Publisher summary· verbatim

arXiv:2608.24982v2 Announce Type: replace-cross Abstract: Foundation-model post-training usually relies on human labels, preference data, stronger teachers, or executable verifiers. We study Unsupervised Post-Training (UPT): update-bearing adaptation on unlabeled inputs whose learning signal is deri
