Periodic Labs' Neon beats GPT-6 Astra on materials benchmark with just 1,300 H200s
LiamFedus · x · 2026-09-16
Liam Fedus (ex-OpenAI VP of Research) unveiled Neon from Periodic Labs: an experiment-model closed loop for materials science.
- The team built high-throughput materials labs in Menlo Park: labs generate fresh data, models learn from it, then decide what to try next
- Using only 1,300 H200s plus months of experimental data, they mid-trained and RL'd an open-source model to surpass GPT-6 Astra on their analysis benchmark
- First targets: superconductors, magnets, and semiconductor materials; blog posts are live
