OpenForgeRL is an open-source framework that allows researchers to train harness-based AI agents end-to-end using standard reinforcement learning stacks. It decouples training from inference by employing a lightweight proxy to record model calls as data and a Kubernetes orchestrator to manage rollouts in remote containers.

  • The system supports diverse environments, including tool/claw-based agents and multimodal GUI browser agents.
  • OpenForgeClaw achieves 31.7 pass^3 on ClawEval and 33.7 on QwenClawBench using only hundreds to a few thousand tasks.
  • OpenForgeGUI reaches 37.7 on OSWorld-Verified, 63.0 on Online-Mind2Web, and 72.3 on WebVoyager.
  • Both variants outperform open baselines of similar size and match or surpass larger models in GUI settings.
  • Analysis reveals that harness choice significantly impacts learning difficulty and that RL improves reliability metrics like self-verification.

The framework enables the study and improvement of agents directly within their deployment environments, demonstrating that reinforcement learning enhances agentic reliability despite remaining weaknesses in error recovery.
