OpenAI signed $51M deal to buy ‘brain’ chips from Sam Altman portfolio firm
A story that got left out of the corporate infighting that led to Sam Altman’s firing, then re-hiring as CEO of OpenAI, was about the firm’s relationship with a startup called Rain Neuromorphics, which is developing a neuromorphic processing unit (NPU) designed to replicate features of the human brain.
Rain says their brain-inspired NPUs could potentially offer 100 times more computing power and, for AI training purposes, deliver up to 10,000 times greater energy efficiency than the GPUs predominantly used by AI developers.
In theory, these NPUs could provide a big boost in processing power for portable “edge” devices such as smartphones or vehicle infotainment devices located far from a data center. Samsung, for instance, says that the Galaxy S24 – its next-generation flagship phone – will be AI-enhanced, but smartphones are limited in their processing abilities by their portable nature.
