My first public release of [Last-llama.cpp.zig](https://github.com/AktionStudio/last-llama.cpp.zig), a standalone Windows runtime

and CLI for running local GGUF language models with Zig and `llama.cpp`.

It provides separate CPU and NVIDIA CUDA workers, a simple command-line

interface, and a versioned JSON-lines protocol that Zig applications can call

directly. It supports explicit backend selection, structured JSON output,

model aliases, lifecycle cleanup, and runtime/model identity information. It

does not download models automatically or require a hosted model API,

users supply their own GGUF model.

This started as a small part of a much larger system I am building. I needed

more control over local models than I was getting through third-party services,

especially around the exact model, backend, structured output, lifecycle, and

evidence of what actually ran. I found [`Deins/llama.cpp.zig`](https://github.com/Deins/llama.cpp.zig), which showed me

that the Zig- to-`llama.cpp` bridge was possible and inspired the early work.

The active interface was later replaced with a narrower project owned

implementation, while retaining the original attribution and provenance.

I am sharing this mainly because it might save another Zig developer some work

or provide a useful starting point for a local model integration. This is not a

promise that I will maintain it indefinitely; my main focus remains the larger

project it came from. If it is useful to you, please feel free to fork it,

adapt it, and take it in the direction you need.

The current v0.1.0 release is **unsigned**, targets **Windows x64**, and includes

both CPU and CUDA support. Prebuilt binaries, source archives, checksums, and

qualification records are available on the

github .com/ AktionStudio/last-llama.cpp.zig/releases

The qualified source build uses Zig

`0.17.0-dev.1676+c9dc9b798`. Reproducing the generated C header binding uses Zig

`0.14.1` as a separate documented helper. Users of the prebuilt Windows package

do not need Zig installed.

I am working on a simulator platform and needed this to work with my project which

also is being made using Zig.

This project was mainly motivated by my ADHD ignoring some paper work

and a substantial amount of AI tools were used during code and architecture

analysis, implementation and refactoring, testing, release engineering, and documentation.

I am putting it out publicly because it may be useful to somebody

else. If it is not a fit for this Showcase, that is completely fine; the intent

is simply to share the work rather than leave a potentially useful component

buried inside a private project.

Have Fun!
