"Recent work has demonstrated substantial gains on many NLP tasks and benchmarks by pre-training on a large corpus of text followed by fine-tuning on a specific task. While typically task-agnostic in architecture, this method still requires task-specific fine-tuning datasets of thousands or tens of thousands of examples. By contrast, humans can generally perform a new language task from only a few examples or from simple instructions - something which current NLP systems still largely struggle to do. Here we show that scaling up language models greatly improves task-agnostic, few-shot performance, sometimes even reaching competitiveness with prior state-of-the-art fine- tuning approaches. Specifically, we train GPT-3, an autoregressive language model with 175 billion parameters, 10x more than any previous non-sparse language model, and test its performance in the few-shot setting. For all tasks, GPT-3 is applied without any gradient updates or fine-tuning. with tasks and few-shot demonstrations specified purely via text interaction with the model. GPT-3 achieves strong performance on many NLP datasets, including translation, question-answering, and cloze tasks, as well as several tasks that require on-the-fly reasoning or domain adaptation, such as unscrambling words, using a novel word in a sentence, or performing 3-digit arithmetic. At the same time, we also identify some datasets where GPT-3's few-shot learning still struggles, as well as some datasets where GPT-3 faces methodological issues related to training on large web corpora. Finally, we find that GPT-3 can generate samples of news articles which human evaluators have difficulty distinguishing from articles written by humans. We discuss broader societal impacts of this finding and of GPT-3 in general."

The summary:

- If you train a computer on a lot of words, it can do things a lot better

- In this case, the computer has learned how to translate languages, answer questions, and unscramble words

- It still has trouble with some things

- This is very interesting because it shows computers can do things which are very hard.

So here, it drops a lot of information (cloze tasks), and it adds some (that last point). But now I know what the paper is about in 10 seconds.

I go back and see that oh, "a lot of words" really means 10x the previous. I'm now hooked on what problems it has trouble with, and what problems it solves for humans.

I didn't know a thing about LLMs when I first read this. If I tried to read it top to bottom, I'd get stuck on "task-agnostic, few-shot performance" then "state-of-the-art fine- tuning approaches" then "an autoregressive language model". They're big words, but turns out they're not the interesting parts, and understanding what the paper is excited about helped me to understand the basics.
