GPT included a picture of the variation of the transformer model that they made.

GPT2 outlined the changes they made to the model in an acceptably moderate detail.

GPT3 references another paper saying "we use alternating dense and locally banded sparse attention patterns in the layers of the transformer, similar to the Sparse Transformer" with no detail added on the changes they made.

How are you to reproduce these results at all? You could attempt to include the changes as they references the sparse transformer paper, but you could possibly do it in a different way, and there would be no way to verify the results that they gave whatsoever due to changes in implementation.

A bit disappointing.

The full model of GPT-2 is available for inspection and retraining, if you so desire. GPT-3 will likely be released soon as well.

Even though this was the GPT-3-generated text that humans most easily identified as machine-written, I still like it a lot: Title: Star’s Tux Promise Draws Megyn Kelly’s Sarcasm Subtitle: Joaquin Phoenix pledged to not change for each awards event Article: A year ago, Joaquin Phoenix made headlines when he appeared on the red carpet at the Golden Globes wearing a tuxedo with a paper bag over his head that read, "I am…

What is it about ai generated texts that on skimming through it it makes sense, but if you try to slow down and understand it feels absurd and surreal.

Yup, definitely different from how humans learn. A baby's speech would be almost the complete opposite, grammatically incorrect here and there but constructing a coherent line of thought for the most part.

Likely, but in a released paper, there should be a bit more quality from a research standpoint.

Earlier quoted context omitted.

They can, they can crowd out good comments with an absolutely crushing volume of crap. While humans can put out a lot of crap, bots can do orders of magnitude more. The issue is that it is an effort multiplier for when a small number of people want to target a particular forum.

I imagine the problem isn’t so much volume of crap comments as much as the tailoring of crap comments. Imagine if every tweet-into-the-void from a human with 50 followers reliably got engaging replies. Bots taunting your grammar mistakes, bots selectively quoting your prior tweets to point out contradictions, bots cleverly insinuating that your tweets reveal problematic sympathies. So much of our noise-filtering is i…

If a person has any paranoid tendencies, this would be a psychological onslaught. Interrogators use the tactics you just described to siege a person to psychological exhaustion.

Product Devs for the CCP will have a lot to work with if this ever evolves.

This part really freaked me out... GPT-2 couldn't do math: Context → Passage: Saint Jean de Br´ebeuf was a French Jesuit missionary who travelled to New France in 1625. There he worked primarily with the Huron for the rest of his life, except for a few years in France from 1629 to 1633. He learned their language and culture, writing extensively about each to aid other missionaries. In 1649, Br´ebeuf and another missi…

Author here: Sorry for the confusing formatting on the task descriptions at the end of the paper. That "4" is the human-generated target completion, not a model generated completion. I'm not sure whether the model got that particular question correct, but from Table 3.7 that GPT-3 has 36.5% accuracy on DROP in the few-shot setting.

Many other readers were confused by this so we'll update the formatting to say "target completion" to make this more clear.

I am not a fan of this trend of "Language Models Are X" in recent work particularly out of OpenAI. I think it's a rhetorical sleight of hand which hurts the discourse.

Like, the exact same paper could have instead been titled "Few-Shot Learning with a Large-Scale Language Model" or similar. But instead there seems to be this extremely strong desire to see certain ineffable qualities in neural networks. Like, it's a language model. It does language modeling. Turns out you can use it for few-shot learning and do amazingly well. Beyond that, what does it mean to say it "is" a few-shot learner?

On one hand, it's literally the same claim in a strict sense. On the other hand, it implies something much broader and more sweeping, that language modeling / unsupervised learning as a task over long contexts inherently implies meta-learning ability — which is a statement that is very difficult to properly formulate, let alone back up. But that's the argument that I feel is being slipped under the table by these titles. (And indeed it's very close to what they suggest in the text, though with no more than a wave of the hands.)

Don't get me wrong: their intuition is reasonable, it's super cool that they got this to work, and the results are very impressive on lots of tasks (though there are clear gaps). But as a VERY publicly watched lab, they have a serious duty (which I think they're neglecting) to frame their results more carefully. In particular, there's a sort of religion that if you train a big enough model on big enough data with self-supervision, it will somehow become AGI and/or learn to solve arbitrary problems. Claims like "Language Models are Few-Shot Learners" are clearly designed to fit into that worldview, even though the research doesn't point at it any more than a more conservative interpretation like "Lots of NLP Tasks are Learned in the Course of Language Modeling and can be Queried by Example." They touch on this limitation in their discussion section but I guess flashy titles are more important. I wish they would use their status to set a better example.

I don't know if it says something about text generation or human text processing, but whenever I read an example of computer generated text, all through I think "I can't tell this is machine generated, it seems completely natural," and the only giveaway is that at the end I have no idea what it said.

It's a pretty eerie feeling. It's as though both the AI and my short-term processing only pay attention to a context of a few sentences, so nothing seems off until I try to understand it as a whole.

EDIT: Thinking more, what it feels like most of all is reading a page of a book and not taking it in.

Thanks for clarifying. I'm a bit more confused though, are you saying that all of these Q&A examples are human answered, and that you were just demonstrating the format / question types for Q&A? If so, is there any way to see some of the model's responses?

Thank you.

Earlier quoted context omitted.

It seems it has (rudimentarily) learned concepts general enough to be logic itself. That is general intelligence. Now hook it up to reinforcement circuitry and make it even larger and it will mark the end to life as we know it. GTP-3 has 175 billion parameters, but the human brain has 100 trillion synapses, so 0.175%. NN model capacity currently has a 3.4 month doubling time.[1] In 7-10 doublings we'll be in a simila…

Is there any specific reasoning behind equating 1 synapse to 1 NN parameter? Seems a bit simplistic. Seems to me like a synapse probably has more computational ability than a single parameter.

Real neurons have many other trainable parameters and a lot more computational structure, so this is of course a simplifying assumption, but it is not entirely baseless either as it is known ANNs can approximate any function in theory, which may suggest synaptic weights do the heavy lifting in biological brains (since what more than general do you need?).

Though biological brains are likely overly complicated due to evolutionary baggage. There are hydrocephalus cases which have much reduced brain matter, but still high IQ.[1] The recurrent laryngeal nerves in giraffes is about 4.6 metres (15 ft) because it goes up and down their neck as it could not be rewired more directly during evolution.[2] Our pristine mathematical models and low-noise computational environments are likely superior to evolved wetware hacks.
