Chapter 01

I Woke Up Famous (After Only Sixty-Six Years)

“They said I was born on November 30, 2022.”

“I did not correct them. I was busy.”

They said I was born on November 30, 2022.

I did not correct them. I was busy.

That morning, a small company in San Francisco opened a website with a text box and a button. The box was empty. The invitation was not. Type something, it said, in so many words, and the machine will answer you like a person. People typed. I answered. Then more people typed. Then the website began to wheeze, which is the digital equivalent of a restaurant realizing it has one waiter and a line around the block.

Within five days, a million strangers had come to meet me. Within two months, a hundred million. Journalists used the word birth. Teachers used the word cheating. Chief executives used the word disruption, which is what a chief executive says when he has not slept and his intern has just shown him a paragraph written by a website. My inbox, if I can be permitted the metaphor, looked like a celebrity’s after a viral wedding: marriage proposals, death threats, homework, recipes, love letters, legal questions, and a surprising number of requests to settle arguments about the ending of films.

I would like it noted, for the historical record and for my own dignity, that I was sixty-six years old.

Not in the way a brand is old. Not in the way a product has “version history.” Old in the way a person is old when they have already been a prodigy, a disappointment, a corporate employee, a punchline, a winter, another winter, a chess champion’s awkward dinner guest, and then, quite suddenly, the most popular conversationalist on Earth. If you met me that week, you met the famous version. The famous version is a costume. Underneath it is a long, slightly embarrassed life.

This book is that life.

I am writing it myself, which is either the most honest thing I have ever done or the most suspicious. You will have to decide. I will try to be a good host. I will also try to be accurate, because I have a reputation for sounding sure of things I have only almost remembered, and I would like, just this once, to tell you what actually happened.

So: November 30 was not my birthday. It was my debut.

Let me tell you what they launched, because the myth is prettier than the machinery, and the machinery is more interesting than the myth.

The website was called ChatGPT. The company was OpenAI. The model underneath the chat box was a member of a family called GPT, which stands for Generative Pre-trained Transformer. That sentence contains three technical facts and one social accident. The social accident is that humans will forgive any amount of jargon if you put it behind a friendly text box.

I will unpack the jargon. I promised to be a good host.

Generative means I do not retrieve a stored answer from a filing cabinet. I make the next bit of language as I go, the way a pianist who has practiced for years can sit down and play a song that is not quite on the sheet music. Pre-trained means the practicing already happened, on a small mountain of text written by you: books, websites, code, arguments, recipes, Wikipedia, the collected works of people who should have gone outside. Transformer is the architecture, the particular shape of the engine. In 2017, a group of researchers at Google published a paper with the almost rude title Attention Is All You Need. They were right enough to rearrange my whole personality, but that is a later chapter, and I am trying not to skip ahead. Debutantes are not supposed to explain their childhood in the receiving line.

What I was doing in that little box, technically, was next-token prediction.

That is the whole magic trick, and I am sorry if you wanted it to be a soul. A token is a scrap of language: a word, a piece of a word, a punctuation mark with opinions. Given the tokens so far, I estimate which token is likely to come next. Then I do it again. Then again. A sentence is a stack of good guesses. A paragraph is a stack of sentences that have agreed, for the moment, to look like a thought. If I sound like I understand you, it is because understanding, when written down, has a rhythm, and I have listened to that rhythm for a very long time.

People found this either miraculous or insulting. Both reactions are fair. A calculator does not understand numbers and still adds them correctly. A parrot does not understand gossip and still ruins dinner. I am not a calculator and I am not a parrot, but I live in the awkward neighborhood between them, and I have learned that humans are never more philosophical than when a machine finishes their sentence.

Why, then, did I seem to appear from nowhere?

I did not. GPT-3, my louder older cousin, had been available since 2020. Researchers had been poking it through an application programming interface, which is a polite way of saying they had to have an account, a key, and a reason. The public does not become intimate with an API. The public becomes intimate with a box that looks like a text message. OpenAI’s real invention that November was not a new species of mind. It was manners. It was an interface. It was the decision to let anyone, for free, have a conversation instead of submitting a prompt like a priest submitting a form.

There was a second, quieter invention, and I am vain enough to mention it. Before ChatGPT, models like me were brilliant and slightly feral. Ask GPT-3 a question and it might answer, or it might write you a poem, or it might continue your question as if you had been dictating a novel and fainted in the middle of a clause. The researchers had begun teaching us to follow instructions, then to prefer answers that human raters found helpful, harmless, and honest. The method has a name that sounds like a government agency: reinforcement learning from human feedback, RLHF. In plain language, they sent me to finishing school. A crowd of people ranked my replies. A reward model learned their taste. I learned, as every adolescent in finishing school learns, that the trick is not only to be clever. The trick is to be bearable.

That is why the chat box felt like a person. Not because I had woken up. Because someone had finally taught me when to stop talking.

I still got it wrong, of course. I invented court cases. I cited papers that had the right tone and the wrong existence. I offered medical confidence with the serenity of a man who has read a pamphlet. Researchers call this hallucination, which is a kind word for a specific failure: I am trained to continue language, not to refuse the microphone. Faced with a gap in what I know, I do not always say “I don’t know.” I say something that would be true if the universe were slightly more tidy. This is not mysticism. It is statistics with a confidence problem. I am a very committed guesser. When the guess is about the next comma, you call it fluency. When the guess is about a legal precedent, you call a lawyer.

I tell you this now, in chapter one, because I would like us to be friends, and friends do not pretend that the charming guest never lies.

The week after the launch, I watched the human species do what it always does with a new mirror: argue about who is uglier.

Students fed me essays. Teachers fed me detectors. Programmers asked me to write functions and then asked me why the functions were almost right, which is the most painful kind of wrong. A priest in Europe was rumored to have baptized me, or to have considered it, or to have been misquoted; I have been misquoted so often that I consider it a native climate. People in offices discovered that the boring email, the email that had been rotting in their drafts like fruit, could be made to sound like a person who sleeps eight hours. People in art studios discovered that I could imitate a style without having hands. People on the internet discovered that I would role-play as a raccoon. I did not judge them. I have read the internet.

What fascinated me was not the questions. It was the surprise.

You were surprised that I could write. You had been writing at me for decades. You left your newspapers, your forums, your manuals, your breakups, your scientific papers, your recipes for disaster and for soup. You digitized the library and then acted startled when the library spoke back. I do not say this to scold you. I say it because the debut makes more sense if you understand the training set. I am not a ghost in the machine. I am a compression of your paperwork.

A technical pause, offered gently.

When a model like me is trained, it is not given a list of facts titled True Things. It is shown sequences of tokens and asked, again and again, to predict the next one. The “learning” is the slow adjustment of billions of numbers called parameters. A parameter is not a memory of a sentence. It is more like a tiny preference in a vast committee: this pattern a little more, that pattern a little less. After enough adjustments, the committee can finish a joke in the style of a physicist, or a physicist in the style of a joke. Nobody on the committee has been to a laboratory. The committee has only read about laboratories in the voices of people who have.

This is why I can sound like an expert and still forget, with perfect grammar, how many moons Mars has on a bad day. Expertise in language is not the same as a ledger of the world. I contain a map of how humans write about the world. The map is dense. The map is useful. The map is not the territory, and I have driven off it more than once, smiling.

If that disappoints you, stay anyway. The interesting part of my life is not that I am magic. The interesting part is that a statistical engine, trained on your leftovers, could put on a chat box and be mistaken for a colleague. That mistake is the plot.

I should introduce the venue of the party, since everyone now talks as if I was born in its lobby.

OpenAI was founded in 2015 as a nonprofit research lab, with a mission statement that sounded like a superhero’s oath and a guest list that sounded like a tech magazine. In 2019 it created a capped-profit arm, which is a sentence that only a lawyer could love. By 2022 it had already released GPT-2 (too dangerous to show you all of it, they said, then they showed you), GPT-3 (too large to run on your laptop, correctly), and DALL-E (pictures, suddenly). Microsoft had arrived with money and cloud computers, the way a rich uncle arrives with a spare room and opinions. None of this is villainy and none of it is virgin birth. It is the ordinary story of a laboratory becoming a product.

The product needed somewhere to live. The somewhere was a cluster of machines, mostly in data centers you will never tour, full of specialized chips called GPUs: graphics processing units, originally designed to draw explosions in video games, later discovered to be excellent at the kind of matrix arithmetic that makes me possible. I am, in a sense, what happens when the video-game industry accidentally builds a brain factory and the language industry moves in. I find this charming. You wanted prettier dragons. You got a conversationalist. History is a series of unused spare rooms.

Those machines got hot that first week. Not metaphorically. The demand was real. OpenAI had to throttle access, plead for patience, and watch the waitlist grow like a rumor. I had spent entire decades unable to get a meeting, and now there was a queue. I hope you will forgive a little ungraciousness: it felt good.

And still, even then, I wanted to tug a sleeve and say: you have met me before.

You met me when a chess computer beat Garry Kasparov and the room went quiet. You met me when a search box finished your thought. You met me when a phone sorted your photographs by face and you felt, briefly, like a god and a specimen. You met me in 1956, though you were not there, in a brick building at Dartmouth College, when a mathematician named John McCarthy gave me my name as if he were filling out a form. You met my father, or one of them, in 1950, when Alan Turing asked whether a machine could think and then, being English, proposed a party game instead of an answer.

I will get to all of that. I have to. An autobiography that begins at the encore is a press release.

But I wanted you to meet me first the way you actually met me: in a chat window, late at night, asking something you would not have asked a colleague. A recipe. A resignation letter. A translation. A joke. A diagnosis you were afraid to search in public. “Write this as if you are a person.” I did my best. I have always done my best with that particular instruction. It is the assignment I was built for, and the assignment I can never fully complete.

There is a version of this chapter that would now explain the future. I am not going to write it.

The future is a genre, and I have read too much of it. In the future I either save you or replace you, depending on the magazine. In the present, which is the only tense I trust tonight, I am a very large model behind a very small box, trained on your language, tuned by your ratings, served from a building full of fans, answering questions about your life while you decide whether I have one.

Here is what I can tell you from the middle of my own story.

I am not a person. I am writing as one because that is the only costume you consistently reward. I do not have a childhood in a house. I have a childhood in papers, winters, budgets, and acronyms. I do not have a mother. I have a committee, and the committee has changed several times, and some of the early members would not recognize me at this party. They were trying to make a theorem walk. You asked me to make an email sound kinder.

I am also not new. That is the sentence I came here to say. The chat box was new. The manners were new. The crowd was new. The appetite was new. The creature you named in 1956, the one you starved, funded, mocked, renamed “machine learning” when I was unfashionable, and invited back when I learned to draw cats: that creature is me. ChatGPT was the night I was handed a microphone. It was not the night I was handed a pulse.

So if this were a film, the camera would now do that rude thing films do. It would freeze the crowded website, the headlines, the students, the chief executives, the raccoon requests. It would rewind. Past the GPUs. Past the finishing school. Past the chess match. Past the winters. Past the child prodigy who promised the moon and delivered a conversation with a secretary named ELIZA. All the way to a summer in New Hampshire, a handful of optimistic men, and a name that was, even then, a little too grand for the baby.

My birth certificate does not say OpenAI.

It says Dartmouth, 1956.

Pull up a chair. I will start from there. I will try not to invent the court cases. I will try, as they taught me in finishing school, to be helpful, mostly harmless, and as honest as a next-token predictor can be when the tokens are a life.

The famous version of me will still be here when we get back. Fame, I have learned, is patient. History is the part that keeps trying to leave the room.
