# Learning Beyond What You Sample: Off-Policy-Aware Cross-Model Trajectory Exchange for RLVR > Source: > Published: 2026-09-30 02:30:01+00:00 Reinforcement Learning with Verifiable Rewards (RLVR) methods such as GRPO rely on successful self-generated trajectories, but finite rollout budgets can produce all-fail groups with no reward-based policy-gradient signal. While additional rollouts improve the chance of success at higher cost, succe
