    Sorry you have to deal with this. You can stay on Azure OpenAI in Foundry Models. Here is what to change before April 14, 2027:

1. List your deployments. Check each gpt-4o, gpt-4o-mini and gpt-4.1 deployment: version, type and upgrade setting.
2. Pick a target with a later date. gpt-4o goes to gpt-5.1, but gpt-5.1 retires May 15, 2027. Compare newer models in the schedule.
3. Move provisioned ones yourself. Provisioned and NoAutoUpgrade deployments are not moved for you. Test, then switch traffic.
