New theory on AI interpretability proposes specialized neuron functions

An ex-OpenAI researcher has published a new essay proposing a theory on AI interpretability, suggesting that a significant majority of neurons in large language models are highly specialized, each performing a single, distinct function. This theory, if validated, could offer a breakthrough in understanding how AI models operate, potentially impacting future safety and development. The central claim about neuron specialization originates from the researcher's essay.
