What is Extropic?

Extropic is a technology company developing hardware and computing systems designed to use the principles of thermodynamics and statistical physics for artificial intelligence. Its research explores a different approach to computation, aiming to make certain AI workloads more energy-efficient than conventional digital computing. Rather than functioning as a typical AI writing or productivity tool, Extropic focuses on the underlying infrastructure that could support future AI models, probabilistic computing, and advanced machine-learning applications.

Extropic was founded in 2022 by Guillaume Verdon and focuses on thermodynamic computing. Its technology uses Thermodynamic Sampling Units (TSUs) designed for probabilistic AI workloads. The company announced a $14.1 million seed funding round in 2023. In July 2026, it announced a nonbinding letter of intent for up to $75 million in proposed U.S. government funding. Its Z1 chip is designed to contain over 250,000 probabilistic bits while consuming under one watt. No conventional GPU replacement is yet universally established.
