Check the exact version
The listed identifiers are gpt-4o-2024-08-06, gpt-4o-2024-11-20, gpt-4o-mini-2024-07-18, gpt-4.1-2025-04-14, and gpt-4.1-mini-2025-04-14. Other older models have separate entries and dates on the same page.
Our take for AI geeks
Editorial analysis: treat the notice as a maintenance task. Inventory the model identifiers in scheduled jobs and integrations, then compare the recommended replacement on representative inputs before changing production settings. Our inference is that early testing buys time to find differences in output, tool behavior, or cost. We have not tested a migration for this briefing.
