AI cost governance: policies to control AI spend
AI cost governance is the set of policies and controls that keep AI spend predictable and attributable: budget caps and token quotas set before deployment, prompt caching to cut repeat token costs, hard limits on reasoning steps and tool calls, and unified allocation so every dollar maps to a team, feature, or customer. Governance fails when it's advisory. It works when the caps are enforced in the platform and someone owns the number.
