Researchers have developed RELAY, a novel method for rubric-based reinforcement learning that improves upon existing GRPO techniques. RELAY employs selective self-distillation with an adaptive hand-off mechanism, allowing a frozen teacher model to guide the learning process until a plateau is detected. This approach effectively captures the detailed feedback from rubrics, which traditional methods often lose by collapsing criteria into a single reward. In evaluations across four different settings, RELAY consistently outperformed GRPO, demonstrating significant gains in performance, particularly when using Qwen3 models. AI
