Rethinking Local Learning: A Cheaper and Faster Recipe for LLM Post-Training
arXiv:2605.04913v4 Announce Type: replace-cross Abstract: LLM post-training typically propagates task gradients through the full depth of the model. Although this end-to-end structure is simple and general, it couples task adaptation to full-depth activation storage, long-range backward dependencies and direct task-gradient…
