Paper: Learning to Reason under Off-Policy Guidance

What they're saying

The authors explore using off-policy data (generated by another model) to guide RL training. They claim that leveraging diverse off-policy experience improves reasoning robustness and sample efficiency.

The Critique

Off-policy data may include flawed or unsafe reasoning. The study does not carefully filter the off-policy trajectories or analyse the risk of degeneracy. There is no evaluation on tasks requiring high-stake decision making.

Why It Matters

Off-policy learning could accelerate progress by reusing existing data rather than requiring expensive human feedback.

What They Missed

The authors do not compare with on-policy RL or supervised fine-tuning, making it difficult to isolate the benefits of off-policy guidance.

The Big Question

How can we ensure that off-policy guidance steers models toward better reasoning rather than just reinforcing the status quo?
