Sam and I are shocked and saddened by what the board did today. Let us first say thank you to all the incredible people who we have worked with at OpenAI, our customers, our investors, and all of those who have been reaching out. We too are still trying to figure out exactly what happened. Here is what we know: - Last night, Sam got a text from Ilya asking to talk at noon Friday. Sam joined a Google Meet and the whole board, except Greg, was there. Ilya told Sam he was being fired and that the news was going out very soon. - At 12:19pm, Greg got a text from Ilya asking for a quick call. At 12:23pm, Ilya sent a Google Meet link. Greg was told that he was being removed from the board (but was vital to the company and would retain his role) and that Sam had been fired. Around the same time, OpenAI published a blog post. - As far as we know, the management team was made aware of this shortly after, other than Mira who found out the night prior. The outpouring of support has been really nice; thank you, but please don’t spend any time being concerned. We will be fine. Greater things coming soon.

Thank you to President Trump for announcing Stargate Project with us today. $500B for AI data centers for OpenAI, built in the US. 🇺🇸
Announcing The Stargate Project The Stargate Project is a new company which intends to invest $500 billion over the next four years building new AI infrastructure for OpenAI in the United States. We will begin deploying $100 billion immediately. This infrastructure will secure American leadership in AI, create hundreds of thousands of American jobs, and generate massive economic benefit for the entire world. This project will not only support the re-industrialization of the United States but also provide a strategic capability to protect the national security of America and its allies. The initial equity funders in Stargate are SoftBank, OpenAI, Oracle, and MGX. SoftBank and OpenAI are the lead partners for Stargate, with SoftBank having financial responsibility and OpenAI having operational responsibility. Masayoshi Son will be the chairman. Arm, Microsoft, NVIDIA, Oracle, and OpenAI are the key initial technology partners. The buildout is currently underway, starting in Texas, and we are evaluating potential sites across the country for more campuses as we finalize definitive agreements. As part of Stargate, Oracle, NVIDIA, and OpenAI will closely collaborate to build and operate this computing system. This builds on a deep collaboration between OpenAI and NVIDIA going back to 2016 and a newer partnership between OpenAI and Oracle. This also builds on the existing OpenAI partnership with Microsoft. OpenAI will continue to increase its consumption of Azure as OpenAI continues its work with Microsoft with this additional compute to train leading models and deliver great products and services. All of us look forward to continuing to build and develop AI—and in particular AGI—for the benefit of all of humanity. We believe that this new step is critical on the path, and will enable creative people to figure out how to use AI to elevate humanity.

One of the least-appreciated skills in programming is writing anti-frustrating error messages. A good error message should make it self-evident (a) what the user did, (b) what acceptable inputs are, and (c) how to fix the problem. Can determine love or hate for your library.

OpenAI o1 — our first model trained with reinforcement learning to think hard about problems before answering. Extremely proud of the team! This is a new paradigm with vast opportunity. This is evident quantitatively (eg reasoning metrics are already a step function improved) and qualitatively (eg faithful chains of thought make models interpretable by letting you “read the model’s mind” in plain English). One way to think about this is that our models do System I thinking, while chains of thought unlock System II thinking. People have discovered a while ago that prompting the model to “think step by step” boosts performance. But training the model to do this, end to end with trial and error, is far more reliable and — as we’ve seem with games like Go or Dota — can generate extremely impressive results. It’s still early days for the o1 technology. It provides new safety opportunities which we are exploring actively, including on reliability, hallucinations, and robustness to adversarial attackers. For example, we’ve seen great uplift in our safety metrics by letting the model reason about policies via chain of thought. Its accuracy also has huge room for further improvement— for example, from our launch post, our model achieved 49th percentile / 213 points in this year’s competitive programming Olympiad (IOI) under human conditions of 50 submissions per problem. But with 10,000 submissions per problem, the model achieved a score of 362.14 — above the gold medal threshold. So the model is capable of even greater outputs than it appears at first glance.
We're releasing a preview of OpenAI o1—a new series of AI models designed to spend more time thinking before they respond. These models can reason through complex tasks and solve harder problems than previous models in science, coding, and math. openai.com/index/introducing…

A reason we need beneficial AGI: After five years of pain across many systems in her body (a broken foot from stepping off a curb, debilitating migraines, fatigue, joint pain and instability, etc), my wife was recently diagnosed with a genetic disorder called Hypermobile Ehlers-Danlos Syndrome (hEDS). Because the medical system is designed for individual specialties while hEDS affects every system in her body (orthopedics, cardiology, neurology, gastroenterology, dermatology, etc), we spent five years seeing more doctors and specialists than in her whole life prior. Most doctors would only focus on what was relevant to their own specialty. We were lucky that her allergist (!!) put together the pieces after observing and hearing her full set of symptoms and issues. As human medicine has progressed, it seems like we increase doctors’ depth at the expense of breadth. We need better tools to be able to deliver depth and breadth simultaneously to patients. This is one promise of AGI if built right — reliable, individualized, affordable healthcare in your pocket, like a panel of today’s top doctors across every speciality working together in concert to keep you healthy (and without you needing to fax forms between them). There’s still a long way to go on the technology and on learning how to deploy it beneficially along with appropriate professional human oversight in high-stakes areas like medicine, but the promise is getting increasingly clear. Thoughtfully approached by technology developers, healthcare providers, governments, and society, there’s hope for much better care for every member of all of our families (including our non-human furry ones).

Next-step prediction is beautiful because it encourages, as a model gets extremely good, learning the underlying process that produced that data. That is, if a model can predict what comes next super well, it must be close to having discovered the "underlying truth" of its data.

I have immense gratitude to Ilya for being my co-founder, my friend, and the officiant at my civil ceremony. Together, we charted the path of what OpenAI would become today. When we started in late 2015, OpenAI was a non-profit with a mission to make AGI go well but without a credible plan of how to accomplish it. In the early days, Ilya and I spent countless hours thinking hard about every aspect of culture, technical direction, and strategy. Together we realized that we would need to raise a lot more capital than anyone had imagined in order to build supercomputers of unprecedented size. We fundraised together in the non-profit, raising more than others thought possible but still far less than what was needed. We proposed creating a for-profit structure in service of the mission. And once that had been created, we continued to align and shape what that company stood for, maintaining the focus on our AGI mission while grappling with the hard practical questions of how to make progress each day. Ilya is an artist. His vision and gusto are infectious, and he helped me understand this field when I was just getting started. He is unafraid of thinking through the logical conclusion of his intuitions. We were motivated by the 1962 book Profiles of the Future, which opens with descriptions of the incorrect mindsets that led to scientific claims of the impossibility of the lightbulb, flight, and reaching orbit shortly before these feats were accomplished. So despite people doubting that AGI was anywhere on the foreseeable horizon, we would think through and act on the conviction of our beliefs that deep learning can take us there. The mission is far from complete, and Ilya played a key role in helping build the foundations of what OpenAI has become today. Thank you for everything.

Yesterday, my wife and I laid to rest our cat son, Darth. Our hearts are hurting. We will always miss and love him. Two years ago, he was diagnosed with osteosarcoma in his front leg. We had his limb removed, and he thrived as a hopping tripod. A year later, in his annual chest x-ray, we were shocked to learn his cancer had metastasized and that he had 4-6 weeks. We vowed to make every day he had left as peaceful and loving as possible. Out of sheer force of will and love, Darth fought his very aggressive cancer without medical intervention to give his family a whole extra year with him. His illness won't define him. His mom and I will always remember him for his incredible sweetness, his hilarious hiding abilities while reappearing only for his favorite humans, and his love for his yellow catnip bananas, grandma's lettuce, high places, cheek massages, and for always being nearby. We are grateful to be his parents.

Today OpenAI announced o3, its next-gen reasoning model. We've worked with OpenAI to test it on ARC-AGI, and we believe it represents a significant breakthrough in getting AI to adapt to novel tasks. It scores 75.7% on the semi-private eval in low-compute mode (for $20 per task in compute ) and 87.5% in high-compute mode (thousands of $ per task). It's very expensive, but it's not just brute -- these capabilities are new territory and they demand serious scientific attention.

Big takeaway from the GPT paradigm is that the world of text is a far more complete description of the human experience than almost anyone anticipated.

We’re really grateful to Jan for everything he's done for OpenAI, and we know he'll continue to contribute to the mission from outside. In light of the questions his departure has raised, we wanted to explain a bit about how we think about our overall strategy. First, we have raised awareness of the risks and opportunities of AGI so that the world can better prepare for it. We've repeatedly demonstrated the incredible possibilities from scaling up deep learning and analyzed their implications; called for international governance of AGI before such calls were popular; and helped pioneer the science of assessing AI systems for catastrophic risks. Second, we have been putting in place the foundations needed for safe deployment of increasingly capable systems. Figuring out how to make a new technology safe for the first time isn't easy. For example, our teams did a great deal of work to bring GPT-4 to the world in a safe way, and since then have continuously improved model behavior and abuse monitoring in response to lessons learned from deployment. Third, the future is going to be harder than the past. We need to keep elevating our safety work to match the stakes of each new model. We adopted our Preparedness Framework last year to help systematize how we do this. This seems like as good of a time as any to talk about how we view the future. As models continue to become much more capable, we expect they'll start being integrated with the world more deeply. Users will increasingly interact with systems — composed of many multimodal models plus tools — which can take actions on their behalf, rather than talking to a single model with just text inputs and outputs. We think such systems will be incredibly beneficial and helpful to people, and it'll be possible to deliver them safely, but it's going to take an enormous amount of foundational work. This includes thoughtfulness around what they're connected to as they train, solutions to hard problems such as scalable oversight, and other new kinds of safety work. As we build in this direction, we're not sure yet when we’ll reach our safety bar for releases, and it’s ok if that pushes out release timelines. We know we can't imagine every possible future scenario. So we need to have a very tight feedback loop, rigorous testing, careful consideration at every step, world-class security, and harmony of safety and capabilities. We will keep doing safety research targeting different timescales. We are also continuing to collaborate with governments and many stakeholders on safety. There's no proven playbook for how to navigate the path to AGI. We think that empirical understanding can help inform the way forward. We believe both in delivering on the tremendous upside and working to mitigate the serious risks; we take our role here very seriously and carefully weigh feedback on our actions. — Sam and Greg
i'm super appreciative of @janleike's contributions to openai's alignment research and safety culture, and very sad to see him leave. he's right we have a lot more to do; we are committed to doing it. i'll have a longer post in the next couple of days. 🧡

People often ask if ML or software skills are more the bottleneck to AI progress. It’s the wrong question—both are invaluable, and people with both sets of skills can have outsized impact. We find it easier, however, to teach people ML skills as needed than software engineering.
coming up with good ml research ideas is significantly easier than implementing them in a complex codebase — the returns to being an extremely good engineer are super high
