Configuration published in October allows limiting tiers used by teams. Understand how to transform speed, cost and availability into AI policy.
Direct answer
OpenAI reported on October 21, 2026 that projects can choose which service tiers they are allowed to use and that the organization can centrally restrict them. The control allows you to separate interactive loads, batch routines and critical demands without depending solely on the convention of each application. For companies, the change creates a governance point between latency requirements, budget, availability and operational authorization.
Tier becomes an architectural decision
An application should not choose premium capacity for convenience. The level needs to match the required response time and the impact of downtime.
Organization sets the ceiling; project defines use
Central policy reduces invisible exceptions, while projects can work within the authorized set according to their business case.
Fallback needs to be explicit
If a tier is blocked or unavailable, the application must know whether to wait, reduce quality, batch, or request approval, without silent change in cost.
FinOps needs to observe results
Compare cost and latency per completed flow, not just per call. A faster level can avoid abandonment; in other routines, it only increases expenses.

FAQ
Is the control valid per project?
Yes. The changelog informs tier selection in project settings and organization-level restrictions.
Is faster tier always better?
No. The choice must balance required latency, price, availability and task value.
How to implement governance?
Map flows, define authorized tiers, model fallback and track cost and time by operational result.
