LLM Neuroanatomy II: Modern LLM Hacking and Hints of a Universal Language

Hacker News·medium signal

A deep technical post exploring LLM internal representations received 118 points and 35 comments, investigating whether modern LLMs develop something resembling a 'universal language' in their intermediate layers. The research examines activation patterns across different model families and finds convergent internal representations despite different architectures and training data. Signals growing practitioner interest in interpretability and mechanistic understanding of LLMs.
