Agentic RL is a whole new beast. Things broke. A lot.
Pods crashed. Registries choked. Runs stalled.
I spent the last few months in the trenches isolating failures and fixing bottlenecks. RL360 is what came out of it: millions of rollouts, scaled across multiple experts.
We're open-sourcing RL360, the RL infrastructure behind K2 Horizon's six domain experts: 8,192 concurrent sandboxes, 150 steps in 7 days, ~1.3M rollouts.
Long-horizon agentic RL runs thousands of agents in real sandboxes on tasks that take minutes. Some of those sandboxes crash
