Yoshua Bengio and collaborators from Oxford, Mila, MIT, Anthropic and more released a 182-page survey, "Understanding AI from the Inside: The State of Mechanistic Interpretability for AI Safety," led by Fazl Barez and Tung-Yu Wu, now #1 trending on alphaXiv.
Central question: does understanding how models work actually make them safer?
- Foundations: features, polysemanticity, transformer computation, and circuits
- Methods: feature extraction, circuit discovery with causal verification, explaining intermediate representations in natural language, learning dynamics, training-data attribution
- Unified framework for evaluating interpretability claims, plus six research orientations characterized by goals, assumptions, and trade-offs
- Safety applications: knowledge editing, steering, monitoring — with limitations and failure modes assessed
The team also released code notebooks reproducing key findings for hands-on experimentation.
