VibeTraining-Bench: Data-Trainer-Harness Co-Design for Iterative System Improvement

We introduce VibeTraining-Bench, a benchmark for evaluating this capability across tasks spanning terminal operation, software engineering, multi-turn tool use, and mathematical reasoning.

Key points

  • Recursive self-improvement (RSI) requires agents to diagnose system bottlenecks and coordinate improvements across training and inference.
  • We refer to the agents' capability to jointly optimize training data, the trainer, and the inference harness as cross-component co-design.
  • Our evaluation results show that frontier research agents substantially improve target agent systems.
  • We hope that VibeTraining-Bench will serve as a unified platform for advancing RSI, deepening our understanding of cross-component optimization for agent systems.
