At OFC 2025, Keysight Technologies introduced the Keysight Artificial Intelligence (KAI) architecture, a comprehensive end-to-end testing and emulation platform for scaling AI data centers. Designed to help infrastructure providers optimize system performance at all levels—from chip to cluster—KAI enables real-world AI workload emulation across compute, interconnect, network, and power domains. The architecture addresses a critical industry need for full-stack validation beyond isolated component testing, unlocking peak performance and reliability for AI clusters.
The KAI platform features five modular solution suites: KAI Compute, KAI Interconnect, KAI Network, KAI Power, and the newly introduced KAI Data Center Builder. Together, these suites validate everything from PCIe, CXL, and DDR interfaces to 1.6T optical interconnects and 800G Ethernet networks. KAI allows AI chipmakers, hyperscalers, and system integrators to debug, benchmark, and optimize AI data centers at every stage—from pre-silicon simulations to production-scale system operations—while emulating realistic workloads and predicting system-wide bottlenecks.
KAI Data Center Builder stands out as a novel system-level emulator, capable of mimicking the behavior of full-scale AI clusters under realistic workloads. It enables operators to forecast performance degradation, identify vulnerabilities across components, and fine-tune their deployments for maximum ROI. By integrating power, network, and traffic behavior into one unified view, Keysight empowers organizations to validate not just component compliance but interoperability, performance, and energy efficiency across their AI infrastructure.
This launch comes amid surging demand for AI model training and inference, where data center bandwidth, latency, and thermal constraints increasingly determine scalability. With KAI, Keysight brings decades of test and measurement expertise to bear on one of the fastest-moving innovation cycles in the industry, supporting hyperscalers in deploying next-generation AI/ML ASICs and network fabrics.
