It's in the name of the model - "Vicuna-13B" implies there are 13 billion parameters.

the way these LLMs work, there is a weight for each parameter? 13 billion weights? what is an example of a parameter?

A parameter is a variable for which a weight (a floating point value) is the concrete value.

Essentially a computer neural network is just a lot of addition (and matrix multiplication) of floating point numbers. The parameters are the "strength" or "weights" of the connections between neurons on different layers and the "bias" of each neuron. If neuron Alice is connected to neuron Bob and Alice has a value of 0.7, and the weight of Alice's connection to bob is 0.5, then the value sent from Alice to Bob is 0.…

Why would a 4bit quantized model be less accurate than a 16?

Because 4 bits less precisely specifies the value of the parameter than 16 bits does.

Lemme save whoever is donating the legal here the time: model weights are definitely copyrightable.

> model weights are definitely copyrightable. on what legal theory or precedence makes this true? IMHO, the weights are akin to the list of telephone numbers in a directory - which is definitely not copyrightable; only the layouts and expressive portion of a phone directory is copyrightable. So to make the weights copyrightable, it needs to be argued that the 'layout' of the weight is a creative expression, rather th…

I agree but I'd suggest that weights are less like the telephone numbers in a directory and much more like the proportional weights in a recipe.

Recipes, famously, are almost but not quite copyrightable | patentable.

a weight is an example of a parameter

so is a bias, and presumably the biases are also in the same file with the weights

(I work on llama-dl.) We’re fighting back against the DMCA requests on the basis that NN weights aren’t copyrightable. This thread has details: https://news.ycombinator.com/item?id=35393782 I don't think you have to worry about Facebook going after you. The worst that will happen is that they issue a DMCA, in which case your project gets knocked offline. I don’t think they’ll be going the RIAA route of suing individu…

If they aren't copyrightable, couldn't they still be classes as a trade secret and still fall under IP law? Though I'm not sure if distributing the weights to people who sign a simple agreement to not redistribute would count as taking reasonable precautions in maintaining secrecy.

If facebook freely distributed their trade secrets, I'm not sure they'd have any legal defense.

Just when you think Nvidia will go down something happens that changes it. These days unless you were into gaming or a machine learning dev the integrated graphics were good enough. But now first time in a long time I am interested in getting a gpu for running some of these chatbots locally.

Is there some single page that keeps a running status of the various LLVM's and the software to make them runnable on consumer hardware?

Not a single page, but almost all large language models with open weights are published on this website: https://huggingface.co/models

This looks really good for a run-it-on-your-own-hardware model from the examples and sibling comments. I've been working on a pure AVX2 Rust implementation of LLaMA but was starting to lose interest and been waiting for whatever is the next hot downloadable model, but now I want to add this thing to it. I'll be busy next few days. Heck yeah.

Are you the GGML dev?
