Pulled from the oven just right. Trustworthy, fact-dense, deeply satisfying.
Summary
This article explores fundamental concepts in mechanistic interpretability of large language models (LLMs), focusing on linear representations and superposition. It discusses how understanding the inner workings of increasingly capable LLMs is crucial for AI researchers and engineers, similar to how software engineers benefit from mental models of file systems and networking. The article aims to provide a theoretical basis for understanding the emergent intelligence in LLMs to improve our ability to harness the technology effectively.

· 4 pulledAs LLMs become larger, more capable, and more ubiquitous, the field of mechanistic interpretability -- that is, understanding the inner workings of these models -- becomes increasingly interesting and important.
Similar to how software engineers benefit from having good mental models of file systems and networking, AI researchers and engineers should strive to have some theoretical basis for understanding the 'intelligence' that emerges from LLMs.
A strong mental model would improve our ability to harness the technology.
In this post, I want to cover two fundamental and related concepts in the field of mechanistic interpretability.
