摘要

llama.cpp 是一个开源的 LLM 推理引擎，使用 C/C++ 编写，依赖极少，支持多种硬件和量化方法。此拉取请求限制了 llama_context 的最大输出数。

# 概述 延续 [#23764](https://github.com/ggml-org/llama.cpp/pull/23764)，此 PR 仅在可能时为 `n_seqs` 保留 logits 空间。使用 `-ub 2048` 和 MTP，**这为我节省了另外 1.2GB 的显存**。我还测试了 `llama-perplexity`，似乎运行正常。但也许有更好的 API，目前先作为草稿提交。在我看来，在 llama-context 中提供一个 API 是解决此问题的一个好方法，默认情况下它会保留所有 token，但在 server-context 中，我们可以尽可能将其设置为 1。 - u/am17an

快速开始

使用 llama.cpp 非常简单。以下是几种在您的机器上安装的方法：

  • 使用 brew、nix 或 winget 安装 llama.cpp
  • 使用 Docker 运行——请参阅我们的 Docker 文档
  • 从发布页面 (https://github.com/ggml-org/llama.cpp/releases) 下载预构建的二进制文件
  • 通过克隆此仓库从源码构建——请查看 我们的构建指南

安装完成后，您需要一个模型来使用。前往 获取和量化模型 部分了解更多。

示例命令：

# 使用本地模型文件
llama-cli -m my_model.gguf

# 或者直接从 Hugging Face 下载并运行模型
llama-cli -hf ggml-org/gemma-3-1b-it-GGUF

# 启动兼容 OpenAI 的 API 服务器
llama-server -hf ggml-org/gemma-3-1b-it-GGUF

描述

llama.cpp 的主要目标是在各种硬件（本地和云端）上以最小的设置和最先进的性能实现 LLM 推理。

  • 纯 C/C++ 实现，无任何依赖
  • Apple silicon 是头等公民——通过 ARM NEON、Accelerate 和 Metal 框架优化
  • x86 架构支持 AVX、AVX2、AVX512 和 AMX
  • RISC-V 架构支持 RVV、ZVFH、ZFH、ZICBOP 和 ZIHINTPAUSE
  • 1.5 位、2 位、3 位、4 位、5 位、6 位和 8 位整数量化，实现更快的推理和更少的内存使用
  • 自定义 CUDA 内核，用于在 NVIDIA GPU 上运行 LLM（通过 HIP 支持 AMD GPU，通过 MUSA 支持 Moore Threads GPU）
  • Vulkan 和 SYCL 后端支持
  • CPU+GPU 混合推理，可部分加速超过总 VRAM 容量的大模型

llama.cpp 项目是 ggml (https://github.com/ggml-org/ggml) 库开发新功能的主要试验场。
