Choose bitsandbytes if…

  • bitsandbytes is primarily Python; FasterTransformer is C++.
  • License: bitsandbytes is MIT, FasterTransformer is Apache-2.0.
  • Tags unique to bitsandbytes: llm, machine-learning, qlora, quantization.
  • Also covers LLM Frameworks.
  • When you need advanced k-bit quantization on PyTorch for hardware like NVIDIA GPUs with SM75+ recommended.

When NOT to use bitsandbytes

  • Avoid if your setup includes Intel Gaudi processors as QLoRA 4-bit support is partial and 8-bit optimizers are not available.
  • Steer clear if you require full compatibility with ARM-based CPUs, as specific GPU optimizations might lack coverage.

Choose FasterTransformer if…

  • FasterTransformer is primarily C++; bitsandbytes is Python.
  • License: FasterTransformer is Apache-2.0, bitsandbytes 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.
