| Summary | Untether AI built energy-centric AI inference accelerator chips using an at-memory compute architecture designed to minimize data movement and power consumption for neural-network workloads at the edge and in the cloud. The engineering team was acqui-hired by AMD circa mid-2025. | Cerebras Systems designs wafer-scale AI chips and supercomputers—anchored by its WSE (Wafer-Scale Engine) family—and offers cloud-based inference and training services that deliver high-throughput AI compute without the communication bottlenecks typical of multi-GPU clusters. |
