arXiv:2605.18721v2 Announce Type: replace Abstract: Post-training has split large language model (LLM) alignment into two largely disconnected tracks. Online reinforcement learning (RL) with verifiable rewards drives emergent reasoning on math and code but depends on a programmatic verifier that cannot reach open-ended tasks, while preference optimization handles open-ended generation yet forgoes the continuous exploration that powers online RL. Closing this gap requires a verifier for open-ended quality, but a scalar reward model is the wrong shape for the job. Quality is multi-dimensional, a
The rapid advancement of large language models necessitates improved alignment techniques as current methods for training open-ended tasks are showing limitations.
This development addresses a critical challenge in AI alignment, potentially unlocking more sophisticated and reliable AI agents for complex, open-ended applications.
The proposed 'General Preference Reinforcement Learning' aims to bridge the gap between verifiable online RL and preference optimization, enabling continuous exploration for open-ended AI tasks.
