What changed
Time to bail on OpenAI API: older realtime and audio model families? Act. You can stay. These families shut down January 20, 2027. Move to gpt-realtime-2.1 or gpt-audio-1.5 first.
On our scale this is Act: change a setting or plan before the date. You can stay.
OpenAI removes the gpt-realtime, gpt-audio, gpt-4o-realtime and gpt-4o-audio families on January 20, 2027. Their mini versions go too. Most move to gpt-realtime-2.1 or gpt-audio-1.5.

Who is affected
Apps that call these models: Stop working on January 20, 2027.
The date to remember is January 20, 2027. Make the change before then.
What to do before January 20
- Find the old model names. Search for gpt-realtime, gpt-audio, gpt-4o-realtime, gpt-4o-audio and their mini and dated versions. Check config files and connection URLs too.
- Switch to the named replacement. Realtime goes to gpt-realtime-2.1 or gpt-realtime-2.1-mini. Audio goes to gpt-audio-1.5.
- Test voice calls before January 20. Check speech quality, delay and cost on the new model.
A few tips:
- Make the change yourself before the date. Do not wait for the last reminder email.
- Write down your current plan or settings first, so you can compare after the change.
- After the change, open your settings again and check that it worked.
