Cowork-Gym constructs executable work environments, validates and repairs them through a build–execute–revise loop, and collects trajectories with a stateful user simulator. The resulting environments support supervised fine-tuning, reinforcement learning, and on-policy distillation.

Cowork-Gym 构建可执行的工作环境，通过构建、执行与修订闭环进行验证和修复，并借助有状态用户模拟器采集交互轨迹，支持监督微调、强化学习与在线策略蒸馏。
