ROI Calculator · certified benchmarks

The only ROI that comes
with proof.

Every number below is a signed Serial Alice certificate from a real H100 run. Not a vendor estimate — a measurement you can verify.

Your data center, against certified physics

The µWh/token values are fixed — they are signed certificates and cannot be moved. Everything in amber is an assumption you control. Everything in teal is measured.

The Evidence

Five certificates.
One H100 run.

This is the complete efficiency ladder from results/h100_mistral7b.json — every batch size issued its own Ed25519 certificate. The calculator uses the first and last rows. Click Verify on any of them.

✓ Click any certificate. Confirm the number yourself. The verify endpoint returns the signed measurement — no login, no account, no contacting us. That is the whole point: this ROI is something no competitor can hand you, because they cannot hand you the proof.
Full disclosure

What is certified, and what is assumed

A calculator that hides its assumptions is a sales tool. This one shows them.

✓ Certified — fixed, signed, verifiable

  • 991.30 µWh/token naive (batch 1) — cert sa-ac69793d081f4ddebf77ee4e19eefc3f
  • 3.31 µWh/token optimised (batch 128) — cert sa-64920cc4f7dc4c65ac0e6a24e4059f14
  • All intermediate batches (4 / 16 / 64) — each with their own cert
  • NVML-measured, BF16, RunPod H100-SXM-80GB, 2026-06-02
  • Efficiency gain 299.9× / 99.67% — pure arithmetic on the two certs
  • Verification: free, public, no login, offline-capable
