How data residency works
Data Residency operates at the intersection of model execution, metering, and governance in production AI systems.
In most enterprises, data residency shows up across multiple venues. Gateways, aggregators, committed cloud capacity, and owned infrastructure, without a unified ledger. Finance sees a blended bill; platform teams see fragmented APIs.
The operational question is not whether data residency exists in your stack, but whether you can set an envelope and enforce it on the next request, not the next quarter.
- Define the concept per use case, not globally
- Measure it with evals and token accounting together
- Route to cheapest compliant supply that clears the floor
- Prove savings in shadow before enforce

Data Residency in production
Production teams encounter data residency on every live inference call. Often without explicit approval when prompts, retries, or models change.
A single change to system prompts, retrieval context, or retry policy can double monthly cost. Without a control plane in the path, that change ships in code, not through a budget envelope.
Boards and CFOs increasingly ask for unit economics per use case. Data Residency must tie to a business outcome, not token totals alone.

How o10 applies data residency
o10 sits above unified inference gateway, OpenRouter, and Amazon Bedrock: adding enforcement, evals, and KYI governance.
For data residency, o10 maintains a live ledger per use case, routes to the cheapest model clearing evals, and records model, venue, policy, and cost on every call.
