The RL Fine-Tuning Playbook: CoreWeave's Kyle Corbitt on GRPO, Rubrics, Environments, Reward Hacking
Erik TorenbergNathan LabenzKyle Corbitt
RL can push capable open-weight models higher by reinforcing rare outcome-changing decisions while preserving pretrained “grooves,” unlike SFT’s broader risk of catastrophic forgetting.For enterprise agents, the clearest wedge is latency: RL can bring small models to roughly 30% of frontier latency and improve cost per token by at least an order of magnitude, though slower iteration and reward hacking remain risks.
