Whisper

What is Whisper?

Whisper is a speech-to-text model developed by OpenAI. The documentation describes it as performing multilingual transcription and translation via large-scale weak supervision. It accepts audio input and outputs text in the same language or translates it into English. The model is designed to handle multiple languages and can process various audio formats. According to the repository, it is available as an open-source tool on GitHub.

Who is Whisper for?

Whisper targets developers, researchers, and organizations that need to convert spoken language into written text. The documentation indicates it supports transcription across many languages plus translation to English. This makes it useful for building voice-controlled applications, generating subtitles, analyzing meeting recordings, or processing audio archives. The open-source nature means anyone can run the model locally or integrate it into their own workflow. No special access or API key is required beyond downloading the model files.

How much does Whisper cost?

The pricing page lists Whisper as free. The model is available without any monthly subscription; the starting price is $0 per month. Users can download the model from the GitHub repository, which shows over 105,796 stars. There are no usage fees for running Whisper on your own hardware. Cloud-based inference via OpenAI’s API may incur separate charges, but the model itself remains open and free.
