> god's work creating sentient life?

That can't be his work, since he only picked up that hobby about 0.000625% of the universe's timespan ago.

For many humans, some "hobbies" involve "projects" which may involve seemingly infinite degrees of procrastination. (This certainly applies to me!)

All of the llama derivatives are tainted by Meta's license, which makes commercial use illegal and even personal use dubious. Is all the training material used for Llama available as open source? Maybe lots of folks can pool their resources and create fully open clean models / weights instead.

That is, unless you can "clean room" an alternative while experimenting in secret with a Llama derivative.

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?

My lay-person's understanding is that it's due to the problem one is trying to solve with a deep learning model: draw a curve through the dimensions which separates "good" from "bad" activation values. The lower resolution the line, the higher likelihood the line will fit sometimes and veer off into erroneous space others

imagine trying to draw the blue line on the right using only lego blocks: https://youtu.be/QDX-1M5Nj7s?t=1202

Not a lawyer, but that still feels like dubious territory. I would still be on the hook for acquiring the original download, which Facebook has been launching dmca takedown requests for the llama-dl project.

(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…

I'm curious, do you not think this might have adverse effects? Namely, if NN weights aren't copyrightable, limited releases like Meta has done might not be possible anymore so they might just cease completely with releases, ultimately leading access to large models to be more restricted.

I think we already live in that era, unfortunately. Meta's model release is probably going to be the largest for some years.

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.

It's fairly similar to a ROM patch in the video game space, which has mostly stood the test of time.

With a ROM, you could at least make a claim that it was your backup copy. I have no such claims to Facebook’s model.

Researchers unaffiliated with Facebook are allowed to possess and use the original weights though, and they can make use of these weights.

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

Ok. What if I train it for one micro step?

This model is surprisingly resistant to jailbreaks. Can anyone get any to work via the web UI? https://chat.lmsys.org/ I tried a few from https://www.jailbreakchat.com/ and it refused them all. Interesting.

That might not be surprising considering these jailbreaks are written and tested specifically against ChatGPT and ChatGPT alone. This model probably has its own jailbreaks that would also be refused by ChatGPT

> 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 than a 'fact'. But the weights are matrices , which is not expressive or creative. Someone else could derive this exact same set of weights from scratch via the same algorithmic procedure, and therefore, these weights cannot be a creative expression.
