If your goal is
> I want to peel back the layers of the onion and other gluey-mess to gain insight into these models.
Then this is great.
If your goal is
> Run and explore Llama models locally with minimal dependencies on CPU
then I recommend https://github.com/Mozilla-Ocho/llamafile which ships as a single file with no dependencies and runs on CPU with great performance. Like, such great performance that I've mostly given up on GPU for LLMs. It was a game changer.

Ollama (also wrapping llama.cpp) has GPU support, unless you're really in love with the idea of bundling weights into the inference executable probably a better choice for most people.

Ollama is great if you're really in love with the idea of having your multi gigabyte models (likely the majority of your disk space) stored in obfuscated UUID filenames. Ollama also still hasn't addressed the license violations I reported to them back in March. https://github.com/ollama/ollama/issues/3185

I wasn't aware of the license issue, wow. Not a good look especially considering how simple that is to resolve.
The model storage doesn't bother me but I also use Docker so I'm used to having a lot of tool-managed data to deal with. YMMV.
Edit: Removed question about GPU support.

I think this is also a problem in a lot of tools, that is never talked about.
Even myself I’ve not thought about this so deeply, even though I am also very concerned about honoring other people’s work and that licenses are followed.
I have some command line tools for example that I’ve written in Rust that depend on various libraries. But because I distribute my software in source form mostly, I haven’t really paid attention to how a command-line tool which is distributed as a compiled binary would make sure to include attribution and copies of the licenses of its dependencies.
And so the main place where I’ve given more thought to those concerns is for example in full-blown GUI apps. There they usually have an about menu that will include info about their dependencies. And the other part where I’ve thought about it is in commercial electronics making use of open source software in their firmware. In those physical products they usually include either some printed documents alongside the product where attributions and license texts are sometimes found, and sometimes if the product has a display, or a display output, they have a menu you can find somewhere with that sort of info.
I know that for example Debian is very good at being thorough with details about licenses, but I’ve never looked at what they do with command line tools that compile third-party code into them. Like does Debian package maintainers then for example dig up copies of the licenses from the source and dependencies and put them somewhere in /usr/share/ as plain text files? Or do the .deb files themselves contain license text copies you can view but which are not installed onto the system? Or they work with software authors to add a flag that will show licenses? Or something else?

It's really something that should be abstracted by the linker. Codebases like zlib for example will just put a `const char notice[] = "Copyright Adler et al";` in one of their files so the license issue with zlib is solved simply by using zlib. However modern linkers have gotten so good that -fdata-sections -Wl,--gc-sections will strip that away and probably LTO too. In Cosmopolitan Libc I used to use the GNU assembler `.ident` directive in an asm() tag at the tops of .c files to automate license compliance. But some changes to ld.bfd ended up breaking that. Now I have to use these custom defines like https://github.com/jart/cosmopolitan/blob/706cb6631021bbe7b1... and https://github.com/jart/cosmopolitan/blob/706cb6631021bbe7b1... and https://github.com/jart/cosmopolitan/blob/706cb6631021bbe7b1... to get the job done. It really should be a language feature so that library authors can make it as simple as possible for users to comply with their license. I just don't think I've ever seen anyone think about it this way except for maybe Google's JavaScript minifiers, which is where I got the idea.

Llamafile is great if you don't want to run any meaningful models because it's limited to 4GB.

That's a Windows limitation, though.

Even on Windows, you just run the binary separate from the model file. I actually run a single binary separate from the model files because I run it with multiple of them, so I kind of forgot that that was even the default way it kind of expects you to hold it.

When I said
> such great performance that I've mostly given up on GPU for LLMs
I mean I used to run ollama on GPU, but llamafile was approximately the same performance on just CPU so I switched. Now that might just be because my GPU is weak by current standards, but that is in fact the comparison I was making.
Edit: Though to be clear, ollama would easily be my second pick; it also has minimal dependencies and is super easy to run locally.

A great place to start is with the LLaMA 3.2 q6 llamafile I posted a few days ago. https://huggingface.co/Mozilla/Llama-3.2-3B-Instruct-llamafi... We have a new CLI chatbot interface that's really fun to use. Syntax highlighting and all. You can also use GPU by passing the -ngl 999 flag.

„On Windows, only the graphics card driver needs to be installed if you own an NVIDIA GPU. On Windows, if you have an AMD GPU, you should install the ROCm SDK v6.1 and then pass the flags --recompile --gpu amd the first time you run your llamafile.”
Looks like there’s a typo, Windows is mentioned twice.

First time that I have a "it just works" experience with LLMs on my computer. Amazing. Thanks for the recommendation!

Do you have a ballpark idea of how much RAM would be necessary to run llama 3.1 8b and 70b on 8-quant?

Thanks for the suggestion. I've added a link to llamafile in the repo's README. Though, my focus was on exploring the model itself.

Can it use GPU if available, say on Apple silicon Macs

> GPU on MacOS ARM64 is supported by compiling a small module using the Xcode Command Line Tools, which need to be installed. This is a one time cost that happens the first time you run your llamafile.

I wonder if it's possible for llamafile to distribute without the need for Xcode Command Line Tools, but perhaps it's necessary for the single cross-platform binary.
Loved llamafile and used it to build the first version of https://recurse.chat/, but live compilation using XCode Command Line Tool is a no-go for Mac App Store builds (runs in Mac App Sandbox). llama.cpp doesn't need compiling on user's machine fwiw.

How great is the performance? Tokens/s?

Random sample query ("What shape should a kumquat be?") against a 7B model quantised to 4b running on an i7-9750H (so a good CPU, but also a good laptop CPU from 2019) gives:
148 tokens predicted, 159 ms per token, 6.27 tokens per secondbagels
