AI Commentary

The hosted Whisper API offers the easiest path to OpenAI's speech recognition model without infrastructure management. Its multilingual accuracy—particularly on low-resource languages—is among the best available. The major drawback is the absence of real-time streaming, limiting it to asynchronous transcription workflows. Teams needing real-time streaming should run the open-source model on their own infrastructure or use Deepgram/Azure Speech instead.
