Premier models, including GPT-5.4, are disabled by default. A tenant administrator must enable them by using ADK CLI version 2.13.0.
Usage of premier models incurs additional costs (MAUs). Administrators must communicate this to users before enabling. Premier models are not available in trial tenants. When premier models are disabled, all agents (live and draft) that use them stop working immediately.
