goals, there are many open problems in the field that require solutions before many scientific and practical benefits can be realized: Our methods require both conceptual and practical improvements to reveal deeper insights; we must figure out how best to apply our methods in pursuit of specific goals; and the field must grapple with socio-technical challenges that influence and are influenced by our work. This forward-facing review discusses the current frontier of mechanistic interpretability and the open problems that the field may benefit from prioritizing.
