* Platforms: Linux, MacOS, Windows

* Models: [ChatGLM-6B](https://github.com/THUDM/ChatGLM-6B), [ChatGLM2-6B](https://github.com/THUDM/ChatGLM2-6B), [ChatGLM3](https://github.com/THUDM/ChatGLM3), [GLM-4](https://github.com/THUDM/GLM-4)(V), [CodeGeeX2](https://github.com/THUDM/CodeGeeX2)



## Getting Started



**Preparation**



Clone the ChatGLM.cpp repository into your local machine:

```sh

git clone --recursive https://github.com/li-plus/chatglm.cpp.git && cd chatglm.cpp

```



If you forgot the `--recursive` flag when cloning the repository, run the following command in the `chatglm.cpp` folder:

```sh

git submodule update --init --recursive

```



**Quantize Model**



Install necessary packages for loading and quantizing Hugging Face models:

```sh

python3 -m pip install -U pip

python3 -m pip install torch tabulate tqdm transformers accelerate sentencepiece

```



Use `convert.py` to transform ChatGLM-6B into quantized GGML format. For example, to convert the fp16 original model to q4_0 (quantized int4) GGML model, run:

```sh

python3 chatglm_cpp/convert.py -i THUDM/chatglm-6b -t q4_0 -o models/chatglm-ggml.bin

```



The original model (`-i `) can be a Hugging Face model name or a local path to your pre-downloaded model. Currently supported models are:

* ChatGLM-6B: `THUDM/chatglm-6b`, `THUDM/chatglm-6b-int8`, `THUDM/chatglm-6b-int4`

* ChatGLM2-6B: `THUDM/chatglm2-6b`, `THUDM/chatglm2-6b-int4`, `THUDM/chatglm2-6b-32k`, `THUDM/chatglm2-6b-32k-int4`

* ChatGLM3-6B: `THUDM/chatglm3-6b`, `THUDM/chatglm3-6b-32k`, `THUDM/chatglm3-6b-128k`, `THUDM/chatglm3-6b-base`

* ChatGLM4(V)-9B: `THUDM/glm-4-9b-chat`, `THUDM/glm-4-9b-chat-1m`, `THUDM/glm-4-9b`, `THUDM/glm-4v-9b`

* CodeGeeX2: `THUDM/codegeex2-6b`, `THUDM/codegeex2-6b-int4`



You are free to try any of the below quantization types by specifying `-t `:

| type   | precision | symmetric |

| ------ | --------- | --------- |

| `q4_0` | int4      | true      |

| `q4_1` | int4      | false     |

| `q5_0` | int5      | true      |

| `q5_1` | int5      | false     |

| `q8_0` | int8      | true      |

| `f16`  | half      |           |

| `f32`  | float     |           |



For LoRA models, add `-l ` flag to merge your LoRA weights into the base model. For example, run `python3 chatglm_cpp/convert.py -i THUDM/chatglm3-6b -t q4_0 -o models/chatglm3-ggml-lora.bin -l shibing624/chatglm3-6b-csc-chinese-lora` to merge public LoRA weights from Hugging Face.



For P-Tuning v2 models using the [official finetuning script](https://github.com/THUDM/ChatGLM3/tree/main/finetune_demo), additional weights are automatically detected by `convert.py`. If `past_key_values` is on the output weight list, the P-Tuning checkpoint is successfully converted.



**Build & Run**



Compile the project using CMake:

```sh

cmake -B build

cmake --build build -j --config Release

```



Now you may chat with the quantized ChatGLM-6B model by running:

```sh

./build/bin/main -m models/chatglm-ggml.bin -p 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。

```



To run the model in interactive mode, add the `-i` flag. For example:

```sh

./build/bin/main -m models/chatglm-ggml.bin -i

```

In interactive mode, your chat history will serve as the context for the next-round conversation.



Run `./build/bin/main -h` to explore more options!

ChatGLM4-9B



Chat mode:

```sh

python3 chatglm_cpp/convert.py -i THUDM/glm-4-9b-chat -t q4_0 -o models/chatglm4-ggml.bin

./build/bin/main -m models/chatglm4-ggml.bin -p 你好 --top_p 0.8 --temp 0.8

# 你好👋！有什么可以帮助你的吗？

```



ChatGLM4V-9B



[![03-Confusing-Pictures](examples/03-Confusing-Pictures.jpg)](https://www.barnorama.com/wp-content/uploads/2016/12/03-Confusing-Pictures.jpg)



You may use `-vt ` to set quantization type for the vision encoder. It is recommended to run GLM4V on GPU since vision encoding runs too slow on CPU even with 4-bit quantization.

```sh

python3 chatglm_cpp/convert.py -i THUDM/glm-4v-9b -t q4_0 -vt q4_0 -o models/chatglm4v-ggml.bin

./build/bin/main -m models/chatglm4v-ggml.bin --image examples/03-Confusing-Pictures.jpg -p "这张图片有什么不寻常的地方" --temp 0

# 这张图片中不寻常的地方在于，男子正在一辆黄色出租车后面熨衣服。通常情况下，熨衣是在家中或洗衣店进行的，而不是在车辆上。此外，出租车在行驶中，男子却能够稳定地熨衣，这增加了场景的荒诞感。

```



CodeGeeX2



```sh

$ python3 chatglm_cpp/convert.py -i THUDM/codegeex2-6b -t q4_0 -o models/codegeex2-ggml.bin

$ ./build/bin/main -m models/codegeex2-ggml.bin --temp 0 --mode generate -p "\

# language: Python

# write a bubble sort function

"



def bubble_sort(lst):

    for i in range(len(lst) - 1):

        for j in range(len(lst) - 1 - i):

            if lst[j] > lst[j + 1]:

                lst[j], lst[j + 1] = lst[j + 1], lst[j]

    return lst



print(bubble_sort([5, 4, 3, 2, 1]))

```



## Using BLAS



BLAS library can be integrated to further accelerate matrix multiplication. However, in some cases, using BLAS may cause performance degradation. Whether to turn on BLAS should depend on the benchmarking result.



**Accelerate Framework**



Accelerate Framework is automatically enabled on macOS. To disable it, add the CMake flag `-DGGML_NO_ACCELERATE=ON`.



**OpenBLAS**



OpenBLAS provides acceleration on CPU. Add the CMake flag `-DGGML_OPENBLAS=ON` to enable it.

```sh

cmake -B build -DGGML_OPENBLAS=ON && cmake --build build -j

```



**CUDA**



CUDA accelerates model inference on NVIDIA GPU. Add the CMake flag `-DGGML_CUDA=ON` to enable it.

```sh

cmake -B build -DGGML_CUDA=ON && cmake --build build -j

```



By default, all kernels will be compiled for all possible CUDA architectures and it takes some time. To run on a specific type of device, you may specify `CMAKE_CUDA_ARCHITECTURES` to speed up the nvcc compilation. For example:

```sh

cmake -B build -DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES="80"       # for A100

cmake -B build -DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES="70;75"    # compatible with both V100 and T4

```



To find out the CUDA architecture of your GPU device, see [Your GPU Compute Capability](https://developer.nvidia.com/cuda-gpus).



**Metal**



MPS (Metal Performance Shaders) allows computation to run on powerful Apple Silicon GPU. Add the CMake flag `-DGGML_METAL=ON` to enable it.

```sh

cmake -B build -DGGML_METAL=ON && cmake --build build -j

```



## Python Binding



The Python binding provides high-level `chat` and `stream_chat` interface similar to the original Hugging Face ChatGLM(2)-6B.



**Installation**



Install from PyPI (recommended): will trigger compilation on your platform.

```sh

pip install -U chatglm-cpp

```



To enable CUDA on NVIDIA GPU:

```sh

CMAKE_ARGS="-DGGML_CUDA=ON" pip install -U chatglm-cpp

```



To enable Metal on Apple silicon devices:

```sh

CMAKE_ARGS="-DGGML_METAL=ON" pip install -U chatglm-cpp

```



You may also install from source. Add the corresponding `CMAKE_ARGS` for acceleration.

```sh

# install from the latest source hosted on GitHub

pip install git+https://github.com/li-plus/chatglm.cpp.git@main

# or install from your local source after git cloning the repo

pip install .

```



Pre-built wheels for CPU backend on Linux / MacOS / Windows are published on [release](https://github.com/li-plus/chatglm.cpp/releases). For CUDA / Metal backends, please compile from source code or source distribution.



**Using Pre-converted GGML Models**



Here is a simple demo that uses `chatglm_cpp.Pipeline` to load the GGML model and chat with it. First enter the examples folder (`cd examples`) and launch a Python interactive shell:

```python

>>> import chatglm_cpp

>>> 

>>> pipeline = chatglm_cpp.Pipeline("../models/chatglm-ggml.bin")

>>> pipeline.chat([chatglm_cpp.ChatMessage(role="user", content="你好")])

ChatMessage(role="assistant", content="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。", tool_calls=[])

```



To chat in stream, run the below Python example:

```sh

python3 cli_demo.py -m ../models/chatglm-ggml.bin -i

```



Launch a web demo to chat in your browser:

```sh

python3 web_demo.py -m ../models/chatglm-ggml.bin

```



![web_demo](docs/web_demo.jpg)



For other models:



ChatGLM2-6B



```sh

python3 cli_demo.py -m ../models/chatglm2-ggml.bin -p 你好 --temp 0.8 --top_p 0.8  # CLI demo

python3 web_demo.py -m ../models/chatglm2-ggml.bin --temp 0.8 --top_p 0.8  # web demo

```



ChatGLM3-6B



**CLI Demo**



Chat mode:

```sh

python3 cli_demo.py -m ../models/chatglm3-ggml.bin -p 你好 --temp 0.8 --top_p 0.8

```



Function call:

```sh

python3 cli_demo.py -m ../models/chatglm3-ggml.bin --temp 0.8 --top_p 0.8 --sp system/function_call.txt -i

```



Code interpreter:

```sh

python3 cli_demo.py -m ../models/chatglm3-ggml.bin --temp 0.8 --top_p 0.8 --sp system/code_interpreter.txt -i

```



**Web Demo**



Install Python dependencies and the IPython kernel for code interpreter.

```sh

pip install streamlit jupyter_client ipython ipykernel

ipython kernel install --name chatglm3-demo --user

```



Launch the web demo:

```sh

streamlit run chatglm3_demo.py

```

**Converting Hugging Face LLMs at Runtime**



Sometimes it might be inconvenient to convert and save the intermediate GGML models beforehand. Here is an option to directly load from the original Hugging Face model, quantize it into GGML models in a minute, and start serving. All you need is to replace the GGML model path with the Hugging Face model name or path.

```python

>>> import chatglm_cpp

>>> 

>>> pipeline = chatglm_cpp.Pipeline("THUDM/chatglm-6b", dtype="q4_0")

Loading checkpoint shards: 100%|██████████████████████████████████| 8/8 [00:10<00:00,  1.27s/it]

Processing model states: 100%|████████████████████████████████| 339/339 [00:23<00:00, 14.73it/s]

...

>>> pipeline.chat([chatglm_cpp.ChatMessage(role="user", content="你好")])

ChatMessage(role="assistant", content="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。", tool_calls=[])

```



Likewise, replace the GGML model path with Hugging Face model in any example script, and it just works. For example:

```sh

python3 cli_demo.py -m THUDM/chatglm-6b -p 你好 -i

```



## API Server



We support various kinds of API servers to integrate with popular frontends. Extra dependencies can be installed by:

```sh

pip install 'chatglm-cpp[api]'

```

Remember to add the corresponding `CMAKE_ARGS` to enable acceleration.



**LangChain API**



Start the api server for LangChain:

```sh

MODEL=./models/chatglm2-ggml.bin uvicorn chatglm_cpp.langchain_api:app --host 127.0.0.1 --port 8000

```



Test the api endpoint with `curl`:

```sh

curl http://127.0.0.1:8000 -H 'Content-Type: application/json' -d '{"prompt": "你好"}'

```



Run with LangChain:

```python

>>> from langchain.llms import ChatGLM

>>> 

>>> llm = ChatGLM(endpoint_url="http://127.0.0.1:8000")

>>> llm.predict("你好")

'你好👋！我是人工智能助手 ChatGLM2-6B，很高兴见到你，欢迎问我任何问题。'

```



For more options, please refer to [examples/langchain_client.py](examples/langchain_client.py) and [LangChain ChatGLM Integration](https://python.langchain.com/docs/integrations/llms/chatglm).



**OpenAI API**



Start an API server compatible with [OpenAI chat completions protocol](https://platform.openai.com/docs/api-reference/chat):

```sh

MODEL=./models/chatglm3-ggml.bin uvicorn chatglm_cpp.openai_api:app --host 127.0.0.1 --port 8000

```



Test your endpoint with `curl`:

```sh

curl http://127.0.0.1:8000/v1/chat/completions -H 'Content-Type: application/json' \

    -d '{"messages": [{"role": "user", "content": "你好"}]}'

```



Use the OpenAI client to chat with your model:

```python

>>> from openai import OpenAI

>>> 

>>> client = OpenAI(base_url="http://127.0.0.1:8000/v1")

>>> response = client.chat.completions.create(model="default-model", messages=[{"role": "user", "content": "你好"}])

>>> response.choices[0].message.content

'你好👋！我是人工智能助手 ChatGLM3-6B，很高兴见到你，欢迎问我任何问题。'

```



For stream response, check out the example client script:

```sh

python3 examples/openai_client.py --base_url http://127.0.0.1:8000/v1 --stream --prompt 你好

```



Tool calling is also supported:

```sh

python3 examples/openai_client.py --base_url http://127.0.0.1:8000/v1 --tool_call --prompt 上海天气怎么样

```



Request GLM4V with image inputs:

```sh

# request with local image file

python3 examples/openai_client.py --base_url http://127.0.0.1:8000/v1 --prompt "描述这张图片" \

    --image examples/03-Confusing-Pictures.jpg --temp 0

# request with image url

python3 examples/openai_client.py --base_url http://127.0.0.1:8000/v1 --prompt "描述这张图片" \

    --image https://www.barnorama.com/wp-content/uploads/2016/12/03-Confusing-Pictures.jpg --temp 0

```



With this API server as backend, ChatGLM.cpp models can be seamlessly integrated into any frontend that uses OpenAI-style API, including [mckaywrigley/chatbot-ui](https://github.com/mckaywrigley/chatbot-ui), [fuergaosi233/wechat-chatgpt](https://github.com/fuergaosi233/wechat-chatgpt), [Yidadaa/ChatGPT-Next-Web](https://github.com/Yidadaa/ChatGPT-Next-Web), and more.



## Using Docker



**Option 1: Building Locally**



Building docker image locally and start a container to run inference on CPU:

```sh

docker build . --network=host -t chatglm.cpp

# cpp demo

docker run -it --rm -v $PWD/models:/chatglm.cpp/models chatglm.cpp ./build/bin/main -m models/chatglm-ggml.bin -p "你好"

# python demo

docker run -it --rm -v $PWD/models:/chatglm.cpp/models chatglm.cpp python3 examples/cli_demo.py -m models/chatglm-ggml.bin -p "你好"

# langchain api server

docker run -it --rm -v $PWD/models:/chatglm.cpp/models -p 8000:8000 -e MODEL=models/chatglm-ggml.bin chatglm.cpp \

    uvicorn chatglm_cpp.langchain_api:app --host 0.0.0.0 --port 8000

# openai api server

docker run -it --rm -v $PWD/models:/chatglm.cpp/models -p 8000:8000 -e MODEL=models/chatglm-ggml.bin chatglm.cpp \

    uvicorn chatglm_cpp.openai_api:app --host 0.0.0.0 --port 8000

```



For CUDA support, make sure [nvidia-docker](https://github.com/NVIDIA/nvidia-docker) is installed. Then run:

```sh

docker build . --network=host -t chatglm.cpp-cuda \

    --build-arg BASE_IMAGE=nvidia/cuda:12.2.0-devel-ubuntu20.04 \

    --build-arg CMAKE_ARGS="-DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=80"

docker run -it --rm --gpus all -v $PWD/models:/chatglm.cpp/models chatglm.cpp-cuda \

    ./build/bin/main -m models/chatglm-ggml.bin -p "你好"

```



**Option 2: Using Pre-built Image**



The pre-built image for CPU inference is published on both [Docker Hub](https://hub.docker.com/repository/docker/liplusx/chatglm.cpp) and [GitHub Container Registry (GHCR)](https://github.com/li-plus/chatglm.cpp/pkgs/container/chatglm.cpp).



To pull from Docker Hub and run demo:

```sh

docker run -it --rm -v $PWD/models:/chatglm.cpp/models liplusx/chatglm.cpp:main \

    ./build/bin/main -m models/chatglm-ggml.bin -p "你好"

```



To pull from GHCR and run demo:

```sh

docker run -it --rm -v $PWD/models:/chatglm.cpp/models ghcr.io/li-plus/chatglm.cpp:main \

    ./build/bin/main -m models/chatglm-ggml.bin -p "你好"

```



Python demo and API servers are also supported in pre-built image. Use it in the same way as **Option 1**.

## Model Quality



We measure model quality by evaluating the perplexity over the WikiText-2 test dataset, following the strided sliding window strategy in https://huggingface.co/docs/transformers/perplexity. Lower perplexity usually indicates a better model.



Download and unzip the dataset from [link](https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-2-raw-v1.zip). Measure the perplexity with a stride of 512 and max input length of 2048:

```sh

./build/bin/perplexity -m models/chatglm3-base-ggml.bin -f wikitext-2-raw/wiki.test.raw -s 512 -l 2048

```

## Development



**Unit Test & Benchmark**



To perform unit tests, add this CMake flag `-DCHATGLM_ENABLE_TESTING=ON` to enable testing. Recompile and run the unit test (including benchmark).

```sh

mkdir -p build && cd build

cmake .. -DCHATGLM_ENABLE_TESTING=ON && make -j

./bin/chatglm_test

```



For benchmark only:

```sh

./bin/chatglm_test --gtest_filter='Benchmark.*'

```



**Lint**



To format the code, run `make lint` inside the `build` folder. You should have `clang-format`, `black` and `isort` pre-installed.



**Performance**



To detect the performance bottleneck, add the CMake flag `-DGGML_PERF=ON`:

```sh

cmake .. -DGGML_PERF=ON && make -j

```

This will print timing for each graph operation when running the model.
