Despite the fact that they’re created by humans, large language models are still quite mysterious. The high-octane algorithms that power our current artificial intelligence boom have a way of doing things that aren’t outwardly explicable to the people observing them.

Progress in mechanistic interpretability could lead to major advances in making large AI models safe and bias-free. Welcome to AI Decoded, Fast Company’s weekly newsletter that breaks down the most important news in the world of AI.

Researchers at Anthropic have mapped portions of the "mind" of one of their AIs, the company reported this week, in what it called "the first ever detailed look inside a modern, production-grade large language model.
