Trust report

Choose bitsandbytes if…

  • bitsandbytes is primarily Python; candle is Rust.
  • License: bitsandbytes is MIT, candle is Apache-2.0.
  • Tags unique to bitsandbytes: llm, machine-learning, pytorch, qlora.
  • 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 candle if…

  • candle is primarily Rust; bitsandbytes is Python.
  • License: candle is Apache-2.0, bitsandbytes is MIT.
  • Tags unique to candle: ml framework, rust.
  • Also covers Developer Tools.
  • If you require a lightweight and efficient machine learning solution built in the Rust programming language for faster performance and memory safety.

When NOT to use candle

  • If your project strictly requires deep interoperability with Python-centric ecosystems or libraries such as TensorFlow or PyTorch.
  • Candle might not be the best choice if extensive pre-trained model repositories availability and ecosystem is crucial, as it may lack the breadth of models compared to more established frameworks.
