How does this compute model calculate hardware TCO and inference cost?

It models compute hardware amortization, colocation rack power, PUE cooling efficiency, network egress, and token throughput per second across modern LLM and AI workloads.

How does on-premise hardware compare to hourly cloud rentals?

Dedicated compute clusters generally reach cost parity and breakeven against hyperscaler on-demand instances within 10 to 14 months at sustained 65%+ utilization.

Can I customize the power consumption and electricity rate?

Yes, power draw per node (kW), facility PUE, and local utility electricity rates ($/kWh) can be customized directly in the input fields.
