What is llama.cpp?

llama.cpp is a C and C++ tool that lets you run large language models directly on your own computer, without needing to send your data to a cloud service. It focuses on making LLM inference, the step where a trained model generates text, fast and practical on ordinary hardware, from laptops to servers, rather than just specialized GPU clusters. You can install it a few different ways: through package managers like brew, nix, winget, or conda-forge, by running it in Docker, by downloading pre-built binaries from the releases page, or by building it yourself from the source code. Once installed, you point it at a model file in the GGUF format, either one stored locally or one pulled directly from Hugging Face, and start generating text from the command line or through a built-in web server that speaks the same API style as OpenAI's. Under the hood, the project is written in plain C and C++ with no external dependencies, and it is tuned to take advantage of the specific hardware it runs on: Apple Silicon chips, AVX and AVX512 instructions on Intel and AMD processors, RISC-V extensions, and GPU acceleration through CUDA, Vulkan, SYCL, HIP, or MUSA depending on your graphics card. It also supports quantization, a technique that shrinks a model down to use less memory, from 1.5-bit up to 8-bit precision, so it can run on machines that would not otherwise have enough RAM or VRAM. The project supports a wide range of open model families, including LLaMA, Mistral, Mixtral, Falcon, Gemma, Qwen, and DeepSeek, with new models added regularly. It also serves as the base for companion tools like editor plugins for VS Code, Vim, and Neovim that use it for code completion. This particular repository is a personal fork of the original ggml-org/llama.cpp project, tracking the upstream codebase rather than introducing its own separate feature set.
