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

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.cppvia brew, flox or nix - Use a Docker image, see documentation for Docker
- Download pre-built binaries from releases
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 by using this CLI argument: -hf <user>/<model>[:quant]
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: ggml-org#10123)
- Use the GGUF-editor space to edit GGUF meta data in the browser (more info: ggml-org#9268)
- Use the Inference Endpoints to directly host
llama.cppin the cloud (more info: ggml-org#9669)

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
-cnvand specifying a suitable chat template with--chat-template NAMEllama-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
# 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-cnvllama-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
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/ folder contains a handful of sample grammars. To write your own, check out the GBNF Guide.

-
Start a local HTTP server with default configuration on port 8080
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

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:

- GPT-3
- GPT-3.5 / InstructGPT / ChatGPT:
