Deep Dive into KL Estimators in RL: k3 Gradient Is Wrong, Sequence KL Gradient Is Wrong Too—Corrected Derivation
Published Jul 25, 2026The author uncovers that popular KL estimators in RL losses, such as the k3 estimator used in DeepSeek, have incorrect gradients: k3's gradient actually estimates forward KL instead of reverse KL. Sequence-level KL also has a gradient mismatch. A blog post provides correct definitions and computational tricks to reduce complexity using .cumsum and a stop-gradient hack.
