The Next Frontier in Computing Infrastructure

计算基础设施的下一个前沿

As frontier AI models expand and training clusters surpass 100,000 XPUs, traditional electronic interconnects are becoming a critical bottleneck. These interconnects can’t keep pace with the growing need for high-bandwidth, low-latency data movement, which is crucial for scaling AI workloads. Lightmatter’s Passage technology addresses this challenge by leveraging 3D-stacked photonics chips to move data.

随着前沿人工智能模型的扩展和训练集群超过10万个XPU，传统的电子互连正成为一个关键瓶颈。这些互连无法满足对高带宽、低延迟数据移动的日益增长的需求，这对于扩展AI工作负载至关重要。Lightmatter的通道技术通过利用3D堆叠光电子芯片移动数据来解决这一挑战。

This breakthrough dramatically increases AI cluster bandwidth and performance, while reducing power consumption. Passage, the first photonic engine to deliver IO in 3D, frees XPU shoreline to support more memory, addressing another critical bottleneck for scaling AI performance. By transforming data movement across AI clusters, Lightmatter enables systems to scale efficiently, unlocking new levels of performance and preparing computing infrastructure for the demands of next-generation AI models..

这一突破极大地提高了AI集群的带宽和性能，同时降低了功耗。Passage是第一个提供3D IO的光子引擎，它释放了XPU海岸线以支持更多内存，解决了扩展AI性能的另一个关键瓶颈。通过改变人工智能集群之间的数据移动，Lightmatter使系统能够高效扩展，解锁新的性能水平，并为下一代人工智能模型的需求准备计算基础设施。。

“Lightmatter has the technology, leadership, and team to bring the industry the future of computing through photonics,” said Tony Wang, portfolio manager of the T. Rowe Price Science & Technology Fund. “The demand for AI supercomputers that will power the next wave of frontier AI models is strong and growing.

T.Rowe Price科技基金投资组合经理Tony Wang表示：“Lightmatter拥有通过光子学为行业带来计算未来的技术、领导力和团队。”。“为下一波前沿人工智能模型提供动力的人工智能超级计算机的需求强劲且不断增长。

We’re pleased to back Lightmatter on their mission to help power AI infrastructure.”.

我们很高兴支持Lightmatter的使命，帮助为AI基础设施供电。”。

“AI is evolving faster than anyone could have predicted, pushing the limits of data center technology,” said Erik Nordlander, General Partner at GV. “Photonics isn’t just a breakthrough; it’s the future of million-xPU data centers for AI. We’ve proudly supported Lightmatter since the beginning, and after six years, our belief in their vision has only grown stronger.

GV的普通合伙人埃里克·诺德兰德（ErikNordlander）表示：“人工智能的发展速度超出了任何人的预期，推动了数据中心技术的极限。”。“光子学不仅仅是一个突破；它是面向人工智能的数百万xPU数据中心的未来。我们从一开始就骄傲地支持Lightmatter，六年后，我们对他们的愿景的信念变得更加坚定。

Lightmatter is the definitive leader in data center photonics, and we’re excited to stand behind them as they unlock the next era of AI innovation and scale.”.

Lightmatter是数据中心光子学领域的权威领导者，我们很高兴能够支持他们开启人工智能创新和规模化的下一个时代。”。
