Whisper tiny

Whisper tiny is a 39M-parameter speech-to-text model from OpenAI, released under the MIT license. The reviewed source lists 99+ languages (100 explicitly enumerated in our record), and the model is designed for batch transcription, with live use only through a runtime or chunking wrapper. Among the common setups we test, it ranks highest for CPU-only machines (#3 of 26 in the matcher).

Very small multilingual baseline. Good when memory and CPU load matter more than maximum accuracy.

Hardware and workload fit

These are Speech Model Match's conservative 1–5 editorial ratings, relative to the other 19 reviewed models. They come from model size, official memory guidance and documented runtimes — not from a universal benchmark. How the ratings work.

Where it is strong

  • CPU-only fit: rated 5/5
  • Apple Silicon fit: rated 5/5
  • NVIDIA GPU fit: rated 4/5
  • Speed: rated 5/5
  • Low memory use: rated 5/5
  • Edge / low-power devices: rated 5/5
  • Speech translation is supported in the model family

What to check first

  • Accuracy (relative): rated 2/5
  • No native speaker diarization — pair it with a separate diarization pipeline if you need speaker labels

How it ranks in common setups

Ranks come from the same deterministic matcher that runs on the homepage, applied to all 26 reviewed models. They are decision guidance, not accuracy claims.

How to run Whisper tiny locally

OpenAI's reference package runs Whisper on PyTorch; faster runtimes such as whisper.cpp and faster-whisper load the same weights. Runtimes below are the ones the official model card or repository documents for this model (checked November 2, 2026).

Install command shown in the official github.com page ↗:

pip install -U openai-whisper

Audio input: openai-whisper decodes files with ffmpeg and processes audio in a sliding 30-second window. The whisper.cpp command-line tool expects 16-bit WAV; its README converts with ffmpeg -i input.mp3 -ar 16000 -ac 1 -c:a pcm_s16le output.wav.

Official hardware guidance: OpenAI lists about 1 GB of VRAM for tiny (39M parameters); whisper.cpp lists about 273 MB of memory. Source ↗

Whatever runtime you choose, measure speed and accuracy on your own audio with the benchmark tool; results differ a lot between runtimes, precision and hardware.

Before you deploy Whisper tiny

A printable checklist built from the facts on this page. Tick it off before putting the model into production.

  1. Language. Confirm your language is in the 100-language list on this page, and test any accents or code-switching you expect.
  2. License. MIT: Include the copyright notice and the permission notice in all copies or substantial portions. Provided as is, without warranty. License guide.
  3. Install. Start from the official command: pip install -U openai-whisper (full run notes).
  4. Audio input. openai-whisper decodes files with ffmpeg and processes audio in a sliding 30-second window. The whisper.cpp command-line tool expects 16-bit WAV; its README converts with ffmpeg -i input.mp3 -ar 16000 -ac 1 -c:a pcm_s16le output.wav.
  5. Hardware. OpenAI lists about 1 GB of VRAM for tiny (39M parameters); whisper.cpp lists about 273 MB of memory.
  6. Features you rely on. For Whisper tiny, streaming only through a runtime or chunking wrapper; timestamps are documented; speaker labels need a separate diarization component. Test each one you need with real audio.
  7. Measure. Run 10–20 representative clips, score them with the WER calculator and record speed in the benchmark workspace before you commit.

Common questions

Can I use Whisper tiny commercially?

Permissive license; commercial use is allowed under the listed terms. The listed license is MIT; read the current license text ↗ before shipping a product, because terms can change. The license guide compares the obligations of all 26 reviewed models.

Does Whisper tiny support real-time streaming?

Not natively. Live use relies on a runtime or chunking wrapper around a batch model, which adds latency and can split words at chunk borders. If live latency is critical, compare it with a native streaming model such as Nemotron 3.5 ASR Streaming 0.6B.

Which languages does Whisper tiny transcribe?

99+ listed languages. The full list of 100 explicitly enumerated languages is shown above.

Can Whisper tiny tell speakers apart?

Not natively. Combine it with a dedicated diarization component and evaluate that component separately; the meetings guide covers this workflow.
