NVIDIA's new Rubin generation AI servers achieve 100% liquid cooling with coolant temperatures up to 45°C, hotter than a hot tub. This design significantly improves energy efficiency by reducing cooling energy consumption and water usage. In favorable climates, chiller-less operation is possible, nearly eliminating water consumption. Traditional data centers allocate up to 40% of electricity to cooling, but liquid cooling can slash costs.

A maintainer of OpenClaw built a system using local open-weight models (Gemma, Qwen) in an agent harness to triage issues and pull requests in real-time, achieving competitive performance with closed models while running on local hardware for minimal cost.
