Synthesis Superintelligence: from Semiconductors to Superconductors — Periodic Labs’ Liam Fedus and Ekin Dogus Cubuk

Periodic Labs argues scientific discovery requires AI-run physical experiments, not just scaled pretraining, positioning labs as the next AI capex frontier.

• Thesis: Periodic Labs (founded ~Sept 2024 by ex-OpenAI/Google DeepMind researchers Liam Fedus and Ekin Doğuş Çubuk) bets AI progress needs physical experiments, not just more internet data, calling its goal "synthesis superintelligence."
• Autonomous lab loop: Menlo Park labs run high-throughput synthesis, XRD characterization, and DFT simulation in a closed RL loop where every instrument is given AI control ("140 IQ") to reduce noise and latency bottlenecks.
