-Thanks to [tolen](https://github.com/tloen/alpaca-lora), this simple application runs Alpaca-LoRA which is instruction fine-tuned version of [LLaMA](https://ai.facebook.com/blog/large-language-model-llama-meta-ai/) from Meta AI. Alpaca-LoRA is *Low-Rank LLaMA Instruct-Tuning* which is inspired by [Stanford Alpaca project](https://github.com/tatsu-lab/stanford_alpaca). This demo application currently runs 13B version on A6000.
