My longest agent run last week was 11 hours. It finished its list before I woke up.

I recently had some fun with a kernel optimization competition as part of the MOA Workshop at MICRO 2026. I was curious how well frontier models can write kernels for an accelerator they have never seen.
On CUDA they are strong. On an accelerator whose architecture and programming language they have rarely seen, their accuracy collapses. So I built an agent loop that learns the chip first, then generates and tunes kernels on it. It turned into a paper. With no prior knowledge of the target, the loop still reached about a 9x geomean speedup over the official baseline.

Help put gigawatts of AI infrastructure on a production line.
Fluidstack is building toward tens of gigawatts of compute. On our Modular team, you’ll design electrical systems built in a factory and connected on site.

Not my news, but I couldn't be prouder of my father, Prof. Jangsoo Chun.
After decades of osteoarthritis research, he has published in Cell, Nature, and Science. "A CNS grand slam", one of very few in Korean life sciences. One question, pursued for decades.
The new paper shows that high blood pressure fuels osteoarthritis through neuroendocrine signaling.
Congrats to co-corresponding author Prof. Je-Hwang Ryu and the team. 🎉

America coming back to making things was definitely not in the cards but WE ARE SO BACK
HISTORIC: We just approved the first-ever U.S. commercial small modular reactor construction permit, completed ahead of schedule in just 14 months, through efficient, safety-focused review. The future of advanced nuclear starts now. nrc.gov/about-nrc/news-relea… #NRCNews

We’ve begun construction on the $4 billion first phase of our Cameron County, Texas Data Center Campus, planned to support up to 1.5 GW of capacity. The project is expected to create more than 2,500 construction jobs and several hundred permanent positions.
We’re growing our team and looking for talent across the Valley to help build this best-in-class campus. Learn more: fluidstack.io/community/buil…

I'm proud of the work we're doing on behalf of communities in my home state.
Power and water are real concerns, but data centers and AI infrastructure providers work with local communities to ensure that the rising tide lifts all boats, providing local jobs, improved infrastructure, and lower bills, all without taking water from aquifers or municipal lines.
Together, we're building the frontier.
Together with @CipherInc and @AnthropicAI, Fluidstack is committing $10 million to improve Colorado City’s water infrastructure and help residents count on a more reliable water supply. We’re proud to fund additional water storage, replacement of aging valves and other improvements identified by city leaders.
We’re investing in the community that hosts our Barber Lake campus. Barber Lake draws no municipal water. This funding will directly benefit residents and help strengthen the water system they depend on.
