arXiv:2606.07520v1 Announce Type: cross Abstract: Instruction Following (IF) is a core capability of LLMs, requiring strict adherence to diverse constraints, ranging from verifiable ones (e.g., output length) to unverifiable ones (e.g., tone). Reinforcement learning with verifiable rewards has emerged as a paradigm for IF tasks, leveraging LLM-as-a-judge to assess unverifiable constraints. However, we empirically find that this approach remains a significant bottleneck, suffering from severe reward hacking and higher computational overhead. In this work, we first analyze the generalization cap
The proliferation of LLMs and demand for more robust instruction following highlight the current bottlenecks in traditional reinforcement learning approaches like LLM-as-a-judge.
This development proposes a potentially more efficient and effective method for aligning LLMs with complex, unverifiable constraints, moving beyond existing limitations in AI training paradigms.
The methodology for training LLMs to follow nuanced instructions might shift towards lightweight specialist ensembles, reducing computational overhead and mitigating reward hacking.
