Our co-founders @LiamFedus and @ekindogus sat down with @mariogabriele to discuss @periodiclabs, the limits of pure digital AI, and creating autonomous labs where nature is the RL environment.
We’ve spent the past year building high-throughput labs and infrastructure for large-scale physics experiments in our search for better superconductors and magnets. We ran our first experiments by hand. Now, experiments run continuously in the labs. We’re building AI to make sense of what they produce and to determine which experiments to run next.
Our co-CEO @ekindogus will be speaking at @RaiseSummit tomorrow. Join us at the Master Stage at 3:00 PM to hear more about the work we’re doing at Periodic.
