The PPO stage keeps an actor, a critic, a frozen reference policy and a frozen reward model in memory at once, so it needs more than three times the memory of supervised fine-tuning. That puts it out of reach for many teams. The Microsoft authors measure how several memory-saving variants… ## All works 3 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1.
