Inside the 'Biological' Brain of Large Language Models
Insights from the Yannic Kilcher episode “On the Biology of a Large Language Model (Part 1)”, published April 5, 2025.
In "On the Biology of a Large Language Model (Part 1)" (Yannic Kilcher, April 2025), anthropic’s latest research uses 'transcoder' models to map the internal circuitry of LLMs, revealing how they process information. The findings suggest that models perform abstract reasoning in their middle layers, often relying on English as a default 'thinking' language while using multilingual features to bridge concepts across different tongues.
