What's the final model name for gpt-4-1106-preview?

I’m using $model = 'gpt-4-1106-preview';
This was when I was testing last year.
What do I use in production now for gpt-4 turbo ?

gpt-4-turbo-preview now points to the latest model.

Judging from past activity, that name probably won’t be turned off for a while if they also decide to add a name without “preview”.
