Researchers have developed Adaptive Importance Sampling (AIS) to address the training instability caused by using low-precision rollouts in reinforcement learning for large language models. This technique dynamically adjusts the gradient correction based on real-time diagnostics, balancing exploration benefits with bias reduction. When integrated with models like LLaDA-8B-Instruct and Qwen3 series, AIS maintained performance comparable to higher-precision training while preserving significant speedups from low-precision generation.
