+# koboldcpp
+
+A self contained distributable from Concedo that exposes llama.cpp function bindings, allowing it to be used via a simulated Kobold API endpoint.
+
+What does it mean? You get llama.cpp with a fancy UI, persistent stories, editing tools, save formats, memory, world info, author's note, characters, scenarios and everything Kobold and Kobold Lite have to offer. In a tiny package around 20 MB in size, excluding model weights.
+
+![Preview](media/preview.png)
+
+## Usage
+- **[Download the latest .exe release here](https://github.com/LostRuins/koboldcpp/releases/latest)** or clone the git repo.
+- Windows binaries are provided in the form of **koboldcpp.exe**, which is a pyinstaller wrapper for a few **.dll** files and **koboldcpp.py**. If you feel concerned, you may prefer to rebuild it yourself with the provided makefiles and scripts.
+- Weights are not included, you can use the official llama.cpp `quantize.exe` to generate them from your official weight files (or download them from other places).
+- To run, execute **koboldcpp.exe** or drag and drop your quantized `ggml_model.bin` file onto the .exe, and then connect with Kobold or Kobold Lite. If you're not on windows, then run the script **KoboldCpp.py** after compiling the libraries.
+- By default, you can connect to http://localhost:5001
+- You can also run it using the command line `koboldcpp.exe [ggml_model.bin] [port]`. For info, please check `koboldcpp.exe --help`
+- Big context still too slow? Try the `--smartcontext` flag to reduce prompt processing frequency. Also, you can try to run with your GPU using CLBlast, with `--useclblast` flag for a speedup
+- Want even more speedup? Combine `--useclblast` with `--gpulayers` to offload entire layers to the GPU! **Much faster, but uses more VRAM**. Experiment to determine number of layers to offload.
+- If you are having crashes or issues, you can try turning off BLAS with the `--noblas` flag. You can also try running in a non-avx2 compatibility mode with `--noavx2`. Lastly, you can try turning off mmap with `--nommap`.
+
+For more information, be sure to run the program with the `--help` flag.
+
+## OSX and Linux
+- You will have to compile your binaries from source. A makefile is provided, simply run `make`
+- If you want you can also link your own install of OpenBLAS manually with `make LLAMA_OPENBLAS=1`
+- Alternatively, if you want you can also link your own install of CLBlast manually with `make LLAMA_CLBLAST=1`, for this you will need to obtain and link OpenCL and CLBlast libraries.
+  - For Arch Linux: Install `cblas` `openblas` and `clblast`.
+  - For Debian: Install `libclblast-dev` and `libopenblas-dev`.
+- For a full featured build, do `make LLAMA_OPENBLAS=1 LLAMA_CLBLAST=1 LLAMA_CUBLAS=1`
+- After all binaries are built, you can run the python script with the command `koboldcpp.py [ggml_model.bin] [port]`
+- Note: Many OSX users have found that the using Accelerate is actually faster than OpenBLAS. To try, you may wish to run with `--noblas` and compare speeds.
+
+## Compiling on Windows
+- You're encouraged to use the .exe released, but if you want to compile your binaries from source at Windows, the easiest way is:
+  - Use the latest release of w64devkit (https://github.com/skeeto/w64devkit). Be sure to use the "vanilla one", not i686 or other different stuff. If you try they will conflit with the precompiled libs!
+  - Make sure you are using the w64devkit integrated terminal, then run 'make' at the KoboldCpp source folder. This will create the .dll files.
+  - If you want to generate the .exe file, make sure you have the python module PyInstaller installed with pip ('pip install PyInstaller').
+  - Run the script make_pyinstaller.bat at a regular terminal (or Windows Explorer).
+  - The koboldcpp.exe file will be at your dist folder.
+- If you wish to use your own version of the additional Windows libraries (OpenCL, CLBlast and OpenBLAS), you can do it with:
+  - OpenCL - tested with https://github.com/KhronosGroup/OpenCL-SDK . If you wish to compile it, follow the repository instructions. You will need vcpkg.
+  - CLBlast - tested with https://github.com/CNugteren/CLBlast . If you wish to compile it you will need to reference the OpenCL files. It will only generate the ".lib" file if you compile using MSVC.
+  - OpenBLAS - tested with https://github.com/xianyi/OpenBLAS .
+  - Move the respectives .lib files to the /lib folder of your project, overwriting the older files.
+  - Also, replace the existing versions of the corresponding .dll files located in the project directory root (e.g. libopenblas.dll).
+  - Make the KoboldCPP project using the instructions above.
+
+## Android (Termux) Alternative method
+- See https://github.com/ggerganov/llama.cpp/pull/1828/files
+
+## CuBLAS?
+- You can attempt a CuBLAS build with `LLAMA_CUBLAS=1` or using the provided CMake file (best for visual studio users). If you use the CMake file to build, copy the `koboldcpp_cublas.dll` generated into the same directory as the `koboldcpp.py` file. If you are bundling executables, you may need to include CUDA dynamic libraries (such as `cublasLt64_11.dll` and `cublas64_11.dll`) in order for the executable to work correctly on a different PC. Note that support for CuBLAS is limited.
+
+## Considerations
+- For Windows: No installation, single file executable, (It Just Works)
+- Since v1.0.6, requires libopenblas, the prebuilt windows binaries are included in this repo. If not found, it will fall back to a mode without BLAS.
+- Since v1.15, requires CLBlast if enabled, the prebuilt windows binaries are included in this repo. If not found, it will fall back to a mode without CLBlast.
+- **I plan to keep backwards compatibility with ALL past llama.cpp AND alpaca.cpp models**. But you are also encouraged to reconvert/update your models if possible for best results.
+
+## License
+- The original GGML library and llama.cpp by ggerganov are licensed under the MIT License
+- However, Kobold Lite is licensed under the AGPL v3.0 License
+- The other files are also under the AGPL v3.0 License unless otherwise stated
+
+## Notes
+- Generation delay scales linearly with original prompt length. If OpenBLAS is enabled then prompt ingestion becomes about 2-3x faster. This is automatic on windows, but will require linking on OSX and Linux. CLBlast speeds this up even further, and `--gpulayers` + `--useclblast` more so.
+- I have heard of someone claiming a false AV positive report. The exe is a simple pyinstaller bundle that includes the necessary python scripts and dlls to run. If this still concerns you, you might wish to rebuild everything from source code using the makefile, and you can rebuild the exe yourself with pyinstaller by using `make_pyinstaller.bat`
+- Supported GGML models:
+  - LLAMA (All versions including ggml, ggmf, ggjt v1,v2,v3, openllama, gpt4all). Supports CLBlast and OpenBLAS acceleration for all versions.
+  - GPT-2 (All versions, including legacy f16, newer format + quanitzed, cerebras, starcoder) Supports CLBlast and OpenBLAS acceleration for newer formats, no GPU layer offload.
+  - GPT-J (All versions including legacy f16, newer format + quantized, pyg.cpp, new pygmalion, janeway etc.) Supports CLBlast and OpenBLAS acceleration for newer formats, no GPU layer offload.
+  - RWKV (all formats except Q4_1_O).
+  - GPT-NeoX / Pythia / StableLM / Dolly / RedPajama
+  - MPT models (ggjt v3)
+  - Basically every single current and historical GGML format that has ever existed should be supported, except for bloomz.cpp due to lack of demand.

 ### RNG Seed
 
--   `-s SEED, --seed SEED`: Set the random number generator (RNG) seed (default: -1, < 0 = random seed).
+-   `-s SEED, --seed SEED`: Set the random number generator (RNG) seed (default: -1, -1 = random seed).
 
 The RNG seed is used to initialize the random number generator that influences the text generation process. By setting a specific seed value, you can obtain consistent and reproducible results across multiple runs with the same input and settings. This can be helpful for testing, debugging, or comparing the effects of different options on the generated text to see when they diverge. If the seed is set to a value less than 0, a random seed will be used, which will result in different outputs on each run.
 
@@ -262,6 +262,10 @@ These options help improve the performance and memory usage of the LLaMA models.
 
 -   `--no-mmap`: Do not memory-map the model. By default, models are mapped into memory, which allows the system to load only the necessary parts of the model as needed. However, if the model is larger than your total amount of RAM or if your system is low on available memory, using mmap might increase the risk of pageouts, negatively impacting performance. Disabling mmap results in slower load times but may reduce pageouts if you're not using `--mlock`. Note that if the model is larger than the total amount of RAM, turning off mmap would prevent the model from loading at all.
 
+### NUMA support
+
+-   `--numa`: Attempt optimizations that help on some systems with non-uniform memory access. This currently consists of pinning an equal proportion of the threads to the cores on each NUMA node, and disabling prefetch and readahead for mmap. The latter causes mapped pages to be faulted in on first access instead of all at once, and in combination with pinning threads to NUMA nodes, more of the pages end up on the NUMA node where they are used. Note that if the model is already in the system page cache, for example because of a previous run without this option, this will have little effect unless you drop the page cache first. This can be done by rebooting the system or on Linux by writing '3' to '/proc/sys/vm/drop\_caches' as root.
+
 ### Memory Float 32
 
 -   `--memory-f32`: Use 32-bit floats instead of 16-bit floats for memory key+value. This doubles the context memory requirement and cached prompt file size but does not appear to increase generation quality in a measurable way. Not recommended.
