Reinforcement Learning with NVIDIA NeMo-RL: Reproducing a DeepScaleR Recipe Using GRPO
Reinforcement learning (RL) is the backbone of interactive AI. It is fundamental for teaching agents to reason and learn from human preferences, enabling multiturn tool use, and much more. This post introduces NVIDIA NeMo-RL, a new open source post-training library that is built to support everything from single-GPU prototypes to thousand-GPU large models and to orchestrate multicomponent RL pipelines with ease.
