TL;DR: Request attribution, team mapping, and budget policy have to work together if organisations want to cap the right users, according to Tetrate. AI gateway controls need identity and ownership data to make spend limits land on the right group instead of the wrong one.
Editorial analysis by NHI Mgmt Group, based on content published by Tetrate: “Keeping Marketers Away From Fable, or: How I Learned to Stop Worrying and Love AI Gateways”.
Key questions
Q: Why does request attribution matter for gateway-based AI controls?
A: Because the same person or workflow can generate very different spend patterns through desktop tools, coding agents, or shared keys.
Q: How do teams choose between model substitution and a hard stop?
A: Use model substitution when you want to lower request cost without interrupting service.
Q: What breaks when AI spend is not tied to team ownership?
A: Cost controls become guesswork when model usage is not tied to a named team or project.
Practitioner guidance
- Enforce gateway-only model access Make the AI gateway the only approved route for model inference so request logs, headers, and billing all land in one control point.
- Assign every key to an accountable team Map users, contractors, and service accounts to a named team or project before applying any spend policy, and review the no-team-assigned population separately.
- Use attribution before caps Read usage by team and by request source first, then decide whether alerting, hard stop, model substitution, or graceful degradation matches the business need.
Bottom line: AI gateway controls are turning model spend into a governed identity and ownership problem, not just a usage-reporting exercise.

AI gateway spend governance is becoming an identity problem, not just a procurement problem. Once model requests flow through shared gateways, the question shifts from how much was spent to who was authorised to spend it. That pushes team mapping, key ownership, and request provenance into the same control plane. Practitioners should treat model access as governed entitlement, not just metered usage.
A few things that frame the scale:
- The agentic AI market is already worth $5 billion and is projected to reach $50 billion by 2030.
A question worth separating out:
Q: What should organisations do with no-team-assigned AI spend?
A: Treat it as an ownership failure, not as harmless overflow. Unassigned spend usually means contractors, shared accounts, or service identities are consuming models without a clear budget owner. Fix the identity mapping first, then apply budget policy so enforcement lands on the right group.
