"The PaLM 2 pre-training corpus is composed of a diverse set of sources: web documents, books, code, mathematics, and conversational data" I really want to know more about the training data. Which web documents, which books, code from where, conversational data from where?

I fully expect Discord to be a data source, if not already, then for a future version. I also expect that the only way the general public would ever find this out is via whistle-blower.

The report specifically states: > The largest model in the PaLM 2 family, PaLM 2-L, is significantly smaller than the largest PaLM model but uses more training compute The largest PaLM model is 540B. So all of PaLM 2 is potentially double-digit parameters. Note though that GPT-3.5 was plausibly not a finetuning of the 175B model, but instead a finetuning of Codex which was based on the 12B version of GPT-3.

How could GPT-3.5 possibly have been a finetuning of the 175B model? They didn't even use the same tokens?

Finetuning might not be the best word; sometimes it is a grey line.

Token embeddings can be trained without changing the other parameters. There is a number of models which add tokens as a finetuning step. Here is recently StarCoder adding ChatML-equivalent tokens: https://huggingface.co/blog/starchat-alpha#a-standard-format...

Given Reddit's inability to keep their website functioning (unless you use the far superior old.reddit.com) I find it hard to believe they would be able to stop a motivated developer from scraping the whole site.

this is about the time that i expect sites to begin returning intentionally corrupt/incorrect/perhaps outright garbage (subtle or not, probably better subtle so they don't realize it until it's far too late) data in order to intentionally poison enemy wellscraping. where "ethics" dissolve into the inherent raw cannibalistic laws of capitalist ventures. then you can sell them back the TBs they scraped at a 1000x marku…

Maybe they've been doing that for years and that's why all the advice subreddits turned into creative writing subreddits.

I don't think you can do this, it will just make things up. Language models don't have this type of reflection. Google would need to indicate this out of band, like on the page itself, in order for you to be confident about what model you're using.

Agreed. I'm not entirely sure that the person you're replying to is not joking

I'm pretty sure they're trying to suggest that LLMs in general are not useful because they can't do this type of thing. It's just the next iteration of goal post moving and should effectively be ignored.

Many artists and such that I've spoken to about AI work have similar comments about these systems because of the disdain for their existence.

The number of times I hear an argument like "well, they can never taste the tartness of a kiwi and feel the heat of the sun while at the beach" gets quite exhausting. For some reason, many people have this weird notion that this is what AGI means - exactly what humans do, and specifically within the same data domains of humans, but they don't consider working solely outside those domains as a possibility for AGI.

Sure, you can add a few tokens, but in this case they changed almost every token.

You can verify that your Bard instance is using Palm 2 by asking “are you using the palm or palm 2 model?”

I've asked "are you using palm 3": It said: I am using the Palm 3 model. Palm 3 is a large language model... Don't believe it :) Also, In the technical report, It mentions multiple languages, I've asked in Turkish which was supposed to be supported, but wasn't able to answer. Even if its PaLM 2, its hard to trust to the model itself.

I asked it "are you using the palm 420 language model or the palm 2 language model?"

It said "I am not using either the Palm 420 language model or the Palm 2 language model. I am using a different language model called Bard, which is a large language model from Google AI."

Perhaps the people at Google saw this and made a manual correction? Hard to say, black boxes and all...

The thing is, once a company creates a proto AGI where the path to a functional AGI is entirely predictable with more compute, they'll keep it a secret. Who would share the fact that the greatest achievement in human history is possible when having it before anyone else gives you a huge competitive advantage?

I tried asking it "what is the difference between the palm language model and the bard language model?" and its reply started off "The main difference between the Palm language model and the Bard language model is the size of the dataset they are trained on. Palm is trained on a dataset of 400 billion parameters, while Bard is trained on a dataset of 540 billion parameters." Which to me is even more interesting that what the OP commenter asserted.

I don't understand how this can be considered a technical report. No information on model architecture, distributed training methodology, or optimizations. The "Training dataset" section is a pathetic 0.5 pages long.

Come on, Google.
