Out of curiosity, what's the file size on that?

Depends which model, but assuming the largest: 175B * 16 bits = 350GB. Half of that if it's quantized to 8 bits. Good luck finding a GPU that can fit that in memory.

I wonder if a 64GB Orin or M1 Max could fit the 30B model...

Don't worry, I'm sure they have some nefarious plans down the road. They're just being "open" to corner the market first.

> to corner the market first Is Meta's model going to be open source or paid?

The linked paper makes it clear it will be released under a non-commercial license. You will download it gratis (so it won't be paid), but it won't be open source.

>You cannot fingerprint models like this A GAN can absolutely be trained to discriminate between text generated from this model or another model. >that's hilarious What's hilarious about it?

That would be interesting if it was true, but I think it can’t be true because LLMs main advantage is they memorize text in their weights and so your discriminator model would need to be the same size as the LLM. That said the smaller GPT3 models break down quite often so they’re probably detectable.

In the same way we can train models that can identify people from their choice of words, phrasing, grammar, etc, we can train models that identify other models.

I often wonder if OpenAIs decision not to open gpt-3 was because it was to expensive to train relative to its real value. They’ve hidden the model behind an api where they can filter out most of the dumb behaviors, while everyone believes they are working on something entirely different.

I would like to know about the reason behind this as well.

I don't like "available on request". I just want to download it and see if I can get it to run and mess around with it a bit. Why do I have to request anything? And I'm not an academic or researcher, so will they accept my random request? I'm also curious to know what the minimum requirements are to get this to run in inference mode.

My bet it's probably a filter, trying to prevent create a even more realistic farmbots in social media, as they are already bad as they are now.

That is dumb when you consider that this thing is likely going to leak anyways. It’s inevitable, and when it does happen, it will just end up in the hands of criminals/scammers and not the general public.

A quick summary of the Limitations section: - "OPT-175B does not work well with declarative instructions or point-blank interrogatives." - "OPT-175B also tends to be repetitive and can easily get stuck in a loop. While sampling can reduce the incidence rate of repetitive behavior (Holtzman et al., 2020), we anecdotally found it did not eliminate it entirely when only one generation is sampled." - "We also find OPT-17…

AKA not as impressive as it sounds

The big one, OPT-175B, isn't an open model. The word "open" in technology means that everyone has equal access (viz. "open source software" and "open source hardware"). The article says that research access will be provided upon request for "academic researchers; those affiliated with organizations in government, civil society, and academia; and those in industry research laboratories.". Don't assume any good intent…

Add Mathematica to that list, too. Pretty cool to play with and I would have bought a license if I had a good excuse to; the tactic works.

Mathematica has been on my mind since high school because we got it for free. I went through the free trial process recently and tried a couple of things I have been too lazy to manually code up (some video analysis). It was too slow to be useful. My notebooks that were analyzing videos just locked up while processing was going on, and Mathematica bogged down too much to even save the notebook with its "I'm crashing, try and save stuff" mode. I ultimately found it a waste of time for general purpose programming; the library functions as documented were much better than library functions I could get for a free language, but they just wouldn't run and keep the "respond to the UI" thread alive.

So basically all their advertising money ended up being wasted because they can't fork off ffmpeg or whatever. Still very good at symbolic calculus and things like that, though.

It's super easy to watermark weights for ML models.

Just add a random 0.01 to a random weight anywhere in the network. It will have very little impact on the results, but will mean you can identify who leaked the weights.
