RL is more information inefficient than you thought
Recently, people have been talking about how it takes way more FLOPs to get a single sample in RL than it does in supervised learning. In pretraining, you get a signal on every single token you train on. In RL, you have to unroll a whole thinking trajectory that’s 10s of 1000s of tokens long […]
