Celestial AI focuses on high-performance computing for hyperscale data centers with its technology called Photonic Fabric™, an optical compute interconnect. This technology reduces DRAM requirements by up to 35% and lowers power consumption while increasing bandwidth capacity, which is essential for multi-tenant cloud environments. Additionally, it allows for the disaggregation of High Bandwidth Memory (HBM) using optics instead of traditional connections. The goal is to provide advanced optical connectivity that supports the growth of Generative AI and complex workloads.
