What are ExLlama and Hugging Face Transformers?

ExLlama

ExLlama is a standalone Python/C++/CUDA implementation for running quantized GPTQ Llama models with low VRAM use on modern GPUs. It is the predecessor to ExLlamaV2 and focuses on fast, memory-efficient local inference.

  • Low VRAM GPTQ inference
  • CUDA-accelerated
  • Standalone library
  • Fast token generation

Hugging Face Transformers

Transformers is a widely used library providing pretrained models for text, vision, audio, and multimodal tasks. It supports running and fine-tuning thousands of open models locally with PyTorch.

  • Thousands of pretrained models
  • Text, vision, audio support
  • Fine-tuning tools
  • Large ecosystem

ExLlama vs Hugging Face Transformers: key differences

Both projects are written in Python. Licensing differs — MIT for ExLlama versus Apache-2.0 for Hugging Face Transformers. Hugging Face Transformers is the more established project (first released 2018), while ExLlama arrived in 2023. Hugging Face Transformers has the considerably larger community, at 166,576 GitHub stars versus 2,946.
