## Description
2024-02-05 14:55:10 +00:00
The main goal of `llama.cpp` is to enable LLM inference with minimal setup and state-of-the-art performance on a wide
variety of hardware - locally and in the cloud.
2023-03-10 19:47:46 +00:00
2024-02-05 14:55:10 +00:00
- Plain C/C++ implementation without any dependencies
- Apple silicon is a first-class citizen - optimized via ARM NEON, Accelerate and Metal frameworks
2023-05-05 14:43:36 +00:00
- AVX, AVX2 and AVX512 support for x86 architectures
2024-02-19 07:39:31 +00:00
- 1.5-bit, 2-bit, 3-bit, 4-bit, 5-bit, 6-bit, and 8-bit integer quantization for faster inference and reduced memory use
2024-02-05 14:55:10 +00:00
- Custom CUDA kernels for running LLMs on NVIDIA GPUs (support for AMD GPUs via HIP)
- Vulkan, SYCL, and (partial) OpenCL backend support
- CPU+GPU hybrid inference to partially accelerate models larger than the total VRAM capacity
2023-03-10 19:47:46 +00:00
2024-02-05 14:55:10 +00:00
Since its [inception ](https://github.com/ggerganov/llama.cpp/issues/33#issuecomment-1465108022 ), the project has
improved significantly thanks to many contributions. It is the main playground for developing new features for the
[ggml ](https://github.com/ggerganov/ggml ) library.

Building a website can be done in 10 simple steps:
Step 1: Find the right website platform.
Step 2: Choose your domain name and hosting plan.
Step 3: Design your website layout.
Step 4: Write your website content and add images.
Step 5: Install security features to protect your site from hackers or spammers
Step 6: Test your website on multiple browsers, mobile devices, operating systems etc…
Step 7: Test it again with people who are not related to you personally – friends or family members will work just fine!
Step 8: Start marketing and promoting the website via social media channels or paid ads
Step 9: Analyze how many visitors have come to your site so far, what type of people visit more often than others (e.g., men vs women) etc…
Step 10: Continue to improve upon all aspects mentioned above by following trends in web design and staying up-to-date on new technologies that can enhance user experience even further!
How does a Website Work?
A website works by having pages, which are made of HTML code. This code tells your computer how to display the content on each page you visit – whether it’ s an image or text file (like PDFs). In order for someone else’ s browser not only be able but also want those same results when accessing any given URL; some additional steps need taken by way of programming scripts that will add functionality such as making links clickable!
The most common type is called static HTML pages because they remain unchanged over time unless modified manually (either through editing files directly or using an interface such as WordPress). They are usually served up via HTTP protocols – this means anyone can access them without having any special privileges like being part of a group who is allowed into restricted areas online; however, there may still exist some limitations depending upon where one lives geographically speaking.

## Usage
2024-02-07 06:21:30 +00:00
Here are the end-to-end binary build and model conversion steps for most supported models.
2023-04-13 13:43:22 +00:00
### Get the Code
2023-03-11 08:47:09 +00:00
2023-03-10 19:47:46 +00:00
```bash
git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
2023-04-13 13:43:22 +00:00
```
### Build
2023-04-26 20:03:03 +00:00
In order to build llama.cpp you have three different options.
2023-04-13 13:43:22 +00:00
2023-04-26 20:03:03 +00:00
- Using `make` :
- On Linux or MacOS:
2023-04-13 13:43:22 +00:00
2023-04-26 20:03:03 +00:00
```bash
make
```
- On Windows:
2023-04-28 14:22:48 +00:00
1. Download the latest fortran version of [w64devkit ](https://github.com/skeeto/w64devkit/releases ).
2023-04-26 20:03:03 +00:00
2. Extract `w64devkit` on your pc.
3. Run `w64devkit.exe` .
4. Use the `cd` command to reach the `llama.cpp` folder.
5. From here you can run:
```bash
make
```
2023-03-10 19:47:46 +00:00
2023-04-26 20:03:03 +00:00
- Using `CMake` :
2023-04-05 14:36:12 +00:00
2023-04-13 13:43:22 +00:00
```bash
mkdir build
cd build
cmake ..
cmake --build . --config Release
```
2023-08-17 20:11:18 +00:00
- Using `Zig` (version 0.11 or later):
Building for optimization levels and CPU features can be accomplished using standard build arguments, for example AVX2, FMA, F16C,
it's also possible to cross compile for other operating systems and architectures:
2023-04-13 13:43:22 +00:00
```bash
2023-08-17 20:11:18 +00:00
zig build -Doptimize=ReleaseFast -Dtarget=x86_64-windows-gnu -Dcpu=x86_64+avx2+fma+f16c
2023-04-13 13:43:22 +00:00
```
2023-08-17 20:11:18 +00:00
The `zig targets` command will give you valid options to use.
2023-07-23 11:52:08 +00:00
- Using `gmake` (FreeBSD):
1. Install and activate [DRM in FreeBSD ](https://wiki.freebsd.org/Graphics )
2. Add your user to **video** group
3. Install compilation dependencies.
```bash
sudo pkg install gmake automake autoconf pkgconf llvm15 clinfo clover \
opencl clblast openblas
2024-01-30 09:16:38 +00:00
gmake CC=/usr/local/bin/clang15 CXX=/usr/local/bin/clang++15 -j4
2023-07-23 11:52:08 +00:00
```
**Notes:** With this packages you can build llama.cpp with OPENBLAS and
CLBLAST support for use OpenCL GPU acceleration in FreeBSD. Please read
the instructions for use and activate this options in this document below.
2023-06-04 20:34:30 +00:00
### Metal Build
2023-09-04 19:26:24 +00:00
On MacOS, Metal is enabled by default. Using Metal makes the computation run on the GPU.
To disable the Metal build at compile time use the `LLAMA_NO_METAL=1` flag or the `LLAMA_METAL=OFF` cmake option.
2023-06-04 20:34:30 +00:00
2023-10-12 11:10:50 +00:00
When built with Metal support, you can explicitly disable GPU inference with the `--n-gpu-layers|-ngl 0` command-line
2023-09-04 19:26:24 +00:00
argument.
2023-06-04 20:34:30 +00:00
2023-07-10 15:49:56 +00:00
### MPI Build
MPI lets you distribute the computation over a cluster of machines. Because of the serial nature of LLM prediction, this won't yield any end-to-end speed-ups, but it will let you run larger models than would otherwise fit into RAM on a single machine.
First you will need MPI libraries installed on your system. The two most popular (only?) options are [MPICH ](https://www.mpich.org ) and [OpenMPI ](https://www.open-mpi.org ). Either can be installed with a package manager (`apt`, Homebrew, MacPorts, etc).
Next you will need to build the project with `LLAMA_MPI` set to true on all machines; if you're building with `make` , you will also need to specify an MPI-capable compiler (when building with CMake, this is configured automatically):
- Using `make` :
```bash
make CC=mpicc CXX=mpicxx LLAMA_MPI=1
```
- Using `CMake` :
```bash
cmake -S . -B build -DLLAMA_MPI=ON
```
Once the programs are built, download/convert the weights on all of the machines in your cluster. The paths to the weights and programs should be identical on all machines.
Next, ensure password-less SSH access to each machine from the primary host, and create a `hostfile` with a list of the hostnames and their relative "weights" (slots). If you want to use localhost for computation, use its local subnet IP address rather than the loopback address or "localhost".
Here is an example hostfile:
```
192.168.0.1:2
malvolio.local:1
```
The above will distribute the computation across 2 processes on the first host and 1 process on the second host. Each process will use roughly an equal amount of RAM. Try to keep these numbers small, as inter-process (intra-host) communication is expensive.
Finally, you're ready to run a computation using `mpirun` :
```bash
2023-08-21 20:07:43 +00:00
mpirun -hostfile hostfile -n 3 ./main -m ./models/7B/ggml-model-q4_0.gguf -n 128
2023-07-10 15:49:56 +00:00
```
2023-04-26 20:03:03 +00:00
### BLAS Build
2023-11-30 21:49:21 +00:00
Building the program with BLAS support may lead to some performance improvements in prompt processing using batch sizes higher than 32 (the default is 512). Support with CPU-only BLAS implementations doesn't affect the normal generation performance. We may see generation performance improvements with GPU-involved BLAS implementations, e.g. cuBLAS, hipBLAS and CLBlast. There are currently several different BLAS implementations available for build and use:
2023-04-26 20:03:03 +00:00
2023-06-05 20:32:36 +00:00
- #### Accelerate Framework:
2023-04-26 20:03:03 +00:00
This is only available on Mac PCs and it's enabled by default. You can just build using the normal instructions.
2023-06-05 20:32:36 +00:00
- #### OpenBLAS:
2023-04-26 20:03:03 +00:00
This provides BLAS acceleration using only the CPU. Make sure to have OpenBLAS installed on your machine.
- Using `make` :
- On Linux:
```bash
make LLAMA_OPENBLAS=1
```
- On Windows:
1. Download the latest fortran version of [w64devkit ](https://github.com/skeeto/w64devkit/releases ).
2. Download the latest version of [OpenBLAS for Windows ](https://github.com/xianyi/OpenBLAS/releases ).
3. Extract `w64devkit` on your pc.
4. From the OpenBLAS zip that you just downloaded copy `libopenblas.a` , located inside the `lib` folder, inside `w64devkit\x86_64-w64-mingw32\lib` .
5. From the same OpenBLAS zip copy the content of the `include` folder inside `w64devkit\x86_64-w64-mingw32\include` .
6. Run `w64devkit.exe` .
7. Use the `cd` command to reach the `llama.cpp` folder.
8. From here you can run:
```bash
make LLAMA_OPENBLAS=1
```
- Using `CMake` on Linux:
```bash
mkdir build
cd build
2023-05-20 14:58:31 +00:00
cmake .. -DLLAMA_BLAS=ON -DLLAMA_BLAS_VENDOR=OpenBLAS
2023-04-26 20:03:03 +00:00
cmake --build . --config Release
```
2023-06-05 20:32:36 +00:00
- #### BLIS
2023-05-20 14:58:31 +00:00
2023-06-10 14:08:11 +00:00
Check [BLIS.md ](docs/BLIS.md ) for more information.
2023-05-20 14:58:31 +00:00
2024-02-02 07:56:31 +00:00
- #### SYCL
SYCL is a higher-level programming model to improve programming productivity on various hardware accelerators.
llama.cpp based on SYCL is used to **support Intel GPU** (Data Center Max series, Flex series, Arc series, Built-in GPU and iGPU).
For detailed info, please refer to [llama.cpp for SYCL ](README-sycl.md ).
2023-12-30 08:07:48 +00:00
- #### Intel oneMKL
2024-02-02 07:56:31 +00:00
Building through oneAPI compilers will make avx_vnni instruction set available for intel processors that do not support avx512 and avx512_vnni. Please note that this build config **does not support Intel GPU** . For Intel GPU support, please refer to [llama.cpp for SYCL ](./README-sycl.md ).
2023-12-30 08:07:48 +00:00
- Using manual oneAPI installation:
By default, `LLAMA_BLAS_VENDOR` is set to `Generic` , so if you already sourced intel environment script and assign `-DLLAMA_BLAS=ON` in cmake, the mkl version of Blas will automatically been selected. Otherwise please install oneAPI and follow the below steps:
```bash
mkdir build
cd build
2024-02-02 07:56:31 +00:00
source /opt/intel/oneapi/setvars.sh # You can skip this step if in oneapi-basekit docker image, only required for manual installation
2023-12-30 08:07:48 +00:00
cmake .. -DLLAMA_BLAS=ON -DLLAMA_BLAS_VENDOR=Intel10_64lp -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx -DLLAMA_NATIVE=ON
cmake --build . --config Release
```
2023-05-20 14:58:31 +00:00
2023-12-30 08:07:48 +00:00
- Using oneAPI docker image:
2024-02-02 07:56:31 +00:00
If you do not want to source the environment vars and install oneAPI manually, you can also build the code using intel docker container: [oneAPI-basekit ](https://hub.docker.com/r/intel/oneapi-basekit ). Then, you can use the commands given above.
2023-12-30 08:07:48 +00:00
Check [Optimizing and Running LLaMA2 on Intel® CPU ](https://www.intel.com/content/www/us/en/content-details/791610/optimizing-and-running-llama2-on-intel-cpu.html ) for more information.
2023-05-20 14:58:31 +00:00
2023-06-05 20:32:36 +00:00
- #### cuBLAS
2023-04-26 20:03:03 +00:00
2023-10-06 19:13:36 +00:00
This provides BLAS acceleration using the CUDA cores of your Nvidia GPU. Make sure to have the CUDA toolkit installed. You can download it from your Linux distro's package manager (e.g. `apt install nvidia-cuda-toolkit` ) or from here: [CUDA Toolkit ](https://developer.nvidia.com/cuda-downloads ).
2023-12-22 15:11:12 +00:00
For Jetson user, if you have Jetson Orin, you can try this: [Offical Support ](https://www.jetson-ai-lab.com/tutorial_text-generation.html ). If you are using an old model(nano/TX2), need some additional operations before compiling.
2023-04-26 20:03:03 +00:00
- Using `make` :
```bash
make LLAMA_CUBLAS=1
```
- Using `CMake` :
```bash
mkdir build
cd build
cmake .. -DLLAMA_CUBLAS=ON
cmake --build . --config Release
```
2023-06-19 08:23:56 +00:00
The environment variable [`CUDA_VISIBLE_DEVICES` ](https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#env-vars ) can be used to specify which GPU(s) will be used. The following compilation options are also available to tweak performance:
2023-07-31 13:44:35 +00:00
<!-- -
| LLAMA_CUDA_CUBLAS | Boolean | false | Use cuBLAS instead of custom CUDA kernels for prompt processing. Faster for all quantization formats except for q4_0 and q8_0, especially for k-quants. Increases VRAM usage (700 MiB for 7b, 970 MiB for 13b, 1430 MiB for 33b). |
--->
2023-09-17 14:37:53 +00:00
| Option | Legal values | Default | Description |
|--------------------------------|------------------------|---------|-------------|
| LLAMA_CUDA_FORCE_DMMV | Boolean | false | Force the use of dequantization + matrix vector multiplication kernels instead of using kernels that do matrix vector multiplication on quantized data. By default the decision is made based on compute capability (MMVQ for 6.1/Pascal/GTX 1000 or higher). Does not affect k-quants. |
| LLAMA_CUDA_DMMV_X | Positive integer >= 32 | 32 | Number of values in x direction processed by the CUDA dequantization + matrix vector multiplication kernel per iteration. Increasing this value can improve performance on fast GPUs. Power of 2 heavily recommended. Does not affect k-quants. |
| LLAMA_CUDA_MMV_Y | Positive integer | 1 | Block size in y direction for the CUDA mul mat vec kernels. Increasing this value can improve performance on fast GPUs. Power of 2 recommended. |
| LLAMA_CUDA_F16 | Boolean | false | If enabled, use half-precision floating point arithmetic for the CUDA dequantization + mul mat vec kernels and for the q4_1 and q5_1 matrix matrix multiplication kernels. Can improve performance on relatively recent GPUs. |
| LLAMA_CUDA_KQUANTS_ITER | 1 or 2 | 2 | Number of values processed per iteration and per CUDA thread for Q2_K and Q6_K quantization formats. Setting this value to 1 can improve performance for slow GPUs. |
| LLAMA_CUDA_PEER_MAX_BATCH_SIZE | Positive integer | 128 | Maximum batch size for which to enable peer access between multiple GPUs. Peer access requires either Linux or NVLink. When using NVLink enabling peer access for larger batch sizes is potentially beneficial. |
2023-06-03 13:35:20 +00:00
2023-08-25 09:09:42 +00:00
- #### hipBLAS
2023-09-08 16:04:32 +00:00
This provides BLAS acceleration on HIP-supported AMD GPUs.
2023-08-25 09:09:42 +00:00
Make sure to have ROCm installed.
You can download it from your Linux distro's package manager or from here: [ROCm Quick Start (Linux) ](https://rocm.docs.amd.com/en/latest/deploy/linux/quick_start.html ).
- Using `make` :
```bash
make LLAMA_HIPBLAS=1
```
2023-12-21 19:45:32 +00:00
- Using `CMake` for Linux (assuming a gfx1030-compatible AMD GPU):
2023-08-25 09:09:42 +00:00
```bash
2023-12-21 19:45:32 +00:00
CC=/opt/rocm/llvm/bin/clang CXX=/opt/rocm/llvm/bin/clang++ \
cmake -H. -Bbuild -DLLAMA_HIPBLAS=ON -DAMDGPU_TARGETS=gfx1030 -DCMAKE_BUILD_TYPE=Release \
& & cmake --build build -- -j 16
2023-08-25 09:09:42 +00:00
```
2023-12-21 19:45:32 +00:00
On Linux it is also possible to use unified memory architecture (UMA) to share main memory between the CPU and integrated GPU by setting `-DLLAMA_HIP_UMA=ON"` .
2023-12-22 08:03:25 +00:00
However, this hurts performance for non-integrated GPUs (but enables working with integrated GPUs).
- Using `make` (example for target gfx1030, build with 16 CPU threads):
```bash
make -j16 LLAMA_HIPBLAS=1 LLAMA_HIP_UMA=1 AMDGPU_TARGETS=gxf1030
```
2023-12-21 19:45:32 +00:00
- Using `CMake` for Windows (using x64 Native Tools Command Prompt for VS, and assuming a gfx1100-compatible AMD GPU):
2023-11-20 15:02:46 +00:00
```bash
2023-11-24 07:52:39 +00:00
set PATH=%HIP_PATH%\bin;%PATH%
2023-11-20 15:02:46 +00:00
mkdir build
cd build
cmake -G Ninja -DAMDGPU_TARGETS=gfx1100 -DLLAMA_HIPBLAS=ON -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ..
cmake --build .
```
Make sure that `AMDGPU_TARGETS` is set to the GPU arch you want to compile for. The above example uses `gfx1100` that corresponds to Radeon RX 7900XTX/XT/GRE. You can find a list of targets [here ](https://llvm.org/docs/AMDGPUUsage.html#processors )
2023-12-21 19:45:32 +00:00
Find your gpu version string by matching the most significant version information from `rocminfo | grep gfx | head -1 | awk '{print $2}'` with the list of processors, e.g. `gfx1035` maps to `gfx1030` .
2023-11-20 15:02:46 +00:00
2023-08-25 09:09:42 +00:00
The environment variable [`HIP_VISIBLE_DEVICES` ](https://rocm.docs.amd.com/en/latest/understand/gpu_isolation.html#hip-visible-devices ) can be used to specify which GPU(s) will be used.
2023-12-21 19:45:32 +00:00
If your GPU is not officially supported you can use the environment variable [`HSA_OVERRIDE_GFX_VERSION`] set to a similar GPU, for example 10.3.0 on RDNA2 (e.g. gfx1030, gfx1031, or gfx1035) or 11.0.0 on RDNA3.
2023-08-25 09:09:42 +00:00
The following compilation options are also available to tweak performance (yes, they refer to CUDA, not HIP, because it uses the same code as the cuBLAS version above):
| Option | Legal values | Default | Description |
|-------------------------|------------------------|---------|-------------|
| LLAMA_CUDA_DMMV_X | Positive integer >= 32 | 32 | Number of values in x direction processed by the HIP dequantization + matrix vector multiplication kernel per iteration. Increasing this value can improve performance on fast GPUs. Power of 2 heavily recommended. Does not affect k-quants. |
| LLAMA_CUDA_MMV_Y | Positive integer | 1 | Block size in y direction for the HIP mul mat vec kernels. Increasing this value can improve performance on fast GPUs. Power of 2 recommended. Does not affect k-quants. |
| LLAMA_CUDA_KQUANTS_ITER | 1 or 2 | 2 | Number of values processed per iteration and per HIP thread for Q2_K and Q6_K quantization formats. Setting this value to 1 can improve performance for slow GPUs. |
2023-06-05 20:32:36 +00:00
- #### CLBlast
2023-05-27 15:47:55 +00:00
OpenCL acceleration is provided by the matrix multiplication kernels from the [CLBlast ](https://github.com/CNugteren/CLBlast ) project and custom kernels for ggml that can generate tokens on the GPU.
You will need the [OpenCL SDK ](https://github.com/KhronosGroup/OpenCL-SDK ).
- For Ubuntu or Debian, the packages `opencl-headers` , `ocl-icd` may be needed.
2023-09-02 12:53:18 +00:00
- For Windows, a pre-built SDK is available on the [OpenCL Releases ](https://github.com/KhronosGroup/OpenCL-SDK/releases ) page.

##### Running Llama with CLBlast
2023-05-27 15:47:55 +00:00
2023-06-04 20:34:30 +00:00
The CLBlast build supports `--gpu-layers|-ngl` like the CUDA version does.
2023-05-27 15:47:55 +00:00
To select the correct platform (driver) and device (GPU), you can use the environment variables `GGML_OPENCL_PLATFORM` and `GGML_OPENCL_DEVICE` .
The selection can be a number (starting from 0) or a text string to search:
```sh
GGML_OPENCL_PLATFORM=1 ./main ...
GGML_OPENCL_DEVICE=2 ./main ...
GGML_OPENCL_PLATFORM=Intel ./main ...
GGML_OPENCL_PLATFORM=AMD GGML_OPENCL_DEVICE=1 ./main ...
```
The default behavior is to find the first GPU device, but when it is an integrated GPU on a laptop, for instance, the selectors are useful.
Using the variables it is possible to select a CPU-based driver as well, if so desired.
You can get a list of platforms and devices from the `clinfo -l` command, etc.

For example, on Ubuntu 22.04 (jammy), use the command below:
```bash
wget -qO - https://packages.lunarg.com/lunarg-signing-key-pub.asc | apt-key add -
wget -qO /etc/apt/sources.list.d/lunarg-vulkan-jammy.list https://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list
apt update -y
apt-get install -y vulkan-sdk
# To verify the installation, use the command below:
vulkaninfo
```
2024-02-07 06:21:30 +00:00
Alternatively your package manager might be able to provide the appropiate libraries. For example for Ubuntu 22.04 you can install `libvulkan-dev` instead.
2024-02-02 07:56:31 +00:00
Then, build llama.cpp using the cmake command below:
```bash
mkdir -p build
cd build
cmake .. -DLLAMA_VULKAN=1
cmake --build . --config Release
# Test the output binary (with "-ngl 33" to offload all layers to GPU)
./bin/main -m "PATH_TO_MODEL" -p "Hi you how are you" -n 50 -e -ngl 33 -t 4
# You should see in the output, ggml_vulkan detected your GPU. For example:

### Prepare and Quantize
To obtain the official LLaMA 2 weights please see the < a href = "#obtaining-and-using-the-facebook-llama-2-model" > Obtaining and using the Facebook LLaMA 2 model</ a > section. There is also a large selection of pre-quantized `gguf` models available on Hugging Face.

# install Python dependencies
py : new conversion script (#545)
Current status: Working, except for the latest GPTQ-for-LLaMa format
that includes `g_idx`. This turns out to require changes to GGML, so
for now it only works if you use the `--outtype` option to dequantize it
back to f16 (which is pointless except for debugging).
I also included some cleanup for the C++ code.
This script is meant to replace all the existing conversion scripts
(including the ones that convert from older GGML formats), while also
adding support for some new formats. Specifically, I've tested with:
- [x] `LLaMA` (original)
- [x] `llama-65b-4bit`
- [x] `alpaca-native`
- [x] `alpaca-native-4bit`
- [x] LLaMA converted to 'transformers' format using
`convert_llama_weights_to_hf.py`
- [x] `alpaca-native` quantized with `--true-sequential --act-order
--groupsize 128` (dequantized only)
- [x] same as above plus `--save_safetensors`
- [x] GPT4All
- [x] stock unversioned ggml
- [x] ggmh
There's enough overlap in the logic needed to handle these different
cases that it seemed best to move to a single script.
I haven't tried this with Alpaca-LoRA because I don't know where to find
it.
Useful features:
- Uses multiple threads for a speedup in some cases (though the Python
GIL limits the gain, and sometimes it's disk-bound anyway).
- Combines split models into a single file (both the intra-tensor split
of the original and the inter-tensor split of 'transformers' format
files). Single files are more convenient to work with and more
friendly to future changes to use memory mapping on the C++ side. To
accomplish this without increasing memory requirements, it has some
custom loading code which avoids loading whole input files into memory
at once.
- Because of the custom loading code, it no longer depends in PyTorch,
which might make installing dependencies slightly easier or faster...
although it still depends on NumPy and sentencepiece, so I don't know
if there's any meaningful difference. In any case, I also added a
requirements.txt file to lock the dependency versions in case of any
future breaking changes.
- Type annotations checked with mypy.
- Some attempts to be extra user-friendly:
- The script tries to be forgiving with arguments, e.g. you can
specify either the model file itself or the directory containing
it.
- The script doesn't depend on config.json / params.json, just in
case the user downloaded files individually and doesn't have those
handy. But you still need tokenizer.model and, for Alpaca,
added_tokens.json.
- The script tries to give a helpful error message if
added_tokens.json is missing.

### Run the quantized model
2023-09-21 19:00:24 +00:00
2024-02-07 06:21:30 +00:00
```bash
# start inference on a gguf model
./main -m ./models/mymodel/ggml-model-Q4_K_M.gguf -n 128
2023-03-10 19:47:46 +00:00
```
2023-03-11 08:47:09 +00:00
When running the larger models, make sure you have enough disk space to store all the intermediate files.
2023-10-17 18:13:21 +00:00
### Running on Windows with prebuilt binaries
You will find prebuilt Windows binaries on the release page.
Simply download and extract the latest zip package of choice: (e.g. `llama-b1380-bin-win-avx2-x64.zip` )
From the unzipped folder, open a terminal/cmd window here and place a pre-converted `.gguf` model file. Test out the main example like so:
```
.\main -m llama-2-7b.Q4_0.gguf -n 128
```
2023-03-18 20:58:46 +00:00
### Memory/Disk Requirements
2023-04-19 19:52:14 +00:00
As the models are currently fully loaded into memory, you will need adequate disk space to save them and sufficient RAM to load them. At the moment, memory and disk requirements are the same.

### Perplexity (measuring model quality)
You can use the `perplexity` example to measure perplexity over a given prompt (lower perplexity is better).
For more information, see [https://huggingface.co/docs/transformers/perplexity ](https://huggingface.co/docs/transformers/perplexity ).
The perplexity measurements in table above are done against the `wikitext2` test dataset (https://paperswithcode.com/dataset/wikitext-2), with context length of 512.
The time per token is measured on a MacBook M1 Pro 32GB RAM using 4 and 8 threads.
2023-10-06 19:13:36 +00:00
#### How to run
2024-02-18 20:39:30 +00:00
1. Download/extract: https://huggingface.co/datasets/ggml-org/ci/resolve/main/wikitext-2-raw-v1.zip
2023-10-06 19:13:36 +00:00
2. Run `./perplexity -m models/7B/ggml-model-q4_0.gguf -f wiki.test.raw`
3. Output:
```
perplexity : calculating perplexity over 655 chunks
24.43 seconds per pass - ETA 4.45 hours
[1]4.5970,[2]5.1807,[3]6.0382,...
```
And after 4.45 hours, you will have the final perplexity.
2023-03-12 21:13:28 +00:00
### Interactive mode
If you want a more ChatGPT-like experience, you can run in interactive mode by passing `-i` as a parameter.
2024-03-02 17:27:26 +00:00
In this mode, you can always interrupt generation by pressing Ctrl+C and entering one or more lines of text, which will be converted into tokens and appended to the current context. You can also specify a *reverse prompt* with the parameter `-r "reverse prompt string"` . This will result in user input being prompted whenever the exact tokens of the reverse prompt string are encountered in the generation. A typical use is to use a prompt that makes LLaMA emulate a chat between multiple users, say Alice and Bob, and pass `-r "Alice:"` .
2023-03-12 21:13:28 +00:00
2023-04-19 19:52:14 +00:00
Here is an example of a few-shot interaction, invoked with the command
2023-03-21 16:10:32 +00:00
```bash
2023-04-19 19:52:14 +00:00
# default arguments using a 7B model
2023-03-25 18:36:52 +00:00
./examples/chat.sh
2023-04-19 19:52:14 +00:00
# advanced chat with a 13B model
2023-03-25 18:36:52 +00:00
./examples/chat-13B.sh
2023-03-12 21:39:01 +00:00
2023-04-19 19:52:14 +00:00
# custom arguments using a 13B model
2023-08-21 20:07:43 +00:00
./main -m ./models/13B/ggml-model-q4_0.gguf -n 256 --repeat_penalty 1.0 --color -i -r "User:" -f prompts/chat-with-bob.txt
2023-03-12 21:13:28 +00:00
```
2023-03-21 16:10:32 +00:00
2023-04-24 15:45:32 +00:00
Note the use of `--color` to distinguish between user input and generated text. Other parameters are explained in more detail in the [README ](examples/main/README.md ) for the `main` example program.

2023-03-12 21:13:28 +00:00
2023-05-24 06:24:01 +00:00
### Persistent Interaction
The prompt, user inputs, and model generations can be saved and resumed across calls to `./main` by leveraging `--prompt-cache` and `--prompt-cache-all` . The `./examples/chat-persistent.sh` script demonstrates this with support for long-running, resumable chat sessions. To use this example, you must provide a file to cache the initial chat prompt and a directory to save the chat session, and may optionally provide the same variables as `chat-13B.sh` . The same prompt cache can be reused for new chat sessions. Note that both prompt cache and chat directory are tied to the initial prompt (`PROMPT_TEMPLATE`) and the model file.
```bash
# Start a new chat
PROMPT_CACHE_FILE=chat.prompt.bin CHAT_SAVE_DIR=./chat/default ./examples/chat-persistent.sh
# Resume that chat
PROMPT_CACHE_FILE=chat.prompt.bin CHAT_SAVE_DIR=./chat/default ./examples/chat-persistent.sh
# Start a different chat with the same prompt/model
PROMPT_CACHE_FILE=chat.prompt.bin CHAT_SAVE_DIR=./chat/another ./examples/chat-persistent.sh
# Different prompt cache for different prompt/model
PROMPT_TEMPLATE=./prompts/chat-with-bob.txt PROMPT_CACHE_FILE=bob.prompt.bin \
CHAT_SAVE_DIR=./chat/bob ./examples/chat-persistent.sh
```
2023-08-23 01:01:57 +00:00
### Constrained output with grammars
`llama.cpp` supports grammars to constrain model output. For example, you can force the model to output JSON only:
```bash
./main -m ./models/13B/ggml-model-q4_0.gguf -n 256 --grammar-file grammars/json.gbnf -p 'Request: schedule a call at 8pm; Command:'
```
The `grammars/` folder contains a handful of sample grammars. To write your own, check out the [GBNF Guide ](./grammars/README.md ).
2023-09-29 11:15:57 +00:00
For authoring more complex JSON grammars, you can also check out https://grammar.intrinsiclabs.ai/, a browser app that lets you write TypeScript interfaces which it compiles to GBNF grammars that you can save for local use. Note that the app is built and maintained by members of the community, please file any issues or FRs on [its repo ](http://github.com/intrinsiclabsai/gbnfgen ) and not this one.
2024-02-07 06:21:30 +00:00

#### Building the Project using Android NDK
2023-04-01 14:57:30 +00:00
You can easily run `llama.cpp` on Android device with [termux ](https://termux.dev/ ).
2023-06-18 08:28:26 +00:00
First, install the essential packages for termux:
```
pkg install clang wget git cmake
```
Second, obtain the [Android NDK ](https://developer.android.com/ndk ) and then build with CMake:
2023-03-14 13:30:08 +00:00
```
$ mkdir build-android

#### Building the Project using Termux (F-Droid)
Termux from F-Droid offers an alternative route to execute the project on an Android device. This method empowers you to construct the project right from within the terminal, negating the requirement for a rooted device or SD Card.
Outlined below are the directives for installing the project using OpenBLAS and CLBlast. This combination is specifically designed to deliver peak performance on recent devices that feature a GPU.
If you opt to utilize OpenBLAS, you'll need to install the corresponding package.
```
apt install libopenblas
```
Subsequently, if you decide to incorporate CLBlast, you'll first need to install the requisite OpenCL packages:
```
apt install ocl-icd opencl-headers opencl-clhpp clinfo
```
In order to compile CLBlast, you'll need to first clone the respective Git repository, which can be found at this URL: https://github.com/CNugteren/CLBlast. Alongside this, clone this repository into your home directory. Once this is done, navigate to the CLBlast folder and execute the commands detailed below:
```
cmake .
make
cp libclblast.so* $PREFIX/lib
cp ./include/clblast.h ../llama.cpp
```
Following the previous steps, navigate to the LlamaCpp directory. To compile it with OpenBLAS and CLBlast, execute the command provided below:
```
cp /data/data/com.termux/files/usr/include/openblas/cblas.h .
cp /data/data/com.termux/files/usr/include/openblas/openblas_config.h .
make LLAMA_CLBLAST=1 //(sometimes you need to run this command twice)
```
Upon completion of the aforementioned steps, you will have successfully compiled the project. To run it using CLBlast, a slight adjustment is required: a command must be issued to direct the operations towards your device's physical GPU, rather than the virtual one. The necessary command is detailed below:
```
GGML_OPENCL_PLATFORM=0
GGML_OPENCL_DEVICE=0
2023-06-24 10:32:13 +00:00
export LD_LIBRARY_PATH=/vendor/lib64:$LD_LIBRARY_PATH
2023-06-17 09:01:06 +00:00
```
2023-06-26 19:34:45 +00:00
(Note: some Android devices, like the Zenfone 8, need the following command instead - "export LD_LIBRARY_PATH=/system/vendor/lib64:$LD_LIBRARY_PATH". Source: https://www.reddit.com/r/termux/comments/kc3ynp/opencl_working_in_termux_more_in_comments/ )
2023-06-17 09:01:06 +00:00
For easy and swift re-execution, consider documenting this final part in a .sh script file. This will enable you to rerun the process with minimal hassle.
2023-07-09 08:20:43 +00:00
Place your desired model into the `~/llama.cpp/models/` directory and execute the `./main (...)` script.

### Docker
#### Prerequisites
* Docker must be installed and running on your system.
2023-04-19 19:52:14 +00:00
* Create a folder to store big models & intermediate files (ex. /llama/models)
2023-03-17 09:47:06 +00:00
#### Images
2024-01-28 07:55:31 +00:00
We have three Docker images available for this project:
2023-03-17 09:47:06 +00:00
2023-09-14 16:47:00 +00:00
1. `ghcr.io/ggerganov/llama.cpp:full` : This image includes both the main executable file and the tools to convert LLaMA models into ggml and convert into 4-bit quantization. (platforms: `linux/amd64` , `linux/arm64` )
2. `ghcr.io/ggerganov/llama.cpp:light` : This image only includes the main executable file. (platforms: `linux/amd64` , `linux/arm64` )
2024-02-14 15:15:49 +00:00
3. `ghcr.io/ggerganov/llama.cpp:server` : This image only includes the server executable file. (platforms: `linux/amd64` , `linux/arm64` )
2023-09-14 16:47:00 +00:00
Additionally, there the following images, similar to the above:
- `ghcr.io/ggerganov/llama.cpp:full-cuda` : Same as `full` but compiled with CUDA support. (platforms: `linux/amd64` )
- `ghcr.io/ggerganov/llama.cpp:light-cuda` : Same as `light` but compiled with CUDA support. (platforms: `linux/amd64` )
2024-01-28 07:55:31 +00:00
- `ghcr.io/ggerganov/llama.cpp:server-cuda` : Same as `server` but compiled with CUDA support. (platforms: `linux/amd64` )
2023-09-14 16:47:00 +00:00
- `ghcr.io/ggerganov/llama.cpp:full-rocm` : Same as `full` but compiled with ROCm support. (platforms: `linux/amd64` , `linux/arm64` )
- `ghcr.io/ggerganov/llama.cpp:light-rocm` : Same as `light` but compiled with ROCm support. (platforms: `linux/amd64` , `linux/arm64` )
2024-01-28 07:55:31 +00:00
- `ghcr.io/ggerganov/llama.cpp:server-rocm` : Same as `server` but compiled with ROCm support. (platforms: `linux/amd64` , `linux/arm64` )
2023-09-14 16:47:00 +00:00
2023-11-30 21:43:32 +00:00
The GPU enabled images are not currently tested by CI beyond being built. They are not built with any variation from the ones in the Dockerfiles defined in [.devops/ ](.devops/ ) and the GitHub Action defined in [.github/workflows/docker.yml ](.github/workflows/docker.yml ). If you need different settings (for example, a different CUDA or ROCm library, you'll need to build the images locally for now).
2023-03-17 09:47:06 +00:00
#### Usage
The easiest way to download the models, convert them to ggml and optimize them is with the --all-in-one command which includes the full docker image.
2023-04-06 06:56:58 +00:00
Replace `/path/to/models` below with the actual path where you downloaded the models.
2023-04-19 19:52:14 +00:00
```bash
2023-04-06 06:56:58 +00:00
docker run -v /path/to/models:/models ghcr.io/ggerganov/llama.cpp:full --all-in-one "/models/" 7B
2023-03-17 09:47:06 +00:00
```
2023-04-19 19:52:14 +00:00
On completion, you are ready to play!
2023-03-17 09:47:06 +00:00
```bash
2023-08-21 20:07:43 +00:00
docker run -v /path/to/models:/models ghcr.io/ggerganov/llama.cpp:full --run -m /models/7B/ggml-model-q4_0.gguf -p "Building a website can be done in 10 simple steps:" -n 512
2023-03-17 09:47:06 +00:00
```
2023-04-19 19:52:14 +00:00
or with a light image:
2023-03-17 09:47:06 +00:00
```bash
2023-08-21 20:07:43 +00:00
docker run -v /path/to/models:/models ghcr.io/ggerganov/llama.cpp:light -m /models/7B/ggml-model-q4_0.gguf -p "Building a website can be done in 10 simple steps:" -n 512
2023-03-17 09:47:06 +00:00
```
2023-03-14 13:30:08 +00:00
2024-01-28 07:55:31 +00:00
or with a server image:
```bash
docker run -v /path/to/models:/models -p 8000:8000 ghcr.io/ggerganov/llama.cpp:server -m /models/7B/ggml-model-q4_0.gguf --port 8000 --host 0.0.0.0 -n 512
```
2023-07-07 18:25:25 +00:00
### Docker With CUDA
Assuming one has the [nvidia-container-toolkit ](https://github.com/NVIDIA/nvidia-container-toolkit ) properly installed on Linux, or is using a GPU enabled cloud, `cuBLAS` should be accessible inside the container.
#### Building Locally
```bash
docker build -t local/llama.cpp:full-cuda -f .devops/full-cuda.Dockerfile .
docker build -t local/llama.cpp:light-cuda -f .devops/main-cuda.Dockerfile .
2024-01-28 07:55:31 +00:00
docker build -t local/llama.cpp:server-cuda -f .devops/server-cuda.Dockerfile .
2023-07-07 18:25:25 +00:00
```
You may want to pass in some different `ARGS` , depending on the CUDA environment supported by your container host, as well as the GPU architecture.
The defaults are:
- `CUDA_VERSION` set to `11.7.1`
- `CUDA_DOCKER_ARCH` set to `all`
The resulting images, are essentially the same as the non-CUDA images:
1. `local/llama.cpp:full-cuda` : This image includes both the main executable file and the tools to convert LLaMA models into ggml and convert into 4-bit quantization.
2. `local/llama.cpp:light-cuda` : This image only includes the main executable file.
2024-01-28 07:55:31 +00:00
3. `local/llama.cpp:server-cuda` : This image only includes the server executable file.
2023-07-07 18:25:25 +00:00
#### Usage
After building locally, Usage is similar to the non-CUDA examples, but you'll need to add the `--gpus` flag. You will also want to use the `--n-gpu-layers` flag.
```bash
2023-08-21 20:07:43 +00:00
docker run --gpus all -v /path/to/models:/models local/llama.cpp:full-cuda --run -m /models/7B/ggml-model-q4_0.gguf -p "Building a website can be done in 10 simple steps:" -n 512 --n-gpu-layers 1
docker run --gpus all -v /path/to/models:/models local/llama.cpp:light-cuda -m /models/7B/ggml-model-q4_0.gguf -p "Building a website can be done in 10 simple steps:" -n 512 --n-gpu-layers 1
2024-01-28 07:55:31 +00:00
docker run --gpus all -v /path/to/models:/models local/llama.cpp:server-cuda -m /models/7B/ggml-model-q4_0.gguf --port 8000 --host 0.0.0.0 -n 512 --n-gpu-layers 1
2023-07-07 18:25:25 +00:00
```

### Coding guidelines
2023-03-13 07:42:26 +00:00
- Avoid adding third-party dependencies, extra files, extra headers, etc.
- Always consider cross-compatibility with other operating systems and architectures
2023-03-14 07:43:52 +00:00
- Avoid fancy looking modern STL constructs, use basic `for` loops, avoid templates, keep it simple
2023-03-13 07:42:26 +00:00
- There are no strict rules for the code style, but try to follow the patterns in the code (indentation, spaces, etc.). Vertical alignment makes things more readable and easier to batch edit
2023-04-19 19:52:14 +00:00
- Clean-up any trailing whitespaces, use 4 spaces for indentation, brackets on the same line, `void * ptr` , `int & a`
2023-03-14 07:43:52 +00:00
- See [good first issues ](https://github.com/ggerganov/llama.cpp/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22 ) for tasks suitable for first contributions
2023-12-21 17:27:14 +00:00
- Tensors store data in row-major order. We refer to dimension 0 as columns, 1 as rows, 2 as matrices
- Matrix multiplication is unconventional: [`z = ggml_mul_mat(ctx, x, y)` ](https://github.com/ggerganov/llama.cpp/blob/880e352277fc017df4d5794f0c21c44e1eae2b84/ggml.h#L1058-L1064 ) means `zT = x @ yT`
