Frequently Asked Questions about GPT Realtime Whisper

How much does the GPT Realtime Whisper API cost per 1M tokens?+

GPT Realtime Whisper by OpenAI is priced at $0.006 per 1M input tokens and $0 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the GPT Realtime Whisper pay-as-you-go API?+

A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.

How many words and pages fit in GPT Realtime Whisper's context window?+

GPT Realtime Whisper features a 0K tokens context window, which equals approximately 336 English words or ~1 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 448 tokens.

Can I run GPT Realtime Whisper locally on my own GPU (Open Weights)?+

No, GPT Realtime Whisper is a proprietary closed-weights model hosted by OpenAI. It cannot be downloaded for local GPU execution and must be accessed via OpenAI's official API or cloud platform.

Does OpenAI train on data sent to the GPT Realtime Whisper API, and is commercial use allowed?+

API payloads are excluded from model training by default. License tier: Proprietary Commercial API (OpenAI Terms). Full commercial ownership of generated outputs. Supported deployment channels include: OpenAI Platform API, Microsoft Azure OpenAI Foundry.

How does GPT Realtime Whisper perform on coding and reasoning benchmarks?+

GPT Realtime Whisper achieves a composite Intelligence Index of 44/100, scoring 36% on SWE-bench Verified, 46% on GPQA Diamond, 66% on MMLU-Pro, and 1255 pts on Chatbot Arena Elo.

What is GPT Realtime Whisper best used for?+

GPT Realtime Whisper is best suited for: Conçu pour la synthèse vocale naturelle, la transcription audio et le dialogue parlé en temps réel, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 44/100, un contexte de 0K et un débit de 140 tok/s, GPT Realtime Whisper s’impose comme une valeur sûre de la gamme OpenAI.
