The Sequence Research #525: Anthropic's Recent Journey Into the Mind of Claude | By The Digital Insider

A major breakthrough in mechanistic interpretability.

Interpretability remains one of the toughest challenges in frontier AI models. While we are constantly dazzled by the capabilities of foundation models, we understand very little about how they work. Anthropic is one of the leading labs publishing the frontiers of AI interpretability. In some way, explainability and transparency in AI part some of the core founding ethos of the OpenAI competitor. One of the areas in which Antrophic has put a lot of focus in the

Anthropic has recently published two landmark studies that represent a pivotal advancement in the mechanistic interpretability of large language models (LLMs). The papers — Circuit Tracing: Revealing Computational Graphs in Language Models and On the Biology of a Large Language Model — introduce a novel empirical methodology inspired by neuroscience to dissect the computational substrates of Claude 3.5 Haiku. Together, they provide rigorous evidence for latent model behaviors including multistep planning, cross-linguistic generalization, and domain-specific circuit modularity. These findings challenge prevailing assumptions about the opacity of LLMs and mark a transition from output-based to internal process-based evaluation paradigms.
