GPT-4o Transcribe

GPT-4o Transcribe is a speech-to-text model built on the GPT-4o architecture, delivering lower word error rates and stronger language recognition than the original Whisper models for production transcription workloads.

import { readFile } from 'node:fs/promises';


const result = await transcribe({
  model: gateway.transcriptionModel('openai/gpt-4o-transcribe'),
  audio: await readFile('audio.mp3'),

Frequently Asked Questions

  • How do I access GPT-4o Transcribe through AI Gateway?

    Use the AI SDK's transcribe function from the ai package with this model's slug. Audio support on AI Gateway is in beta. Authenticate with an AI Gateway API key or OIDC token; no OpenAI credentials are needed in your application.

  • How does GPT-4o Transcribe compare to Whisper?

    GPT-4o Transcribe improves word error rate over the original Whisper models and outperforms Whisper v2 and Whisper v3 on the FLEURS multilingual benchmark. The gains are largest on accents, noisy environments, and varying speech speeds.

  • When should I use gpt-4o-mini-transcribe instead?

    Use the mini variant when volume and cost dominate and your audio is relatively clean. Reserve GPT-4o Transcribe for recordings where accuracy failures are expensive: noisy calls, strong accents, or compliance-grade transcripts.

  • Can I stream transcription results through AI Gateway?

    AI Gateway transcription is batch today. Send a complete file buffer, base64 string, or URL with the transcribe function and receive the transcript in the response.

  • How is GPT-4o Transcribe priced?

    Pricing is listed on this page. Rates reflect the providers routing through AI Gateway and update when providers change list prices.

  • Does GPT-4o Transcribe support zero data retention through AI Gateway?

    Zero Data Retention is not currently available for this model. Zero Data Retention is offered on a per-provider basis. See https://vercel.com/docs/ai-gateway/capabilities/zdr for details.
