Описание

llama.cpp — проект, который сделал локальный запуск больших моделей массовым. Чистый C/C++ без зависимостей, квантование весов, работа на CPU и GPU, конвертация моделей между форматами.

Что умеет:
— запускать модели на CPU с приемлемой скоростью;
— квантовать веса для экономии памяти;
— работать с Metal, CUDA и Vulkan;
— конвертировать модели из Safetensors в GGUF.

LLM inference in C/C++

ggml / ops / maintainer PRs / dev stats / lib llama API / llama-server REST API

Quick start

A few options to get llama.cpp installed on your machine:

# curl
curl -LsSf https://llama.app/install.sh | sh

# powershell
irm https://llama.app/install.ps1 | iex

Visit https://llama.app and follow the instructions
Run with Docker – see our Docker documentation
Download pre-built binaries from the releases page
Build from source by cloning this repository – check out our build guide

Once installed:

# Download and run a model directly from Hugging Face
llama cli -hf ggml-org/Qwen3.5-0.8B-GGUF

# Launch OpenAI-compatible API server
llama serve -hf ggml-org/Qwen3.5-0.8B-GGUF

VLM session with llama cli

Built-in web UI against llama serve

Description

The main goal of llama.cpp is to enable LLM (and VLM) 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 build on top of the ggml library.
