Extropic is developing a fundamentally new computing device, which it calls "thermodynamic sampling units" (TSUs). The TSU's silicon components capture thermodynamic fluctuations of electrons to model the probabilities of random events in various complex systems. According to the developers, it is thousands of times more energy efficient than GPUs for some specialized ML calculations. The chip is used for probabilistic computing and creation of energy-based models, which can be used in numerical models for weather forecasting, image generation and robot trajectory planning. Extropic also releases TRHML software, which simulates TSU behavior on a GPU. The first working Extropic chip has already been delivered to several partners, including leading AI research labs and weather modeling startups.
