Reading Time: 5 minutesOur 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. AGI is a weakly defined term, but generally speaking we mean it to be a system that […]
Reflections
Reading Time: 7 minutesThe 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. New years get people in a reflective mood, and I wanted to share some personal thoughts about how it has gone so far, and some of […]
GPT-4o
Reading Time: < 1 minuteThere 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). I am very proud that we’ve made the best model in the world available for free in […]
What I Wish Someone Had Told Me
Reading Time: 2 minutesOptimism, 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. Long-term orientation is in short supply; try not to worry about what people think in the short term, which will get easier over time. It […]
Helion Needs You
Reading Time: 2 minutesHelion has been progressing even faster than I expected and is on pace in 2024 to 1) demonstrate Q > 1 fusion and 2) resolve all questions needed to design a mass-producible fusion generator. The goals of the company are quite ambitious—clean, continuous energy for 1 cent per kilowatt-hour, and the ability to manufacture enough power […]
DALL•E 2
Reading Time: 2 minutesToday 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. I find it to be creativity-enhancing, […]
Helion
Reading Time: < 1 minuteI’m delighted to be investing more in Helion. Helion is by far the most promising approach to fusion I’ve seen. David and Chris are two of the most impressive founders and builders (in the sense of building fusion machines, in addition to building companies!) I have ever met, and they have done something remarkable. When […]
The Strength of Being Misunderstood
Reading Time: 2 minutesA founder recently asked me how to stop caring what other people think. I didn’t have an answer, and after reflecting on it more, I think it’s the wrong question. Almost everyone cares what someone thinks (though caring what everyone thinks is definitely a mistake), and it’s probably important. Caring too much makes you a […]
PG and Jessica
Reading Time: 2 minutesA lot of people want to replicate YC in some other industry or some other place or with some other strategy. In general, people seem to assume that: 1) although there was some degree of mystery or luck about how YC got going, it can’t be that hard, and 2) if you can get it […]
Researchers and Founders
Reading Time: 2 minutesI spent many years working with founders and now I work with researchers. Although there are always individual exceptions, on average it’s surprising to me how different the best people in these groups are (including in some qualities that I had assumed were present in great people everywhere, like very high levels of self-belief). So […]
Project Covalence
Reading Time: < 1 minuteAlmost every company and non-profit working on COVID-19 that I offered to help asked for support with clinical trials—for companies focusing on developing novel drugs, vaccines, and diagnostics, rapidly spinning up trials is one of their biggest bottlenecks. Science remains the only way out of the COVID-19 crisis. Dramatically improving clinical trials, which are usually […]
Idea Generation
Reading Time: 3 minutesThe 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. Having ideas is among the most important qualities for a startup founder to have—you will need to […]
Please Fund More Science
Reading Time: 2 minutesExperts on the COVID-19 pandemic seem to think there are three ways out—that is, for life, health, and the economy to return roughly to normal. Either we get a vaccine good enough that R0 for the world goes below 1, a good enough treatment that people no longer need to be afraid, or we develop […]
Funding for COVID-19 Projects
Reading Time: < 1 minuteI’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. I think we will soon have enough testing capacity, so now I’d like to start funding more startups working on: Producing a lot of ventilators or masks/gowns very quickly. This will require a […]
The Virus
Reading Time: < 1 minuteAlthough I still hope things will go differently, the experts I’ve spoken to think we are likely to face a global tragedy—hundreds of thousands of deaths from Covid-19. I hope that society views this as a warning for the future. Covid-19 is bad, but only a warm-up. I think it’s unlikely that this is the […]
