Scientists have developed a new type of artificial intelligence (AI) model that can reason differently from most large language models (LLMs) like ChatGPT, resulting in much better performance in key benchmarks. The new reasoning AI, called a hierarchical reasoning model (HRM), is inspired by the hierarchical and multi-timescale processing in the human brain — the way different brain regions integrate information over varying durations (from milliseconds to minutes). […] HRM achieved near-perfect performance on challenging tasks like complex Sudoku puzzles — which conventional LLMs could not accomplish — as well as excelling at optimal path-finding in mazes.
