ChatGLM-6B is an open bilingual language model based on [General Language Model (GLM)](https://github.com/THUDM/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](https://github.com/THUDM/P-tuning-v2)[(Guidelines)](ptuning/README_en.md). Tuning requires at least 7GB of GPU memory at INT4 quantization level.
**[2023/05/17]** Release [VisualGLM-6B](https://github.com/THUDM/VisualGLM-6B/), a multimodal conversational language model supporting image understanding.
You can run the command line and web demo through [cli_demo_vision.py](cli_demo_vision.py) and [web_demo_vision.py](web_demo_vision.py) in the repository. Note that VisualGLM-6B requires additional installation of [SwissArmyTransformer](https://github.com/THUDM/SwissArmyTransformer/) and torchvision.
**[2023/05/15]** Update the checkpoint of v1.1 version, add English instruction data for training to balance the proportion of Chinese and English data, which solves the phenomenon of Chinese words mixed in English answers .

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](https://jmeubank.github.io/tdm-gcc/). On Windows testing environment, the `gcc` version is `TDM-GCC 10.3.0`, and on Linux is `gcc 11.3.0`.
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](https://huggingface.co/THUDM/chatglm-6b#change-log).
The above code will automatically download the model implementation and checkpoints by [transformers](https://github.com/huggingface/transformers). The full model implementation can be found at [Hugging Face Hub](https://huggingface.co/THUDM/chatglm-6b). 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](https://docs.github.com/zh/repositories/working-with-files/managing-large-files/installing-git-large-file-storage) , then run
```Shell
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
Thanks to [@AdamBear](https://github.com/AdamBear) for implementing a web demo based on Streamlit, see [#117](https://github.com/THUDM/ChatGLM-6B/pull/117 ).
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.
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:
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](https://arxiv.org/abs/2210.17323) 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:
If your encounter the error `Could not find module 'nvcuda.dll'` or `RuntimeError: Unknown platform: darwin`(MacOS), please [load the model locally](README_en.md#load-the-model-locally).
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](https://developer.apple.com/metal/pytorch) 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](README_en.md#load-the-model-locally) on MacOS. Change the code to load the model from your local path, and use the mps backend:
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:
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.
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.
