About
Based in Silicon Valley (San Francisco, California, United States)
We're building state-of-the-art, energy-efficient reconfigurable dataflow chips ("XPUs") for AI training and inference.
Given their polymorphic (reconfigurable) nature, our XPU chips can be optimized for each AI model, optimizing dataflow and reducing memory movement through localization, instruction fusion, and layer fusion, delivering superior energy efficiency, versatility, and throughput compared to traditional accelerators like GPUs and TPUs.
We're essentially building the substrate that will power all future knowledge and scientific discovery.
