Addressing LLM Post-Training Challenges
The post-training phase for large foundation models using reinforcement learning often involves selecting training problems from vast, heterogeneous datasets. This choice critically impacts training stability, sample efficiency, and final performance. Traditional curriculum learning methods, which rely on manual annotations or tabular statistics, fail to scale to modern, continuously evolving datasets and struggle with the dynamic nature of actor updates. ACTOR-CURATOR directly addresses these limitations.
ACTOR-CURATOR: A Co-adaptive Framework
ACTOR-CURATOR is a scalable, fully automated framework for RL post-training of LLMs. At its core is a neural curator that dynamically selects problems from large problem banks, aiming to maximize expected policy performance improvement. Problem selection is formalized as a non-stationary stochastic bandit problem, with a principled loss function derived from online stochastic mirror descent and regret guarantees under partial feedback. This approach, enhanced with function approximation and PPO-style clipping, allows for robust generalization and stability.
Unprecedented Performance Gains
Empirically, ACTOR-CURATOR consistently outperforms uniform sampling and strong learning-based baselines across a wide range of challenging reasoning benchmarks, including Countdown, Zebra, MATH, AIME, and ARC-1D. It demonstrates improved training stability, efficiency, and achieves significant relative gains (up to 30.5% on ARC-1D, 28.6% on AIME24) and substantial speedups (up to 80%). These results validate ACTOR-CURATOR as a practical and principled solution for scalable, adaptive curriculum learning.

Real-world Impact: Accelerating LLM Reasoning in Production
ACTOR-CURATOR shifts the paradigm of LLM post-training by transforming data selection from a static resource into a dynamic, optimizable component of the learning process. This approach is particularly critical for enterprises dealing with continuously evolving datasets and complex reasoning tasks. By intelligently curating problems that yield the greatest policy improvement, ACTOR-CURATOR ensures that LLMs train more efficiently and achieve higher final performance. This leads to faster deployment cycles, reduced computational costs, and more robust, adaptable AI systems in real-world applications such as advanced analytics, automated code generation, and complex problem-solving. It minimizes reliance on meticulous dataset engineering, making pipelines more resilient to distributional shifts and data growth.
