Title: Dual-objective Language Models: Training Efficiency Without Overfitting

Abstract:
arXiv:2512.14549v3 Announce Type: replace-cross Abstract: This paper combines autoregressive and masked-diffusion training objectives without any architectural modifications, resulting in flexible language models that outperform single-objective models. Autoregressive modeling has been a popular approach, partly because of its training efficiency; however, that comes at the cost of sensitivity to overfitting. On the other hand, masked-diffusion models are less efficient to train while being more
