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 higher.
- Tags unique to faster-whisper: inference, openai, quantization, transformer.
- A package for faster speech-to-text transcription based on the Whisper model, using CTranslate2.
When NOT to use faster-whisper
- * When needing to employ FFmpeg directly for audio processing as it does not require FFmpeg installation and relies instead on PyAV.
- * In environments where additional dependencies from PyAV may introduce complexity or issues.
