O modelo de voz para texto com streaming de baixa latência da OpenAI entrega deltas de transcrição ao vivo a US$ 0,017/min com latência ajustável e transcrição sensível a contexto.

É adequada para ti?

Bom para

  • Low-latency streaming transcription with tunable delay from minimal to xhigh for live captioning and voice agents
  • Context-aware transcription via prompts, keywords, and language hints configurable mid-session
  • Improved error rate over predecessor gpt-realtime-whisper for production voice applications
  • Seamless WebRTC and WebSocket integration for browser and server-side audio pipelines

Não recomendado para

  • Batch or offline file transcription where latency is irrelevant — use gpt-transcribe at 3.8x lower cost
  • Applications requiring speaker diarization, word-level timestamps, or confidence scores
  • Post-commit turn transcription with language detection — use gpt-transcribe in Realtime sessions instead

Desempenho por tarefa

Live captioning

Excellent

Purpose-built for this use case; tunable latency lets you balance speed against accuracy for on-screen captions

Meeting assistants

Very Good

Streaming deltas keep notes current during conversations, but lack of diarization limits multi-speaker meetings

Voice agent transcription

Excellent

Designed for Realtime API integration; handles turn-taking and continuous audio streams naturally

Multilingual live transcription

Very Good

Supports multiple language hints simultaneously; accuracy on code-switching depends on language pair

Domain-specific live transcription

Very Good

Keyword hints and context prompts improve accuracy, but complex domain vocabulary still benefits from custom models
