Unverified claim circulating on X: Periodic Labs used 1,300 H200 GPUs plus months of its own experimental lab data to train and RL an open-weight model that reportedly beats GPT-6 Astra on its internal benchmarks. If true, it's another data-point for the "proprietary experiment data + modest compute + RL" approach challenging frontier labs.
