Distributed AI Inference

395ai nodes handle high-thread AI inference workloads across the DANI AI pipeline. CPU-native inference eliminates GPU infrastructure overhead.

⚡

Large L3 Cache Advantage

64MB of L3 cache keeps model weights hot, reducing memory latency. Critical for transformer-based inference where cache hits matter.

☼

Solar-Optimized Power

Tuned for 200W sustained draw — the sweet spot for solar generation during peak hours. No power spikes that strain the battery arms.

★

PCIe 5.0 Ready

Future-proofed for next-gen accelerators and high-speed networking. The 395ai platform scales as the AI stack evolves.
