Introspective X Training: Feedback Conditioning Improves Scaling Across all LLM Training Stages

Brandon Cui, Ximing Lu, Jaehun Jung +7

We tackle the question of how to scale more efficiently across the many, ever-growing stages of current LLM training pipelines. Our guiding intuition stems from the fact that the d…

RLP: Reinforcement as a Pretraining Objective

Ali Hatamizadeh, Syeda Nahida Akter, Shrimai Prabhumoye +5

The dominant paradigm for training large reasoning models starts with pre-training using next-token prediction loss on vast amounts of data. Reinforcement learning, while powerful…
