The coolest meeting I had this week with was Paul, who used ChatGPT and other LLMs to create an mRNA vaccine protocol to save his dog Rosie. It is amazing story. "The chat bots empowered me as an individual to act with the power of a research institute – planning, education, troubleshooting, compliance, and yes, real scientific design work in converting genomic data to a vaccine prescription and designing the treatment protocol around it. But they worked alongside humans at every step. The combination is what made it possible." It immediately got me thinking "this should be a company". Also, Paul is an extraordinary guy. This should be easy to do, but it is not yet. Paul S. Conyngham (@paul_conyngham) x.com/i/article/203686739439… — https://nitter.net/paul_conyngham/status/2036940410363535823#m

The new OpenAI nonprofit just announced that it aims to spend $1B in its *first year" and will be led by two superb humans — @JacobTref and @woj_zaremba. Simply put, this initiative has huge potential to do a whole lot of good. bloomberg.com/news/articles/…

I would like a single word for this phrase: "throw it into the maw with every bit of context I can think of". Ethan Mollick (@emollick) GPT-5.4 Pro continues to be the only model of its class. For anything really hard & complex, I throw it into the maw with every bit of context I can think of. More often than not, something very useful comes out. I can't get the same results from Codex or Code or anything else. — https://nitter.net/emollick/status/2036136822099628173#m

AI will help discover new science, such as cures for diseases, which is perhaps the most important way to increase quality of life long-term. AI will also present new threats to society that we have to address. No company can sufficiently mitigate these on their own; we will need a society-wide response to things like novel bio threats, a massive and fast change to the economy, extremely capable models causing complex emergent effects across society, and more. These are the areas the OpenAI Foundation will initially focus on, and in my opinion are some of the most important ones for us to get right. The Foundation will spend at least $1 billion over the next year. @woj_zaremba, co-founder of OpenAI, will transition to Head of AI Resilience. I believe that shifting how the world thinks about safety to include a Resilience-style approach is critical, and I am extremely grateful to Wojciech for taking on this role. Wojciech has been my cofounder for the last decade; anyone who knows him will understand what I mean when I say he is one of a kind. He has a lot of ideas about how we build a new kind of AI safety. @JacobTref is joining as Head of Life Sciences and Curing Diseases. @annaadeola, our VP of Global Impact, will transition to Head of AI for Civil Society and Philanthropy. @robert_kaiden is joining as Chief Financial Officer. @jeffarnold is joining as Director of Operations.

I have loved being on the Helion board; I continue to be extremely excited about a future with abundant energy and Helion in particular. As Helion and OpenAI start to explore working together at significant scale, it is difficult for me to be on both boards. (I will have a financial interest in Helion so still be recused from negotiations, but from a governance perspective this will make things easier for both companies.) David and Chris are exceptional founders and I think people will be quite impressed by the company's progress. David Kirtley (@Dkirtley) Sam Altman is stepping down from Helion’s Board of Directors. This decision enables Helion and OpenAI to explore future partnerships to bring zero-carbon, safe electricity to the world, which Helion is perfectly poised to deliver. Sam has played an integral role in Helion’s development; I am extremely grateful for his commitment to Helion since he joined our board in 2015. He has pushed me and the Helion team to dream big, build with urgency, and focus on the thing that matters most: deploying fusion for our customers as quickly as possible to fully satisfy the world’s need for clean and abundant energy. Fusion would not be where it is today if it were not for Sam’s support over the last decade. Sam, thank you for your vision, your encouragement, and your commitment to Helion. I look forward to working with you in this new capacity. — https://nitter.net/Dkirtley/status/2036120194805014537#m

It is also very smart, but…I generally agree with this, and really feel it myself on the 5.3 -> 5.4 upgrade. rohit (@krishnanrohit) GPT 5.4 is very good, but its most distinguishing characteristic is its humanity. 5.3 Codex was already incredible at coding so it's interesting to see what made it so much more successful. People claim they want a 10x autist savant coder, but what they want is personality. — https://nitter.net/krishnanrohit/status/2033616786978181185#m

Great first week for 5.4 in the API. Builders building fast. Greg Brockman (@gdb) gpt-5.4 has ramped faster than any other model we've launched in the API: within a week of launch, 5T tokens per day, handling more volume than our entire API one year ago, and reaching an annualized run rate of $1B in net-new revenue. it's a good model, try it out! — https://nitter.net/gdb/status/2033605419726483963#m

Hello subagents in codex. Have seen some awesome new and creative workflows emerge from these Subagents are now available in Codex. You can accelerate your workflow by spinning up specialized agents to:
• Keep your main context window clean
• Tackle different parts of a task in parallel
• Steer individual agents as work unfolds
