Overview
Celestial AI, has secured $100 million in Series B funding led by IAG Capital Partners, Koch Disruptive Technologies (KDT), and Temasek’s Xora Innovation fund. Additional investors include Samsung Catalyst, Smart Global Holdings (SGH), Porsche Automobil Holding SE, The Engine Fund, imec.xpand, M Ventures and Tyche Partners. Celestial AI is renowned for its Photonic Fabric technology platform that delivers optical connectivity performance levels a decade more advanced than existing technologies.
As advanced AI models, such as Large Language Models (LLM), demand ever-increasing memory capacity and bandwidth, electrical connectivity is becoming a limiting factor in data transmission. This development pushes optical interconnectivity to the forefront as the critical component for accelerated computing. The inability of cloud service providers (CSPs) and hyperscale data centers to separate memory scaling from computing - the "memory-wall" challenge - highlights the significance of Optical Compute Interconnect (OCI) as the only viable solution to allow for disaggregated, scalable data center memory and accelerated computing.
In response to these challenges, Celestial AI is launching the Photonic Fabric, an optical interconnect for disaggregated, exascale compute, and memory clusters. This technology can deliver data to any location on the compute die, directly to the point of consumption, with 25x greater bandwidth and over 10X lower latency and power consumption than any optical interconnect alternative, such as Co-Packaged Optics (CPO).
Celestial AI is currently establishing a robust Photonic Fabric ecosystem in collaboration with AI compute, memory suppliers, hyperscalers, and high-volume commercial supply chain partners. The company's Photonic Fabric technology and silicon-proven IP are available through a technology licensing program, offering customers the flexibility to integrate the technology into their existing platforms or harness the full end-to-end benefits with Celestial AI’s Orion™ AI accelerator.
