  # gpt-fast
  Simple and efficient pytorch-native transformer text generation.
  
  Featuring:
  1. Very low latency
  2. <1000 lines of python
  3. No dependencies other than PyTorch and sentencepiece
  4. int8/int4 quantization
  5. Speculative decoding
  6. Tensor parallelism
  7. Supports Nvidia and AMD GPUs
  
  This is *NOT* intended to be a "framework" or "library" - it is intended to show off what kind of performance you can get with native PyTorch :) Please copy-paste and fork as you desire.

  # gpt-fast
  Simple and efficient pytorch-native transformer text generation. This repository is a reference implementation, *not* a framework or library, designed to showcase state-of-the-art LLM inference performance with native PyTorch in under 1000 lines of Python. It's ideal for copy-pasting and forking to build highly optimized text generation directly into your projects.

  ## FAQ
  
  **Q: Is gpt-fast intended for production use as a standalone serving solution?**
  A: gpt-fast is primarily a research-oriented, highly optimized reference implementation designed to showcase state-of-the-art LLM inference performance with native PyTorch. While it demonstrates excellent performance, it is not a fully-fledged, production-hardened serving framework. Users adopting it for production should evaluate its suitability, maturity, and integration needs carefully, as it's intended for copy-pasting and adapting rather than direct deployment as a library.
