In April, '17, @jsomers of @NewYorker reached out & said he wanted to do a small profile of me & my longtime colleague Sanjay Ghemawat, watch us work for a few hours, maybe dinner, etc.

It came out today. I think it captures our working style really well. https://t.co/cRSMiFfwAP

Three of the four Fields Medalists announced today by the International Mathematical Union are Princeton alumni: Yu Deng *15, John Pardon '11, who is a former mathematics faculty member, and Jacob Tsimerman *11.

The medal, awarded every four years to researchers under 40 years old, is one of the most prestigious awards in mathematics. It recognizes both “outstanding mathematical achievement for existing work” and “the promise of future achievement,” the IMU said in its 2026 Fields Medal announcement.

Christopher Skinner, Princeton professor of mathematics and chair of the department, extended warm congratulations to all of the 2026 Fields Medalists. "The awarding of the Fields Medal every four years is an opportunity to celebrate some great mathematics," he said.

“But it is especially thrilling for the department to have the remarkable works of three of its alums awarded medals this year,” Skinner said. "Yu Deng *15, Jacob Tsimerman *11 and John Pardon '11 are exceptional talents, and we are delighted to see them getting this well-deserved recognition and to bask a little in the glow of their accomplishments."

Neuralink has solved through-dura electrode implantation!

This is a very big deal, as it greatly improves the safety and ease of interfacing with the brain.

Nice work by the @Tesla_AI team!

The AI3 computer only has ~15% of the effective memory bandwidth of AI4, so this was a tough challenge.

Tesla FSD v14 Lite is rolling out to customers with our AI3 hardware

[Ashok Elluswamy @aelluswamy]

FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.

This build distills the driving behavior from AI4’s v14 series into both the camera and compute config of AI3. It includes destination options and speed profiles on city roads, but more importantly significantly improved safety.

We hope you’ll enjoy it, once the build ships wide.
