    For most of history, expertise was scarce, constrained by time and reach: one person, one career, one lifetime. Now, for the first time, we can encode, evaluate, and scale it. We believe the wisdom that once took a lifetime to build shouldn’t take a lifetime to find. Today,

    How we achieved a net win-loss margin of +21.4% on GDPval with on-policy distillation
    AfterQuery researchers trained NVIDIA’s Nemotron-3-Nano-30B-A3B with on-policy reverse-KL distillation from a frozen Nemotron-3-Super-120B-A12B teacher, using Tinker from Thinking Machines Lab. We...

    AfterQuery post-trained GPT-OSS-20B using Harbor + Tinker and saw a 14% bump on TB2 performance. Love seeing people pick up Harbor for more than just evals.

    Our findings show that current models lack the ability to perform even the most basic tasks in high-impact, real-world domains like quantitative trading. We hope Market-Bench can serve as a shared framework to evaluate models’ understanding of trading strategies and code
