Gas and zkML costs: compare the complete workflow
A low advertised unit price can hide proving time, retries or verification costs. Compare the same workload and acceptance criteria before choosing an implementation.
Keep the units separate
Estimated USD gas cost = gas units × effective price in gwei × 10⁻⁹ × ETH/USD. A hypothetical 21,000 gas at 10 gwei and $2,000/ETH costs $0.42. Those inputs are illustrative, not current market data. A token transfer or contract call needs its own gas estimate; L2 data and operator fees require separate inputs.

Choose your budget question
- Proof deployment: measure proving time, verification gas, model/input/key versions and handoff latency. An artifact hash is not proof verification.
- Compute purchasing: compare accepted outputs after setup, storage, egress and failures. Do not compare two GPU hourly rates without equivalent measured workloads.
- Agent fallback: compare expected cost with the worst permitted sequence; a mean does not enforce a budget.
Make the comparison reusable
Keep a baseline in the same tab, change one assumption, and rerun. Export a readable report with the measurement date and the original method. None of these tools submits a transaction, launches a GPU or benchmarks a provider for you.
Recheck when the implementation changes
A release announcement is a reason to inspect the change, not evidence that your workload is cheaper. Read the official release and measure your pinned build before replacing a budget assumption.
