About Celestial AI

With the growth in Generative AI, data center infrastructure it is not just about the System on Chip but about the System of Chips. In the era of Accelerated Computing, data center bottlenecks are no longer limited to compute performance, but rather the system’s interconnect bandwidth, memory bandwidth, and memory capacity. Celestial AI's Photonic Fabric is the next-generation interconnect technology offering a10X increase in performance and energy efficiency over competitive technologies.

The Photonic Fabric™ is available to our customers in multiple technology offerings, including optical chiplets, optical interposers, and Optical Multi-chip Interconnect Bridges (OMIB). This enables our customers to seamlessly integrate high bandwidth, low power, low latency optical interfaces into their AI accelerators and GPUs. The technology is fully compatible with both protocol and physical layers, including standard 2.5D packaging flows. This ease of integration enables XPUs to have optical interconnects for compute-to-compute and compute-to-memory fabrics that deliver tens of Tbps bandwidth with nano-second latencies.

This innovation empowers hyperscalers to improve the efficiency and economics of AI processing by optimizing the XPUs needed for training and inference and significantly lowering the TCO2 impact. To support customer engagements, Celestial AI is cultivating a Photonic Fabric ecosystem. These tier-1 partnerships consist of custom silicon/ASIC design, system integrators, HBM memory, assembly, and packaging suppliers.

Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
