arXiv:2606.05606v1 Announce Type: new Abstract: LLM post-training often relies on reinforcement learning methods that sample multiple rollouts per prompt, yet most existing approaches use a fixed rollout budget for every prompt, despite large differences in the training signal different prompts provide. In this paper, we study adaptive rollout allocation under a fixed global budget and formulate the problem as online resource allocation with prompt-level diminishing returns. Our method, CERO, maintains a Beta posterior over each prompt's success probability and uses the posterior expected Bern
The rapid development and widespread adoption of large language models (LLMs) are pushing the boundaries of efficient post-training methods, necessitating innovations for better resource allocation.
Adaptive optimization techniques like CERO can significantly enhance the efficiency and performance of LLM training, directly impacting the development pace and cost-effectiveness of advanced AI systems.
The shift from fixed to adaptive rollout budgets in RL post-training allows for more intelligent allocation of computational resources, leading to faster convergence and better model quality for specific tasks.
