Here are several ways to install it on your machine: - Install `llama.cpp` using [brew, nix, winget, or conda-forge](docs/install.md) - Run with Docker - see our [Docker documentation](docs/docker.md) - Download pre-built binaries from the [releases page](https://github.com/ggml-org/llama.cpp/releases) - Build from source by cloning this repository - check out [our build guide](docs/build.md) Once installed, you'll need a model to work with. Head to the [Obtaining and quantizing models](#obtaining-and-quantizing-models) section to learn more. Example command: ```sh # Use a local model file llama-cli -m my_model.gguf # Or download and run a model directly from Hugging Face llama-cli -hf ggml-org/gemma-3-1b-it-GGUF # Launch OpenAI-compatible API server llama-server -hf ggml-org/gemma-3-1b-it-GGUF ``` ## Description The main goal of `llama.cpp` is to enable LLM inference with minimal setup and state-of-the-art performance on a wide range of hardware - locally and in the cloud. - Plain C/C++ implementation without any dependencies - Apple silicon is a first-class citizen - optimized via ARM NEON, Accelerate and Metal frameworks - AVX, AVX2, AVX512 and AMX support for x86 architectures - RVV, ZVFH, ZFH, ZICBOP and ZIHINTPAUSE support for RISC-V architectures - 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 - Custom CUDA kernels for running LLMs on NVIDIA GPUs (support for AMD GPUs via HIP and Moore Threads GPUs via MUSA) - Vulkan and SYCL backend support - CPU+GPU hybrid inference to partially accelerate models larger than the total VRAM capacity The `llama.cpp` project is the main playground for developing new features for the [ggml](https://github.com/ggml-org/ggml) library.
Models Typically finetunes of the base models below are supported as well.
