Introduction

ChatGLM-6B is an open bilingual language model based on General Language Model (GLM) framework, with 6.2 billion parameters. With the quantization technique, users can deploy locally on consumer-grade graphics cards (only 6GB of GPU memory is required at the INT4 quantization level).

ChatGLM-6B uses technology similar to ChatGPT, optimized for Chinese QA and dialogue. The model is trained for about 1T tokens of Chinese and English corpus, supplemented by supervised fine-tuning, feedback bootstrap, and reinforcement learning wit human feedback. With only about 6.2 billion parameters, the model is able to generate answers that are in line with human preference.

In order to facilitate downstream developers to customize the model for their own application scenarios, we also implements an parameter-efficient tuning method based on P-Tuning v2 (Guidelines). Tuning requires at least 7GB of GPU memory at INT4 quantization level.

Getting Started

Hardware Requirements

Quantization Level	GPU Memory
FP16（no quantization）	13 GB
INT8	10 GB
INT4	6 GB

Environment Setup

Install the requirements with pip: pip install -r requirements.txt. transformers library version is recommended to be 4.27.1, but theoretically any version no lower than 4.23.1 is acceptable.

In addition, if you need to run the quantified model on the CPU, you also need to install gcc and openmp. Most Linux distributions are installed by default. For Windows, you can check openmp when installing TDM-GCC. On Windows testing environment, the gcc version is TDM-GCC 10.3.0, and on Linux is gcc 11.3.0.

Usage

Generate dialogue with the following code

>>> from transformers import AutoTokenizer, AutoModel
>>> tokenizer = AutoTokenizer.from_pretrained("THUDM/chatglm-6b", trust_remote_code=True)
>>> model = AutoModel.from_pretrained("THUDM/chatglm-6b", trust_remote_code=True).half().cuda()
>>> model = model.eval()
>>> response, history = model.chat(tokenizer, "你好", history=[])
>>> print(response)
你好👋!我是人工智能助手 ChatGLM-6B,很高兴见到你,欢迎问我任何问题。
>>> response, history = model.chat(tokenizer, "晚上睡不着应该怎么办", history=history)
>>> print(response)
晚上睡不着可能会让你感到焦虑或不舒服,但以下是一些可以帮助你入睡的方法:

4. 避免饮用含有咖啡因的饮料:咖啡因是一种刺激性物质,会影响你的睡眠质量。尽量避免在睡前饮用含有咖啡因的饮料,例如咖啡,茶和可乐。
5. 避免在床上做与睡眠无关的事情:在床上做些与睡眠无关的事情,例如看电影,玩游戏或工作等,可能会干扰你的睡眠。
6. 尝试呼吸技巧:深呼吸是一种放松技巧,可以帮助你缓解紧张和焦虑,使你更容易入睡。试着慢慢吸气,保持几秒钟,然后缓慢呼气。

如果这些方法无法帮助你入睡,你可以考虑咨询医生或睡眠专家,寻求进一步的建议。

The implementation of the model is still in development. If you want to fix the used model implementation to ensure compatibility, you can add the revision="v1.1.0" parameter in the from_pretrained call. v1.1.0 is the latest version number. For a complete list of versions, see Change Log.

Load the model locally

The above code will automatically download the model implementation and checkpoints by transformers. The full model implementation can be found at Hugging Face Hub. If your network environment is poor, downloading model parameters may take a long time or even fail. At this point, you can download the model to the local first, and then load it from the local.

To download models from Hugging Face Hub, you need to install Git LFS , then run

git clone https://huggingface.co/THUDM/chatglm-6b

After downloading the model locally, replace THUDM/chatglm-6b in the above code with the path of your local chatglm-6b folder to load the model locally.

Optional: The implementation of the model is still in development. If you want to fix the used model implementation to ensure compatibility, you can execute

git checkout v1.1.0

Demo & API

We provide a Web demo based on Gradio and a command line demo in the repo. First clone our repo with:

git clone https://github.com/THUDM/ChatGLM-6B
cd ChatGLM-6B

Web Demo

Install Gradio pip install gradio，and run web_demo.py:

python web_demo.py

The program runs a web server and outputs the URL. Open the URL in the browser to use the web demo.

Thanks to @AdamBear for implementing a web demo based on Streamlit, see #117.

CLI Demo

Run cli_demo.py in the repo:

python cli_demo.py

The command runs an interactive program in the shell. Type your instruction in the shell and hit enter to generate the response. Type clear to clear the dialogue history and stop to terminate the program.

API Deployment

First install the additional dependency pip install fastapi uvicorn. The run api.py in the repo.

python api.py

By default the api runs at the8000port of the local machine. You can call the API via

curl -X POST "http://127.0.0.1:8000" \
     -H 'Content-Type: application/json' \
     -d '{"prompt": "你好", "history": []}'

The returned value is

{
  "response":"你好👋！我是人工智能助手 ChatGLM-6B，很高兴见到你，欢迎问我任何问题。",
  "history":[["你好","你好👋！我是人工智能助手 ChatGLM-6B，很高兴见到你，欢迎问我任何问题。"]],
  "status":200,
  "time":"2023-03-23 21:38:40"
}

Deployment

Quantization

By default, the model parameters are loaded with FP16 precision, which require about 13GB of GPU memory. It your GPU memory is limited, you can try to load the model parameters with quantization:

# Change according to your hardware. Only support 4/8 bit quantization now.
model = AutoModel.from_pretrained("THUDM/chatglm-6b", trust_remote_code=True).half().quantize(8).cuda()

After 2 to 3 rounds of dialogue, the GPU memory usage is about 10GB under 8-bit quantization, and only 6GB under 4-bit quantization. As the number of dialogue rounds increases, the corresponding GPU memory consumption also increases. Due to the use of relative position encoding, ChatGLM-6B theoretically supports an infinitely long context-length, but the performance will gradually decline after the total length exceeds 2048 (training length).

Model quantization brings a certain performance decline. After testing, ChatGLM-6B can still perform natural and smooth generation under 4-bit quantization. using GPT-Q etc. The quantization scheme can further compress the quantization accuracy/improve the model performance under the same quantization accuracy. You are welcome to submit corresponding Pull Requests.

The quantization costs about 13GB of CPU memory to load the FP16 model. If your CPU memory is limited, you can directly load the quantized model, which costs only 5.2GB CPU memory:

# For INT8-quantized model, change "chatglm-6b-int4" to "chatglm-6b-int8"
model = AutoModel.from_pretrained("THUDM/chatglm-6b-int4", trust_remote_code=True).half().cuda()

CPU Deployment

If your computer is not equipped with GPU, you can also conduct inference on CPU, but the inference speed is slow (and taking about 32GB of memory):

model = AutoModel.from_pretrained("THUDM/chatglm-6b", trust_remote_code=True).float()

If your CPU memory is limited, you can directly load the quantized model:

# For INT8-quantized model, change "chatglm-6b-int4" to "chatglm-6b-int8"
model = AutoModel.from_pretrained("THUDM/chatglm-6b-int4", trust_remote_code=True).float()

If your encounter the error Could not find module 'nvcuda.dll' or RuntimeError: Unknown platform: darwin(MacOS), please load the model locally.

Inference on Mac

For Macs (and MacBooks) with Apple Silicon, it is possible to use the MPS backend to run ChatGLM-6B on the GPU. First, you need to refer to Apple's official instructions to install PyTorch-Nightly. (The correct version number should be 2.1.0.dev2023xxxx, not 2.0.0).

Currently you must load the model locally on MacOS. Change the code to load the model from your local path, and use the mps backend:

model = AutoModel.from_pretrained("your local path", trust_remote_code=True).half().to('mps')

Loading a FP16 ChatGLM-6B model requires about 13GB of memory. Machines with less memory (such as a MacBook Pro with 16GB of memory) will use the virtual memory on the hard disk when there is insufficient free memory, resulting in a serious slowdown in inference speed. At this time, a quantized model such as chatglm-6b-int4 can be used. Because the quantized kernel on the GPU is written in CUDA, it cannot be used on MacOS, and can only be inferred using the CPU:

# For INT8-quantized model, change "chatglm-6b-int4" to "chatglm-6b-int8"
model = AutoModel.from_pretrained("THUDM/chatglm-6b-int4", trust_remote_code=True).float()

Multi-GPU Deployment

If you have multiple GPUs, but the memory size of each GPU is not sufficient to accommodate the entire model, you can split the model across multiple GPUs.

First, install accelerate: pip install accelerate, and then load the model using the following method:

from utils import load_model_on_gpus
model = load_model_on_gpus("THUDM/chatglm-6b", num_gpus=2)

This will deploy the model onto two GPUs for inference. You can change num_gpus to the number of GPUs you want to use. By default, the model is split evenly, but you can also specify the device_map parameter to customize the splitting.

Parameter-efficient Tuning

Parameter-efficient tuning based on P-tuning v2. See ptuning/README.md for details on how to use it.
