It is very nice to see Codex getting so much love. We are launching a $100 ChatGPT Pro tier by very popular demand.

Alzheimer’s is one of medicine's hardest unsolved problems, and one of the most devastating. At the OpenAI Foundation, we believe AI is well suited to its complexity. We're directing over $100M to scientists mapping the disease, designing drugs, & more. I wrote about it here:

To celebrate 3 million weekly codex users, we are resetting usage limits. We will do this every million users up to 10 million. Happy building!

Proud to have been part of this. We outline policy ideas for the transition to superintelligence, to build an open economy where everyone benefits and a society that is resilient to the risks. Progress is fast, and we must navigate these issues urgently.

TBPN has been acquired by OpenAI! The show is staying the same and we’ll continue to go live at 11am pacific every weekday. This is a full circle moment for me as I’ve worked with @sama for well over a decade. He funded my first company in 2013. Then helped us fix a serious

TBPN is my favorite tech show. We want them to keep that going and for them to do what they do so well. I don't expect them to go any easier on us, am sure I'll do my part to help enable that with occasional stupid decisions.

This is a very good post:

The first steel beams went up this week at our Michigan Stargate site with Oracle and Related Digital

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,

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. https://t.co/xHEj9Rf8qT

I would like a single word for this phrase: "throw it into the maw with every bit of context I can think of".

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

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

I have so much gratitude to people who wrote extremely complex software character-by-character. It already feels difficult to remember how much effort it really took. Thank you for getting us to this point.

It is also very smart, but...I generally agree with this, and really feel it myself on the 5.3 -> 5.4 upgrade.

Great first week for 5.4 in the API. Builders building fast.

32× efficiency improvement in just the last 3 months, that’s the crazy jump from GPT-5.2 to GPT-5.4! 37 cents/task is essentially almost at human-level efficiency (target was 24 cents/task). This was inconceivable a year ago when o3 cost $4500/task on ARC-AGI-1, 12,000x improved!

Hello subagents in codex. Have seen some awesome new and creative workflows emerge from these https://t.co/kw1ua4QjMh
