arXiv:2603.18363v2 Announce Type: replace Abstract: Unsupervised Reinforcement Learning from Internal Feedback (RLIF) has emerged as a promising paradigm for eliciting the latent capabilities of Large Language Models (LLMs) without external supervision. However, current methods rely on heuristic intrinsic rewards, which often lack a well-defined theoretical optimization target and are prone to degenerative biases. In this work, we introduce PowerFlow, a principled framework that reformulates unsupervised fine-tuning as a distribution matching problem. By casting GFlowNet as an amortized variat
This paper addresses critical limitations in current unsupervised reinforcement learning for LLMs, suggesting a more theoretically grounded approach to unlock their potential, pushing the boundaries of AI capabilities.
A principled framework for unsupervised fine-tuning could significantly improve the efficiency and reliability of LLM development, broadening their application and reducing reliance on costly human supervision.
The shift from heuristic intrinsic rewards to a distribution matching problem could lead to more robust, less biased, and more capable LLMs, accelerating progress in AI autonomy and agentic systems.
