Nick Cammarata from Goodfire argues that neural networks are inherently legible, challenging the prevailing view of polysemanticity and superposition. The research posits that what appeared as arbitrary concept packing is actually 'recursive generalization,' suggesting that mechanistic interpretability can proceed by studying network mechanisms directly rather than first untangling them.

Goodfire Argues Neural Networks Are Already Clean: Recursive Generalization Replaces Polysemanticity in Interpretability
- Challenges conventional wisdom: Posits that polysemanticity and superposition are manifestations of recursive generalization, not noise hindering interpretation.
- Simplifies research path: Advocates for direct study of neurons and circuits without prior complex feature decoupling or reconstruction.
- Boosts interpretability outlook: If the 'clean' hypothesis holds, mechanistic interpretability becomes more feasible, accelerating understanding of model behavior.
