Big update: the @GetContextAI team is joining @OpenAI to build the future of evals!
It's clear that evals are a key requirement to building high performing AI applications - but they’re hard to get right.
We are thrilled to be joining the incredible OpenAI team to build the tools developers need to succeed

"Hey Dario, congrats again on the great quarter. Nice to see the Enterprise re-acceleration. Hoping you could provide a little color on that 10% extinction # and some of the puts and takes that might have on further enterprise adoption. And then just a quick follow-up after"

Today, I shared with the OpenAI team that I have decided to leave my full-time role at OpenAI and transition to being a part-time advisor.
Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I’ve lived with for seven years. During that time, it became clear that the road to recovery would be much longer and more complex than I had anticipated—and that I needed to focus on it fully.
When I went on leave, many people told me I was courageous for prioritizing my health. The truth is that I am only making this decision now because I failed to make it many times before.
Over the years, doctors, friends, colleagues, and loved ones encouraged me to slow down. Two years after I got sick, Facebook offered me the opportunity to take a full year of medical leave. I didn’t even pause to consider it. I immediately said no. At the time, Zuck told me I should play the long game. I wish I had listened.
Looking back, I realize that a lot of what made me successful also made this decision incredibly difficult.
I grew up believing that opportunities were precious and that when they appeared, you grabbed them with both hands. That mindset carried me from a small town in southern France to opportunities I never could have imagined. By the time I turned 40, I had already gotten to do more than I’d ever dreamed possible as a kid growing up in Sète.
I love building. My work has always given me a deep sense of purpose. OpenAI in particular felt like a role that my entire career had been building toward, which made this decision even harder.
But what I’m learning now is that grit and endurance are not the only skills required to have impact over decades. Sometimes the harder thing is to stop, listen, and trust that taking care of yourself today makes it possible to contribute for much longer tomorrow.
This experience has also strengthened my conviction about why this work matters.
It has been a jarring experience to spend my days helping build the future while simultaneously navigating a disabling disease that still has no cure.
Over the last seven years, I’ve spent countless hours in doctors’ offices, dealing with symptoms, treatments, insurance, uncertainty, and all the invisible work that comes with being a patient. Like millions of others living with chronic illness, I’ve experienced firsthand how difficult healthcare can be to navigate, even when you have every possible advantage.
More than ever, I believe that some of the most important opportunities for AI lie in helping people solve real problems in their daily lives: their health, their finances, their time and the everyday burdens that shape human experience.
In particular, curing disease is the most important thing AI could accomplish. I’m excited to continue working towards cures through OpenAI but also through my work with @ChronicleBioAI and @CODA_research.
I’m deeply grateful to @sama, @gdb and the OpenAI board for their support during this time and for offering a way for me to continue contributing to the mission without sacrificing my chances of recovery. I’m also so thankful to my team and the many extraordinary colleagues I’ve had the privilege to build alongside.
For now, my focus is recovery. But my belief in the potential of technology to solve deeply human problems has never been stronger.

Today we're launching Intercept: a $500M philanthropic initiative to make respiratory infections, like the common cold and flu, a thing of the past.
We treat respiratory infections as a minor nuisance, but that’s really not the case. Most of us will spend 5% of our lives (!) sick from these viruses, they kill 1M people a year, cost $600B annually in productivity, and periodically threaten civilization through pandemics.
So, if they’re such a big problem, why haven’t we dealt with them yet? Last year we convened ~40 leading scientists, pharma R&D leaders, biotech investors, and regulatory experts to better understand that.
We heard two main reasons:
(1) First, it’s just technically very challenging: respiratory viruses represent hundreds of distinct, mutating strains across several families. Fortunately, recent breakthroughs make this newly possible.
(2) Second is a lack of funding: broad-spectrum solutions have historically been underfunded, in part because they’re not a great fit for most philanthropic or commercial funding (and while COVID generated a burst of activity around preventing and understanding respiratory infections through an influx of new funding, that hasn't been sustained).
We think that with enough focus and funding, this might be solvable. Intercept is a $500 million philanthropic initiative that will take advantage of new tools to catalyze the development and deployment of two types of products: broad-spectrum preventatives and air cleaning technologies.
This problem is undoubtedly difficult. But it’s more tractable now than it’s ever been. We think we should give it our best shot.
We’re enormously grateful to our anchor funders: @stripe, @AnthropicAI, @TheFluLab, @FoundationOAI and individuals from Jane Street.
And, I’m very excited to be building this with @incredutility and the rest of the team.
Hard to overstate how good Codex is with the Gong and Slack MCPs to find and analyze customer feedback

Build workspace agents for your team, on top of a cloud-hosted Codex harness. Hook them up to tools, give them recurring tasks, and talk to them from surfaces like Slack.
Easier than ever to bring the power of agents to your computer work.
Workspace agents are here!! I’m so excited to ship this
Agents use the Codex harness to complete difficult, repeated work. You create agents in ChatGPT with a conversational builder - and your agents work across the third party products you know and love

Codex hit 4M active users, less than two weeks after hitting 3M.
We will reset rate limits today!

Because I’ve seen confusion about this:
Context[.]ai is not the same company as the one that OpenAI acquired last April. We suspect the current owner, formerly known as context[.]inc, acquired the domain after that acquisition.
Here's my update to the broader community about the ongoing incident investigation. I want to give you the rundown of the situation directly.
A Vercel employee got compromised via the breach of an AI platform customer called Context.ai that he was using. The details are being fully investigated.
Through a series of maneuvers that escalated from our colleague’s compromised Vercel Google Workspace account, the attacker got further access to Vercel environments.
Vercel stores all customer environment variables fully encrypted at rest. We have numerous defense-in-depth mechanisms to protect core systems and customer data. We do have a capability however to designate environment variables as “non-sensitive”. Unfortunately, the attacker got further access through their enumeration.
We believe the attacking group to be highly sophisticated and, I strongly suspect, significantly accelerated by AI. They moved with surprising velocity and in-depth understanding of Vercel.
At the moment, we believe the number of customers with security impact to be quite limited. We’ve reached out with utmost priority to the ones we have concerns about. All of our focus right now is on investigation, communication to customers, enhancement of security measures, and sanitization of our environments. We’ve deployed extensive protection measures and monitoring. We’ve analyzed our supply chain, ensuring Next.js, Turbopack, and our many open source projects remain safe for our community.
The recommendation for all Vercel customers is to follow the Security Bulletin closely (vercel.com/kb/bulletin/verce…). My advice to everyone is to follow the best practices of security response: secret rotation, monitoring access to your Vercel environments and linked services, and ensuring the proper use of the sensitive env variables feature.
In response to this, and to aid in the improvement of all of our customers’ security postures, we’ve already rolled out new capabilities in the dashboard, including an overview page of environment variables, and a better user interface for sensitive env var creation and management. As always, I’m totally open to your feedback.
We’re working with elite cybersecurity firms, industry peers, and law enforcement. We’ve reached out to Context to assist in understanding the full scale of the incident, in an effort to protect other organizations and the broader internet. I also want to thank the Google Mandiant team for their active engagement and assistance.
It’s my mission to turn this attack into the most formidable security response imaginable. It’s always been a top priority for me. Vercel employs some of the most dedicated security researchers and security-minded engineers in the world. I commit to keeping you updated and rolling out extensive improvements and defenses so you, our customers and community, can have the peace of mind that Vercel always has your back.

If there is one good thing that can come out of having my health issues exposed to the world, it’s raising awareness for complex chronic conditions like POTS, MECFS, Long Covid or EDS. 🧵

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!

The companies that succeed in the future are going to make very heavy use of AI. People will manage teams of agents to do very complex things.
Today we are launching Frontier, a new platform to enable these companies.

I am Tibo and I have an incredible team. Codex would not exist without them and they cooked.
Enjoy the new Codex app, access through your free/go ChatGPT plan and 2X rate limits on other plans. Can't wait to hear what you do with it.
