OpenAI's speech-to-text model family. Includes the legacy whisper-1 (per-minute billing) and the newer gpt-4o-transcribe / gpt-4o-mini-transcribe / gpt-4o-transcribe-diarize (per-token billing with improved accuracy, language detection, and speaker diarization). Used via /v1/audio/transcriptions.
Current Variants
Use-when guidance is based on each model's tracked capabilities, context window, release date, and replacement status.

Frequently Asked Questions
- What is OpenAI Transcribe used for?
- OpenAI Transcribe is used for speech recognition, audio, and vision and multimodal work. The family description and listed model capabilities point to those workloads as the best fit.
- How does OpenAI Transcribe compare to GPT Realtime 2?
- OpenAI Transcribe by OpenAI is strongest where you need speech recognition, while GPT Realtime 2 by OpenAI is the closest related family to check for realtime voice. OpenAI Transcribe has 4 listed variants and reaches up to 16k context, while GPT Realtime 2 reaches up to 131k context, so compare the specs and pricing tables before choosing a production model.
- Which OpenAI Transcribe model should I use?
- If price is the main constraint, use the pricing table first because OpenAI Transcribe does not have complete provider pricing in the local data. For the most capable/latest local choice, evaluate GPT-4o Transcribe Diarize with 16k context and multimodal inputs.
