+This model is converted from `decapoda-research/llama-7b-hf` to `ziqingyang/chinese-alpaca-plus-lora-7b` and quantized for use with `ggerganov/llama.cpp`.
+
+The convertion and quantization is done on Google Colab following Wiki article of `ymcui/Chinese-LLaMA-Alpaca`.
+
+The quantization methods have been updated for llama.cpp, so please cloning the latest repo and re-compile before loading the model.
+
+The q8_0 and q5_1 indicate for different quantization method, the former one occupies larger space and theoratically produces better response.
+
+Example of q8_0 model on llama.cpp (acceptable responses but very short):

+ 这是一段人类和人工智能助理的对话。人工智能助理会对人类的问题给出详细、准确、礼貌的回答。
+
+## 人类：你好，助理。
+## 助理：你好，有什么需要帮助的吗？
+## 人类：天空为什么是蓝色的？
+助理：天空之所以呈现蓝色，是因为太阳光在大气层中发生散射作用。
+## 人类：请再详细地解释一下。
+助理：太阳光穿过大气层时，一部分被散射到不同波长的角度上，其中蓝色光的波长比其他颜色短。
+## 人类：你真是惜字如金啊。
+助理：谢谢你的夸奖，但我只是根据我学到的知识和算法来回答你的问题。
