What it costs to run MiniCPM4.1 8B — $0 markup

• On your own machine — $0. Runs free locally if you have about 7 GB of VRAM at Q4_K_M (point Spanvero at LM Studio, Ollama, or llama.cpp).
• On your own rented GPU — from $0.26/hr. NVIDIA RTX 3090 24GB at the direct Vast.ai price (≈ $0.10 a session), $0 markup.
• Via your own API key — $0.17/1M tokens (blended input + output). No GPU to manage (rough estimate for this size).

When does owning hardware beat the API?

At $0.17/1M tokens, the cheapest API for MiniCPM4.1 8B stays cheaper than a used RTX 3090 at any daily volume — electricity alone costs more per token than the API does.

Local is never $0 — every figure here includes electricity and hardware amortization. Speeds come from published 7-8B Q4 benchmarks (your model, quant, and context will differ); break-even volumes are rounded to 2 significant figures.
