This is a private fork that I decided to make public due to it working better than I expected.
|
||||
|
||||
|
||||
Do I recommend you use this for anything important? No. Is it cool? I like to think so.

|
||||
## Quick start
|
||||
|
||||
Getting started with llama.cpp is straightforward. Here are several ways to install it on your machine:
|
||||
|
||||
- Install `llama.cpp` using [brew, nix, winget, or conda-forge](docs/install.md)
|
||||
- Run with Docker - see our [Docker documentation](docs/docker.md)
|
||||
- Download pre-built binaries from the [releases page](https://github.com/ggml-org/llama.cpp/releases)
|
||||
- Build from source by cloning this repository - check out [our build guide](docs/build.md)
|
||||
|
||||
Once installed, you'll need a model to work with. Head to the [Obtaining and quantizing models](#obtaining-and-quantizing-models) section to learn more.
|
||||
|
||||
Example command:
|
||||
|
||||
```sh
|
||||
# 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
|
||||
- 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 the main playground for developing new features for the [ggml](https://github.com/ggml-org/ggml) library.

## Obtaining and quantizing models
|
||||
|
||||
The [Hugging Face](https://huggingface.co) platform hosts a [number of LLMs](https://huggingface.co/models?library=gguf&sort=trending) compatible with `llama.cpp`:
|
||||
|
||||
- [Trending](https://huggingface.co/models?library=gguf&sort=trending)
|
||||
- [LLaMA](https://huggingface.co/models?sort=trending&search=llama+gguf)
|
||||
|
||||
You can either manually download the GGUF file or directly use any `llama.cpp`-compatible models from [Hugging Face](https://huggingface.co/) or other model hosting sites, by using this CLI argument: `-hf <user>/<model>[:quant]`. For example:
|
||||
|
||||
```sh
|
||||
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`. The `MODEL_ENDPOINT` must point to a Hugging Face compatible API endpoint.
|
||||
|
||||
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](https://github.com/ggml-org/ggml/blob/master/docs/gguf.md) 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](https://huggingface.co/spaces/ggml-org/gguf-my-repo) to convert to GGUF format and quantize model weights to smaller sizes
|
||||
- Use the [GGUF-my-LoRA space](https://huggingface.co/spaces/ggml-org/gguf-my-lora) to convert LoRA adapters to GGUF format (more info: https://github.com/ggml-org/llama.cpp/discussions/10123)
|
||||
- Use the [GGUF-editor space](https://huggingface.co/spaces/CISCai/gguf-editor) to edit GGUF meta data in the browser (more info: https://github.com/ggml-org/llama.cpp/discussions/9268)
|
||||
- Use the [Inference Endpoints](https://ui.endpoints.huggingface.co/) to directly host `llama.cpp` in the cloud (more info: https://github.com/ggml-org/llama.cpp/discussions/9669)
|
||||
|
||||

## 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
|
||||
// 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
|
||||
```bash
|
||||
$ 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:
|
||||
```console
|
||||
$ echo "source ~/.llama-completion.bash" >> ~/.bashrc
|
||||
```

`--longhaul-cache` is the expert cache budget in GiB. It is required when `--longhaul` is used. The same options are accepted by `llama-server`.
|
||||
|
||||
The command above runs every repeating layer on CPU and is supported on macOS,
|
||||
Linux, and Windows. On macOS, the existing all-Metal mode remains available by
|
||||
using `--n-gpu-layers 99` instead. Longhaul does not silently change device
|
||||
placement: an unsupported GPU or mixed CPU/GPU repeating-layer placement fails
|
||||
with guidance to use `--n-gpu-layers 0`.
|
||||
|
||||
Longhaul may reduce `--ubatch-size` so that every expert selected by one graph segment can be present in the cache at the same time. The effective value is logged during context creation. If one token selects more experts than the cache has slots, the routed MoE computation is split into multiple stages and the partial results are summed. This permits smaller caches at the cost of additional graph work.

||||
The normal startup warmup is skipped automatically in longhaul mode. Routed expert weights are not read until the first real decode.

Longhaul currently requires:

- all repeating layers on CPU, or all repeating layers on Metal
|

- Qwen3.5 MoE or Laguna architecture

- all repeating model layers assigned to Metal

- text generation without embeddings or LoRA adapters

|
||||
types must still be supported by the selected compute backend.
|
||||

MTP/speculative decoding, tensor validation during loading, vocabulary-only loading, and CPU or mixed CPU/Metal layer placement are not supported. Both single-file and split GGUF models are supported; routed expert tensors are read from the shard that owns each tensor.

The cache budget covers the compact routed-expert tensors. It does not include dense weights, attention weights, the KV cache, graph allocations, or the temporary buffer used for one expert read. Disk reads bypass the macOS unified file cache where supported, avoiding a second long-lived copy of streamed weights in system RAM.
|

The cache budget covers the compact routed-expert tensors. It does not include
|
||||
dense weights, attention weights, the KV cache, graph allocations, or temporary
|
||||
staging buffers. CPU expert caches use the standard directly writable tensor
|
||||
layout so individual slots can be replaced; optimized CPU buffer selection
|
||||
continues to apply to all non-streamed weights.
|
||||
|
||||
File-cache control is best effort and is outside the explicit cache budget.
|
||||
macOS disables caching for streamed files where supported, and Linux advises the
|
||||
kernel to discard completed reads. Windows may retain file data in its system
|
||||
cache. Windows reads from one GGUF shard are serialized to preserve positional
|
||||
read correctness, while POSIX systems retain concurrent `pread` operations.
|
||||
|
||||
This implementation synchronizes at each routed MoE layer to discover the selected experts, populate missing cache slots, and continue execution with cache-local expert IDs. Storage speed and expert reuse therefore have a large effect on generation speed.
|
||||
|
||||
Expert IDs are planned as a batch at each synchronization point. Experts already
|
||||
needed by that batch are protected from eviction, duplicate IDs are loaded only
|
||||
once, and independent expert slices are read concurrently on shared-memory Metal
|
||||
devices. Private Metal buffers use a staged fallback.
