Large Language Models (LLM), represented by ChatGPT and GPT-4, have sparked a new wave of research in the field of natural language processing, demonstrating capabilities of Artificial General Intelligence (AGI) and attracting widespread attention from the industry. However, the expensive training and deployment of large language models have posed certain obstacles to building transparent and open academic research.

To promote open research of large models in the Chinese NLP community, this project has open-sourced the Chinese LLaMA model and the Alpaca large model with instruction fine-tuning. These models expand the Chinese vocabulary based on the original LLaMA and use Chinese data for secondary pre-training, further enhancing Chinese basic semantic understanding. Additionally, the project uses Chinese instruction data for fine-tuning on the basis of the Chinese LLaMA, significantly improving the model's understanding and execution of instructions.

Disclaimer: Resources related to this project are for academic research purposes only.

Main contents of this project:

  • 🚀 Open-sourced the Chinese LLaMA large model pre-trained on Chinese text data

Model Download

⚠️ User Notice (Must Read)

The official LLaMA model released by Facebook prohibits commercial use, and the official model weights have not been open-sourced (although there are many third-party download links available online). In order to comply with the relevant licenses, it is currently not possible to release the complete model weights. We appreciate your understanding. After Facebook fully opens up the model weights, this project will update its policies accordingly. What is released here are the LoRA weights, which can be seen as a "patch" for the original LLaMA model, and the complete weights can be obtained by merging the two.

Download Links

Note: The following models cannot be used directly and must be reconstructed following the steps provided in this project's Model Reconstruction section.

[1] The original LLaMA model needs to be applied for use in Facebook-LLaMA or refer to this PR. Due to copyright issues, this project cannot provide downloads, and we ask for your understanding.

[2] The reconstructed model is slightly larger than the original LLaMA (due to the expanded vocabulary); the 7B model is about 13G+.

[3] After downloading, be sure to check whether the SHA256 of the ZIP file is consistent; for the full value, please see SHA256.md.

The file directory inside the ZIP file is as follows (using Chinese-LLaMA as an example):

chinese_llama_lora_7b/
  - adapter_config.json       # LoRA weight configuration file
  - adapter_model.bin         # LoRA weight file
  - special_tokens_map.json   # special_tokens_map file
  - tokenizer_config.json     # tokenizer configuration file
  - tokenizer.model           # tokenizer file

Model Reconstrcution

Preparation

  1. Make sure the machine has enough memory to load the complete model (e.g., 13-15G for the 7B model) for the model merging operation.

  2. Before merging, make sure that the SHA256 of the base model and the LoRA model patch are consistent with those in SHA256.md, otherwise, the merge operation cannot be performed.

    • The original LLaMA contains the following files: tokenizer.model, tokenizer_checklist.chk, consolidated.00.pth, params.json

    • The SHA256 of the weight file consolidated.00.pth: 700df0d3013b703a806d2ae7f1bfb8e59814e3d06ae78be0c66368a50059f33d

  3. Dependencies:

    • ⚠️ You MUST use the latest 🤗Transformers library. The current release v4.27 does not support LLaMA.
    • install sentencepiece and peft using pip command
pip install git+https:/huggingface/transformers
pip install sentencepiece
pip install peft

Step 1: Convert the original LLaMA model to HF format

Use the script convert_llama_weights_to_hf.py provided by the latest 🤗transformers to convert the original LLaMA model to HuggingFace format. This project is not responsible for the compliance and correctness of using third-party (non-Facebook official) weights, such as the decapoda-research/llama-7b-hf in the HuggingFace model library (use at your own risk).

⚠️ Please put the original LLaMA's tokenizer.model file in--input_dir, and the other files in ${input_dir}/${model_size}.

python src/transformers/models/llama/convert_llama_weights_to_hf.py \
    --input_dir path_to_original_llama_root_dir \
    --model_size 7B \
    --output_dir path_to_original_llama_hf_dir

Step 2: Merge LoRA weights to generate consolidated model weights

Use the script merge_llama_with_chinese_lora.py to expand the Chinese vocabulary of the original LLaMA model (in HF format), and merge it with LoRA weights to generate consolidated model weights consolidated.*.pth (it is recommended to check the SHA256 values) and the configuration file params.json. Please execute the following command:

python scripts/merge_llama_with_chinese_lora.py \
    --base_model path_to_original_llama_hf_dir \
    --lora_model path_to_chinese_llama_or_alpaca_lora \
    --output_dir path_to_output_dir

where:

  • --base_model: directory where the HF format LLaMA model weights and configuration files are saved (generated in Step 1)
  • --lora_model: directory where the Chinese LLaMA/Alpaca LoRA model compressed file downloaded in the previous section is located, or the model name on Hugging Face Model Hub: ziqingyang/chinese-alpaca-lora-7b or ziqingyang/chinese-llama-lora-7b
  • --output_model: directory to save the consolidated model weights (default: ./)

(Optional) If necessary, you can convert the .pth files generated in this step to HuggingFace format using the script in Step 1.

Quick Deployment

The research community has developed many excellent model quantization and deployment tools to help users easily deploy large models locally on their own computers. In the following, we'll take the llama.cpp tool as an example and introduce the detailed steps to quantize and deploy the model on MacOS and Linux systems. For Windows, you may need to install build tools like cmake, and you can refer to the steps in alpaca.cpp. For a local quick deployment experience, it is recommended to use the instruction-finetuned Alpaca model.

Before running, please ensure:

  1. The model quantization process requires loading the entire unquantized model into memory, so make sure there is enough available memory (7B version requires more than 13G).
  2. When loading the quantized model (e.g., the 7B version), ensure that the available memory on the machine is greater than 4-6G (affected by context length).
  3. The system should have make (built-in for MacOS/Linux) or cmake (need to be installed separately for Windows) build tools.
  4. It is recommended to use Python 3.9 or 3.10 to build and run the llama.cpp tool (since sentencepiece does not yet support 3.11).

Step 1: Clone and build llama.cpp

Run the following commands to build the llama.cpp project, generating ./main and ./quantize binary files.

git clone https:/ggerganov/llama.cpp
cd llama.cpp
make

⚠️ Important Reminder (2023/3/30): The community around the llama.cpp tool is very active, and has recently updated the related algorithm strategies to achieve a 10-100x faster loading speed (it is indeed faster in practice). Please note that the new version of the code cannot load old models, and you need to regenerate ggml format files. You can:

  • If you still have the merged model's .pth file, you can use the latest llama.cpp code to re-quantize it.
  • If you have deleted the previous .pth file, you can use the migrate-ggml-2023-03-30-pr613.py provided by llama.cpp to convert the old model to the new model.

Step 2: Generate a quantized model

Depending on the type of model you want to convert (LLaMA or Alpaca), place the tokenizer.* files from the downloaded LoRA model package into the zh-models directory, and place the params.json and the consolidate.*.pth model file obtained in the last step of Model Reconstruction into the zh-models/7B directory. Note that the .pth model file and tokenizer.model are corresponding, and the tokenizer.model for LLaMA and Alpaca should not be mixed. The directory structure should be similar to:

llama.cpp/zh-models/
   - 7B/
     - consolidated.00.pth
     - params.json
   - tokenizer.model

Convert the above .pth model weights to ggml's FP16 format, and generate a file with the path zh-models/7B/ggml-model-f16.bin.

python convert-pth-to-ggml.py zh-models/7B/ 1

Further quantize the FP16 model to Q4, and generate a quantized model file with the path zh-models/7B/ggml-model-q4_0.bin.

./quantize ./zh-models/7B/ggml-model-f16.bin ./zh-models/7B/ggml-model-q4_0.bin 2

Step 3: Load and start the model

Run the ./main binary file, with the -m command specifying the Q4 quantized model (or loading the ggml-FP16 model). Below is an example of decoding parameters:

./main -m zh-models/7B/ggml-model-q4_0.bin --color -f ./prompts/alpaca.txt -ins -c 2048 --temp 0.2 -n 256 --repeat_penalty 1.3

Please enter your prompt after the >, use \ as the end of the line for multi-line inputs. To view help and parameter instructions, please execute the ./main -h command. Here's a brief introduction to several important parameters:

-c controls the length of context, larger values allow for longer dialogue history to be referenced
-ins activates the conversation mode for the ChatGPT class
-n controls the maximum length of generated responses
--repeat_penalty controls the penalty for repeated text in the generated response
--temp is the temperature coefficient, lower values result in less randomness in the response, and vice versa
--top_p, top_k control the sampling parameters

System Performance

To quickly evaluate the actual performance of the related models, this project has compared the performance of the original Alpaca-7B and the Chinese Alpaca-7B of this project on some common tasks, given the same prompt. The evaluation is not absolutely rigorous, and the results are for reference only. Feel free to try it out yourself. For more tests, please refer to EXAMPLES.md.

Note: The tested models are both 4-bit quantized models (the theoretical performance is somewhat worse than the non-quantized versions). The responses have randomness due to the influence of decoding hyperparameters.

为什么天空是蓝色的? The sky appears blue because of Rayleigh scattering, which occurs when light from distant objects passes through air molecules and is scattered back in all directions by the same number of times. This results in more red (longer wavelength) than violet (shorter wave length). 因为太阳在白天时发出光,这些光线被散射后以色红外线波长的光谱。当它们经过大气层和空气中折射、反射等过程之后,最终到达我们的眼睛,我们看到的就是蓝色的天空。
如何做披萨? The process for making a prayer flag is as follows: 1) Cut out the pattern of your choice from fabric. 2) Sew or glue down one side, leaving about an inch open on each end to insert poles later (or you can use string). 3) Fold over and sew/glue along both sides again so that it is doubled up with the pattern showing through.
4) Insert two wooden dowels or metal rods into either side of your flag, leaving about an inch open on each end to insert poles later (or you can use string). 5) Tie a knot at both ends and hang them outdoors for sunlight exposure overnight.
6) In the morning take down flags from their hanging places outside so that they are exposed directly to light, then let dry in full daytime sunshine until completely dried (about 2-3 days).
制作披萨的步骤:
1.准备面团和酱料。
2.将面团放在烤盘上,用勺子在上面挖出一些小洞口(可以根据个人喜好选择大小)。
3.涂上调味的番茄酱或其他配菜于表面。
4.放进预热好的烤箱中以适当温度烘烤15-20分钟直到披萨金黄色且酥脆可口为止,取出后切块享用即可。

你是一个作文生成器,请以《绿水青山就是金山银山》为题写一篇议论文。 Green Mountains is a metaphor for Gold Mountain. Green mountains represent the hope and dreams of people, while gold mountain represents material wealth that can be attained through hard work. The two are not mutually exclusive; one may have both green mountains (hope) as well as golden hills (wealth). However, if we focus solely on pursuing money without regard for our hopes and desires then the result will likely lead to disappointment or even failure in achieving either of them.

The metaphorical comparison between Green Mountains and Gold Mountain is a powerful one that can be used as an analogy when discussing life goals, ambitions, dreams etc., because it reminds us not only what we want but also how to get there - through hard work with the right attitude in mind.
《绿水青山就是金山银山》是一句古成语,意思是“自然风光和财富一样珍贵。”这句话的寓意是,自然资源和环境的重要性,它们不仅可以给人们带来快乐和幸福,而且也对社会经济的发展具有重要意义。在当今世界中,我们经常看到一些人为了追求金钱而忽视了环境保护问题。然而,环境问题已经成为了一个全球性的话题,越来越多的人开始关注环保问题,并采取行动来保护自然资源。在我看到的,一个重要的原因是,人们已经认识到了自然资源和环境的重要性。例如,许多人现在更加注重节约能源、减少污染等环保措施。这表明,人们对于环境保护问题的认识正在不断提高。因此,我认为,我们应该珍惜自然资源和环境,以保护它们为我们所处的美丽世界。只有这样,我们才能够享受到绿水青山就是金山银山的价值,并让它成为我们的财富。

Training Details

The entire training process includes three parts: vocabulary expansion, pre-training, and instruction fine-tuning. The training code refers to the run_clm.py in 🤗transformers and the relevant parts of dataset processing in the Stanford Alpaca project.

Preparation: Vocabulary Expansion

Due to the limited support for Chinese (and other non-English languages) in the original LLaMA,

  • We further expanded the Chinese vocabulary based on training with the general Chinese corpus using sentencepiece to create a 20K Chinese vocabulary, which was then merged with the original LLaMA model's 32K vocabulary.
  • After removing duplicate tokens, the final Chinese LLaMA vocabulary size is 49,953.
  • It should be noted that during the fine-tuning stage, Alpaca has one more pad token than LLaMA, so the Chinese Alpaca vocabulary size is 49,954.

For more information on the motivation behind expanding the Chinese vocabulary, please refer to the FAQ.

Pre-training

In the pre-training phase, the general Chinese corpora (consistent with the corpora used in Chinese BERT-wwm, MacBERT, LERT, PERT) were used for further pre-training based on the original LLaMA weights. This process is divided into two stages:

  1. Stage One: Fix the parameters of the transformer part of the model and only train the embedding, adapting the newly added Chinese word vectors without disturbing the original model as much as possible.
  2. Stage Two: Use LoRA technology to add LoRA weights (adapter) to the model, and train the embedding while updating LoRA parameters.

Instruction Fine-tuning

  1. The task format of the instruction fine-tuning phase is basically the same as that of Stanford Alpaca. The training scheme also used LoRA for efficient fine-tuning and further increased the number of trainable parameters.
  2. We follow the original prompt by Stanford Alpaca that without "input". For the data that contains "input" values, we simply concatenate them in the for off"{instruction}+\n+{input}".

Training Data

During the instruction fine-tuning phase, about 2 million pieces of data were used. Details:

Dataset Size Source Description
Chinese-English Translation 500K link sampled and cleaned from original dataset
pCLUE 300K link sampled and cleaned from original dataset
Stanford Alpaca data 50K link Original training data of Stanford Alpaca
Stanford Alpaca data (Chinese) 50K Provided in our proj => link We translate original data into Chinese using ChatGPT
Self-instruction data ~1M N/A We use ChatGPT API to get these data, see below

[New] This project provides a script script/crawl_prompt.py for dynamically generating prompts of different domains and instruction types.

python script/crawl_prompt.py output-file
  • The idea is similar to the approach used in Stanford Alpaca. It generates 20 sets of data at a time (you can modify the templates), reducing the cost of crawling.
  • The generated file contains data crawled through gpt-3.5-turbo (you must have an OpenAI API key to use it).
  • Although the instruction template requires the output to be in JSON format, the system does not always return valid JSON, so you need to clean it up according to the returned data.
  • Since crawling takes a long time, it is recommended to run this script in the background. When running multiple threads, pay attention to the call limit of the OpenAI API.

Limitations

Although the models in this project have significantly improved Chinese understanding and generation capabilities compared to the original LLaMA and Alpaca, there are also the following limitations:

  • It may produce unpredictable harmful content and content that does not conform to human preferences and values.
  • Due to computing power and data issues, the training of the related models is not sufficient, and the Chinese understanding ability needs to be further improved.
  • There is no online interactive demo available for now (Note: users can still deploy it locally themselves).

FAQ

Q1: Why can't you release the complete model weights?

A: This question has been emphasized repeatedly before. The open source license for the LLaMA model does not allow us to do so, so related derivative work is seeking ways to bypass the restrictions. Please believe that we set up so many steps not to increase everyone's workload, but because of objective circumstances. After Facebook fully opens up the weights, we will release the complete model and directly loadable quantized models as soon as possible. During this period, we will also closely monitor other LLaMA-related repositories to see if there are better methods.

Q2: Will there be versions of 13B, 33B, and 65B in the future?

A: We cannot guarantee this at this time.

Q3: The model doesn't perform well on some tasks!

A: There are several possible reasons: 1) LLaMA itself has limited support for Chinese, and most related derivative work is pre-trained/finetuned directly on the original version, while we have taken a more bold strategy - expanding the Chinese vocabulary, which may further exacerbate the problem of insufficient Chinese training, but whether it is beneficial for subsequent pre-training in the long run remains to be seen over time; 2) the quality of instruction data needs to be further improved; 3) there is still a lot of room for adjustment in training time, hyperparameters, etc.; 4) there is no RLHF; 5) the Q4 quantization may cause a decrease in performance, so you can try loading the FP16 model, which is relatively better (but slower).

Q4: Why expand the vocabulary? Can't you just pre-train the original LLaMA with Chinese data?

A: The original LLaMA model's vocabulary size is 32K, mainly trained on English (see the LLaMA paper for more details), and support for multiple languages is not particularly ideal (you can compare the vocabulary size of the multilingual classic model XLM-R, which is 250K). Preliminary statistics show that the LLaMA vocabulary contains very few Chinese characters, so when cutting the words, the Chinese words are cut into smaller pieces, requiring multiple byte tokens to form a complete Chinese character, which leads to a decrease in information density. For example, in the model with the expanded vocabulary, a single Chinese character tends to be cut into one token, while in the original LLaMA, it may require 2-3 tokens to combine into one Chinese character, significantly reducing the efficiency of encoding and decoding.
