After 11 years building PyTorch Lightning and Lightning AI, I'm stepping down as CEO.

What started as a research library I built for myself became something far bigger than I ever imagined. I'm incredibly proud of the team, what we've built together, and where Lightning is headed next.

The company is in great hands, and I'm excited to get back to what I love: building things from scratch.

The yak is shaved. Time to build ⚡️

oddbits.ai The Yak is Shaved After 11 years, from PyTorch Lightning to a $2.5B AI cloud, I’m leaving Lightning AI. The yak is shaved. Now it’s time to build what's next.

Jensen has been one of the most influential people in my journey as a founder, and a CEO I’ve always looked up to. Few people have done as much to advance AI and make it accessible to the world.

His support for me, the AI community, Lightning AI, and open source has meant more than he probably knows.

I'll always be grateful. Thank you, Jensen.

i was diagnosed with thyroid cancer many years ago purely by chance, because i had to get blood work for my US green card application (thank you, USCIS!). i was in my mid-30’s and was reasonably healthy (or so i believed.) this was shocking and totally unpredictable news to me. thanks to the amazing team of clinicians at NYU Langone, i successfully went through a total thyroidectomy followed by radioactive iodine therapy. but, it was truly the most uncertain and confusing period of my life.

this is when i first realized that no one can opt out of healthcare. being sick isn’t what you choose to or choose not to. it is something that unpredictably happens to all of us at some point for one reason or another. this is why it is a healthcare system that we collectively build and use to support each other at the society level. because it must support everyone, the complexity of creating, maintaining and improving this system is a Herculean effort that calls for all the help in the world.

today, i am announcing @OrtetAI together with my dear co-founders, @keunwoochoi, @HenriDwyer, @elmanmansimov, @causalclaudia and Jeff, to lend our support to improving the health of each and every one of us. Ortet’s goal is to create a technological foundation that will enable health systems to deliver predictably better care to each and every patient. this will only be possible by working closely with all stakeholders in the broader ecosystem, which is enabled in part by Ortet’s close partnership with Thoreau.

Ortet is taking the very first step of a long journey ahead, and at the end of this journey, i strongly believe we would be able to say that Ortet had contributed to building better, more predictable healthcare and thus to improving health of each and every one of us.

congrats! ⚡️
Ortet @OrtetAI Sep 29
We’re excited to announce Ortet, a frontier AI lab for health.

A fundamental gap in care today is that the industry and its scientific tools focus on discovering what works at the population level, while it is individual patients we must focus on to deliver the best care. Individualized care requires a broad view of the patient, the care they receive, and the system around them. Yet the information needed for such a view remains fragmented.

At Ortet, our goal is to create continuously improving intelligence for every patient: the Ortet Health Model, bringing together biological, clinical, and operational dimensions to better predict what happens next and which actions are most likely to lead to better outcomes. To deliver it, we are creating frontier AI from the ground up—across compute, data infrastructure, and models—and building and operating at every layer of AI.

We are scientists and engineers behind foundational AI advances, including the attention mechanism, GRU, and neural text-to-image generation. Across the team, our work spans frontier AI research, health, life sciences, and large-scale data and compute infrastructure—from building AI for lab-in-the-loop molecular design and co-founding Prescient Design to establishing Genentech’s frontier research team and building the largest GPU cluster in life sciences.

We imagine a future where everyone has access to affordable, precise, and better care.

If you want to help us build that future, join us: ortet.ai
