Shared compatibility
- Python · bitsandbytes: Python runtime · LMFlow: Python runtime
Choose bitsandbytes if…
- License: bitsandbytes is MIT, LMFlow is Apache-2.0.
- Tags unique to bitsandbytes: llm, machine-learning, qlora, quantization.
- 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 LMFlow if…
- License: LMFlow is Apache-2.0, bitsandbytes is MIT.
- Tags unique to LMFlow: chatgpt, deep-learning, instruction-following, language-model.
- You require an extendable framework to fine-tune or conduct inference operations on large foundational models where a user-friendly chatbot UI can be integrated using Gradio.
When NOT to use LMFlow
- You do not need a Python-based solution for your large foundation model tasks, or if your projects specifically require languages other than Python.
- Your project requires commercial use with simplified authorization processes, since LMFlow demands signing a specific document to obtain authorization for commercial use.
