OpenAI lists snapshot IDs. A fine-tuned model follows the shutdown date of its base model.
Check your own code
The model shutdown checker finds every model ID in code or a config file that has a row, counts the days from today and shows the same quotes. Nothing you paste leaves your browser. The Breakage Calendar row for this date says what else changes that day.
This page quotes the provider’s table. It does not say that a move to the replacement was tested, and the replacement may behave differently or take different parameters. Run your own tests before you change a model ID.
