Choose FasterTransformer if…
- FasterTransformer is primarily C++; faster-whisper is Python.
- License: FasterTransformer is Apache-2.0, faster-whisper is MIT.
- Tags unique to FasterTransformer: bert, cublas, cublaslt, cuda.
- When aiming for high performance with GPU-based FP16 computations for BERT or GPT models specifically.
When NOT to use FasterTransformer
- If looking for active development and latest improvements on LLM Inference as NVIDIA recommends TensorRT-LLM over FasterTransformer now.
- When specific frameworks not including TensorFlow, PyTorch, or Triton are required.
Choose faster-whisper if…
- faster-whisper is primarily Python; FasterTransformer is C++.
- License: faster-whisper is MIT, FasterTransformer is Apache-2.0.
- Requirements: Requires Python 3.9 or greater..
- Tags unique to faster-whisper: deep-learning, inference, openai, quantization.
- Also covers Speech & Audio.
- 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.
