How do you start calling GPT-4o Transcribe Diarize?

Use the model ID gpt-4o-transcribe-diarize through the compatible transcription endpoint. It adds speaker labels to transcriptions.

How does diarization work in GPT-4o Transcribe Diarize?

The model automatically identifies and labels different speakers in audio, associating each segment with the correct speaker. Test with your multi-speaker audio to verify accuracy.

Can you call GPT-4o Transcribe Diarize with the OpenAI SDK you already use?

Yes. GPT-4o Transcribe Diarize is reachable through an OpenAI-compatible endpoint, so an existing OpenAI SDK client works after pointing the base URL at MixRoute and setting the model parameter to gpt-4o-transcribe-diarize . Keep your current request and response handling.

When was GPT-4o Transcribe Diarize released, and is it still maintained?

GPT-4o Transcribe Diarize is listed with catalog status stable. Check the model page for deprecation notices before you build a long-lived integration on it.

How much does prompt caching save on gpt-4o-transcribe-diarize?

gpt-4o-transcribe-diarize supports prompt caching, which can significantly reduce costs for repeated prompts with shared prefixes. The cache read price is substantially lower than the standard input price. Check the current pricing page for the exact cache hit discount ratio for gpt-4o-transcribe-diarize.

How do you get a cache hit on gpt-4o-transcribe-diarize?

The current GPT-4o Transcribe Diarize listing publishes no cache-read rate, so cached-prefix billing is not part of its pricing. Treat repeated prefixes as fresh input when you size the workload, and confirm with the provider before designing for a cache saving.

Does GPT-4o Transcribe Diarize support streaming output?

Yes. GPT-4o Transcribe Diarize is declared as supporting streamed responses.
