## The error OpenAI returns once gpt-4o-mini-transcribe-2025-12-15 is gone

HTTP 404

```json
{"error":{"message":"The model `gpt-4o-mini-transcribe-2025-12-15` has been deprecated, learn more here: https://platform.openai.com/docs/deprecations","type":"invalid_request_error","param":null,"code":"model_not_found"}}
```

## What to use instead

Move to gpt-live-transcribe or gpt-transcribe. Switching to gpt-live-transcribe requires more than updating an identifier, as it only runs in Realtime transcription sessions at /v1/realtime/transcription_sessions where audio is streamed in and transcript deltas return, rather than uploading files to /v1/audio/transcriptions.

gpt-live-transcribe only runs in Realtime transcription sessions (/v1/realtime/transcription_sessions): audio is streamed in and transcript deltas come back, with no file upload to /v1/audio/transcriptions.
