FlowBalance: Verifier-Grounded Self-Improvement from On-Policy Reasoning Experience
TL;DR
FlowBalance is a new self-improvement method for reasoning models that enhances performance by using verifier-grounded guidance. It improves average performance on mathematical reasoning tasks while increasing training speed and stability.
✦ Why It Matters
Implement FlowBalance to enhance your reasoning models' performance and training efficiency today.
Key Takeaways
- Adopt FlowBalance for improved reasoning model performance.
- Utilize verifier-derived group advantage for better guidance.
- Monitor training speed and stability improvements.
- Encourage diversity in strategies to enhance model robustness.
How It Works
FlowBalance operates by aggregating token-level log-probability gains from a frozen view of the same policy during training. It produces a self-guidance score for each trajectory, which is then calibrated using a verifier-derived group advantage.
This allows the model to retain guidance on successful trajectories, reverse it on unsuccessful ones, and disable it when no clear preference is indicated.
