Visionbay.ai Chooses Netris for Taiwan's Largest GPU Cluster
Visionbay.ai, a Foxconn-backed AI infrastructure unit and NVIDIA Cloud Partner, has standardized on the Netris NAAM platform (Network Automation, Abstraction, and Multi-Tenancy) to operate what it calls the largest GPU cluster and AI supercomputing center in Taiwan. Announced at GTC Taipei 2026, the selection follows a technical and procurement evaluation and cites Netris’s capabilities in multi-fabric network automation, hardware-enforced multi-tenancy, ecosystem integrations (e.g., NVIDIA DSX Air, BlueField DPUs), and regional support. Visionbay will use Netris as the network automation foundation across current and future GPU generations to accelerate deployments, provision tenants instantly, and reduce manual configuration errors.

The announcement highlights the growing demand for AI inference and the need for heterogeneous compute to maximize efficiency. Gimlet's platform routes workloads across GPUs, CPUs, and purpose-built accelerators, achieving up to 10x gains in throughput. The company counts a frontier lab and a hyperscaler as customers. The investment underscores the scaling challenges in AI infrastructure and the push for specialized solutions.
Nexthop Secures $500M to Revolutionize AI Networking
Andreessen Horowitz (a16z) announced it is a major investor in Nexthop AI’s $500 million Series B. Nexthop, led by Anshul Sadana (previously at Arista), is building purpose‑built data‑center Ethernet switches and software co‑designed for AI workloads and traffic patterns rather than traditional cloud enterprise traffic. The article argues networking switches are a core bottleneck for large distributed training and inference clusters as customers move through 400G and 800G toward 1.6 Tb/s designs and consider emerging technologies such as co‑packaged optics. Nexthop emphasizes hardware/software co‑design, open‑source support, telemetry, congestion control and load balancing, positioning itself to serve hyperscalers and fill gaps left by consolidated incumbent switch vendors.
