How do you start calling GPT-4o Transcribe?

Use the model ID gpt-4o-transcribe through the compatible transcription endpoint. It converts audio to text with improved accuracy.

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

gpt-4o-transcribe 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.

How much does GPT-4o Transcribe cost?

Check the current pricing page for per-minute or per-token transcription costs.

How does gpt-4o-transcribe compare with other models, and what should you compare?

Compare gpt-4o-transcribe against models of similar capability and pricing on your actual workload. Evaluate latency, output quality, instruction following, and cost per task. Run side-by-side tests with your own prompts — the best model depends on your specific use case, not just benchmark scores.

What audio formats does GPT-4o Transcribe support?

Confirm the current supported audio formats in the model documentation. Test with your specific audio files.

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

Yes. GPT-4o Transcribe 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 . Keep your current request and response handling.

Does GPT-4o Transcribe support streaming output?

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