Celestial AI focuses on enhancing the performance of hyperscale data centers through its technology called Photonic Fabric™, which is an optical compute interconnect. This technology improves memory sharing efficiency, allowing data centers to reduce their Dynamic Random Access Memory (DRAM) needs by up to 35%, leading to significant cost savings. By utilizing optical interconnects, Celestial AI not only lowers power consumption but also increases bandwidth capacity, which is crucial for multi-tenant cloud environments where lower latency memory pooling can save around 23%. Additionally, the technology enables the disaggregation of High Bandwidth Memory (HBM) by using optics instead of traditional PCIe connections, addressing future demands for higher bandwidth in computing. Celestial AI aims to provide data centers with this optical connectivity to support advanced applications like Generative AI, positioning itself as a key player in the evolution of high-performance computing.
