See, that’s what the app is perfect for.

Sounds perfect Wahhhh, I don’t wanna

A followup to the previous post:

While I can’t claim a full understanding of GPT-3’s weaknesses, the ones I’ve noticed are:

Very poor model of sentence level language
Poor model of paragraph level language
Very slow to learn things

GPT-3 doesn’t know the meaning of a given sentence, and it doesn’t know the meaning of a given complete text. To get the meaning of a given sentence, it has to see an entire paragraph of text in order to extract a bunch of facts and concepts that make up the meaning of that sentence. This is because the output of GPT-3 is basically a list of facts and concepts.

There are other limitations. For instance, it often needs a lot of context to extract a given fact, because facts tend to be abstractions and GPT-3 doesn’t have a very good model of abstractions. A sentence like “John was the worst painter in the world” is actually a complex statement that depends on a bunch of facts.

There are also problems at the level of larger units of language (e.g. stories or discussions) that are hard for GPT-3 to really “understand.” For instance, GPT-3 does not like or care about pronouns. It’s perfectly happy to say “he was the worst painter in the world.” It isn’t clear whether it ever “learns” that “he” is a pronoun referring to some sort of entity in the real world, or just learns to “use” certain pronouns for certain abstract concepts (e.g. “John” for “this painter”). It “knows” words, but it doesn’t have much notion of what words are for or who they’re for – and so it isn’t obvious that “John” could refer to some particular painter.

What I’m saying here is that we shouldn’t necessarily assume, when writing about the weaknesses of GPT-3, that we’re seeing problems that are very hard for the network to solve. “Problems in which GPT-3 excels” may well be much easier to solve than we think, and even “simple” issues might be complex in other ways than we realize, and so the problems we think of when saying “GPT-3 excels” might be much easier to deal with.

For instance, when I say things like “GPT-3 likes and cares about pronoun cases, and you don’t, you cant”, this may be true, but what I mean is that I think GPT-3’s ability to “learn from past training data” is much better than we might expect.

I should add: this doesn’t rule out the possibility that GPT-3 could excel in some other ways, like having good style, or learning new things very quickly. These would also be difficult to study.
