This is just stupid.

We've pumped more English through GPT-3 than any existing English-speaking human has absorbed in their entire lifetime, and what we've ended up with is something that very very clearly has so utterly failed to generalize even the most basic level of understanding of basic concepts that if you ask it to count the number of letters in a word it will cheerfully pump out the wrong answer ("there are thirteen letters in the word 'twelve'") because its dataset correlates the two words with one another and it has learned precisely sweet fuck all about what it means to count, something a child's brain picks up with exposure to many orders of magnitude fewer language examples.

To imagine your brain is just an LLM is to mistake your reflection for another person in the room. Utterly daft. Get off the LLM hype train and start looking at these things objectively and critically. They're nowhere near what you're imagining.

Not to be too blunt, but you seem to be talking out of your ass. I'm tired of the overly dismissive comments here on hackernews by people who didn't bother to do the bare minimum of research. LLMs do not work with individual characters, they use tokens (i.e multiple characters, or sometimes entire words).

Wow, you... completely misunderstood the purpose of that example.

Seriously, slow down and read it again, all the way to the end of that sentence.

Uh, no.. I don't believe I did. Asking it to count the letters in a word is like asking a human to listen for a 30kHz tone without them knowing that humans can't hear it. I'd expect a lot of false positives.
Which reinforces the point I was making. Stop trying to win an argument online and think for 5 seconds about what it means for the claim "the human brain is just an LLM" if you're arguing that an LLM is naturally ill-suited to this task human children can do without issue.
>the human brain is just an LLM

Never have I said such a thing. Also, BPEs aren't a natural limitation of any transformer-based model, it's a trick to save compute for LLMs.

So what is this supposed to mean?

Sure sounds like you're suggesting the brain is an LLM to me, and I can't blame bonsaibilly for thinking that.

Yep. It’s not called tokens for nothing.
Here is an objective and critical assessment of large language models and how to empirically improve the results of questions involving calculations like the lengths of strings:
