OpenAI trains Neon materials model on 1,300 H200s, beating GPT-6 Astra on its own benchmark
Liam Fedus says OpenAI built high-throughput materials labs in Menlo Park and mid-trained and RL'd an open-source model called Neon on experimental data, surpassing GPT-6 Astra on its analysis benchmark.
We built high-throughput materials labs in Menlo Park to create a loop between experiments and models. The labs generate fresh data, the models learn from it, and then help us decide what to try next. Using only 1,300 H200s, plus months of our experimental data, we mid-trained and RL’d an open-source model to surpass GPT-6 Astra on our analysis benchmark. We call it Neon. This is real footage from our lab. We’re focusing first on hard problems in materials science, including superconductors, magnets, and semiconductor materials. Read our blog posts below.
