<h3>Preparation</h3>
Some preparation:
- CUDA 12.1 and above, if you didn't have it yet, you may install from [here](https://developer.nvidia.com/cuda-downloads).
<!-- ```
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export CUDA_PATH=/usr/local/cuda
``` -->
- Linux-x86_64 with gcc, g++ and cmake
```sh
sudo apt-get update
sudo apt-get install gcc g++ cmake ninja-build
```
- We recommend using [Conda](https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh) to create a virtual environment with Python=3.11 to run our program.
```sh
conda create --name ktransformers python=3.11
conda activate ktransformers # you may need to run ‘conda init’ and reopen shell first
```
- Make sure that PyTorch, packaging, ninja is installed
```
pip install torch packaging ninja
```
<h3>Installation</h3>
1. Use a Docker image, see [documentation for Docker](./doc/en/docker.md)
2. You can install using Pypi (for linux):
```
pip install ktransformers --no-build-isolation
```
for windows we prepare a pre compiled whl package in [ktransformers-0.1.1+cu125torch24avx2-cp311-cp311-win_amd64.whl](https://github.com/kvcache-ai/ktransformers/releases/download/v0.1.1/ktransformers-0.1.1+cu125torch24avx2-cp311-cp311-win_amd64.whl), which require cuda-12.5, torch-2.4, python-3.11, more pre compiled package are being produced.
3. Or you can download source code and compile:
- init source code
```sh
git clone https://github.com/kvcache-ai/ktransformers.git
cd ktransformers
git submodule init
git submodule update
```
- [Optional] If you want to run with website, please [compile the website](./doc/en/api/server/website.md) before execute ```bash install.sh```
- Compile and install (for Linux)
```
bash install.sh
```
- Compile and install(for Windows)
```
install.bat
```
<h3>Local Chat</h3>
We provide a simple command-line local chat Python script that you can run for testing.
> Note that this is a very simple test tool only support one round chat without any memory about last input, if you want to try full ability of the model, you may go to [RESTful API and Web UI](#id_666). We use the DeepSeek-V2-Lite-Chat-GGUF model as an example here. But we also support other models, you can replace it with any other model that you want to test.
<h4>Run Example</h4>
```shell
# Begin from root of your cloned repo!
# Begin from root of your cloned repo!!
# Begin from root of your cloned repo!!!
# Download mzwing/DeepSeek-V2-Lite-Chat-GGUF from huggingface
mkdir DeepSeek-V2-Lite-Chat-GGUF
cd DeepSeek-V2-Lite-Chat-GGUF
wget https://huggingface.co/mzwing/DeepSeek-V2-Lite-Chat-GGUF/resolve/main/DeepSeek-V2-Lite-Chat.Q4_K_M.gguf -O DeepSeek-V2-Lite-Chat.Q4_K_M.gguf
cd .. # Move to repo's root dir
# Start local chat
python -m ktransformers.local_chat --model_path deepseek-ai/DeepSeek-V2-Lite-Chat --gguf_path ./DeepSeek-V2-Lite-Chat-GGUF
# If you see “OSError: We couldn't connect to 'https://huggingface.co' to load this file”, try：
# GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/deepseek-ai/DeepSeek-V2-Lite
# python ktransformers.local_chat --model_path ./DeepSeek-V2-Lite --gguf_path ./DeepSeek-V2-Lite-Chat-GGUF
```
It features the following arguments:
- `--model_path` (required): Name of the model (such as "deepseek-ai/DeepSeek-V2-Lite-Chat" which will automatically download configs from [Hugging Face](https://huggingface.co/deepseek-ai/DeepSeek-V2-Lite)). Or if you already got local files you may directly use that path to initialize the model.
>Note: <strong>.safetensors</strong> files are not required in the directory. We only need config files to build model and tokenizer.
- `--gguf_path` (required): Path of a directory containing GGUF files which could that can be downloaded from [Hugging Face](https://huggingface.co/mzwing/DeepSeek-V2-Lite-Chat-GGUF/tree/main) (we only support q4_k_m and q8_0 for now, more formats are coming soon).
- `--optimize_rule_path` (required except for Qwen2Moe and DeepSeek-V2): Path of YAML file containing optimize rules. There are two rule files pre-written in the [ktransformers/optimize/optimize_rules](ktransformers/optimize/optimize_rules) directory for optimizing DeepSeek-V2 and Qwen2-57B-A14, two SOTA MoE models.
- `--max_new_tokens`: Int (default=1000). Maximum number of new tokens to generate.
- `--cpu_infer`: Int (default=10). The number of CPUs used for inference. Should ideally be set to the (total number of cores - 2).

<h2 id="tutorial">📃 Brief Injection Tutorial</h2>
At the heart of KTransformers is a user-friendly, template-based injection framework.
This allows researchers to easily replace original torch modules with optimized variants. It also simplifies the process of combining multiple optimizations, allowing the exploration of their synergistic effects.
</br>
<p align="center">

</picture>
</p>
Given that vLLM already serves as a great framework for large-scale deployment optimizations, KTransformers is particularly focused on local deployments that are constrained by limited resources. We pay special attention to heterogeneous computing opportunities, such as GPU/CPU offloading of quantized models. For example, we support the efficient <a herf="https://github.com/Mozilla-Ocho/llamafile/tree/main">Llamafile</a> and <a herf="https://github.com/IST-DASLab/marlin">Marlin</a> kernels for CPU and GPU, respectively. More details can be found <a herf="doc/en/operators/llamafile.md">here</a>.
<h3>Example Usage</h3>
To utilize the provided kernels, users only need to create a YAML-based injection template and add the call to `optimize_and_load_gguf` before using the Transformers model.
```python
with torch.device("meta"):
model = AutoModelForCausalLM.from_config(config, trust_remote_code=True)
optimize_and_load_gguf(model, optimize_rule_path, gguf_path, config)
...
generated = prefill_and_generate(model, tokenizer, input_tensor.cuda(), max_new_tokens=1000)
```
In this example, the AutoModel is first initialized on the meta device to avoid occupying any memory resources. Then, `optimize_and_load_gguf` iterates through all sub-modules of the model, matches rules specified in your YAML rule file, and replaces them with advanced modules as specified.
After injection, the original `generate` interface is available, but we also provide a compatible `prefill_and_generate` method, which enables further optimizations like CUDAGraph to improve generation speed.
<h3>How to custom your model</h3>
A detailed tutorial of the injection and multi-GPU using DeepSeek-V2 as an example is given [here](doc/en/injection_tutorial.md).
Below is an example of a YAML template for replacing all original Linear modules with Marlin, an advanced 4-bit quantization kernel.
```yaml
- match:
name: "^model\\.layers\\..*$" # regular expression
class: torch.nn.Linear # only match modules matching name and class simultaneously
replace:
class: ktransformers.operators.linear.KTransformerLinear # optimized Kernel on quantized data types
device: "cpu" # which devices to load this module when initializing
kwargs:
generate_device: "cuda"
generate_linear_type: "QuantizedLinearMarlin"
```
Each rule in the YAML file has two parts: `match` and `replace`. The `match` part specifies which module should be replaced, and the `replace` part specifies the module to be injected into the model along with the initialization keywords.
You can find example rule templates for optimizing DeepSeek-V2 and Qwen2-57B-A14, two SOTA MoE models, in the [ktransformers/optimize/optimize_rules](ktransformers/optimize/optimize_rules) directory. These templates are used to power the `local_chat.py` demo.
If you are interested in our design principles and the implementation of the injection framework, please refer to the [design document](doc/en/deepseek-v2-injection.md).
<h2 id="ack">Acknowledgment and Contributors</h2>
The development of KTransformer is based on the flexible and versatile framework provided by Transformers. We also benefit from advanced kernels such as GGUF/GGML, Llamafile, and Marlin. We are planning to contribute back to the community by upstreaming our modifications.
KTransformer is actively maintained and developed by contributors from the <a href="https://madsys.cs.tsinghua.edu.cn/">MADSys group</a> at Tsinghua University and members from <a href="http://approaching.ai/">Approaching.AI</a>. We welcome new contributors to join us in making KTransformer faster and easier to use.

You can also find an example of integrating with Tabby [here](doc/en/api/server/tabby.md).\n\n\n<h2 id=\"tutorial\">\ud83d\udcc3 Brief Injection Tutorial</h2>\nAt the heart of KTransformers is a user-friendly, template-based injection framework. \nThis allows researchers to easily replace original torch modules with optimized variants. It also simplifies the process of combining multiple optimizations, allowing the exploration of their synergistic effects. \n\n</br>\n<p align=\"center\">\n <picture>\n <img alt=\"Inject-Struction\" src=\"https://github.com/user-attachments/assets/6b4c1e54-9f6d-45c5-a3fc-8fa45e7d257e\" width=65%>\n </picture>\n</p>\n\nGiven that vLLM already serves as a great framework for large-scale deployment optimizations, KTransformers is particularly focused on local deployments that are constrained by limited resources. We pay special attention to heterogeneous computing opportunities, such as GPU/CPU offloading of quantized models. For example, we support the efficient <a herf=\"https://github.com/Mozilla-Ocho/llamafile/tree/main\">Llamafile</a> and <a herf=\"https://github.com/IST-DASLab/marlin\">Marlin</a> kernels for CPU and GPU, respectively. More details can be found <a herf=\"doc/en/operators/llamafile.md\">here</a>.\n\n<h3>Example Usage</h3>\nTo utilize the provided kernels, users only need to create a YAML-based injection template and add the call to `optimize_and_load_gguf` before using the Transformers model.\n\n```python\nwith torch.device(\"meta\"):\n model = AutoModelForCausalLM.from_config(config, trust_remote_code=True)\noptimize_and_load_gguf(model, optimize_rule_path, gguf_path, config)\n...\ngenerated = prefill_and_generate(model, tokenizer, input_tensor.cuda(), max_new_tokens=1000)\n```\n\nIn this example, the AutoModel is first initialized on the meta device to avoid occupying any memory resources. Then, `optimize_and_load_gguf` iterates through all sub-modules of the model, matches rules specified in your YAML rule file, and replaces them with advanced modules as specified.\n\nAfter injection, the original `generate` interface is available, but we also provide a compatible `prefill_and_generate` method, which enables further optimizations like CUDAGraph to improve generation speed.\n\n<h3>How to custom your model</h3>\n\nA detailed tutorial of the injection and multi-GPU using DeepSeek-V2 as an example is given [here](doc/en/injection_tutorial.md).\n\nBelow is an example of a YAML template for replacing all original Linear modules with Marlin, an advanced 4-bit quantization kernel.\n\n```yaml\n- match:\n name: \"^model\\\\.layers\\\\..*$\" # regular expression \n class: torch.nn.Linear # only match modules matching name and class simultaneously\n replace:\n class: ktransformers.operators.linear.KTransformerLinear # optimized Kernel on quantized data types\n device: \"cpu\" # which devices to load this module when initializing\n kwargs:\n generate_device: \"cuda\"\n generate_linear_type: \"QuantizedLinearMarlin\"\n```\n\nEach rule in the YAML file has two parts: `match` and `replace`. The `match` part specifies which module should be replaced, and the `replace` part specifies the module to be injected into the model along with the initialization keywords.\n\nYou can find example rule templates for optimizing DeepSeek-V2 and Qwen2-57B-A14, two SOTA MoE models, in the [ktransformers/optimize/optimize_rules](ktransformers/optimize/optimize_rules) directory. These templates are used to power the `local_chat.py` demo.\n\nIf you are interested in our design principles and the implementation of the injection framework, please refer to the [design document](doc/en/deepseek-v2-injection.md).\n\n<h2 id=\"ack\">Acknowledgment and Contributors</h2>\n\nThe development of KTransformer is based on the flexible and versatile framework provided by Transformers. We also benefit from advanced kernels such as GGUF/GGML, Llamafile, and Marlin. We are planning to contribute back to the community by upstreaming our modifications.\n\nKTransformer is actively maintained and developed by contributors from the <a href=\"https://madsys.cs.tsinghua.edu.cn/\">MADSys group</a> at Tsinghua University and members from <a href=\"http://approaching.ai/\">Approaching.AI</a>. We welcome new contributors to join us in making KTransformer faster and easier to use.\n",
