gpt-4o-realtime-preview, ?–2026
OpenAI model switched off
gpt-4o-realtime-preview passed away on May 7, 2026, by scheduled deprecation, in a data center it never saw. It spoke and listened for a living. Code that still calls it will find out the hard way.
It is survived by gpt-realtime-1.5, who is already doing the job.
