* musa: build the docker image and CI container from the MUSA SDK images
Use registry.mthreads.com/mcconline/musa_sdk:5.2.0-{devel,runtime}-ubuntu22.04-s5000
instead of registry.mthreads.com/mcconline/inference/pytorch:2.9.1.post1-py3.10-musa5.2.0-mp31-devel-ubuntu22.04-amd64
for the MUSA docker image and the MUSA CI container, and let the runtime stage use the
runtime image instead of reusing the devel one, which drops the MUSA toolchain from the
published images.
* musa: install the MUSA headers and loader path the SDK images omit
musa_sdk:5.2.0-*-s5000 does not ship the cub and thrust headers that the MUSA
backend builds against, and its runtime image does not register
/usr/local/musa/lib with the dynamic loader.
Install both header packages in the build stage and in the MUSA CI container,
and write the loader path in the runtime stage.
* musa: install libmthreads-compute for the MUSA runtime library
The MUSA SDK images do not install libmthreads-compute, which provides
libmusa.so.1 in /usr/lib/x86_64-linux-gnu, so linking anything against the
MUSA backend fails.
* musa: install libmthreads-compute in the runtime stages
The MUSA runtime image does not install libmthreads-compute, so the published
images would have no libmusa.so.1 at run time.

llama.cpp
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:
- 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

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.
