Extropic is building a new type of AI chip that uses thermodynamic fluctuations—normally seen as noise—to perform efficient probabilistic computations. This allows their processors to run tasks like Monte Carlo simulations with significantly less energy, making them ideal for AI, finance, and scientific applications. Founded by quantum computing veterans, Extropic recently raised $14.1 million to bring this tech to market. Their silicon-based approach offers a lightweight alternative to traditional chips, potentially challenging giants like Nvidia in the race for AI hardware dominance.

“Last fall, we [announced X0](https://extropic.ai/writing/thermodynamic-computing-from-zero-to-one), our first silicon thermodynamic chip, and with it the world’s first desktop probabilistic computer, XTR-0. X0 demonstrated our novel probabilistic primitives in silicon: pbits, tiny circuits that turn the thermal noise of ordinary transistors into programmable randomness, using orders of magnitude less energy to generate a sample than conventional approaches. Those primitives are the building blocks of every chip we make, current and future.”
