Yes, Whisper is open source; you can run it locally or use hosted APIs.

Which Whisper model size should I use?

For English, small or medium hits the accuracy/speed sweet spot on most hardware; large-v3 is worth it for other languages, heavy accents, or noisy audio. Try faster-whisper — the CTranslate2 reimplementation runs the same models several times faster with less memory, often making large practical where it was not.

Which Whisper model size should I use?

Start with "base" or "small" for speed and decent accuracy, and step up to "medium" or "large" when you need the best transcription and have the VRAM. Larger models are slower but handle accents and noise better.
