Last weekend 200+ of the best builders showed up to our Frontier RL Environments Hackathon at
@ycombinator.
The idea behind HUD is simple: anything you can simulate and grade, you can improve with RL.
Teams built RL envs for autonomous farming, gene editing, city planning, world sims, and games. Some did autonomous ML research + chip design, and used HUD to RL their own open models past Opus 4.8 in-domain.
Huge thanks to our cosponsors for making it happen!
If you want to work on RL, or just be at the frontier of AI, build with us, we're hiring:
