arXiv:2605.27701v1 Announce Type: new Abstract: We present Frost Training, a method for improving Monte Carlo-based policy optimization for a large family of LLM-as-a-judge tasks called Cross-Entropy Games. The key idea is to exploit the gradient of the reward function in embedding space. This signal is used in the Greedy Coordinate Gradient (GCG) jailbreaking technique; we demonstrate for the first time that it can also be used to boost model training. We validate our method using GRPO training for maximum-likelihood infilling. Frost Training improves the model's ability to generate high-scor
The continuous advancements in LLM technology and the increasing need for robust policy optimization drive the development of more sophisticated training methods.
This development suggests a significant improvement in the efficiency and capability of LLM training, potentially leading to more advanced and reliable AI models.
The ability to exploit reward function gradients in embedding space for model training introduces a new paradigm for optimizing LLMs, moving beyond traditional Monte Carlo methods.
