What our industry is saying.

"Network I/O is key for recommendation workloads."

Meta, OCP 2022 Global Summit

"Silicon Photonics technologies are set to significantly improve chip-to-chip and chip-to-memory interconnect. Celestial AI's Photonic Fabric has the potential to eliminate the 'Memory Wall' by connecting large amounts of shared memory at the full speed of HBM, achieving nanosecond-level latencies for AI training and inferencing. Samsung is proud to work with Celestial AI and bring our leadership in HBM, DDR, and Advanced Packaging Solutions."

Jim Elliott, Executive Vice President and Head of US Memory Business at Samsung Electronics

“The transformative potential of Celestial AI’s Photonic Fabric for AI computing, networking, and memory solutions stands to be as significant as the impact OpenAI’s GPT has had on AI models. The Photonic Fabric technology platform introduces a revolutionary suite of architectural tools for optical interconnectivity that extend from AI accelerator and GPU packages to hyperscale AI clusters. I look forward to collaborating with the team as they continue to positively disrupt the industry.”

Lip-Bu-Tan, Chairman, Walden International, Founding Managing Partner, Walden Catalyst Ventures

"The network is the only way you can actually distribute computing and build a very large computer."

Ram Velaga, GM, Core Switching Group at Broadcom

"Today's advanced Al models require exponentially more I/O bandwidth and memory capacity but are currently constrained by low bandwidth and high latency. Our Photonic Fabric™ technology is rapidly becoming the de facto standard for Accelerated Computing optical interconnectivity, driven by unparalleled performance and efficiency."

Dave Lazovsky, Co-Founder and CEO of Celestial Al

"As Al continues to rapidly evolve, it's imperative that the U.S. remains a global leader in Al innovation. The sophisticated work Celestial Al is doing on interconnectivity is critical to addressing key concerns across performance and energy efficiency to ensure the industry has the necessary infrastructure to continue to innovate and scale. We look forward to working with and supporting Celestial Al as it continues to set the industry standard."

Thomas Tull, Chairman of USIT

"The exponential growth of Al models coupled with successful validation of Celestial Al's Photonic Fabric technology in silicon has led to tremendous demand for this technology by hyperscalers. The potential of this technology to dramatically reduce the power consumption for processing extensive Al workloads enables a new era of sustainable and scalable compute capacity. We are thrilled to continue this transformative journey with Celestial Al."
