Zeitgeist tracks private signals to determine where the company is heading and what it means competitively.
The company's public product roadmap & what they're committed to building.
Transformer-only ASIC on TSMC 4nm with 144GB HBM3E, targeting over 10x the performance of a B200 for transformer inference.
Hosted environment for prospective customers to benchmark their workloads on Sohu before taking delivery.
Rack and multi-rack cluster software covering orchestration, RDMA networking, telemetry, and fleet reliability for customer deployments.
Also inference-only ASIC, but their LPU is a more general language-model accelerator rather than a transformer-graph-in-silicon bet.
Wafer-scale engine optimized for training and inference breadth, competing on scale rather than transformer specialization.
The incumbent Etched benchmarks against explicitly; flexible, software-mature, and the default choice Etched has to displace.
