Here is a photo of my family. I love them more than anything. Images have power, I hope. Normally we try to be pretty private, but in this case I am sharing a photo in the hopes that it might dissuade the next person from throwing a Molotov cocktail at our hou...

We have been learning quickly from how people are using Sora and taking feedback from users, rightsholders, and other interested groups. We of course spent a lot of time discussing this before launch, but now that we have a product out we can do more than just theorize....

We are launching a new app called Sora. This is a combination of a new model called Sora 2, and a new product that makes it easy to create, share, and view videos. This feels to many of us like the “ChatGPT for creativity” moment, and it feels fun and new....

Over the next couple of months, we’ll be talking about some of our plans and the partners we are working with to make this a reality....

Jakub is our chief scientist. He once described Szymon as “indefatigable”, which is as perfect of a use of that word as I have ever heard....

We are past the event horizon; the takeoff has started. Humanity is close to building digital superintelligence, and at least so far it’s much less weird than it seems like it should be. Robots are not yet walking the streets, nor are most of us talking to AI all day....

Our mission is to ensure that AGI (Artificial General Intelligence) benefits all of humanity. Systems that start to point to AGI* are coming into view, and so we think it’s important to understand the moment we are in....

The second birthday of ChatGPT was only a little over a month ago, and now we have transitioned into the next paradigm of models that can do complex reasoning....

There are two things from our announcement today I wanted to highlight. First, a key part of our mission is to put very capable AI tools in the hands of people for free (or at a great price)....

Optimism, obsession, self-belief, raw horsepower and personal connections are how things get started. Cohesive teams, the right combination of calmness and urgency, and unreasonable commitment are how things get finished....

Today we did a research launch of DALL•E 2, a new AI tool that can create and edit images from natural language instructions. Most importantly, we hope people love the tool and find it useful. For me, it’s the most delightful thing to play with we’ve created so far....

The most common question prospective startup founders ask is how to get ideas for startups. The second most common question is if you have any ideas for their startup. But giving founders an idea almost always doesn’t work....

I’m trying to fund startups/projects helping with COVID-19, because it’s basically the one thing I know how to do that can help....

The most counterintuitive secret about startups is that it’s often easier to succeed with a hard startup than an easy one. A hard startup requires a lot more money, time, coordination, or technological development than most startups....

Today, OpenAI released a new result. We used PPO (Proximal Policy Optimization), a general reinforcement learning algorithm invented by OpenAI, to train a team of 5 agents to play Dota and beat semi-pros....

I made a point in this post inelegantly in a way that was easy to misunderstand, so I’d like to clarify it. I didn’t mean that we need to tolerate brilliant homophobic jerks in the lab so that we can have scientific progress....

Earlier this year, I noticed something in China that really surprised me. I realized I felt more comfortable discussing controversial ideas in Beijing than in San Francisco. I didn’t feel completely comfortable—this was China, after all—just more comfortable than at home....

A popular topic in Silicon Valley is talking about what year humans and machines will merge (or, if not, what year humans will get surpassed by rapidly improving AI or a genetically enhanced species). Most guesses seem to be between 2025 and 2075....

I’d like feedback on the following idea. I think that every adult US citizen should get an annual share of the US GDP. I believe that owning something like a share in America would align all of us in making the country as successful as possible—the better the...

I'm a strong believer in the importance of the internet in helping people to share knowledge and learn from each other. So I’m delighted to share, on behalf of YC Continuity, that we’re investing alongside Collaborative Fund in Quora. Quora is doing extremely well....

Dear YC Community: In response to a comment on Hacker News, I’m going to try writing an annual letter to the YC community with an update on our progress. Our mission is to enable the most innovation of any company in the world in order to make the future great for everyone....

First of all, congrats to Kyle, Dan, and the rest of the Cruise team. You all have made amazing progress and we look forward to seeing more in the future....

Commentators are looking hard for what’s wrong with startups in Silicon Valley. First they talked about valuations being too high. Then they talked about valuations not really meaning anything. Then they talked about companies staying private too long....

Some of these are probably apocryphal, but making predictions about the limits of technology is really hard: Space travel is utter bilge. - Popular Mechanics, 1949 X-rays are a hoax. - Lord Kelvin, ca....

This is part two of a a two-part post—the first part is here. THE NEED FOR REGULATION Although there has been a lot of discussion about the dangers of machine intelligence recently, there hasn’t been much discussion about what we should try to do to mitigate the threat....

This is going to be a two-part post—one on why machine intelligence is something we should be afraid of, and one on what we should do about it....

In human history, there have been three great technological revolutions and many smaller ones. The three great ones are the agricultural revolution, the industrial revolution, and the one we are now in the middle of—the software revolution....

The most important story of 2014 that most people ignored was the Chinese economy overtaking the US economy. (This is using the purchasing power parity metric, which incorporates differences in the price of goods, but the Chinese economy will overtake on other...

One of the most common misconceptions startups have about applying to Y Combinator is thinking that they are too early or too late....

The YC application deadline is this Friday, and you can apply here. People often tell us they think they want to start a company but just aren’t sure, so I thought I’d share some thoughts....

On the whole, I got a great response to my request for feedback about how YC could encourage female founders. It's clear there are two separate problems: 1) Some women already starting startups aren't interested in doing Y Combinator....

We’d like for Y Combinator to fund more breakthrough technology companies—companies that solve an important problem, have a very long time horizon, and are based on an underlying technological or scientific breakthrough....

Nearly 5 years ago, Paul Graham first proposed the founder visa. There has been a lot of discussion since, but nothing has happened. Maybe he was too ambitious in asking for 10,000 startup visas per year....

Yesterday at lunch a friend asked me what tech trend he should pay attention to but was probably ignoring.

I frequently get asked by non-technical solo founders if I know any potential hacker cofounders they should talk to. These people give a passionate pitch for the idea and a long list of all the hustling they've done, customers they've spoken to, models they've...

A friend recently asked me for my list of current breakout companies. I made it, and noticed that all of them had only one thing in common....

There’s a lot of debate about whether or not the pace of innovation has slowed, and if so, what that means. After some particularly brutal pitches that felt like Saturday Night Live parodies of startups, I feel compelled to weigh in....
