● Core

OpenAI's open-source speech-to-text model, trained on 680k hours of multilingual audio data.

Think of it like

The boring superpower; speech recognition that just works, in many languages.

Example

Transcribe a podcast or meeting recording; handles accents, background noise, and multiple languages.

How it actually works

Whisper is a sequence-to-sequence transformer trained on diverse audio (including noise). Open-source (MIT license), so widely deployed. Not perfect but strong baseline.

For product teams

Democratizes speech recognition; enables features without expensive licensing.

For engineers

Inference is slow (real-time audio > real-time output) but accuracy is good. Open weights mean fast iteration.
