“Cloud-assist” means run it locally for light loads and burst to the cloud for heavier jobs. See business use cases for how each agent maps to hardware.
Frequently asked questions
Is the Supermicro 8x H100 SuperServer good for running local AI?+
It scores 100/100 on our Local AI Score (Elite tier), based on its 640GB of memory and available bandwidth/compute. That makes it suited to the Enterprise AI Business OS tier.
Which LLMs can the Supermicro 8x H100 SuperServer run?+
Comfortably: DeepSeek-R1 671B (MoE) (Q4_K_M), Llama 3.1 405B (Q8_0), Qwen3 235B-A22B (MoE) (FP16). Larger models may run with heavier quantization or by splitting across devices.
Should I run AI locally or in the cloud on the Supermicro 8x H100 SuperServer?+
Local-first is recommended. Datacenter-class capacity is best run on-prem (or in colocation) for sustained, high-volume private workloads, with cloud as overflow.
Can I turn the Supermicro 8x H100 SuperServer into a private AI Business OS?+
Yes. AI Business OS can run on this machine at the Enterprise tier, giving you private agents on your own hardware. See the call-to-action above to get started.
Turn the Supermicro 8x H100 SuperServer into a private AI Business OS
Run your own AI agents on hardware you control — private by design, no per-seat data leaving your premises. BrainOutput helps you pick the right machine and turn it into a working AI Business OS.
