Shared compatibility

  • Python · whisper-jax: Python runtime · faster-whisper: Python runtime

Choose whisper-jax if…

  • whisper-jax is primarily Jupyter Notebook; faster-whisper is Python.
  • License: whisper-jax is Apache-2.0, faster-whisper is MIT.
  • Requirements: - Python 3.9 and JAX version 0.4.5 are mandatory requirements to ensure compatibility with whisper-jax..
  • Tags unique to whisper-jax: jax.
  • - When aiming for high-performance inference, especially on Google TPU environments, whisper-jax offers significant acceleration.

When NOT to use whisper-jax

  • - If running in an environment that does not support JAX or lacks access to a Google TPU, as performance benefits may be minimal.
  • - For users without existing setup for JAX and Python 3.9, the initial onboarding might involve additional effort.

Choose faster-whisper if…

  • faster-whisper is primarily Python; whisper-jax is Jupyter Notebook.
  • License: faster-whisper is MIT, whisper-jax is Apache-2.0.
  • Requirements: Requires Python 3.9 or greater..
  • Tags unique to faster-whisper: inference, openai, quantization, transformer.
  • When you need fast speech-to-text transcription without the need to install FFmpeg separately, as Faster Whisper bundles FFmpeg libraries with PyAV.

When NOT to use faster-whisper

  • When your project strictly requires the use of FFmpeg for audio decoding, as Faster Whisper uses PyAV for this purpose.
  • When you are working in an environment where Python 3.9 or greater is not available, as this is a requirement for using Faster Whisper.
