Home / Buy vs rent
Buy or rent hardware for your AI workload?
Purchase prices come from the current validated build BOM or an exact workstation configuration. Rent comes from currently priced GPU server offers. Electricity uses active hours only. Token cost per 1M output tokens is shown only when Phase 11C serving evidence is comparable on both sides.
Advanced assumptions
Your workload
SOLAR 10.7B Instruct · Q4 · 8K
- 200 active hours/month · RigForAI default assumption
- $0.15/kWh · RigForAI default assumption, not a national tariff
- 24-month comparison horizon · RigForAI default assumption
- 36-month amortization for the monthly equivalent view only · RigForAI default assumption
- Maintenance $0.00/month · RigForAI default assumption ($0)
- Idle wall power outside active hours is excluded (unknown idle draw).
- PSU rated wattage is not used as system power draw.
Buy
Cheapest validated custom build
Required catalog facts or fresh prices are missing for: gpu.
Prebuilt workstation
No currently priced compatible workstation configuration.
Rent
Memory-capable rental options with current Phase 11 prices. Hourly offers use your active hours. Monthly dedicated offers use the contract price regardless of hours. Setup fees are separate.
No currently priced memory-capable GPU server offers for this workload.
Break-even
Need a current BUY price (validated build or priced workstation) and a current RENT price to compute break-even.
Serving economics
Cost per 1M output tokens: TOKEN_ECONOMICS_UNAVAILABLE
- Phase 5 llama.cpp tok/s is not used.
- Phase 11C vLLM serving evidence is required on both BUY and RENT under the same model, runtime, precision, workload shape, serving mode, concurrency, and EXACT_HARDWARE mapping.
- runtime_not_vllm_on_both_sides
- catalog_model_mismatch_or_missing
No EXACT_HARDWARE Phase 11C mapping on the ranked rental offers for this catalog model.
Buy vs rent by AI model
Model → GPU fit → custom build, workstation, or rental server → cash-flow comparison. Calculator query states are not indexed.
