Is it possible that some LLM’s are trained on these benchmarks? Which would mean they’re overfitting and are incorrectly ranked? Or am I misunderstanding these benchmarks?…

It would be a bit of a scandal, and IMO too much hassle to sneak in. These models are trained on massive amounts of text - specifically anticipating which metrics people will care about and generating synthetic data just for them seems extra. But not an expert or OP!

I don't think it's a scandal, it's a natural thing that happens when iterating on models. OP doesn't mean they literally train on those tests, but that as a meta-consequence of using those tests as benchmarks, you will adjust the model and hyperparameters in ways that perform better on those tests.

For a particular model you try to minimally do this by separating a test and validation set, but on a meta-meta level, it's easy to see it happening.

Google has far better models than llama based models. They just simply don't put them facing the public. It is pretty ridiculous that they essentially just set a marketing team with no programming experience to write Bard, but that shouldn't fool anyone into believing they don't have capable models in Google. If Deepmind were to actually provide what they have in some usable form, it would likely be quite good. Despi…

I’ve been hearing “Google has secret better models” for 7 months now. Maybe some UFOs in the hangers at Moffett Field too?

No

GPT models were internally available 6-12 months before they've seen public beta, of course OpenAI has more capable internal models.

There's no reason to believe this. The training time and cost is so substantial that they are almost certainly building their next release, but it isn't sitting there rotting.

Thanks for posting this ! I actually laughed outloud at the response

> Google's model is not as capable as llama-derived models, so I think they would actually benefit from this. Google's publically available model isn't as capable. But they certainly have models that are far better already in house.

Comments like this remind me of the old-timers from IBM saying "but wait, we invented the PC! and the cloud! and..." Gotta put products in the market, or it didn't happen...

bringing back PLOSTFU culture might not actually be a bad thing.

Could someone please give us non-practitioners a practical TLDR? Specifically, can I get this packaged somehow into a thing that I can run on my own server to classify my mail as spam or non-spam? Or at least run it as a service with an API that I can connect to? I watch the development of those LLMs with fascination, but still wade through tons of spam on a daily basis. This should be a solved problem by now, and it…

Preface: I`m no expert. What you are looking at here is a Natural Language Model. They are Chatbots. What you want is a classification model, the typical Spam filter is a Naive Bayes classifier. If you want to run a Natural Language Model at a meaningful speed and size on your server you probably need a high end consumer graphics card. If you want to run a Natural Language Model that is big you will need high end ser…

Zuck said it best, open-source is the differentiator in the AI race and they're really well-positioned for it. Though I'm not sure that was on purpose...

I think that makes it a better test. An ideal model would recognize the ambiguity and either tell you what assumption it's making or ask a followup question.

While that is true, I'm not aware of any model that has been trained to do that. And all models can do is to do what they were trained to do.

It's not model but working on top of it: https://www.phind.com/ It's asking clarifying questions.

How does one apply for a job with the the internal A16Z teams experimenting with this?

Ask Llama of course. Showing that you are willing to ask an LLM is a perfect sign for a candidate!

It’d be fun if they added Easter eggs to it just like how companies would advertise jobs in the browser console.

I guess the brains objective is wrong then seeing how much it's willing to fabricate sense data, memories and rationales when convenient

The brain wasn't designed.

The brain is the result of maximizing biological objective functions.

Since that led to something that fabricates a lot of things very often, saying the objective function of an LLM is "wrong" because it also fabricates is nonsensical.
