Today, I’m excited to formally announce @mirendil with my amazing co-founders Harsh Mehta, Shayan Salehian, and Tara Rezaei! We’re fortunate to work with @a16z and @kleinerperkins, who led our seed round of $200M, followed by a major investment from NVIDIA, among others. Mirendil exists to accelerate science and technology, and through them, to help solve humanity's most pressing problems. Self-accelerating AI R&D is the most direct path to delivering on AI's broader promise, which is why we believe the most important application of AI is AI itself. Get this loop right, and it compounds. It fundamentally changes the rate of progress itself across all domains. We believe this capability should be democratized. It should be used to power all scientific efforts trying to innovate at the frontier. There are far more important problems—and broader ones—than any single lab can take on, so more groups should be able to pursue them. This pulls concentration of power away from a few labs: businesses and science labs can own their AI and infrastructure, keep their margins, and control their own destiny instead of ceding it all to a single AI lab. We’re a small team with a singular focus. Our founding team consists of 20 researchers and engineers from frontier institutions including Anthropic, xAI, Google DeepMind, and OpenAI, united by a passion for science and a drive to build the technologies that move it faster. If you want to build the system that builds systems, join us! @HarshMeh1a, @shayan_, @tararezaeikh

Today, we're announcing a multi-year partnership with @Google to power the next generation of self-accelerating AI! Mirendil will scale its training, inference, and AI research workloads on @googlecloud 's AI Hypercomputer — drawing on both TPUs and full-stack NVIDIA AI Infra.

Last week, we celebrated @mirendil's launch alongside some of the researchers, engineers, and friends who helped us get here. It was energizing to bring together so many people who share our belief that science can, and should, move faster. Democratizing frontier AI is the most direct path to realizing that potential.

This marks the beginning of a significant phase transition in the behavior of frontier AI labs and their relationship with the rest of the world 🧵

mythos will be bad ON PURPOSE on ai "frontier llm research" tasks, this is very very sad for the research community also the fact that this is un purpose not visible to the user is crazy

Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor. It’s happening faster than we thought, and the implications deserve greater attention. anthropic.com/institute/recu…

academics are unprepared for the coming world where much scientific progress is majorly a function of inference compute. whether OpenAI points the Eye of Stargate at your particular field will decide its acceleration. talent will leach away into the labs. it's already begun

We are looking for someone with high agency and product vision to help shape our first product from the ground up! If you are excited about Mirendil’s vision (checkout our website), please apply/reach out. Referrals welcome. I would also love to hear what you think we should build toward!

We have been heads down but wanted to share a bit about what we are doing 🧵

Career update: I left xAI to start something new, closing my 7+ year chapter working at Twitter, X, and xAI with so much gratitude. xAI is truly an extraordinary place. The team is incredibly hardcore and talented, shipping at a pace that shouldn’t be possible. From the Home Timeline at X to Grok 2, 3, and 4 at xAI, I worked across product infra and model behavior post-training, from memory to coding infra, agents, and more. Pure startup mode, every day. Working closely with Elon across X and xAI, I saw what happens when you refuse to accept impossible as an answer. I learned to embody obsessive attention to detail, maniacal urgency, and to think from first principles. I’m deeply grateful to @elonmusk for the experience, to @wanghaofei for the trust and support throughout Twitter/X, and to @TheGregYang and @ibab for believing in me. And to the many incredible people I had the privilege to work with along the way, thank you! Now, I’m excited to take the leap and build something new, focused on accelerating science. More soon.

Career Update: I've left Anthropic to start something new. Anthropic is a magical place — amazing people, strong culture, and unmatched taste. I have a lot of respect for my friends and ex-colleagues, and knowing them, I'm confident they'll do the right thing, especially when the choices are hard. I feel grateful and proud to have been part of the journey with them. Excited to start a new chapter — stay tuned for more!

$40,000 grand prize winner announced! We loved organizing the Inference Time Compute Hackathon this weekend with @mercor & @Etched! Powered by pizza, @AnthropicAI, & @CoreWeave, hackers had 24 hours to build and train. Winners & what they built 🧵👇
