"only" and "repeating" aren't accurate here. There's a lot of steps between the pretraining tokens and the LLM. I mean, you can pretty much do whatever you want

"only" and "repeating" aren't accurate here. There's a lot of steps between the pretraining tokens and the LLM. I mean, you can pretty much do whatever you want in the process of making one or running it. For instance you could use pretraining/SFT to steer something away from a document instead of towards it and that wouldn't be "only repeating" it. Though I don't know if that's actually possible, and afaik it is true RL reweights existing data instead of learning new things.
