Points to gpt-4o-2024-08-06. The models API lists no shutdown date for this alias; gpt-4o-2024-08-06 shuts down on 14 January 2027.
Fine-tuned versions of this model follow the same shutdown date.
Microsoft's lifecycle policy uses this version as its example: Standard deployments move to gpt-5.6-sol on 9 December 2026.
Deprecated on Azure: only subscriptions that have already deployed this version can create new deployments.
Standard, Global Standard and Data Zone Standard deployments are upgraded to the replacement at retirement unless versionUpgradeOption is NoAutoUpgrade. Provisioned deployments are not upgraded and must be moved by hand.
