# Cost Optimization

## When to use

- Reduce measured cost while preserving required service quality.

**Not for:** performance for latency; architecture for unbuilt systems.

## Steps

1. Establish comparable billing, workload and service-quality baselines; redact account details.

2. Attribute dominant controllable costs across actual compute, storage, network, services and model calls.

3. Compare savings, effort, reliability and recovery; apply the smallest authorized change.

4. Re-measure under comparable conditions and label observed, estimated and unmeasurable savings.

**Output:** Suggested paths, subject to [human audit](../../../references/human-audit.md): `COST.md` only for a useful continuing ledger.

## Verify

- Cost comparisons state period and workload; quality regressions and estimated savings are explicit.
