Free Tier
The local model is available without a hosted API usage charge, but requires computing resources. No recurring free hosted whisper-1 allowance is established by these sources.

Summary

The local code and model weights use the MIT License. Local transcription requires software setup and computing resources. That local option should not be confused with a free hosted API allowance. OpenAI lists whisper-1 at $0.006 per minute, about $0.36 for an hour of audio. Its API reference identifies the hosted model as based on open-source Whisper V2. OpenAI announced deprecation on August 26, 2026, with API removal scheduled for February 26, 2027. Existing integrations need a migration plan; the notice concerns the hosted service rather than declaring downloaded weights unavailable. Recorded-file uploads have a 25 MB limit, and whisper-1 does not stream transcription responses.

Bottom line: Use local Whisper where you can manage deployment; existing hosted users should migrate before the announced February 26, 2027 API shutdown.

Whisper is OpenAI’s speech-recognition model family for turning recordings into text. The model documentation describes multilingual transcription, translation of speech into English and language identification. It is useful for preparing interview transcripts, podcast text and subtitle drafts, with human review of names, specialist terms and unclear speech before publication.

The open-source model and OpenAI’s hosted API are different ways to use the technology. The API reference identifies whisper-1 as powered by the open-source Whisper V2 model. The official repository releases the code and model weights under the MIT License. Local deployment requires a compatible software environment and computing resources; it is not the same as a free hosted transcription allowance. The hosted whisper-1 price is $0.006 per audio minute, approximately $0.36 for an hour, before any applicable taxes.

Availability matters for new integrations. OpenAI announced deprecation on August 26, 2026 and plans to remove whisper-1 from its API on February 26, 2027. This scheduled hosted-service retirement should not be confused with a statement that downloaded open-source model files disappear. Existing API users should plan migration, and new projects should compare the currently recommended transcription options.

The speech-to-text guide describes recorded-file uploads with a 25 MB limit and distinguishes transcription in the source language from translation into English. Supported output formats depend on the model, and whisper-1 does not support streamed transcription responses. Check the current API guide for file handling and replacement models before building a long-lived workflow.
