GPT-3: Language Models are Few-Shot Learners (Paper Explained)
How far can you go with ONLY language modeling? Can a large enough language model perform Natural Language Processing (NLP) task out of the box? OpenAI take on these and other questions by training a transformer that is an order of magnitude larger than anything that has ever been built before and the results are astounding.

GPT-3 from OpenAI is here and it's a MONSTER!
GPT-3 is the largest language model to date with 175 billion parameters. It is able to do various Natural Language Processing (NLP) tasks (translation, question answering) without additional finetuning.

GPT-3 vs Human Brain
GPT-3 has 175 billion parameters/synapses. Human brain has 100 trillion synapses. How much will it cost to train a language model the size of the human brain? REFERENCES:

Steve Omohundro on GPT-3
In this research meeting, guest Stephen Omohundro gave a fascinating talk on GPT-3, the new massive OpenAI Natural Language Processing model. He reviewed the network architecture, training process, and results in the context of past work. There was extensive discussion on the implications for Natural_Language_Processing_(NLP) and for Machine Intelligence / AGI.

GPT 3 Demo and Explanation - An AI revolution from OpenAI
GPT 3 can write poetry, translate text, chat convincingly, and answer abstract questions. It's being used to code, design and much more. I'll give you a demo of some of the latest in this technology and some of how it works. GPT3 comes from a company called OpenAI. OpenAI was founded by Elon Musk and Sam Altman (former president of Y-combinator the startup accelerator). OpenAI was founded with over a Billion invested to collaborate and create human-level AI for the benefit of society. GPT 3 has been developed for a number of years. One of the early papers published was on Generative Pre-Training. The idea behind generative pre-training (GPT) is that while most AI's are trained on labeled data, there's a ton of data that isn't labeled. If you can evaluate the words and use them to train and tune the AI it can start to create predictions of future text on the unlabeled data. You repeat the process until predictions start to converge. The newest GPT is able to do a ton. Some of the demos include: - GPT 3 demo of how to design a user interface using AI - GPT 3 demo of how to code a react application using AI - GPT 3 demo of an Excel plug-in to fill data using AI - GPT 3 demo of a search engine/answer engine using AI - GPT3 demo of command line auto-complete from English to shell commands

Panel discussion - GPT-3 and Artificial General Intelligence 27 Aug 2020
Is GPT-3 a step towards creating artificial general intelligence? Chair: Associate Professor Kate Devitt - Chief Scientist, Trusted Autonomous Systems

Panel: • Professor David Chalmers (NYU) • Professor Susan Schneider (NASA and Florida Atlantic University) • Professor Marcus Hutter (ANU)

A philosophical discussion on the development of artificial intelligence and specifically advances in Generative Pre-trained Transformer-3 (GPT-3). GPT-3 is an auto-complete algorithm created by OpenAI as part of their endeavour to develop artificial general intelligence. GPT-3 is the third in a series of autocomplete tools designed by OpenAI. (GPT stands for “generative pre-trained transformer.”). GPT-3 is fed on an unimaginatively large corpus of human knowledge including all of Wikipedia, millions of books, websites and other materials including philosophy texts. In fact, any type of information uploaded to the internet is possible food for GPT-3's artificial mind to dwell on. The result? Eerily coherent, complex and interesting thoughts about almost any topic. The sophisticated, nuanced text produced by GPT-3 seems to pass the Turing Test for many--including philosophers. Some of GPT-3's answers are shedding new light on enduring philosophical questions. Is GPT-3 the beginnings of an artificial general intelligence. Does it create ideas like a human mind, or even better than a human mind? Is human cognition similarly some sort of autocomplete program in our brains? Is it possible that GPT-3 one day becomes consciousness or is it already conscious?--How could we tell. If an AI passes our tests for consciousness, do we then have an obligation to accord it rights? If so, what sorts of rights might it deserve. Independently of rights, how should humans manage an AI that has access to everything that is posited and known and can trick humans into believing that another rational agent is communicating with them? The panel considers what GPT-3 tell us about the ambition to build an artificial general intelligence, consciousness, human thought and how we should treat AI in an increasingly digital and disembodied world rife with mis- and disinformation.

Build 2 projects using GPT-3 in just a couple of minutes. Bare bones: branding generator, chat bot
Co-founded by Elon Musk OpenAI wants to make AI safe and accessible. A year ago the startup released GPT-2. That language model was at that time deemed too powerful to release. Eventually OpenAI made the model available. This year they've trained a much more powerful model at least 1 magnitude larger than GPT-2. I was one of the lucky 750+ people granted access as Beta testers by OpenAI to see what can be built using the GPT-3 API. The model costs millions of dollars to train which makes it out of reach for most organizations. This video skims the surface of what you can get done with this amazing new model.

Let's build GPT: from scratch, in code, spelled out - Andrej Karpathy

Let's build GPT: from scratch, in code, spelled out.
Andrej Karpathy ...We build a Generatively Pretrained Transformer (GPT), following the paper "Attention is All You Need" and OpenAI's GPT-2 / GPT-3. We talk about connections to ChatGPT, which has taken the world by storm. We watch GitHub Copilot, itself a GPT, help us write a GPT (meta :D!) . I recommend people watch the earlier makemore videos to get comfortable with the autoregressive language modeling framework and basics of tensors and PyTorch nn, which we take for granted in this video.

Suggested exercises:

  • EX1: The n-dimensional tensor mastery challenge: Combine the `Head` and `MultiHeadAttention` into one class that processes all the heads in parallel, treating the heads as another batch dimension (answer is in nanoGPT).
  • EX2: Train the GPT on your own dataset of choice! What other data could be fun to blabber on about? (A fun advanced suggestion if you like: train a GPT to do addition of two numbers, i.e. a+b=c. You may find it helpful to predict the digits of c in reverse order, as the typical addition algorithm (that you're hoping it learns) would proceed right to left too. You may want to modify the data loader to simply serve random problems and skip the generation of train.bin, val.bin. You may want to mask out the loss at the input positions of a+b that just specify the problem using y=-1 in the targets (see CrossEntropyLoss ignore_index). Does your Transformer learn to add? Once you have this, swole doge project: build a calculator clone in GPT, for all of +-*/. Not an easy problem. You may need Chain of Thought traces.)
  • EX3: Find a dataset that is very large, so large that you can't see a gap between train and val loss. Pretrain the transformer on this data, then initialize with that model and finetune it on tiny shakespeare with a smaller number of steps and lower learning rate. Can you obtain a lower validation loss by the use of pretraining?
  • EX4: Read some transformer papers and implement one additional feature or change that people seem to use. Does it improve the performance of your GPT?
