Quick start

Getting started with llama.cpp is straightforward. Here are several ways to install it on your machine:

Once installed, you'll need a model to work with. Head to the Obtaining and quantizing models section to learn more.

Example command:

# 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
  • 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 library.

Models Typically finetunes of the base models below are supported as well.

Obtaining and quantizing models

The Hugging Face platform hosts a number of LLMs compatible with llama.cpp:

You can either manually download the GGUF file or directly use any llama.cpp-compatible models from Hugging Face or other model hosting sites, such as ModelScope, by using this CLI argument: -hf <user>/<model>[:quant]. For example:

llama-cli -hf ggml-org/gemma-3-1b-it-GGUF

By default, the CLI would download from Hugging Face, you can switch to other options with the environment variable MODEL_ENDPOINT. For example, you may opt to downloading model checkpoints from ModelScope or other model sharing communities by setting the environment variable, e.g. MODEL_ENDPOINT=https://www.modelscope.cn/.

After downloading a model, use the CLI tools to run it locally - see below.

llama.cpp requires the model to be stored in the GGUF file format. Models in other data formats can be converted to GGUF using the convert_*.py Python scripts in this repo.

The Hugging Face platform provides a variety of online tools for converting, quantizing and hosting models with llama.cpp:

To learn more about model quantization, read this documentation

llama-cli

A CLI tool for accessing and experimenting with most of llama.cpp's functionality.

  • Run in conversation mode Models with a built-in chat template will automatically activate conversation mode. If this doesn't occur, you can manually enable it by adding `-cnv` and specifying a suitable chat template with `--chat-template NAME` ```bash llama-cli -m model.gguf # > hi, who are you? # Hi there! I'm your helpful assistant! I'm an AI-powered chatbot designed to assist and provide information to users like you. I'm here to help answer your questions, provide guidance, and offer support on a wide range of topics. I'm a friendly and knowledgeable AI, and I'm always happy to help with anything you need. What's on your mind, and how can I assist you today? # # > what is 1+1? # Easy peasy! The answer to 1+1 is... 2! ```
  • Run in conversation mode with custom chat template ```bash # use the "chatml" template (use -h to see the list of supported templates) llama-cli -m model.gguf -cnv --chat-template chatml # use a custom template llama-cli -m model.gguf -cnv --in-prefix 'User: ' --reverse-prompt 'User:' ```
  • Run simple text completion To disable conversation mode explicitly, use `-no-cnv` ```bash llama-cli -m model.gguf -p "I believe the meaning of life is" -n 128 -no-cnv # I believe the meaning of life is to find your own truth and to live in accordance with it. For me, this means being true to myself and following my passions, even if they don't align with societal expectations. I think that's what I love about yoga – it's not just a physical practice, but a spiritual one too. It's about connecting with yourself, listening to your inner voice, and honoring your own unique journey. ```
  • Constrain the output with a custom grammar ```bash llama-cli -m model.gguf -n 256 --grammar-file grammars/json.gbnf -p 'Request: schedule a call at 8pm; Command:' # {"appointmentTime": "8pm", "appointmentDetails": "schedule a a call"} ``` The [grammars/](grammars/) folder contains a handful of sample grammars. To write your own, check out the [GBNF Guide](grammars/README.md). For authoring more complex JSON grammars, check out https://grammar.intrinsiclabs.ai/

llama-server

A lightweight, OpenAI API compatible, HTTP server for serving LLMs.

  • Start a local HTTP server with default configuration on port 8080 ```bash llama-server -m model.gguf --port 8080 # Basic web UI can be accessed via browser: http://localhost:8080 # Chat completion endpoint: http://localhost:8080/v1/chat/completions ```
  • Support multiple-users and parallel decoding ```bash # up to 4 concurrent requests, each with 4096 max context llama-server -m model.gguf -c 16384 -np 4 ```
  • Enable speculative decoding ```bash # the draft.gguf model should be a small variant of the target model.gguf llama-server -m model.gguf -md draft.gguf ```
  • Serve an embedding model ```bash # use the /embedding endpoint llama-server -m model.gguf --embedding --pooling cls -ub 8192 ```
  • Serve a reranking model ```bash # use the /reranking endpoint llama-server -m model.gguf --reranking ```
  • Constrain all outputs with a grammar ```bash # custom grammar llama-server -m model.gguf --grammar-file grammar.gbnf # JSON llama-server -m model.gguf --grammar-file grammars/json.gbnf ```

llama-perplexity

A tool for measuring the perplexity ^1 of a model over a given text.

  • Measure the perplexity over a text file ```bash llama-perplexity -m model.gguf -f file.txt # [1]15.2701,[2]5.4007,[3]5.3073,[4]6.2965,[5]5.8940,[6]5.6096,[7]5.7942,[8]4.9297, ... # Final estimate: PPL = 5.4007 +/- 0.67339 ```
  • Measure KL divergence ```bash # TODO ```

llama-bench

Benchmark the performance of the inference for various parameters.

  • Run default benchmark ```bash llama-bench -m model.gguf # Output: # | model | size | params | backend | threads | test | t/s | # | ------------------- | ---------: | ---------: | ---------- | ------: | ------------: | -------------------: | # | qwen2 1.5B Q4_0 | 885.97 MiB | 1.54 B | Metal,BLAS | 16 | pp512 | 5765.41 ± 20.55 | # | qwen2 1.5B Q4_0 | 885.97 MiB | 1.54 B | Metal,BLAS | 16 | tg128 | 197.71 ± 0.81 | # # build: 3e0ba0e60 (4229) ```

llama-run

A comprehensive example for running llama.cpp models. Useful for inferencing. Used with RamaLama ^3.

  • Run a model with a specific prompt (by default it's pulled from Ollama registry) ```bash llama-run granite-code ```

llama-simple

A minimal example for implementing apps with llama.cpp. Useful for developers.

  • Basic text completion ```bash llama-simple -m model.gguf # Hello my name is Kaitlyn and I am a 16 year old girl. I am a junior in high school and I am currently taking a class called "The Art of ```

Seminal papers and background on the models

If your issue is with model generation quality, then please at least scan the following links and papers to understand the limitations of LLaMA models. This is especially important when choosing an appropriate model size and appreciating both the significant and subtle differences between LLaMA models and ChatGPT:

XCFramework

The XCFramework is a precompiled version of the library for iOS, visionOS, tvOS, and macOS. It can be used in Swift projects without the need to compile the library from source. For example:

// swift-tools-version: 5.10
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "MyLlamaPackage",
    targets: [
        .executableTarget(
            name: "MyLlamaPackage",
            dependencies: [
                "LlamaFramework"
            ]),
        .binaryTarget(
            name: "LlamaFramework",
            url: "https://github.com/ggml-org/llama.cpp/releases/download/b5046/llama-b5046-xcframework.zip",
            checksum: "c19be78b5f00d8d29a25da41042cb7afa094cbf6280a225abe614b03b20029ab"
        )
    ]
)

The above example is using an intermediate build b5046 of the library. This can be modified to use a different version by changing the URL and checksum.

Completions

Command-line completion is available for some environments.

Bash Completion

$ build/bin/llama-cli --completion-bash > ~/.llama-completion.bash
$ source ~/.llama-completion.bash

Optionally this can be added to your .bashrc or .bash_profile to load it automatically. For example:

$ echo "source ~/.llama-completion.bash" >> ~/.bashrc
