jason rugolo had been hoping we would invest in or acquire his company iyo and was quite persistent in his efforts. we passed and were clear along the way. now he is suing openai over the name. this is silly, disappointing and wrong.
Extraordinarily exciting to see an LLM win IMO gold. Entering a new phase in AI! Congrats to the team delivering these results.
Their bet allowed for formal math AI systems (like AlphaProof). In 2022, almost nobody thought an LLM could be IMO gold level by 2025.
1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
ChatGPT can now do work for you using its own computer. Introducing ChatGPT agent—a unified agentic system combining Operator’s action-taking remote browser, deep research’s web synthesis, and ChatGPT’s conversational strengths.
This is exactly my top list based on my extensive vibe testing of these models. o3-pro is still the undisputed king for me, though Gemini 2.5 Pro is a close second. Based on some of the Grok 4 heavy outputs, I think it may rank above o3 and could even be in second place.
I buy this. Best time to build in decades.
The gap between what AI can do vs what we're building with it is MASSIVE right now. That gap is your opportunity to build. This might be the best time ever to start an AI company.
I am inspired by the San Franciscans coming together to support a member of our community and a critical local institution. The targeted hate speech and damage done to Manny’s is unacceptable. Monday’s protest was largely peaceful, but one instance of antisemitism is one too…
also, here is one part that people not interested in the rest of the post might still be interested in:
recently the NYT asked a court to force us to not delete any user chats. we think this was an inappropriate request that sets a bad precedent. we are appealing the decision. we will fight any demand that compromises our users' privacy; this is a core principle.
💥 Super excited about today's launches: * Deep Research can now search across @github, @googledocs, @gmail, @googlecalendar, @SharePoint, @Outlook, @HubSpot, @Dropbox, @Box, and more. * You can connect any chat to @googledocs, @SharePoint, @Dropbox, and @Box * An initial…
Such an important point and so tricky to get our heads around.
Zero sum thinking can still be a huge challenge in imagining the future of what AI will do for work. It’s critical to consider that there isn’t a fixed number of things that the world needs. AI will bring down the costs of doing certain work massively, but we will eventually…
This seems terrible.

I've been driving the research for our collab with Jony Ive from w/in OpenAI for the last year, alongside the best team imaginable. Want to join us? Search for "future of computing" here openai.com/careers/search/! PS: cover letters help me filter a ton :) nytimes.com/2025/05/21/tec…
We need to improve our global competitiveness, and special economic zones would be an accelerant across the board. Reducing taxes and regulation could help us re-shore manufacturing and move faster in key areas including robotics, drones, defense and AI.
Finally! Very excited for this.

I’m so delighted to help welcome the great @fidjissimo to @OpenAI. We couldn’t be luckier to have her deep experience and warm leadership style. Welcome, Fidji!!!
She’s all signal. No noise. Highest integrity leader I know. Very good news: for OpenAI, for all of us.
So excited to be joining @openai and contributing to its mission. Thank you @sama for the opportunity- it will be such a privilege to work with such a talented team on one of the most important and ambitious endeavors in history. I’ll remain CEO of @Instacart for the next few…
