Virtually nobody is pricing in what's coming in AI. I wrote an essay series on the AGI strategic picture: from the trendlines in deep learning and counting the OOMs, to the international situation and The Project. SITUATIONAL AWARENESS: The Decade Ahead

As part of today, we’re also releasing o1-mini. This is an incredibly smart, small model that can also reason before it’s answer. o1-mini allows us at OpenAI to make high-intelligence widely accessible. openai.com/index/openai-o… On the AIME benchmark, o1-mini re-defines the

Terence Tao’s grading: GPT-4o: Completely incompetent graduate student o1-preview: Mediocre but not completely incompetent graduate student A step change.

i love being home in the midwest. the night sky is so beautiful. excited for the winter constellations to rise soon; they are so great.

it's a good model sir

No more waiting. o1's is officially on Chatbot Arena! We tested o1-preview and mini with 6K+ community votes. 🥇o1-preview: #1 across the board, especially in Math, Hard Prompts, and Coding. A huge leap in technical performance! 🥈o1-mini: #1 in technical areas, #2 overall.

And we are hiring! Come work with us on pushing the frontiers of both model capability and efficiency.

While today’s departures are tough, I’m incredibly excited and honored to lead research at OpenAI alongside Jakub Pachocki. I truly believe that OpenAI is the best place to work on AI, and I've been through enough ups and downs to know it's never wise to bet against us.

Nat McAleese hey now

Excited to train o3-mini with Hongyu Ren Kevin Lu and others, a blindingly fast model with amazing reasoning / code / math performance. openai.com/12-days/?day=12

We are also hiring top researchers/engineers to keep breaking the data wall and find out ways to pretrain both frontier models & extremely cost/performance efficient models. If you are interested in working on this, apply & drop me an email.

We trained o3-mini: both more capable than o1-mini, and around 4x faster end-to-end when accounting for reasoning tokens with Hongyu Ren Shengjia Zhao & others

Today, we shared evals for an early version of the next model in our o-model reasoning series: OpenAI o3

The new AI challenge should be to come up with an eval that is actually solvable by people/gradable and survives for >1 yr.

My account was hacked. I do NOT endorse any crypto or web3 project. Thanks to everyone who helped to spot this and prevent damages. The lesson is to turn on 2FA and always have a second thought of "is this phishing" before clicking on anything :(

o3-mini is out! smart, fast model. available in ChatGPT and API. it can search the web, and it shows its thinking. available to free-tier users! click the "reason" button. with ChatGPT plus, you can select "o3-mini-high", which thinks harder and gives better answers.

Today we’re releasing a research preview of GPT-4.5—our largest and best model for chat yet. Rolling out now to all ChatGPT Pro users, followed by Plus and Team users next week, then Enterprise and Edu users the following week.

Training big models are hard and congrats to the team on the incredible work putting all of this together!

It's deeply concerning that one of the best AI researchers I've worked with, Kai, was denied a U.S. green card today. A Canadian who's lived and contributed here for 12 years now has to leave. We’re risking America’s AI leadership when we turn away talent like this.
