Clarification Request: Has the retirement date for GPT-4o been updated/extended in Azure AI Foundry?

Hello Azure AI Team,

We are tracking the model lifecycle and deprecation timelines for GPT-4o within our production environment on Azure AI Foundry.

We recently received indications that the scheduled retirement date for GPT-4o may have changed or been extended. Could a member of the product group, principal program manager, or platform architect confirm if there are any active adjustments to the deprecation roadmap?

To help narrow down the specifics, here are our setup profiles:

Model Versions Active: GPT-4o (2024-11-20) - earlier retirement date was October 1, 2026
Deployment Categories: Standard
Target Regions: East US 2
Earlier Retirement Date: October 1, 2026
New Retirement Date: 2027-04-14
Documentation Link: https://learn.microsoft.com/en-us/azure/foundry/openai/concepts/model-retirement-schedule

Thank you for your assistance!

Hi @Damaresh N ,

According to the current Microsoft Foundry model retirement schedule, GPT-4o version 2024-11-20 has a retirement date of April 14, 2027 and is currently listed as Legacy.

The October 1, 2026 retirement date currently listed in the schedule applies to GPT-4o version 2024-05-13, rather than the 2024-11-20 version. Therefore, based on the current published schedule, we would recommend verifying the deployed model version in your East US 2 deployment to confirm which retirement timeline applies.

Thank You

Based on the current Microsoft Foundry model retirement schedule, GPT-4o version 2024-11-20 is listed as Legacy with a retirement date of April 14, 2027. The published schedule currently shows that date for this specific model version. [learn.microsoft.com]

The key point is that retirement dates are tracked per model version, not just by model family name. Looking at the schedule:

GPT-4o (2024-05-13) has a different retirement timeline.
GPT-4o (2024-11-20) is listed with a retirement date of April 14, 2027. [learn.microsoft.com]

Because the retirement schedule is version-specific, an apparent date change is often the result of comparing different GPT-4o snapshots rather than a platform-wide retirement announcement.

At present, the authoritative source is the published retirement schedule itself. The documentation currently reflects April 14, 2027 for GPT-4o (2024-11-20), so that is the date that should be used for planning and migration activities unless Microsoft updates the schedule again in the future.
