This weekend in SF: the HUD × YC Frontier RL Environments Hackathon

Haoguang and I will be there both days (Sat + Sun, 6/20–21).

RL envs are how we teach models to reach the future — and fast rollouts are how the loop actually runs. That's what we build with SGLang @ RadixArk.

We're hiring. Come say hi!
