What is really impressive about this project and llama.cpp as well is that they keep finding new ways to speed up the code on the same hardware. Every time I upgrade (once a month or so) there is usually a 5 to 10% speed boost.
edit: Just to verify: I had planned to upgrade today, ran my usual benchmark prior and after and the runtime went from 4:22 to 3:59. That's a really long prompt (50K tokens) so prefill is a good chunk of that and the rest is spent on token generation.
Totally, I’ve been fiddling with local models on my machine (16GB AMD GPU + 64GB DDR4) for a few years and it’s remarkable the pace of improvement in what I can run. It has gone from complete novelty/useless to legitimately capable models running fast enough and with a big enough context to be useful running in a coding harness on a real codebase. A lot of that is down to the models themselves and the people making quants, but it feels like every time I pull llama.cpp changes and rebuild I get more performance and capability.
While I think that llama.cpp is an outstanding project - a one-stop-shop to get almost any model to run on almost any hardware, you get a lot more speed from specialised inference engines with kernels made for your hardware.
But if you don't have time to evaluate other engines and you simply want a rock solid inference engine, then llama.cpp is one of the best ones to go to.
> you get a lot more speed from specialised inference engines with kernels made for your hardware.
Of course you will. But that's not the point. The point is that Llama runs just about every model on just about every hardware. You can always improve on any metric by dropping that constraint. But there are a lot of such metrics:
- ease of use
- range of hardware
- accuracy of results
- range of models
Probably others. Llama.cpp may not be best at any one of those. But across all of them it has been consistently good. They've shown they're willing to stay the course as well. This is a foundation level project much like Linux or Apache.
I run vllm and llama.cpp; llama.cpp is pretty hackable by a local agent and is fast to start up, while vllm takes and age to build its optimized cuda graph.
The result is I run my big model (glm 5.3 flash) on llama.cpp and my small utility model (Qwen3 vl 8b) on vllm. Qwen often has better vision than glm (despite the tiny size) and can respond to tool calls from glm and importantly it doesn't use gobs of prefill+kv and is super fast.
Long time llama.cpp user (and user of other ggml based AI programs) running on my crappy AMD card that only supports vulkan and it's usable thanks to GGML and llama.cpp, great program great project.
If you load an MoE model that slightly exceeds your GPU memory budget, llama.cpp and ggml v1.0.0 can cache less-frequently used experts in host memory rather than failing to load.
"""
Description
The main goal of ggml is to be a simple, portable, and efficient tensor library for machine learning with minimal setup.
Plain C/C++ implementation without any dependencies
Cross-platform - x86, ARM, RISC-V, LoongArch, PowerPC, s390x, and WebAssembly
SIMD-optimized kernels for x86, ARM, and RISC-V
Broad backend support - CPU, GPU, NPU, and browser
2- to 8-bit integer quantization, plus MXFP4 and NVFP4 microscaling formats
Zero memory allocations during runtime
"""
As a mainframer, love to see the s390x support and zdnn (C library with all the instructions for our on chip accelerators) support. I like that IBM and Broadcom et al. went with something open source and local that could be tested on our Linux machines so that it wouldn't be a big pain to implement on z/OS or zLinux so to speak.
I've had the opportunity to do some fun playing around with zdnn on a z17. I've not tried the Spyre cards, but the on chip accelerator for Telum II is surprisingly capable with smaller models. I initially thought you would basically NEED the Spyre cards to get anything significant running but I was wrong.
I've been running llama.cpp on a plain CPU-only box for local work for over a year now, and the thing that keeps surprising me is how often an upgrade is just free performance. Same model, same hardware, noticeably faster prompt processing — jacquesm's 4:22 to 3:59 matches what I've seen on my own machine. The other underrated part is that the codebase is small enough to actually read. When something is slow I can usually find the hot loop myself instead of treating the inference engine as a black box, which is not something I can say about most of the GPU stacks I've used.
Congratulations on 1.0, and thanks to everyone who's worked on ggml. It's impressive how much it keeps improving on the same hardware. I'm curious whether 1.0 also comes with a stability commitment for the public C API. I've been looking at Python bindings to embed llama.cpp in-process, and knowing the API is stable until a 2.0 would make building on top of it much easier.
There's ample precedent for this. When you're building something to scratch an itch, the name is secondary. You cast about for one. Ah, you have a name. That'll do.
For example, DJ Delorie's djgpp project, built in 1989, was how I got into "real" programming on MS DOS.
Fun story time. I started programming on Turbo Pascal. I had read some C code from those demo scene guides, so felt I understood it fairly well by the time I got my hands on a copy of djgpp. I decided to port a relatively simple program I had written in Turbo Pascal, about 300 LOC, line-by-line. It was a small demo just doing a simple rotating, texture-mapped triangle.
I carefully converted it, and went over it several time one line at a time, fixing it until I had read over it three times and was happy.
I then ran the djgpp compiler...
Now, what I hadn't realized at the time was the difference between C and C++. The examples I had seen was C, and I didn't really know what C++ was.
The compiler churned on my code and spit out about 3500 errors and warnings (it counted for me).
I was shocked. How did my 300 line C program manage to produce over 10 errors and warnings per line, on average?!
I spent a long time trying to figure this one out. The first error was inside the first function, and the error made no sense to me.
After several days of carefully going over each line and banging my head against the table, I suddenly saw it. There, at the very start of the program, before the line the first error or warning pointed to.
In Turbo Pascal I had used const to define things like screen width and height. So I'd have
I removed the two semi-colons and the program compiled and ran just fine...
I ended up staying in Turbo Pascal, I preferred a compiler that gave me sensible errors and quickly. I did pick up C++ much later, and I guess ironically came to appreciate its const correctness.

Spawning the cli to server routing everything to http it complicates it instead of keeping it simple. This is pure telemetry or in plain english Spying on users. Rip LLama.cpp.
They were already doing that by making the build process phone home to Huggingface and also download huge swathes of indecipherable JavaScript (3 of those have been backdoored a month ago and only version pinning saved downstream).
Yes there is much more I forgot to mention (you nailed some of it), but as I already said, everyone has a price. Although it remains a piece of engineering that empowered users certainly.
Anyway we managed to eliminate all unpleasantries and have a clean CLI. I leave the server to whom may like it. Hit me up if you want to test it.

Why is this getting downvoted? That’s my grief with most landing pages, including popular ones which I simply get in contact with for the first time. Most of them somehow expect that you know the domain already. And even then, it wouldn’t hurt to simply state once in which context you want to provide what kind of solution.
tbh I much prefer this than another claude slop landing page. Not saying it couldn't be better but its kinda refreshing, the whole thing fits on my phone screen

I have an Intel Arc Pro B70. Serves me well! I use Qwen 3.8 27B
Wishing you unlimited power and may you never see a day of low battery. Respect and Love. Keep it up.

I'm glad their philosophy extends to the website as well. Genuinely refreshing.

holy fucking shit I just checked and they really did this LOL (https://github.com/ggml-org/llama.cpp/pull/17824)
good thing i'm never touching that repo ever again, or only to steal implementations
That seems borderline perfect to me.
Besides, some fancy AI generated landing page would signal even lower effort.
