Sam Altman, CEO of OpenAI, has backed a startup called Rain Neuromorphics Inc., which designs brain-inspired chips. These chips are intended to mimic the way the brain works and serve companies using artificial intelligence (AI) algorithms2. Rain's technology is unique in that it uses analogue chips, which can decipher incremental information such as sound waves, as opposed to the digital chips that dominate the current AI market2. Rain's chip design includes a circuit called a memristor on top of silicon wafers. Memristors, originally designed by HP Labs, serve as 'artificial synapses' that allow for processing and memory to occur in the same place. This design enables AI algorithms to run faster and more energy-efficiently than existing digital AI chips2. In February 2022, Rain raised $25 million in funding, with Sam Altman being an early backer25. Altman has expressed that Rain's neuromorphic approach could significantly reduce the costs of creating powerful AI models and potentially enable true artificial general intelligence25. More recently, in December 2023, OpenAI signed a letter of intent to spend $51 million on Rain's brain-inspired chips14. This move aligns with Altman's belief that the pace of AI progress may be dependent on new chip designs and supply chains1. However, there have been some geopolitical implications related to the funding of Rain. The Saudi Aramco venture capital firm, Prosperity7, which was a lead investor in a funding round for Rain AI in 2022, was forced by the Biden administration to sell its shares in the startup. This decision was made after a review by the Committee on Foreign Investment in the United States due to potential national security implications7.
