Paper: Single-Layer Transformer Training May Rival Full-Parameter RL
heghbalz · x · 2026-07-06
This post highlights the paper "Is One Layer Enough? Training A Single Transformer Layer Can Match Full-Parameter RL Training". It explores whether training just one Transformer layer during RL post-training can achieve results on par with full-parameter training, pointing toward a more efficient path for reinforcement learning. The original text is an AlphaXiv abstract that was truncated due to length.
