UnifabriX builds scale-up memory infrastructure for AI, breaking through the capacity and scaling constraints imposed by fixed GPU HBM. Designed for modern GPU interconnect and memory-fabric environments, our platform extends usable memory beyond the GPU package into a high-bandwidth, runtime-reconfigurable scale-up tier. Built on open and emerging interconnects including CXL, UALink, and ESUN/SUE, UnifabriX helps AI infrastructure scale more efficiently for larger models, larger working sets, and more demanding inference and training workloads.
