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 MTT 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.

Building and usage

The main product of this project is the llama library. Its C-style interface can be found in include/llama.h. The project also includes many example programs and tools using the llama library. The examples range from simple, minimal code snippets to sophisticated sub-projects such as an OpenAI-compatible HTTP server. Possible methods for obtaining the binaries:

• Clone this repository and build locally, see how to build
• On MacOS or Linux, install llama.cpp via brew, flox or nix
• Use a Docker image, see documentation for Docker
• Download pre-built binaries from releases

Obtaining and quantizing models

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

• Trending
• LLaMA

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:

• Use the GGUF-my-repo space to convert to GGUF format and quantize model weights to smaller sizes
• Use the GGUF-my-LoRA space to convert LoRA adapters to GGUF format (more info: https://github.com/ggerganov/llama.cpp/discussions/10123)
• Use the GGUF-editor space to edit GGUF meta data in the browser (more info: https://github.com/ggerganov/llama.cpp/discussions/9268)
• Use the Inference Endpoints to directly host llama.cpp in the cloud (more info: https://github.com/ggerganov/llama.cpp/discussions/9669)

To learn more about model quantization, read this documentation

Using the llama-cli tool

Run a basic text completion:

llama-cli -m your_model.gguf -p "I believe the meaning of life is" -n 128

# Output:
# 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.

See this page for a full list of parameters.

Conversation mode

Run llama-cli in conversation/chat mode by passing the -cnv parameter:

llama-cli -m your_model.gguf -p "You are a helpful assistant" -cnv

# Output:
# > 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!

By default, the chat template will be taken from the input model. If you want to use another chat template, pass --chat-template NAME as a parameter. See the list of supported templates

llama-cli -m your_model.gguf -p "You are a helpful assistant" -cnv --chat-template chatml

You can also use your own template via in-prefix, in-suffix and reverse-prompt parameters:

llama-cli -m your_model.gguf -p "You are a helpful assistant" -cnv --in-prefix 'User: ' --reverse-prompt 'User:'

Constrained output with grammars

llama.cpp can constrain the output of the model via custom grammars. For example, you can force the model to output only JSON:

llama-cli -m your_model.gguf -n 256 --grammar-file grammars/json.gbnf -p 'Request: schedule a call at 8pm; Command:'

The grammars/ folder contains a handful of sample grammars. To write your own, check out the GBNF Guide.

For authoring more complex JSON grammars, check out https://grammar.intrinsiclabs.ai/

Web server (llama-server)

The llama-server is a lightweight OpenAI API compatible HTTP server that can be used to serve local models and easily connect them to existing clients.

Example usage:

llama-server -m your_model.gguf --port 8080

# Basic web UI can be accessed via browser: http://localhost:8080
# Chat completion endpoint: http://localhost:8080/v1/chat/completions

Perplexity (measuring model quality)

Use the llama-perplexity tool to measure perplexity over a given prompt (lower perplexity is better). For more information, see https://huggingface.co/docs/transformers/perplexity.

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:

• LLaMA:
  • Introducing LLaMA: A foundational, 65-billion-parameter large language model
  • LLaMA: Open and Efficient Foundation Language Models
• GPT-3
  • Language Models are Few-Shot Learners
• GPT-3.5 / InstructGPT / ChatGPT:
  • Aligning language models to follow instructions
  • Training language models to follow instructions with human feedback
